Ownership/leasing of PET scanners by nonradiologists on the rise

01.03.2010
Just as with computed tomography (CT) and magnetic resonance imaging (MRI), the growth rate among non-radiologists who own or lease positron emission tomography (PET) equipment is also on the rise, contributing significantly to the ongoing issues surrounding self-referral and unnecessary utilization of imaging in the United States, according to a study published in the March issue of the Journal of the American College of Radiology (www.jacr.org). PET is a relatively new technology that produces three-dimensional images of functional processes in the body. It is often used to diagnose certain types of cancer and heart disease.

"One of the well-known factors contributing to rising imaging costs is self-referral among non-radiologist physicians which has been shown to result in unnecessary utilization of imaging," said Rajan Agarwal, MD, MBA, lead author of the study. "This has made imaging one focus of concern as policymakers and third party payers look to cut health care costs," said Agarwal.

Data was collected utilizing the Medicare Part B Physician/Supplier Procedure Summary Master Files for 2002 through 2007. The number of PET scans performed on units owned or leased by various medical specialists, including radiologists was tabulated. While overall imaging growth is in line with or below that of other physician services ©¤

2 percent or less annually since 2006 ©¤ utilization by non-radiologists continues to significantly outpace that of radiologists.

"Results showed that while a large percentage of PET scans in private offices are done by radiologists, the growth rate among non-radiologists was much higher. Between 2002 and 2007 radiologist-owned Medicare PET scans increased by 259 percent, whereas non-radiologist owned or leased scans grew by 737 percent ¡ª a significant difference," said Agarwal.

"At a time when the costs of imaging and the exposure of patients to radiation are coming under intense scrutiny, it is of great concern that many non-radiologist physicians are going outside the scope of their original specialty training and practice experience by acquiring and leasing advanced imaging equipment such as PET scanners," he said.

"Because it has been clearly shown that self-referral leads to higher utilization of imaging this is likely already a significant driver of utilization increases and costs, and it of course also leads to greater exposure of patients to radiation. As was the case with CT and MRI, the PET growth trend among non-radiologists remains high and will bear further watching in future years," said Agarwal.

The March issue of JACR is an important resource for radiology and nuclear medicine professionals as well as students seeking clinical and educational improvement.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
