Comparative Study
Comparison of diffusion tensor image study in association fiber tracts among normal, amnestic mild cognitive impairment, and Alzheimer's patients.
To compare diffusion tensor image (DTI) study in association fiber tracts among normal control (NC), amnestic mild cognitive impairment (aMCI) and Alzheimer's disease (AD) subjects. To assess diagnostic value of DTI in aMCI and differential diagnosis of DTI study between aMCI and AD. ⋯ Based on the results, DTI could be used as a diagnostic method for aMCI with abnormal changes in IFOF and cingulum tract. DTI could also be used for differential diagnosis of aMCI and AD by comparing FA values of the cingulum tract. Abnormal FA values of IFOF, Gcc, and cingulum tract in AD patients may help to elucidate the pathological processes in this disease.

There have been significant advances in the technical aspects of endovascular therapy of cerebral aneurysms. Anterior communicating artery (Acom A) aneurysms were traditionally treated by surgical clipping. Endovascular coiling has the distinct advantage of being minimally invasive and can be performed anytime during the course of subarachnoid hemorrhage (SAH). ⋯ Ruptured Acom A aneurysms are implicated in majority of cases of SAH. Our results support the latest guideline "that endovascular coil occlusion of the aneurysm is appropriate for patients with a ruptured cerebral artery aneurysm that is deemed treatable either by endovascular coiling or by surgical clipping."

We present our findings concerning the laterocavernous sinus (LCS) drainage of cavernous region dural fistulas, focusing our attention on the anatomy of LCS as it may have important implications in the treatment. ⋯ It is very important to diagnose the presence of laterocavernous sinus in dural arteriovenous fistulas during diagnostic angiography. It is believed that the knowledge of the existence of laterocavernous sinus might be relevant for the understanding and treatment of dural fistulas involving the cavernous sinus and its lateral wall.
