The rapid growth of cardiac catheterization has raised questions about the availability of less costly, "noninvasive" tests such as cardiac scintigraphy and echocardiography. To assess their availability and rates of use, we surveyed 3,778 non-federal short-term U.S. hospitals in June, 1983. Overall, 2,605 hospitals (69%) offered 201Tl myocardial perfusion scans, 2,580 (68%) 99mTc equilibrium gated blood pool scans, and 2,483 (67%) cardiac shunt scans; 1,679 hospitals (44%) offered M-mode and/or 2-dimensional echocardiography, and 768 (20%) pulsed Doppler echocardiography. Volumes of procedures varied enormously among hospitals capable of performing them. High volumes of both scintigraphy and echocardiography were performed in a small number of hospitals. Larger, voluntary, and teaching hospitals performed higher volumes of both procedures. Despite widespread availability of these "noninvasive" technologies, high volumes of both cardiac scintigraphy and echocardiography procedures are concentrated in a small number of U.S. hospitals.
心导管插入术的迅速发展引发了人们对成本较低的“非侵入性”检查（如心脏闪烁扫描和超声心动图）可用性的质疑。为了评估这些检查的可用性和使用频率，我们于1983年6月对美国3778家非联邦短期医院进行了调查。总体而言，2605家医院（69%）提供铊-201心肌灌注扫描，2580家医院（68%）提供锝-99m平衡门控心血池扫描，2483家医院（67%）提供心脏分流扫描；1679家医院（44%）提供M型和/或二维超声心动图，768家医院（20%）提供脉冲多普勒超声心动图。在有能力开展这些检查的医院中，检查量差异极大。少数医院进行了大量的闪烁扫描和超声心动图检查。较大的、私立的和教学医院开展的这两种检查量更高。尽管这些“非侵入性”技术广泛可用，但大量的心脏闪烁扫描和超声心动图检查集中在美国少数几家医院。
