By Eric Barnes
Depending on where one stands in the radiation hormesis debate, a new study on CT lung screening may or may not be of concern. Still, new estimates of a 5% increase in excess lung cancers among frequently screened smokers are noteworthy in anyone's book, and may even prompt some radiologists to fine-tune their protocols.

Hippocampal volume on MRI indicates time to Alzheimer's disease
By Tracie L. Thompson
When patients are diagnosed with mild cognitive impairment, it remains unclear if or when they might progress to Alzheimer's disease. But a new study presented Thursday at the American Society of Neuroradiology (ASNR) meeting suggests the transition is inevitable, and that hippocampal volume on MRI roughly predicts how soon it will happen.

Contrast-enhanced CT finds myocardial infarction
By Eric Barnes
Several new studies are reporting that contrast-enhanced CT can readily demonstrate myocardial infarction (MI) as foci of reduced attenuation compared with normal myocardium. The studies hint at a predictive role for CT in assessing a patient's prognosis after a cardiac event.

MRS predicts severity of brain injury in abused infants
By Tracie L. Thompson
After a shaken baby recovers from the immediate trauma that prompted medical intervention, it may be difficult to distinguish those who suffered more significant and long-lasting brain injury. Presenters at the American Society of Neuroradiology meeting in Seattle said an MR spectroscopy (MRS) exam in the acute phase may actually distinguish those children quite accurately.

Focus of TLE seizure clarified with MR plus diffusion tensor imaging
By Shalmali Pal
Diffusion tensor imaging (DTI) can bolster brain MR when zeroing in on seizure sites in temporal lobe epilepsy (TLE), according to a presentation Tuesday at the American Society of Neuroradiology (ASNR) meeting in Seattle. This information could then aid in pre-surgical planning, said the authors from Drexel University in Philadelphia and the University of Illinois in Peoria.

Authors offer remedies for artifacts on MDCT coronary angio
By Tracie L. Thompson
Multidetector CT offers many advantages over single-slice scanning, especially in noninvasive CT angiography. But artifacts can still mar MDCT images of the coronary arteries, especially if your scanner has only four detector rows.
