Comparative Study Controlled Clinical TrialSupplemental value of diffusion-weighted whole-body imaging with background body signal suppression (DWIBS) technique to whole-body magnetic resonance imaging in detection of bone metastases from thyroid cancer.
We compared the efficacy of whole-body MRI (WBMRI) with and without diffusion-weighted whole-body imaging with background body signal suppression (DWIBS) using a 3.0-T MR scanner to [18F] fluoro-2-D-glucose positron emission tomography with CT (integrated FDG-PET/CT) for the detection of bone metastases in patients with differentiated thyroid carcinoma (DTC). ⋯ Adding DWIBS improved the sensitivity and the overall accuracy of WBMRI using 3.0-T MRI for the detection of bone metastases in patients with DTC. There was no statistically significant difference in diagnostic accuracy between MRI with DWIBS and integrated FDG-PET/CT.

Diagnostic accuracy of whole-body diffusion-weighted magnetic resonance imaging with 3.0 T in detection of primary and metastatic neoplasms.
To discuss the accuracy of the whole-body diffusion-weighted imaging with background body signal suppression (WB-DWIBS) technique performed in the 3.0-T system. ⋯ WB-DWIBS is a non-invasive technique that may successfully detect the spreading of the tumoural tissue in cancer patients when compared with PET/CT.
