- Abstract:
- Abstract: Objective To study the value of magnetic resonance imaging (MRI) combined with diffusion-weighted imaging (DWI)
in the diagnosis of ovarian tumors in the elderly, and to discuss its clinical significance. Methods A retrospective analysis was
performed on the data of 130 patients who received treatment for ovarian tumors during January 2013 to December 2017. The
patients aged from 60 to 78 years old. Before operation, all patients are scanned withMRI and DWI and received CT examination.
The imaging findings and apparent diffusion coefficient (ADC) values of ovarian tumors were analyzed. Using the postoperative
histopathological results as the gold standard, the values of MRI, DWI and CT in the diagnosis of ovarian tumors were evaluated.
Results Based on the diagnostic criteria of histopathological results, the sensitivity, specificity and accuracy ofMRI in the diagnosis
of benign and malignant ovarian tumors were significantly higher than those of CT (P<0.05). The ADC value (×10-3 mm2/s) of
malignant ovarian tumors was significantly higher than that of benign ovarian tumors (0.92±0.32 vs 1.52±0.31, P<0.05). The
accuracy rate ofMRI combined with DWI in the staging of ovarian tumors was significantly higher than that of CT (89.2%vs 80%,
P<0.05). Conclusion The accuracy of MRI and DWI in the diagnosis of benign and malignant ovarian tumors is superior to that
of CT, indicating thatMRI combined with DWI have important clinical significance in the diagnosis of ovarian tumors in the elderly.
