Abstract
MRI is an ideal non - invasive technique and superior to other imaging modalities in the evaluation of pelvic abnormalities. The anatomical relation of the visceral organs, the differential zonal anatomy of the corpus uteri, and the cyclical endometrial changes during the menstrual cycle are well depicted with MRI. Diffusion weighted imaging (DWI) is one of the evolving imaging technologies. It carries the potential to improve tissue characterization when findings are interpreted together with conventional MR imaging sequences. To evaluate the role of diffusion weighted magnetic resonance imaging (MRI - DWI) in the diagnosis of cervical carcinoma, with pathological diagnosis was taken as the reference. The study group consisted of 35 patients in whom cervical cancer had been suspected clinically or by Trans vaginal U/S and confirmed by biopsy and the control group consisted of 20 patients in whom cervical cancer had been not suspected and MRI was performed because of other pelvic diseases. Pelvic MR with DWI were done for all patient, DCE - MR was done for all patients. The patient{u2019}s age ranged from 38 to 82 years old and the control group age ranged from 17 to 72 years old. They presented with abnormal uterine bleeding, post menopausal bleeding and/ or vaginal discharge. MRI results were compared with the histopathology results. The calculated sensitivity, overall accuracy and positive predictive value of MRI in staging of cervical carcinoma was 100 %, 97%and 97% respectively
