To obtain information on the characteristics and practices of radiology groups in the United States, the American College of Radiology conducted a group practice survey in 1989; this report presents the main survey findings about the office and hospital practices of such groups. A questionnaire and one follow-up were mailed to all 2,591 radiology groups in the United States. Responses were weighted to reflect all groups. Hospital practices averaged 0.7 diagnostic radiologic procedures (including outpatient procedures) per patient day, with little variation by hospital type. Magnetic resonance (MR) imaging and angioplasty procedures were concentrated in teaching hospitals, but this was not true of other sophisticated procedures such as computed tomography and nuclear medicine. Offices averaged 15,000 diagnostic examinations annually, with less variation than expected according to group size. In both hospitals and offices, more than 90% of technologists were registered. Outsiders (most often, referring physicians and hospitals) had a financial interest in half of all offices. MR imaging and mammography grew faster than any other examinations, but only 44% of hospital practices accepted nonreferred patients for mammography.
为获取有关美国放射学团体的特点及业务情况的信息，美国放射学会于1989年开展了一项团体业务调查；本报告呈现了关于此类团体在诊所及医院业务的主要调查结果。一份调查问卷及一次跟进调查被邮寄给了美国所有2591个放射学团体。对回复进行了加权处理以反映所有团体的情况。医院业务平均每位患者每天进行0.7次诊断性放射学检查（包括门诊检查），不同医院类型之间差异不大。磁共振成像（MR）和血管成形术集中在教学医院，但计算机断层扫描和核医学等其他复杂检查并非如此。诊所平均每年进行15000次诊断性检查，根据团体规模，差异比预期的要小。在医院和诊所中，超过90%的技术人员是注册的。在所有诊所中，有一半的诊所有外部人员（大多数情况下是转诊医生和医院）持有经济利益。磁共振成像和乳房X线摄影检查的增长速度比其他任何检查都要快，但只有44%的医院业务接受未经转诊的患者进行乳房X线摄影检查。
