To evaluated usefulness of MR in assessment of tumor response to the chemotheraphy, we prospectively studied cases of cervical carcinoma with more than 2.5cm in diameter or stage IIb or more. Three courses of chemotherapy were lperformed with cisplatin and 5 F-U. MR images were obtained both before and after chemotherapy. Nine of 13 patients were undertaken radical hysterectomy after chemotherpy and MR examination. MR volumetry, stage and depth of stromal invasion were compared before and after chemotherapy. And in 9 patients who underwent radical hysterectomy, comparison of pathologic and MR imaging findings were also done. The results were following : 1) All tumors dectrases in volume (m=80.5%). 2) Five tumors (38.5%) reduced in stage, IB longrightarrow CIS (1); IIA longrightarrow CIS (1), IIA longrightarrow IB(2), IIB longrightarrow IB(1). 3) Depth of stromal invasion in MRI correlated well with that of histo-pathologic specimen in 7 of the 9 patients. Conclusively MR imaging is useful in assessement of tumor response to chemotherapy.
