CCTA
Also written as: CCTA — Coronary Computed Tomography Angiography
Non-invasive CT imaging technique used to visualize coronary arteries and detect stenosis.
Full Definition
Coronary Computed Tomography Angiography (CCTA) is a specialized CT scan that uses contrast dye to create detailed images of the coronary arteries. This non-invasive procedure allows clinicians to assess coronary artery disease, detect blockages, and evaluate plaque composition. CCTA has become increasingly important in emergency departments for ruling out acute coronary syndrome in low-to-intermediate risk patients. The technique requires careful patient preparation, including heart rate control and breath-holding instructions.
Usage
Usage note: Always capitalize as CCTA; do not use periods between letters.
