BACKGROUND Although diffusion tensor imaging has been used to monitor Wallerian degeneration, the exact relationship between the evolution of diffusion indices and its underlying pathology, especially in central nervous system, remains largely unknown. Here we aimed to address this question using a cat Wallerian degeneration model of corticospinal tract. (More)
Atypical teratoid/rhabdoid tumor is a highly malignant tumor of the central nervous system, usually occurring in the posterior fossa in infants and young children. Supratentorial example is relatively rare, especially with involvement of the cerebral ventricle system. Herein, we reported 2 cases of atypical teratoid/rhabdoid tumor located in the septum(More)
Isolated cortical vein thrombosis often produces a focal lesion. Because of the rapid development of collateral circulation, increased intracranial pressure has never been reported in a patient with isolated cortical vein thrombosis. The diagnosis of isolated cortical vein thrombosis is based mainly on MRI, catheter digital subtraction angiography, and(More)
PURPOSE To investigate the feasibility of T2W-SPACE technique in early detection of WD, the signal evolutions of degenerated corticospinal tract (CST) on T2W-SPACE, and their underlying pathological changes. MATERIALS AND METHODS The WD model of the CST was established in 23 cats through excision of cortical origins of the tract. Eight cats were scanned(More)
