[Whole-body ssFSE-IR MR imaging in the detection of bone metastases]

Preliminary studies were performed to evaluate the usefulness of whole-body MR imaging using the inversion recovery single shot fast spin echo (ssFSE-IR) sequence in the detection of bone metastases. Two sets of coronal ssFSE-IR images (ssSTIR: TI = 150, ssT1W: TI = 550) were obtained for four body segments without respiratory triggering or ECG/peripheral gating. In 8 patients with bone metastases, all lesions were easily detected on both sets of images; lesions showed high signal intensity on ssSTIR and markedly low signal intensity on ssT1W.
