PDFAbstract
Objective To explore the value of diffusion-weighted MRI in differentiating ovarian solid tumors. Methods 41 patients with pathology proven ovarian solid tumors, who had conventional MRI and DWI scanning preoperatively. The basic MR features(location, amount and shape), signal intensity characteristics of conventional MRI and DWI were compared. The size and ADC values of all ovarian tumors were calculated. Student's t test to compare the difference between benign ovarian tumors and malignant ones in size and ADC value. Results Of this group, there were 51 ovarian tumors(23 benign and 28 malignant masses). It is no statistical significance between the size, ADC values of the benign and malignant ovarian tumors (P=0.356,0.082). Conclusion The difference between ADC values of the benign and malignant ovarian tumors was no statistical significance. DWI combined with the conventional MRI is probable to provide the useful information.
