Computed Tomography Angiography

Northwestern Medicine uses the dual-source 64-slice computed tomography angiography (CTA), an advanced, non-invasive diagnostic tool that visualizes the myocardium (heart), coronary circulation and aorta. This revolutionary technology dramatically alters the way cardiac and vascular diseases such as coronary artery disease (CAD), dissections and aneurysms of the aorta and atrial fibrillation are diagnosed, evaluated and treated.

The dual-source 64-slice CTA divides the heart, aorta and lungs into thousands of imaginary slices producing near perfect, three-dimensional, high-quality diagnostic images of the heart, aorta, lungs and coronary circulation.

Offered through the Northwestern Medicine Department of Radiology, the entire test takes between 30 to 90 minutes, but the image acquisition takes approximately 10 seconds. Dual-source 64-slice CTA offers physicians the ability to quickly and non-invasively diagnose cardiac and vascular disease.
