PURPOSE To implement a three-dimensional subtraction functional CT technique to permit rapid quantitative mapping of regional cerebral blood volume (CBV). METHODS The 3-D functional CT technique was implemented in a rabbit model using normal and ischemic animals. Two spiral data acquisitions were...
PURPOSE To evaluate the clinical applicability of cellulose porous beads (CPBs) as an embolic material for permanent vascular occlusion. METHODS Embolization with CPBs was performed in 16 patients, six with meningioma of the sphenoid wing, two with meningioma of the falx, three with meningioma of...
A three-dimensional fast spin-echo MR technique is proposed for locating contact points on implanted intracerebral multicontact electrode bundles, Coronal or sagittal reformatting shows the entire trajectory of the electrode bundles. The contract points are clearly visible owing to the absence of...
PURPOSE To evaluate the use of magnetization transfer and the apparent enhancement of lesions on contrast-enhanced MR images in patients with multiple sclerosis. METHODS Contrast-enhanced T1-weighted spin-echo MR images obtained in 20 patients with relapsing-remitting multiple sclerosis, with and...
