TMJ imaging benefits from digital tomo technique
By Brian Casey
Japanese researchers have produced good results using a digital tomosynthesis technique for general radiography studies of the temporomandibular joint (TMJ). As part of its research, the group also developed a new reconstruction algorithm for digital tomo studies that they say reduces image artifacts in the 3D volumes generated by the digital tomo system they used.

Multicenter trial supports CTPA versus V/Q for PE
By Eric Barnes
A study in the December 19 Journal of the American Medical Association confirms that CT pulmonary angiography (CTPA) is a reliable alternative to ventilation-perfusion (V/Q) scans for ruling out pulmonary embolism (PE). CT doesn't miss clinically significant blood clots in the lungs, and can also help reveal other potential causes of the patients' symptoms, the authors report.

CTA predicts mortality, shows variable risk per vessel
By Eric Barnes
Two major cautionary notes attached to coronary CT angiography (CTA) are the scarcity of literature proving a benefit in patients at risk of coronary artery disease (CAD) and its high radiation dose. Researchers at UCLA-Harbor Medical Center in Torrance, CA, believe they've gone a long way toward conquering both limitations with a low-dose 64-slice CT exam protocol and participation in several new studies suggesting a high prognostic value for CTA studies.
