Biological dose measures promise new view of cardiac imaging risk
By Eric Barnes
The development of biological radiation dose measurement portends a future of far greater accuracy in gauging the damage wrought by ionizing radiation in imaging exams. Two studies, focused on cardiac CT and conventional angiography exams, respectively, offer the potential of maximizing image quality while minimizing the potential radiation risk to the patient.

Lung tumor ablation improved with microwave versus RF technique
By Eric Barnes
Microwave ablation of lung tumors outperforms the more established radiofrequency (RF) ablation technique, according to a new study published in Radiology from the University of Wisconsin. Analysis of gross pathology and CT images found that microwave ablation created larger, more uniform circular zones around ablated regions of normal porcine lungs.
