A medical image is useful only when it is good enough to answer the clinical question. Two providers may both offer MRI or CT, yet produce examinations with very different diagnostic value.
Not all scans are equivalent
Image quality is influenced by scanner hardware, coils, patient positioning, motion, contrast timing, field of view, slice thickness, sequence selection, post-processing and radiologist expertise. The name of the scan is only the beginning. You can read more on the Best not Standard: Why we chose a different approach to advanced radiology and regenerative medicine here.
What determines image quality
Image quality is the result of decisions made before, during and after the scan. A very fast examination may omit sequences that are important for the specific condition. Thick slices may miss small lesions. Poor fat suppression can hide marrow or soft-tissue disease. Motion can obscure detail. A technically impressive image can still be unhelpful if the wrong sequence was acquired.
In-house protocol development
At MBR Health, selected MRI protocols use sequences and combinations developed or refined in-house around specific clinical questions. These are not simply standard vendor presets. Examples include thin high-resolution musculoskeletal sequences, nerve-focused imaging, diffusion-weighted imaging with distortion control and tailored post-treatment assessment. Availability and protocol design vary between providers.
Why this matters in cancer and preventative imaging
The major risk of a low-quality screening examination is not only a false alarm; it is false reassurance. Whole-body MRI for cancer screening requires appropriate anatomical coverage, diffusion-weighted imaging, fat suppression, distortion management, targeted additions where indicated and experienced interpretation. No whole-body scan replaces dedicated screening for every cancer.
Why this matters in musculoskeletal and nerve imaging
Subtle tendon, cartilage, ligament, marrow and nerve abnormalities can be affected by slice thickness, orientation, fat suppression and field of view. A protocol designed for a routine joint examination may not adequately answer a specialised nerve or post-treatment question.
Why this matters in Spectral CT
Spectral CT can increase the information available from a CT acquisition, but the benefit depends on the indication, contrast timing, reconstruction choices and interpretation. Technology alone does not make every examination diagnostic.
MBR Health’s position
Image quality is a patient-safety issue. A technically poor or incomplete examination may delay diagnosis, misdirect treatment, require repetition or create false reassurance. The aim is not the shortest possible scan; it is the scan that best answers the clinical question.

Frequently Asked Questions
For other FAQs please visit our FAQs page
Is a longer scan always better?
No. Longer does not automatically mean better. The important question is whether the examination includes the necessary sequences at adequate quality.
Does a 3T MRI guarantee a better scan?
No. A 3T system can provide more signal, but protocol design, patient preparation, motion control and interpretation remain critical.
Can a poor-quality scan be repeated?
Sometimes, but repeating a scan adds cost, delay and—when ionising radiation is involved—additional exposure. It is preferable to perform the appropriate examination well the first time.
| Important: Comparisons between providers should consider the full protocol and clinical expertise, not the scanner name alone. |
