Abstract: Objective: To study under the act and act on the brain MRI findings of central nervous cell tumor. Methods: From August 2010 to June 2015, 39 patients with central nervous cell tumor of our hospital, using GE Highspeed CT/I, for all patients with CT scan, and the use of GE signa Twinspeed 1.5 T superconducting MRI scanner, an MRI scan on all of the patients of 39 patients with central nervous cell tumor were detected in the ventricle under the act and act on tumor location, size, shape; And the performance of the contrast CT scan and MRI. Results: In 39 patients with central nervous cell tumor, 13 cases located in the right lateral ventricle, 9 cases located in the left lateral ventricle, 11 cases of patients with bilateral lateral ventricle is the tumor, the other 6 cases with bilateral lateral ventricle and the third ventricle tumor. 39 patients with tumor size for an average of 52 mm; 36 cases showed irregular, lobulated 3 cases of tumor boundary vague. Part has different degree of tumor calcification phenomenon. Conclusion: The imaging findings of central nervous cell tumor site and was typical characteristic, by CT scans and MRI scanning, can effective detection of the central nervous cell tumor, and MRI imaging examination, can effectively improve the diagnostic accuracy rate of the central nervous cell tumor, the inspection result is superior to CT examination.
