There are patients who have low signal lesion with T2* weighted image along on the surface of brain which is associated with local neurological symptoms without cortical multiple microhemorrhages typical for CAA. Such cases could be diagnosed as both CAA and isolated cerebral cortical venous thrombosis (ICVT). The purpose of this study is to evaluate the differences in the pathogenesis of ICVT and CAA, focusing on the degree of cerebral amyloid deposition using amyloid PET.

1) T2* weighted image demonstrates linear low intensities along surface of the brain.
2) Neurological symptoms (including transient) correlate with the cortical linear lesions in T2* weighted image.
3) Two or more physicians diagnose that multiple cortical micro bleeds in the cerebrum or cerebellum are not conspicuous on T2* weighted image.
4) The score of Mini Mental State Examination is not matter.
5) Age and gender do not matter.
6) The written informed consent is obtained from the patient or representative.
1. Highly suspected with CAA
2. Diagnosed as Alzheimer's disease
3. Contraindication for MRI (pacemaker, brain clip etc)
4. Inappropriate cases to participate in this study judged by the physicians.

There are patients with linear low signal lesions along the brain surface on MRI T2* weighted image accompanied with local neurologic symptoms associated with them. In these patients, cerebral or cerebellar cortical microbleeds which are typical in patients with cerebral amyloid angiopathy (CAA) is inconspicuous. Such cases can be ether CAA with amyloid spell or isolated cortical venous thrombosis (ICVT). In this study, amyloid PET imaging (amyloid PET) would be performed on such cases to evaluate the status of amyloid beta protein deposition. The purpose of this study is to address the differences in the pathogenesis of ICVT and CAA, focusing on the degree of cerebral amyloid deposition. Based on the anatomical information of MRI image, the SUVR (SUV value on amyloid PET of cerebral cortex is divided by the one of cerebellum) was calculated. In addition, we would obtain control data from patients with Alzheimer's disease and healthy elderly people used in previous research. SUVR were compared among three groups (20 patients with Alzheimer's disease, 20 healthy controls and 10 patients in this study).
