Cardiac Imaging

Doses over 7.5 mSv of radiation from cardiac CTA cause cellular damage.

Imaging with electron beam tomography or CT helps determine plaque build-up in coronary artery calcification among asymptomatic patients.

Patients who undergo coronary CT angiography receive lower radiation doses and are more pleased with the experience than with MPI.

Coronary CT angiography detects links between arterial plaque, diabetes, blood pressure, and cholesterol levels.

Case History: 60-year-old female with shortness of breath worsening with exertion and fatigue.

A CT protocol with lower radiation and contrast dose for aortic assessment provides acceptable diagnostic imaging.

Radiation exposure during angiography might be decreased if radiologists can view the images on wide screens.
