The treatment of large, high-flow cerebral arteriovenous malformations is one of the most difficult operations which neurosurgeons encounter because of the complex surgery and the post-operative effects on the brain. We have evaluated 10 patients with large, high-flow AVMs who underwent surgical resection. Patients were investigated with contrast-enhanced(More)
A rare case of hemorrhagic infarction associated with carotid-cavernous fistula is reported. The patient was a 74-year-old female. CT scan showed hemorrhagic infarction of the left superior temporal gyrus, irregular vascular enhancement of the bilateral front-temporal lobe, and dilatation of the cavernous sinus. Left carotid angiogram revealed a high-flow(More)
A patient with subacute bacterial endocarditis and a peripheral mycotic aneurysm is presented. We used a combined multi-slice surface anatomy scanning (SAS) and contrast-enhanced MR angiography image to determine the exact location of the small lesion by applying a skin marker on the scalp and visualizing the relationship of the marker to the brain surface(More)
Helical scanning CT (HES-CT) was applied to multiplanar reconstruction (MPR) and 3-D imaging for the diagnosis of 65 patients with orbital lesions. We employed the the Toshiba TCT-900S, a fourth-generation high-speed CT scanner equipped with a slip-ring system. In HES-CT, scanning was performed with continuous rotation of the X-ray tube for 30 s, while the(More)
Image quality of dynamic single photon emission computed tomography (SPECT) using a rotating gamma camera is dependent on the time activity variation of the tracer such as accumulation and excretion in the object's organ. Especially at the early time after injection of radionuclide, artifacts may occur strongly in the SPECT images. Simulated and(More)
SUMMARY Embolization using IDC was carried out for 33 aneurysm cases in the last 3 years. The indication for the embolization was that the direct surgery was considered to be difficult, because of 1) technically impossible to do clipping, 2) aneurysm of the posterior fossa, 3) reject of patients. Regarding the location of aneurysm, 27 cases were seen in the(More)
