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: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
