Systematization of the magnetic resonance protocol for primarily identified pelvic malignant masses in women

Introduction. The purpose of the investigation is to systematize MRI protocols for primarily identified malignant masses in women’s pelvis.

Materials and methods. The retrospective analysis included 1.5 T MRI of 530 women’s pelvis. The analysis included uterine cervical cancer, uterine corpus malignancy, ovarian cancer and rectal cancer. Three MRI oncology experts, with over 5 years of experience, have performed a retrospective analysis of scanning protocols and their significance in identifying local extent of metastatic lesion.

Results and discussion. In rectum cancer, corpus uteri or uterine cervical cancer MRI is used as a method to assess local extent, pelvic lymph nodes and, in some cases, paraaortic lymph nodes. The authors have suggested MRI protocols to solve these problems. The authors discuss the MRI scanning protocol for primarily identified neoplasms in rectum, uterus, uterine cervix and ovaries. It also considers the application of necessary sequences, details of useful axis with indication of evaluated structures.

Conclusions. The complex application of different methods improves diagnostic significance for multiparametric pelvic MRI in female patients. In experts’ opinion, the complex implementation of diffusion methods and dynamic contrast enhancement significantly improve the results of traditional MRi scanning for ovarian neoplasms and uterine corpus cancer. Different contrast methods do not provide necessary information for primarily identified colorectal cancer and cervical uterine cancer.
