Objective Susceptibility Weighted Imaging Diagnostic Discussion and Analysis of the effect of the application of cerebral hemorrhage. Methods Select the hospital confirmed by pathology study of 78 patients with cerebral hemorrhage, which were simple for 39 cases of cerebral hemorrhage, brain tumor hemorrhage of 39 cases. Patients were used T1WI and T2WI and MR, CE-MR, SWI sequence to be checked. While the differential diagnosis of Statistics and Analysis of simple SWI cerebral hemorrhage and brain tumor hemorrhage. Results After diagnosis found that (1) brain tumor hemorrhage, and six cases of bleeding tumor parenchyma were completely covered and no significant enhancement seen 33 cases of varying degrees of enhancement. Using SWI scan, 33 patients with lesions appear around or partial thickness ranging from low signal and tortuous vascular imaging, six cases of patients with no vascular low signal. (2) simple cerebral hemorrhage in 13 cases no obvious enhancement, 26 cases of mild visible edge enhancement. Using SWI scan showed that 39 patients had no obvious tumor vasculature low signal. Conclusion SWI scan using joint enhanced scan and conventional MR imaging can effectively improve the clinical Simple cerebral hemorrhage and clinical diagnosis and differential rates of brain tumor hemorrhage.
