Objective To explore the diagnostic effect of CT imaging diagnosis methods on cerebral developmental venous malformations. Methods 20 cases of cerebral developmental venous malformations were selected from September 2010 to September 2015. All patients underwent CT plain scan, CT angiography, CT enhanced volume reconstruction (VR) and MIP CT imaging. Results The selected 20 cases of patients with cerebral developmental venous malformation, CT scan showed 19 cases of patients with intracranial spread in the patchy slightly high density, mainly located in the right frontal lobe, clear boundary, peripheral edema, diagnosis rate was 95%. CT angiography showed the right frontal lobe all patients with multiple abnormal enhanced vessels, a "sea snake head", without peripheral edema, diagnosis rate was 100%. CT enhanced volume reconstruction (VR) visible all right frontal lobe in patients with multiple abnormal vessels, then into the inferior sagittal sinus, diagnosis rate was 100%. CT MIP imaging clearly showed thick veins in all patients into the inferior sagittal sinus, no vascular thrombosis, diagnosis rate was 100%, the diagnostic results and clinical pathology confirmed the results compared to the difference was not statistically significant. The diagnostic rate of CT angiography, VR and MIP CT imaging was higher than that of CT plain scan. Conclusion The diagnosis of cerebral developmental venous anomaly has typical imaging features, so the CT imaging diagnosis methods in cerebral developmental venous anomaly diagnosis has very high application value and is an important inspection method.
