Abstract:

BACKGROUND: Imaging performance of ovarian tumor has diversity and variability. Therefore, accurate qualitative diagnosises cannot be obtained from the current imaging methods.
OBJECTIVE: To perform the three-dimensional reconstruction of the pelvis in patients with different types of ovarian tumor so as to obtain digital anatomical models and then to explore its value in surgical selection using medical image three-dimensional visualization system of the abdomen.
METHODS: Pelvic CT data of 65 hospitalized patients with ovarian tumor were collected and classified into benign tumor group (30 cases), malignant tumor group (25 cases) and borderline tumor group (10 cases) according to pathological results after treatment. The data obtained from 64-slice helical CT angiography were used for the three-dimensional reconstruction using the medical image three-dimensional visualization system to harvest three-dimensional virtual models of ovarian tumor. According to the vascular distribution, walking and branch in tumor, tumor blood flow was divided into type Ⅰ, type II and type Ⅲ. ①The tumor vessels of type Ⅰ were curved or short bar-shaped around the tumors, which could not be seen within the tumors. ②The tumor vessels of type Ⅱ were sparse in tumors besides around the tumors, and vascular branch was simple and straight. ③The tumor vessels of type Ⅲ were abundant or vascular network could be seen within the tumor. Besides, the vessels were tortuous, irregular and showed complex branches, and these also could be found around the tumors.
RESULTS AND CONCLUSION: By analyzing the relationship between tumor blood supply and ovarian tumor properties, we found that there was a correlation between the distribution of vascular type in each group and ovarian tumor properties (x2=43.93, υ=2, P < 0.01). The tumor vessels of typeⅠwere mainly found in the benign tumor group, and the tumor vessels of type Ⅱ or type Ⅲ were almost found in the malignant tumor group. In addition, eight cases in the borderline tumor group showed the tumor vessels of type Ⅱ and type Ⅲ. These results suggest that the digital pelvic anatomy model of patients with ovarian tumor was successfully established, and there were differences in vessel types among benign, malignant and borderline tumors.
