Dear AuntMinnie Member,
Dr. David C. Levin of Thomas Jefferson University isn't afraid to pull punches. Known for years as a vocal opponent of physician self-referral, Dr. Levin added teleradiology to his list of peeves in a controversial article in the February issue of the Journal of the American College of Radiology.
Associate editor Kate Madden Yee caught up with Dr. Levin for the next installment in our Leaders in Imaging series, which we're featuring this week in our Imaging Leaders Digital Community. The article explains Dr. Levin's opinions on several issues, including why he thinks radiologists shouldn't be afraid to take night call back from teleradiology firms -- in part because he did it himself for 17 years.

More CT brain perfusion woes
In other news, the touchy topic of radiation overdose in CT brain perfusion studies is getting headlines again, this time after news reports covering events at a hospital in West Virginia.
The hospital reported earlier this month that patients had received radiation doses that were nearly six times higher than guideline recommendations during CT scans performed in 2010. The most disturbing thing about the incident, however, is that it occurred after widely publicized overdoses at hospitals in California and Alabama in 2009.
The incident indicates that manufacturers and healthcare providers can't move quickly enough in adopting scanner enhancements that will enable technologists and radiologists to view the amount of radiation dose a patient receives at the time of the scan -- and not weeks or months later.
