3D8SWAN in Evaluation of Structural Features of Glioblastome and Metastatic Brain Tumor. 3 Tesla MRI
Т2 Star Weighted Angiography (SWAN) is a variant of high resolution T2- Gradient Echo pulse sequence with high sensitivity to microvenous structures and microhemorrhages of the tissue. On SWAN images tumoral microvessels had the dot-like form, and microhemorrhages (more than 3mm.) looked like spot and micronodules. New MR-sequence SWAN has shown high differential diagnostic potential in demonstration of an abnormal microvascularity and hemorrhages in various tumors of the brain. In our study hemorrhages were typical features in glioblastome (in 92 % of cases), and rare in metastases (in 42 % of cases).
