Radiology turf wars and antitrust law
1Medsupplyfinder Inc, Newark, Del., USA.
Abstract:
Nonradiologist health care providers have enjoyed the privilege of film interpretation without the assistance of radiologists. However, encroachment on the radiologist's turf of radiological image interpretation by nonradiologist physicians and radiographer technicians is reminiscent of recent antitrust battles between anesthesiologists and nurse anesthetists. Numerous antitrust issues are relevant to radiology; however, the scope of this article is limited to antitrust issues most relevant to radiology turf battles. Such battles often raise antitrust issues of group boycotts, tying arrangements, and exclusive contracts.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
Positron Emission Tomography
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body being...
Ultrasonography

Radiological Investigation I: X-ray and CT
Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
