Aim
WB-MRI provides a fast, highly sensitive assessment of disease burden in myeloma. The 2015 International Myeloma Working Group consensus statement recommends WB-MRI for staging asymptomatic myeloma and for workup of solitary bone plasmacytoma. The technique is noisy, employs whole body surface coils, and takes longer than a standard MRI spine. We assessed patient experience of WB-MRI and identified causes for incomplete examinations.
Methods
36 consecutive patients undergoing WB-MRI for myeloma (whole body DWI and Dixon, fast T1w and T2w spine) were included. Patients anonymously completed a ten-question survey about their experience. The reporting radiologist recorded technical details and radiological findings.
Results
WB-MRI was well tolerated in most patients. 89% completed the protocol; kyphosis and claustrophobia were causes of incomplete studies. 85% found the scan ‘not at all unpleasant’ or ‘not too unpleasant’.
96% were satisfied with the quality of information provided to them prior to the examination. 93% had had a previous MRI and 86% were not worried about having WB-MRI. 93% would have a repeat study.
Average scan length was 48 minutes. Two-thirds of patients found this acceptable. 18% of patients cited claustrophobia as the reason for finding the examination too long. 44% of patients had chronic vertebral fractures, but this did not correlate with the level of discomfort experienced. Half of scans were positive for active disease.
Conclusions
Patients report a high level of satisfaction with WB-MRI at our institution. The protocol was completed in almost all patients, and most stated they would have a repeat study.
