Preoperative staging of cervical carcinoma: phased array coil fast spin-echo versus body coil spin-echo T2-weighted MR imaging.

Abstract

In the preoperative staging of cervical carcinoma by MR imaging, both the newer (phased array coil fast spin-echo protocol) and the older (body coil conventional spin-echo protocol) techniques achieved similarly high accuracies in local staging, assessment of parametrial invasion, and evaluation of tumor size. Decreased imaging time and increased image resolution are advantages of the newer technique, although in our series they did not increase staging accuracy.
