Cardiac Imaging

While cardiac ultrasound is the widely used imaging modality for heart assessments, computed tomography (CT), magnetic resonance imaging (MRI) and nuclear imaging are also used and are often complimentary, each offering specific details about the heart other modalities cannot. For this reason the clinical question being asked often determines the imaging test that will be used.

Ultralow-dose CT shows potential to substitute for standard coronary calcium imaging

Compared side-by-side with standard cardiac CT for calcium scoring, ultralow-dose CT shows good sensitivity, specificity and overall accuracy despite its markedly lower radiation dose. In fact, it’s unlikely to miss coronary calcification in patients with at least moderate calcium load and could offer a sensible alternative for some patients sent for coronary CT angiography.
