Özet:

 


Objective: Magnetic resonance (MR) imaging is a helpful modality for detecting and
staging gynecological cancers. Diffusion-weighted imaging (DWI) could improve
the accuracy rates of MR imaging. The aim of this study was to assess the
additional diagnostic value of DWI over conventional MR imaging in assessing
the local extent of primary cervical cancer. 


Method: Forty
patients with primary uterine cervical cancer were enrolled in the study,
prospectively.
All MR examinations were performed using a 1.5 Tesla
Unit MR with a body coil. Sagittal and axial T2-weighted MR images, sagittal
and axial DWI (at b values of 0, 500,1000 s/mm2) with ADC maps were
obtained. The images were evaluated by two different readers independently. The
degree of the interobserver agreement between the radiologists was assessed
with kappa statistics.


Results: Mean age of
the study population was 50.7±11.1 years. Kappa values ranged from 0.76 to 1
for both readers indicating excellent agreement. Accuracy rates were as follows
for reader 1 respectively with conventional and conventional plus DWI; stromal
invasion 0.92/0.95; parametrial invasion 0.87/0.92; vaginal invasion 0.87/0.92;
pelvic sidewall invasion 0.90/0.97. Accuracy rates were as follows for reader 2
respectively with conventional and conventional plus DWI images; stromal
invasion 0.90/0.95; parametrial invasion 0.87/0.92; vaginal invasion 0.87/0.97;
pelvic sidewall invasion 0.90/0.95. 









Conclusions: MR provides satisfactory accuracy rates in the
evaluation of the local extent of uterine cervical carcinoma, and adding DWI
improves the diagnostic performance of conventional MR.
