The accuracy of nonenhanced spin-echo (SE) T2-weighted and contrast material-enhanced SE T1-weighted magnetic resonance (MR) imaging in assessing the degree local tumor invasion was determined prospectively 53 consecutive patients with clinically established early-stage carcinoma cervix. With a 0.5-T superconducting unit, pulse sequences 2,000/90 (repetition time msec/echo msec) for images 500/20 were used. In all cases, findings two MR techniques compared results histologic examination surgical specimens. Tumor infiltration into surrounding structures classified as partial stromal, complete or parametrial. Tumor-cervical stroma tumor-parametrium contrast-to-noise ratios (C/Ns) higher (P < .05) at than enhanced imaging. determining depth invasion, overall 85% 57% conventional sequences, is superior to contrast-enhanced invasiveness clinical cervical tumors.
