Abstract

Introduction. Magnetic resonance (MR) imaging showed high reliability in detecting spine metastases with spin-echo (SE) sequences, T1-weighted sequences being generally more sensitive than T2-weighted ones. We investigated the value of T2 *-weighted gradient-echo (GE) sequences in studying spine metastases. Materials and methods. Twenty patients with established diagnosis of primary carcinoma and clinically suspected thoracic and/or lumbosacral spine metastases underwent .5-T MR imaging and 99mTc-HDP bone scan.The disagreement of GET2 *- versus SET2-weighted images as well as versus bone scan and the disagreement of total MR results versus bone scan results were evaluated by McNemar test, The agreement of GET2 *- versus SET1-weighted images was evaluated by Cohen's kappa. Results. Of a total of 111 MR signal abnormalities consistent with metastasis, 109 (98.2%) were T2 *-hyperintense, whereas only 50 (45.1%) were T2-hyperintense (p
