The study of characteristic imaging of non-traumatic cerebral parenchymal hemorhage on MRI
Main Article Content
Abstract
SUMMARY
Objective: This study aims to describe the characteristic and find out the causes of non-traumatic cerebral parenchymal hemorhage on MRI.
Materials and methods: Across descriptive study was underwent on 45 patients suffering from cerebral parenchymal hemorhage in BachMai hospital, from January to Sseptember, 2010.
Results: Super-acute stade: The hematoma is isointense on T1, central hyperintense and peripheric hypointense on T2, Flair, T2* (5/5 cases). Acute stade: isointense on T1; hypointense in the centre, hyperintense in peripheric on T2, Flair (2/2 cases). Early subacute stade: homogeneous hyperintense on T1W (6/8 cases). Later subacute stade: homogeneous hyperintense on T1W (84.6%), peripheric hypointese on T2W (88.5%). Chronic stade: isointense
on T1, Central hyperintense on T2, Flair, T2* (2/2 cases). Hypertension is the most common causes (48.5%) and leads to central noyal hematoma. Meanwhile lobular hematoma is due to
vascular malformation (35.3%). The hyperintense is more frequently in over 50 years old (73.1%) and vascular malformation is seen in the under 50 years old (47%).
Conclusion: MRI is effective method to evaluate the characteristic of cerebral parenchymal hematoma and has important role in searching the causes.
