Objective : To assess the role of magnetic resonance imaging in the diagnosis of gynaecological pelvic tumours.
Design: Prospective study.
Setting : Tanta University Hospitals .
Patients : The study included 49 women diagnosed clinically as having pelvic tumours.
Intervention: All the patients were subjected to history laking, physical examination, transabdominal and/or
transvaginal ultrasound, pelvic MRI and pathological examination of the specimens.
Outcome measures: Specificity of MRI in diagnosis of gynecologic pelvic tumours.
Results: We found that the specificity of MRI in the diagnosis of uterine fibromyomata and adenomyosis was 100%. In
cases of malignant uterine tumours, we found that MR was the imaging modality of choice in crarly diagnosis and
staging of cndomctrial carcinoma as it exhibits if there is myometrial invasion or not. Ultrasound was false negative in
40% of cndomctrial carcinoma. Both ultrasound and MRI were equivocal in diagnosis of benign ovarian lesions, but
MRI was superior to ultrasound in diagnosis of benign cxtraovarian lesions. MRI succeeded in diagnosis of the
pathological pattern of benign ovarian lesions and in the discrimination between benign and malignant ovarian tumours.
Conclusion: MR imaging is a valuable modality in the evaluation of female pelvic tumours when the sonographic
diagnosis is nonspecific.
