CT-Guided Spinal Injections Gold Coast

Specialist spine radiology, advanced imaging and precision CT-guided treatment for selected back pain, neck pain, sciatica and spinal pain pathways.

Spinal injections are not simply about putting medication somewhere near the area that hurts.

The spine contains discs, facet joints, nerve roots, ligaments, the epidural space and small sensory nerves positioned within millimetres of one another. Different structures can produce very similar symptoms, and abnormalities on an MRI do not necessarily identify which structure is actually causing pain.

At MBR Health on the Gold Coast, CT-guided spinal injections sit within a diagnosis-led back and neck pain pathway.

The aim is to first determine the most likely pain generator, then select the appropriate treatment and deliver it accurately to the intended anatomical target.

Specialist Spine Radiology Before Spinal Treatment

The injection should not be the starting point.

Back pain, neck pain and sciatica are symptoms rather than diagnoses.

Pain may arise from:

an irritated or compressed nerve root
a disc protrusion or annular injury
facet joint degeneration or inflammation
foraminal or spinal canal narrowing
sacroiliac joint pathology
ligamentous injury
post-surgical change
or several abnormalities occurring together.

This matters because a technically successful injection into the wrong structure may still be clinically unsuccessful.

At MBR Health, spinal assessment can incorporate advanced 3T MRI, specialised nerve imaging including MRI NerveVIEW, MRI discography and Spectral CT, depending on the clinical question.

The purpose is not simply to identify abnormalities.

It is to determine which abnormality is most likely to matter.

For a more detailed overview, see our guide to advanced imaging for back pain, neck pain and sciatica.

What Is a CT-Guided Spinal Injection?

A CT-guided spinal injection is an image-guided procedure in which computed tomography is used to identify the treatment target and guide the needle into the required position.

A small planning CT is performed and the radiologist selects an appropriate pathway to the target.

The needle position can then be confirmed with imaging before treatment is delivered.

This is particularly valuable in the spine because the structures being treated are small and lie close to nerves, blood vessels, bone and other important anatomy.

In spinal intervention, precision is part of treatment quality.

CT-Guided Spinal Procedures at MBR Health

Depending on the diagnosis and referral, specialist spinal procedures may include:

CT-Guided Nerve Root Injections

A targeted injection around a selected spinal nerve root may be considered when symptoms and imaging indicate radicular pain or sciatica arising from irritation of a specific nerve.

This may occur with conditions including disc herniation, foraminal narrowing or other causes of nerve-root inflammation or compression.

CT-Guided Epidural Injections

An epidural injection places medication into the epidural space surrounding the spinal nerves.

Depending on the clinical problem and anatomy, the target and approach can be selected to address a particular region of nerve inflammation rather than treating back pain as a single generic condition.

CT-Guided Facet Joint Injections

Facet joints are small joints at the back of the spine.

When imaging and the clinical pattern suggest that a facet joint may be contributing to pain, a precisely targeted facet injection may be used as part of diagnosis or treatment.

Medial Branch Blocks

The medial branches are small sensory nerves supplying the facet joints.

A diagnostic medial branch block may help determine whether facet-mediated pain is genuinely responsible for persistent neck or back pain before longer-lasting treatments such as radiofrequency ablation are considered.

You can read more about diagnostic blocks and other specialist diagnostic procedures at MBR Health.

Sacroiliac Joint Injections

The sacroiliac joints can produce pain that overlaps with lower lumbar, buttock and hip symptoms.

Image guidance allows treatment to be accurately delivered into the intended joint when the clinical and imaging findings support it as a potential pain generator.

Radiofrequency Ablation

For appropriately selected patients with confirmed facet-mediated pain, radiofrequency ablation may be considered to reduce pain signalling from the relevant sensory nerves.

Our broader image-guided pain management service also includes selected corticosteroid, radiofrequency ablation and pulsed radiofrequency pathways.

Regenerative Spinal Injections

MBR Health also provides selected regenerative spine treatments, including platelet-rich plasma (PRP) therapy where clinically appropriate.

These treatments have a different objective from corticosteroid injections.

Rather than primarily suppressing inflammation for temporary symptom relief, regenerative approaches aim to influence the biological environment of injured tissue. The available evidence varies considerably according to the spinal structure, treatment and indication, making careful patient selection particularly important.

For a more detailed discussion, read Treating Spinal Pain: A Precision Framework for PRP and Biologic Spine Treatments.

Why CT Guidance?

The spine is not a structure where “close enough” should be the objective.

CT provides cross-sectional visualisation of spinal anatomy.

This can be especially useful where the target is:

deep
very small
immediately adjacent to bone
close to a nerve root
within complex degenerative anatomy
or altered by previous surgery.

CT guidance also creates an imaging record documenting needle position during the procedure.

At MBR Health, spinal procedures are performed within a specialist radiology environment where the diagnostic imaging and intervention can be considered together.

That is an important distinction.

The person performing the procedure is not simply treating a referral label such as “back pain”. The relevant imaging can be reviewed, the anatomy understood and the procedural target correlated with the clinical question.

CT-Guided Spinal Injections for Back Pain

Back pain is one of the most common medical symptoms, but most episodes do not require an injection.

Spinal intervention may be considered when symptoms are persistent, functionally limiting or associated with a more clearly defined pain generator.

Examples may include:

lumbar radicular pain or sciatica
facet-mediated lower back pain
selected disc-related pain pathways
recurrent pain despite appropriate conservative management
persistent symptoms following spinal surgery
sacroiliac joint pain
or situations where a diagnostic injection may help clarify the pain source.

A referral and appropriate clinical assessment are required.

If the pain generator remains uncertain, the quality of the underlying imaging becomes particularly important. Our article on how to choose a high-quality MRI provider explains why two examinations carrying the same name may not necessarily provide the same diagnostic information.

CT-Guided Spinal Injections for Neck Pain

Cervical spinal procedures require particular attention to anatomy because neural and vascular structures are closely positioned within the neck.

Persistent neck pain may arise from facet joints, discs, nerve roots or other structures.

When intervention is appropriate, imaging is used to define the target and guide treatment accurately.

Patients with arm pain, tingling, numbness or weakness should first undergo appropriate clinical assessment to determine whether nerve-root compression or another neurological condition may be present.

Sciatica and Nerve Root Pain

Sciatica describes pain radiating from the lower back or buttock into the leg, commonly associated with irritation or compression of a lumbar nerve root.

MRI can demonstrate abnormalities such as:

disc protrusion or extrusion
lateral recess narrowing
foraminal stenosis
nerve-root compression
inflammation
and post-surgical change.

However, many patients have more than one abnormality on their scan.

The challenge is determining which abnormality corresponds with the symptoms.

This is why MBR Health combines specialist spine imaging with targeted precision interventional radiology rather than treating the scan and the injection as completely separate processes.

Not Every Spinal Injection Should Be Cortisone

Corticosteroid injections have a role in selected inflammatory pain pathways, but they are not the answer to every form of spinal pain.

Different problems require different treatment objectives.

Where inflammation around a nerve is dominant, corticosteroid may have a role.

Where facet-mediated pain is confirmed, diagnostic blocks and potentially radiofrequency treatment may be more appropriate.

Where damaged tissue itself is being considered as a treatment target, a regenerative approach may be discussed in selected patients.

And sometimes the correct decision is not to perform an injection at all.

The treatment should follow the diagnosis rather than the other way around.

Why MBR Health for Spinal Injections on the Gold Coast?

Diagnosis and treatment exist in the same specialist radiology environment.

MBR Health combines:

Specialist Radiologist-Led Procedures

Spinal procedures are undertaken within a specialist radiology environment with access to the patient’s diagnostic imaging and spinal anatomy.

Advanced 3T Spine MRI

Our 3T MRI service provides high-resolution assessment of discs, nerve roots, facet joints, ligaments, marrow and surrounding soft tissues.

MRI NerveVIEW

Selected patients can undergo specialised nerve imaging where conventional anatomical imaging does not fully explain neural symptoms.

Spectral CT

Advanced Spectral CT can provide detailed assessment of spinal bone, facet joints, stenosis, hardware and complex post-surgical anatomy.

Precision CT Guidance

CT guidance enables the treatment target and needle position to be directly visualised and documented.

Diagnostic and Therapeutic Options

MBR Health provides conventional image-guided pain interventions as well as selected PRP and regenerative treatment pathways, allowing the treatment objective to be matched to the diagnosis rather than applying the same injection to every patient.

The MBR Health Approach

Diagnose → Target → Treat → Reassess

Our approach to spinal intervention is deliberately simple.

Diagnose – Identify the most likely pain generator using the clinical history and appropriate imaging.

Target – Determine the precise anatomical structure most likely to be responsible for the symptoms.

Treat – Select an intervention that matches the pathology and treatment objective.

Reassess – Evaluate the clinical response rather than automatically repeating the same procedure. This is particularly important in chronic spinal pain, where repeated non-specific treatment can delay reconsideration of the underlying diagnosis.

What Happens During a CT-Guided Spinal Injection?

The exact procedure depends on the treatment being performed.

In general:

1. Your referral and relevant imaging are reviewed.

2. You are positioned on the CT table according to the target.

3. A limited planning CT identifies the treatment pathway.

4. The skin is cleaned and local anaesthetic is administered where appropriate.

5. A fine needle is advanced under CT guidance.

6. Needle position is confirmed.

7. The selected medication or treatment is delivered.

8. You are observed according to the procedure performed before leaving the clinic.

Some spinal procedures can temporarily produce numbness or weakness, particularly when treatment is performed close to a nerve root. Driving and post-procedure requirements therefore vary according to the procedure.

You will receive procedure-specific instructions before and after treatment.

For further information about procedural risks, read Risks and Limitations of Image-Guided Procedures.

If you have already had an injection, our guide to pain, numbness and weakness after an injection explains common short-term symptoms and the warning signs that require medical attention.

Do I Need an MRI Before a Spinal Injection?

Not every patient requires a new MRI.

However, good-quality recent imaging is often important when treatment depends on identifying a specific spinal target.

If previous imaging does not adequately explain the symptoms, or if the anatomy has changed following surgery or injury, additional imaging may be appropriate before an intervention is performed.

At MBR Health, having advanced spine imaging and interventional radiology within the same service allows the diagnostic question to be reconsidered before treatment if necessary.

What Is the Best Spinal Injection for Back Pain?

There is no single “best spinal injection”.

The correct procedure depends on the pain generator.

A nerve-root injection, epidural injection, facet injection, medial branch block, radiofrequency treatment and regenerative injection all target different anatomical or biological problems.

The more useful question is:

What structure is causing the pain, and which treatment best matches that structure?

That is why accurate diagnosis should come before intervention.

Frequently Asked Questions

Are CT-guided spinal injections more accurate?

CT allows the radiologist to directly visualise cross-sectional anatomy and confirm the location of the needle relative to the intended spinal target. The most appropriate guidance method depends on the procedure and anatomy, but CT can be particularly useful for small or deep spinal structures and complex post-surgical anatomy.

Can a CT-guided injection help sciatica?

Selected patients with radicular pain or sciatica may benefit from a targeted spinal injection when clinical assessment and imaging identify inflammation or irritation of a particular nerve root. An injection is not appropriate for every cause of sciatica.

What is the difference between a nerve root block and an epidural?

A nerve-root injection is directed specifically around an individual spinal nerve root. An epidural injection delivers treatment into the epidural space. The most appropriate approach depends on the location and mechanism of the symptoms.

What is a facet joint injection?

A facet injection targets one of the small joints at the back of the spine. It may be considered when the clinical pattern and imaging suggest facet-mediated neck or back pain.

What is a medial branch block?

A medial branch block places local anaesthetic around the small sensory nerves supplying a facet joint. The response can help determine whether the facet joint complex is responsible for the patient’s pain and whether radiofrequency ablation may subsequently be appropriate.

Are spinal injections painful?

Most procedures are performed using local anaesthetic. Patients may feel pressure or brief discomfort, although the experience varies according to the target and individual anatomy.

How long does a spinal injection take?

The procedure itself is generally relatively short, although appointment time also includes preparation, imaging review and any required observation afterwards.

Do spinal injections cure back pain?

No spinal injection can be expected to cure every form of back pain. Some treatments are intended to reduce inflammation or pain temporarily, others help confirm a diagnosis, and selected regenerative procedures have a different biological objective. Outcomes depend on the underlying pathology and patient.

Do I need a referral?

Yes. Imaging and interventional procedures at MBR Health require an appropriate referral from a GP or specialist.

How do I choose the best spinal injection clinic on the Gold Coast?

Rather than relying on the word “best”, useful questions include whether the procedure is image guided, who performs it, whether the clinician can review the underlying MRI or CT, whether the precise treatment target is documented, and whether the proposed intervention matches the suspected pain generator.

A spinal injection should be part of a diagnostic pathway — not simply a procedure performed because back pain exists.
