Purpose : To compare the sensitivity and staging accuracy of dynamically enhanced
MR imaging(hereafter, DEI) and turbo spin-echo(TSE) T2-weighted imaging(hereafter,
T2W1) in cases of cervical carcinoma.
Materials and Methods : MR images(T2Wl and DEI) of 25 cervical carcinoma patients,
diagnosed during surgery, were reviewed by two radiologists. T2W1 employed the TSE
technique:dynamic MR imaging, the FLASH technique in the axial plane. DE images
were obtained immediately and at 30, 60, 120, and 180 seconds after rapid injection of
GD-DTPA. The degree of visualization of the tumor, and its invasiveness, were graded
as graded as good, fair, or poor. By correlating the histopathologic results, the accuracy
of the two MR imaging techniques was compared.
Results : For tumor visualization, T2Wl was good in 13/25 cases (52%), fair in
3/25(12%), and poor in 9/25(36%) ; DEI was good in 5/25(20%), fair in 7/25(28%), and
poor in 13/25 cases (52%).
Conclusion : For the detection and staging of cervical carcinoma, T2Wl is superior to
DEI. For the diagnosis and staging of cervical carcinoma, DEI is therefore
unnecessary.(J Korean Radiol Soc 1998: 38:329-333)
