Turf wars in radiology: other causes of overutilization and what can be done about it

Abstract:
The overutilization of noninvasive diagnostic imaging (NDI) is a complex problem with many other aspects aside from self-referral. This article discusses (1) other causes of overutilization, (2) the rationales used by nonradiologist physicians to justify self-referring their patients for NDI, (3) the extent of self-referral by radiologists (called "autoreferral" by some), and (4) steps that could be taken to curb the overutilization of NDI in the United States. It is important for radiologists to be familiar with these issues and to support efforts to control overutilization.

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...

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...
