To determine current clinical practice in the radiological diagnosis of acute pulmonary embolism and assess the use of spiral volumetric computed tomography.
A survey of 327 acute hospitals including cardiothoracic and orthopaedic tertiary referral centres was undertaken to assess current utilization of lung scintigraphy, spiral computed tomography and pulmonary angiography in the investigation of suspected pulmonary embolism. Responses were received from 215/327 (66%) centres.
Lung scintigraphy was provided by 208 hospitals (144 on-site and 64 off-site). Spiral CT services were provided by 111 (52%) hospitals (on- or off-site), 142 (66%) units had access to angiographic facilities. Sixty-three centres out of 215 (29%) offered both on-site lung scintigraphy and spiral CT while only 41/215 (19%) hospitals were able to undertake all three tests on-site. On average, 501 perfusion (Q) or ventilation-perfusion (V/Q) scintigrams were performed per hospital per year with 26 spiral CT studies and just 4.6 pulmonary angiograms.
These data suggest that lung scintigraphy is frequently the only imaging test in patients other than chest radiography, despite the large number of indeterminate results reported in most series.
确定急性肺栓塞放射诊断的当前临床实践，并评估螺旋容积计算机断层扫描的使用情况。
对327家急症医院进行了调查，其中包括心胸和骨科三级转诊中心，以评估目前在疑似肺栓塞检查中肺闪烁扫描、螺旋计算机断层扫描和肺血管造影的使用情况。共收到215/327（66%）个中心的回复。
208家医院提供肺闪烁扫描（144家现场提供，64家非现场提供）。111家（52%）医院提供螺旋CT服务（现场或非现场），142家（66%）单位可使用血管造影设备。215个中心中有63个（29%）同时提供现场肺闪烁扫描和螺旋CT，而只有41/215（19%）家医院能够在现场进行所有三项检查。每家医院每年平均进行501次灌注（Q）或通气-灌注（V/Q）闪烁扫描，26次螺旋CT检查，仅4.6次肺血管造影。
这些数据表明，尽管大多数系列报道的不确定结果数量众多，但除胸部X线检查外，肺闪烁扫描常常是患者唯一的影像学检查。
