Imaging

 - Radiation

WASHINGTON, D.C.—Use of a pelvic lead shield draped on a patient and a nonlead cap worn by an operator during coronary angiography reduced physician radiation exposure by more than 75 percent in a study presented Sept. 14 at the Transcatheter Cardiovascular Therapeutics scientific session.

 - PCI

For improved outcomes in patients with chronic total occlusion (CTO), intravascular ultrasound (IVUS)-guided PCI appears to win out over conventional angiography, according to results presented Sept. 14 at the Transcatheter Cardiovascular Therapeutics (TCT) conference.

 - PET/CT Scanner

PET one day may supplant invasive coronary angiography for monitoring heart transplant survivors who are at risk of developing life-threatening cardiac allograft vasculopathy, if preliminary results published online Sept. 2 hold up in larger studies. 

 - heart

Three major quantitative softwares offer cardiologists a comprehensive map of myocardial perfusion and function, but they do not always agree, according to a study in the August issue of the Journal of Nuclear Cardiology.

 - right wrong decision

Hospitals that want to reduce inappropriate PCI rates may want to look beyond the cath lab for opportunities. A study published online Aug. 25 in JAMA Internal Medicine identified diagnostic coronary angiography in asymptomatic patients as a red flag for PCI overuse.
