ABSTRACT

Objective: To analyze the diagnostic rate and imaging characteristics of MR diagnosis in female patients with pelvic malignant tumors. Methods: 105 female patients with pelvic malignant tumors diagnosed from August 2019 to August 2021 were selected. The detection rate, diagnostic accuracy and imaging characteristics of MR were analyzed based on the surgical and pathological results. Results: The detection rate of MR diagnosis was close to that of surgery and pathology, and there was no difference (P > 0.05). The accuracy, sensitivity and specificity of MR diagnosis were 98.10%, 99.01% and 75.00%, respectively. The imaging features of MR: irregular density shadow can be seen in the double attachments of ovarian metastatic cancer. On contrast-enhanced scan, the enhancement of bilateral masses was uneven, with vascular shadow inside and ascites shadow at the same time. Cervical cancer is mostly endogenous and the cervix shows increased volume, irregularity and uneven signal. Enhancing scanning, it showed that the tumor of early cervical cancer was significantly strengthened and the signal gradually weakened. The signal of late cervical cancer was strong, but the signal intensity was lower than that of normal cervical tissue. MR examination of endometrial carcinoma showed endometrial thickening involving the lateral wall of the uterus. Primary ovarian cancer had uneven density, unclear boundary, or enlarged lymph nodes. Conclusion: MR diagnosis can distinguish the disease types of female pelvic malignant tumors, with high diagnostic accuracy and clear imaging characteristics.
