In patients with atrial fibrillation (AF) and a positive D-dimer result, chest computed tomography angiography (CTA) may be necessary to rule out pulmonary embolus.

Three-dimensional imaging technologies (CT scan or MRI) are often helpful to evaluate atrial anatomy if AF ablation is planned. Imaging data can be processed to create anatomic maps of the left atrium and pulmonary veins.
