Summary

Up to 30% of patients with newly diagnosed/suspected myeloma cannot undergo or do not tolerate whole body MRI (WB-MRI). A number of factors may be contributory. First, WB-MRI protocols can take in excess of 1 hour. Patients must remain still within a narrow bore scanner with multiple MRI coils that can be claustrophobic. Second, there is significant acoustic noise that can be heard despite the use of ear protection. Third, 80% of patients will experience bone pain or fracture at some point during their illness, affecting their comfort within the scanner. Fourth, patients also have higher anxiety. One review reported up to 30% of patients experienced considerable apprehension and up to 10% severe psychological distress when undergoing MRI. Finally, myeloma is predominantly an illness of the elderly and co-morbid conditions decrease patients' ability to tolerate a long scan. When WB-MRI cannot be performed, NICE recommend whole-body computed tomography (WB-CT), which the investigators know offers decreased diagnostic performance in terms of marrow assessment and focal lesion detection. The investigators believe that using a novel CT technique - dual-energy CT (DECT) - may offer better diagnostic performance over standard WB-CT in myeloma patients.

What the investigators seek to do in this study is to evaluate the sensitivity and specificity of DECT in a cohort of untreated patients; and compare the performance of DECT to simulated standard CT (data simulated from the DECT) and also to WB-MRI (reference standard alongside bone marrow biopsy results. The investigators will assess both subjective visual analysis of DECT images as well as CT quantitative values for the bone marrow.

Secondary objectives include assessment of patient experience across both imaging tests and assessment of intra \& inter observer variability in subjective visual analysis

Conditions

Interventions

RADIATION

Whole Body MRI

Once recruited, the participant will undergo a WB-MRI scan as part of their usual standard-of-care. As part of the research study, the participant will be consented to undertake an additional WB-DECT research scan at a time of their choosing (on the same day as the MRI scan, or on another day, if preferred)
