title: Intravenous digital subtraction angiography as used in a general hospital: a toy or a tool?
abstract: Although the exact role of digital subtraction angiography (DSA) in diagnostic radiology has not yet been determined, DSA appears to occupy a key position in diagnosing various vascular disorders. The examinations have been performed in a general, nonacademic, nonspecialized hospital for a period of 10 months. No clinical trials or comparative studies have been performed. The number of conventional angiograms has decreased by 43% in comparison to a year ago.
