Abstract

Objective To investigate the clinical diagnosis value of CT and MRI in arterio venous alformation (AVM) of brain. Methods Retrospectively analyze the clinical and CT &MRI data of 32 patients with AVM in our hospital from February 2014 to February 2016. Results Through the diagnose of CT and MRI, there are 3 patients in Spetzler&Martin class I, 9 patients in class II, 19 patients in class III and 2 patients in class IV. 26 cases of AVM occur in supratentorial craniocerebral, 6 cases exist in infratentorial, the size of tumor nests range from 1.1cm to 9.3cm, average (3.6±0.9)cm, 6 cases are large (>5cm), 18 cases are medium-sized (2.5cm-5.0cm) and 8 cases are small(<2.5cm). Conclusion CT and MRI can clearly show the direct signs and indirect signs of AVM with a high diagnostic rate, which has great clinical application value.
