The purpose of this study was to evaluate the characteristic findings of cervical carcinoma in dynamic MR imaging with a turbo-FLASH technique and to investigate the cause of the hyperintense rim surrounding the tumor on dynamic MR images by comparing them with the pathological findings in the resected specimens. Sixty consecutive patients with cervical carcinoma were included in this study. Dynamic MR imaging was performed with the rapid administration of Gd-DTPA using the turbo-FLASH technique. After dynamic MR imaging, T1-weighted spin echo (SE) images were obtained. Dynamic patterns of the lesions were investigated from images acquired in the early and late phases of dynamic MR imaging. The causes of the hyperintense rim were investigated by comparing dynamic MR images with the pathological findings. Most of the cervical carcinomas showed higher signal intensity than normal cervical stroma in the early phase of dynamic MR imaging. The pathological findings of the hyperintense rim on dynamic MR images differed according to the time of appearance of the hyperintense rim. Dynamic MR imaging with the turbo-FLASH technique, which shows high contrast between the lesion and normal cervical stroma, should be performed before obtaining contrast- enhanced T1-weighted SE images in patients with cervical carcinoma.
