The problem of federal regulation of radiologic practice is examined via an in-depth analysis of the Proposed Recommendations for Diagnostic Radiology Facility Quality Assurance Programs as published in the Federal Register by the Commissioner of Food and Drugs. It is shown that the need for such recommendations is not established, that the program proposed by the Commissioner is potentially burdensome for the radiologist, that it does not address the most significant causes of unnecessary patient irradiation, and that the benefits expected to derive from it are, in fact, negligible. This is not to denigrate the value of well-conceived quality assurance efforts, and measures are suggested that might more reasonably be expected to reduce the radiation exposure of the public. The radiologist is urged to 1) conduct his practice in as faultless a manner as possible; and 2) exercise his right to respond to proposals of the federal regulatory agencies.
