Evaluation of large XXXX with three-dimensional MRI.

@entity1 @entity715 @entity439 @entity438
OBJECTIVE: The purpose of this study was to evaluate large intracranial @entity439 by contrast-enhanced 3D MRI. MATERIALS AND METHODS: Eleven @entity1 , nine @entity1 and two @entity1 , were examined. The @entity439 involved the internal carotid artery in seven @entity1 , the middle cerebral artery in one, the basilar artery in two, and the posterior cerebral artery in one. Contrast-enhanced 3D MR images were obtained using FLASH (fast low angle shot) on a 1.5 T system. We obtained axial images first, then sagittal and coronal images by multiplanar reconstruction. Those images were reviewed for comparison with conventional and MR angiography. RESULTS: We could easily evaluate the true aneurysmal size, the intraaneurysmal constitution (patent lumen and intraluminal thrombus), and the detailed relationship of the @entity439 to the surrounding vascular and neural structures. Except for the cavernous internal carotid artery, we could identify the @entity439 by carefully observing axial, sagittal, and coronal images. In addition, the progression of intraaneurysmal @entity715 and the patency of the parent arterial lumen after the endovascular treatment were well appreciated. CONCLUSION: We consider that 3D MRI appears to be useful for evaluation of the large @entity438 .
