[Acute brain infarction clearly demonstrated by using the three-dimensional stereotactic surface projections (3D-SSP) of 99mTc-HMPAO SPECT].

We report a 66-year-old ambidextrous man who suddenly developed aphasia seven days after coronary artery bypass grafting surgery. CT scan performed 30 minutes after onset failed to depict acute ischemic lesion. MR imaging could not be performed because of intrathoracic wires.

[Multiple brain infarctions in a young patient with Buerger's disease. A case report of cerebral thromboangiitis obliterans].

We report a 46-year-old woman with Buerger's disease who presented vascular dementia. In her early thirties, she began to feel cold sensation and pain in the lower extremities and later developed Raynaud's phenomenon in the upper extremities. The diagnosis of Buerger's disease was established on the basis of angiographic findings which showed the obstruction of peripheral vessels in both anterior tibial arteries.

Imaging of distal internal carotid artery by ultrasonography with a 3.5-MHz convex probe.

Background And Purpose: Conventionally, carotid ultrasonography has been performed with a 7.5-MHz linear probe to evaluate the extracranial internal carotid artery (ICA). However, usually only the carotid bulb or proximal portion of the ICA can be evaluated.
