An Observational Study to Evaluate the Role of Dynamic Contrast Enhanced Magnetic Resonance Imaging and Diffusion Weighted Imaging in Evaluation of Ovarian Tumors

Abstract

Aim: The aim of the present study was to assess the ability of dynamic contrast-enhanced MRI (DCE–MRI), and Diffusion-weighted image (DWI) to describe uncertain ovarian masses.

Methods: The present study was conducted in the Department of Radiology, Gouri Devi Institute of Medical Sciences and Hospital, Durgapur, West Bengal, India and we did transabdominal ultrasound and transvaginal ultrasound for all cases. We investigated 50 patients with 50 adnexal lesions.

Results: The patients ranged in age from 20 to 78, with a mean of 43.56. Patients worried most about stomach pain and distension. Some cases showed subfertility or abnormal vaginal haemorrhage. Histopathology showed 21 benign, 4 borderline, and 25 malignant tumours. The age range of patients diagnosed with benign tumours was 20-65 years, with a mean age of 39 ± 13 years. However, patients with malignant tumours had an average age of 46 ± 16.953 years, with a mean age of 78 years. The benign tumours included seven serous cystadenoma, six mucinous, three mature cystic teratoma, two ovarian fibromas and fibrothecomas, and one tubo-ovarian abscess. We found four borderline tumors—two serous and two mucinous. The study found 25 invasive malignant masses, including nine serous cyst-adenocarcinomas, six mucinous cysts, three metastatic krukenburgs, three immature teratomas, two fibrosarcomas, and two clear cell carcinomas.

Conclusion: DCE-MRI and DWI have accepted ability to distinguish between benign and malignant ovarian mass.
