A non-contrast time-resolved MR imaging technique promises to help interventional cardiologists treat peripheral vascular disease.

PET imaging of asymptomatic individuals revealed coronary vasculardysfunction as a functional precursor of coronary artery disease,according to research presented during this week's SNM conference inNew Orleans.

Preliminary clinical findings indicate that when used with PETtechnology, Lantheus Medical’s PET Myocardial Perfusion Imaging Tracerdemonstrates a favorable radiation dosimetry profile and is generallywell-tolerated, according to phase I data presented during the Societyof Nuclear Medicine (SNM) conference in New Orleans.

Siemens Healthcare highlighted its work-in-progress IQ-SPECT as thecompany’s newest Symbia application, which enables a comprehensivecardiac evaluation including perfusion, attenuation correction andcalcium scoring in just five minutes, this week at the 2008 Society ofNuclear Medicine (SNM) meeting in New Orleans.

Positron has acquired Dose Shield, a subsidiary of NukeMed, and has formed a new subsidiary, Positron Pharmaceuticals.

Ziosoft, a provider of advanced visualization and analysis software formedical imaging, is partnering with Johns Hopkins University inBaltimore, to explore innovative applications for cardiac CT and MRimaging.

Researchers in France found that 64-slice CT coronary angiographyperforms as well as invasive angiography to detect significant coronarylesions in children who have undergone the arterial switch procedurefor transposition of the great arteries. They also found that CTprovides information on the underlying mechanism of coronary luminalnarrowing.

Calcium coverage scoring, which identifies the amount anddistribution of calcified plaque in the coronary arteries, may betterpredict a person's risk of heart attack than calcium burden alone,according to a multicenter study published in the June issue of Radiology.
