The conventional MRI features in different benign and malignant vertebral collapse
Main Article Content
Abstract
Purpose: To points out the MRI important features in different benign and malignant vertebral collapse.
Method: Retrospective research bases on the conventional MRI with enhancement of 40 patients who were more than 50 year
old (20 patients with osteoporosis vertebral collapse and 20 patients with malignant collapse) in Ajou university hospital, Suwon, Korea from 01-01-2010 to 01-01-2012. Using Chi-square test to evaluation the significant different in frequency of MRI features of two group.
Result: Lesion with wedge symmetric sharp, posterior wall intact or concave, no or less of paravertebral soft tissue, isointence on T1W, isointence or heterogenous on T2W, no enhance after contrast were favored as benign collapse; lesion with crush asymmetric collapse, big paravertebral mass, include posterior arch lesion, posterior wall convex were favored as malignant collapse.
Conclusion: Conventional MRI enables differentiate between osteoporosis vertebral collapse and malignant collapse.
