Abstract To study the effect of magnetic resonance Imaging(MRI) and ultrasound for diagnosing the female pelvic primary tumor. Methods: A retrospective analysis was performed on the clinical data of 66 patients with the female primary pelvic tumor confirmed by surgery and pathology from August 2017 to December 2022. The detection rate and the sonographic features of the patients were compared between MRI and ultrasound for diagnosing the female pelvic primary tumor. Results: Among 66 patients with primary pelvic tumors confirmed by pathology after surgery, there were 18 cases with cervical cancer, 9 cases with ovarian cancer, 22 cases with uterine fibroids and 17 cases with ovarian cysts. The accuracy rates of the patients diagnosed by MRI based on the results of pathology after surgery included 100.0% for cervical cancer(18 cases), 88.9% for ovarian cancer(8 cases), 100.0% for uterine fibroids(22 cases), and for 100.0% ovarian cysts(17 cases). The accuracy rates of the patients diagnosed by ultrasound based on the results of pathology after surgery included 77.8% for cervical cancer(14 cases), 55.6% for ovarian cancer(5 cases), 77.3% for uterine fibroids(17 cases), and 76.5% for ovarian cysts(13 cases). The accuracy rates of diagnosis of cervical cancer, uterine fibroids and ovarian cysts of the patients by MRI were significantly higher than those by ultrasound(P<0.05). The imaging features of the cervical cancer by MRI showed that the volume of the tumor was irregularly increased or heterogeneous strong signal. After the enhanced scanning by MRI, the early pelvic primary tumors had showed the obvious enhancement, and the signal was gradually weakened, while the signal of the advanced tumors was stronger, and the signal was significantly stronger than that of the normal cervical tissue. The imaging features of the endometrial cancer by MRI showed that the volume of the tumor was irregularly increased and had affected the lateral wall of the uterus. The imaging features of the cervical cancer by ultrasound examination showed that the uterine volume increased obviously, and the contour of the uterus was rules. The imaging features of the endometrial cancer by ultrasound examination showed that the tumor margins were indistinct and irregularly shaped. The imaging features of the uterine fibroids by both MRI and ultrasound showed that the uterine volume increased obviously and the uterine morphological abnormality. The imaging features of the ovarian cysts by both MRI and ultrasound examination showed that the non-uniform thickening of the ovarian cysts and the cystic wall inside and outside with the visible nipple swelled. Conclusion: MRI has a high diagnostic value for the female pelvic primary tumors, which can help to provide the choice of the appropriate treatment plan in clinic.
