Abstract
결론
MRI를 이용한 자궁경부암 환자의 병기결정은 74%의 정확성을 보였고, 자궁경부 조직 침
윤도의 정확성은 83%를 보여 자궁경부암 환자의 병기결정과 조직의 침윤도를 판별하는데
MRI가 유용할 것으로 생각되며, 종양의 크기에 관한 정확도는 60%, 자궁경부 기질의 침범
의 정확도는 66%를 보여 이에 관한 정확도를 증가시키기 위한 노력이 필요할 것으로 생각
되고 앞으로 자궁방 결합조직이나 임파절 전이에 대한 MRI의 정확도를 알아보기 위한 연구
가 더욱 진행되어야 할 것이다.

Purpose : Uterine cervical carcinoma is the most common cancer in Korean women.
We evaluated the accuracy of magnetic resonance(MR) imaging in determining the stage
and extent of disease in cervical carcinoma.
Materials and Methods : From January 1994 through December 1996, in all 35
patients, MR imaging was performed before any operative procedure. With a 1.57
superconducting magnet, TR(repetition time)/TE(echo time) of 483/9msec for
T1-weighted images and 3750/98msec for T2-weighted images were used. All patients
underwent radical hysterectomy or total abdominal hysterectomy and had detailed
histologic evaluation. MR image were reviewed and compared with pathologic findings
on the presence of tumor size, depth of stromal invasion and vagina extension.
Results : The accuracy of MRI in determination of stage was 74%. Its accuracy was
60% for the assessment of tumor size. Tumor size was underestimated in 6
patients(17%) and overestimated in 8 patients(23%). Tumor infiltration into the stroma
was classified as no, partial, complete. The accuracy of MRI in cervical stromal invasion
was 66%.
Conclusion : MR is a relatively promising method for staging and evaluating extent of
disease in carcinoma of the uterine cervix.
