CT Angiography (CTA)

CT Angiography (CTA)

CT Angiography (CTA) is a specialized CT examination designed to obtain high resolution images of arterial vessels throughout the body.  With computer software, manipulation of acquired CT data allows the construction of detailed 2D and 3D images that can be interpreted by a radiologist.  CTA is an alternative to conventional catheter angiography, which is more invasive and is normally performed in an inpatient hospital setting.  CT angiography can be used to diagnose pulmonary embolism, coronary artery pathology, vascular anomalies, and aneurysms / vascular pathology throughout the body from the head to the lower extremities.

Coronary CT angiography (CCTA) is a non-invasive test that allows visualization and detection of narrowed segments or complete blockages of the coronary arteries.  At Litton & Giddings Radiological Associates, PC (LGRA), the utilization of 64-slice CT scanners designed for cardiac imaging allows visualization of the entire coronary artery tree with high resolution and minimization of patient radiation.  64-slice CT technology can provide assessment of the coronary arteries in approximately 5 seconds, obtaining more information than a conventional (more invasive) cardiac catheterization.  In addition to coronary CTA, LGRA offers comprehensive cardiac imaging capabilities including coronary calcium scoring with CT, cardiac MRI, MRA, vascular ultrasound with Doppler technology, and nuclear cardiology.
