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.
尽管数字减影血管造影（DSA）在诊断放射学中的确切作用尚未确定，但DSA在诊断各种血管疾病方面似乎占据关键地位。这些检查在一家普通的、非学术性的、非专科医院进行了10个月。未进行临床试验或对比研究。与一年前相比，传统血管造影的数量减少了43%。
