Your doctor may recommend coronary angiography if you have:
Coronary angiography also might be done on an emergency basis, such as during a heart attack. If angiography shows blockages in your coronary arteries, your doctor may do a procedure called angioplasty (AN-jee-oh-plas-tee). This procedure can open blocked heart arteries and prevent further heart damage.
Coronary angiography also can help your doctor plan treatment after you’ve had a heart attack, especially if you have major heart damage or if you’re still having chest pain.
Clinical trials are research studies that explore whether a medical strategy, treatment, or device is safe and effective for humans. To find clinical trials that are currently underway for Coronary Angiography, visit www.clinicaltrials.gov.

Next-generation CT scanner provides better images with minimal radiation
A new computed tomography (CT) scanner substantially reduces potentially harmful radiation while still improving overall image quality. National Institutes of Health researchers, along with engineers at Toshiba Medical Systems, worked on the scanner. An analysis of data on 107 patients undergoing heart scans found that radiation exposure was reduced by as much as 95 percent compared to the range of current machines, while the resulting images showed less blurriness, reduced graininess, and greater visibility of fine details.
