Pediatric head and neck lesions: assessment of vascularity by MR digital subtraction angiography.
BACKGROUND AND PURPOSE Pediatric head and neck lesions can be difficult to characterize on clinical grounds alone. We investigated the use of dynamic MR digital subtraction angiography as a noninvasive adjunct for the assessment of the vascularity of these abnormalities. METHODS Twelve patients (age range, 2 days to 16 years) with known or suspected vascular abnormalities were studied. Routin...

متن کاملIntravenous angiography using digital video subtraction: x-ray imaging system.
An x-ray imaging system, using digital subtraction techniques, has been developed. The system requires: (1) high output generation equipment; (2) an image intensifier capable of receiving high output exposures, 1 mR (2.58 X 10(-7) C/kg) at the face of the intensifier, without loss of either contrast or resolution; (3) a precision digital video camera; (4) processing computer with sufficient sto...
متن کاملBowhunter's syndrome diagnosed with provocative digital subtraction cerebral angiography.
Bowhunter's syndrome, also known as rotational occlusion of the vertebral artery, involves posterior circulation ischemia resulting from dynamic compromise of the dominant vertebral artery. This case highlights the importance of provocative digital subtraction angiography in making the diagnosis. A 41-year-old man presented for outpatient neurological evaluation for "lightheadedness" of several...
