A survey of UK radiologists in 360 acute hospitals was undertaken to assess the current use of pulmonary angiography and radionuclide lung scanning in the investigation of suspected pulmonary thromboembolism (PTE). Replies were received from 340 (94%) hospitals, of which 48 (out of 50) were teaching hospitals or centres which perform cardiothoracic surgery. Lung scintigraphy was provided by 200 (59%) hospitals and angiography by 120 (35%), with 99 (29%) providing both. Twenty-two hospitals which could undertake angiography had not performed more than one angiogram for suspected PTE in the preceding 3 years. Average numbers of lung scans performed in each hospital were 21.8 per month, in contrast with an average of 4.1 angiograms (including digital subtraction angiography) per year performed for suspected PTE over the previous 3 years. The total number of V/Q lung scans performed for the diagnosis of PTE per year was approximately 47,000 compared with 490 pulmonary angiograms.
对英国360家急症医院的放射科医生进行了一项调查，以评估目前在疑似肺血栓栓塞症（PTE）的调查中肺血管造影和放射性核素肺扫描的使用情况。收到了340家（94%）医院的回复，其中48家（共50家）是进行心胸外科手术的教学医院或中心。200家（59%）医院提供肺闪烁扫描，120家（35%）提供血管造影，99家（29%）两者都提供。22家能够进行血管造影的医院在过去3年中针对疑似PTE进行的血管造影不超过1例。每家医院每月进行的肺扫描平均数量为21.8次，相比之下，过去3年中针对疑似PTE每年进行的血管造影（包括数字减影血管造影）平均为4.1例。每年用于诊断PTE的V/Q肺扫描总数约为47,000次，而肺血管造影为490例。
