Objective to study the row helical CT angiography in the diagnosis of pelvic tumors of department of gynaecology application value. Methods Selection in May 201 to January 201, 112 cases of female pelvic tumor patients of our hospital as the research object, row helical CT angiography in imaging, according to the pathological results will be divided into the malignant tumor group (n=62) and benign tumor group (n=50), and analyze the sensitivity of CT in the diagnosis of pelvic tumors of department of gynaecology, specific degrees and accuracy, and USES the workstation to scan image processing, to observe the CT imaging features of benign and malignant tumor is benign and malignant tumor group CT images showed the tumor boundary, pelvic lymph node enlargement, and according to the perfusion image analysis its blood flow (BF), blood volume (BV), capillary permeability (PS). Results the sensitivity of CT in the diagnosis of pelvic tumors of department of gynaecology is 74.19%, 72.00%, the accuracy is 73.21%. Row helical CT angiography showed a solid lump of department of gynaecology pelvic tumor and cystic and solid cystic mixed, in which the solid mass of soft tissue density, also has a fat density lump, nodules is raised within the sac, fat, hair, calcification, can be seen in the calcified mass point for the performance of films, annular and nodular, not maturity teratoma is more scattered distribution of flake and massive calcification; CT image boundary unclear malignant tumor group 91.90%, 85.48% with pelvic lymph node enlargement and BF (150.26±3.11) ml/min, 100g, BV ml/100g (6.38 1.26 mm), PS (18.16±1.54) ml/min, 100g significantly higher than in benign group (P<0.05). Conclusion Row helical CT angiography for gynecological pelvic tumors is has high diagnostic value, especially malignant tumor, is worth popularizing in clinical application.
