2. Coronary CT angiography - Wikipedia

   en.wikipedia.org/wiki/Coronary_CT_angiography

   Coronary CT angiography (CTA or CCTA) is the use of computed tomography (CT) angiography to assess the coronary arteries of the heart.The patient receives an intravenous injection of radiocontrast and then the heart is scanned using a high speed CT scanner, allowing physicians to assess the extent of occlusion in the coronary arteries, usually in order to diagnose coronary artery disease.

3. Angiography - Wikipedia

   en.wikipedia.org/wiki/Angiography

   For all structures except the heart, the images are usually taken using a technique called digital subtraction angiography or DSA. Images in this case are usually taken at 2–3 frames per second, which allows the interventional radiologist to evaluate the flow of the blood through a vessel or vessels. This technique "subtracts" the bones and ...

4. Coronary catheterization - Wikipedia

   en.wikipedia.org/wiki/Coronary_catheterization

   Imaging in coronary angiograms is performed via fluoroscopy using X-rays, which pose a potential for increasing the patient's risk of radiation-induced cancer. The risk increases with the exposure time, consisting of 1) time guiding the probe into and out of the heart and 2) time illuminating the contrast agent to perform the angiogram.

   What’s a dangerous heart rate? When we detect heart rates over 90 bpm at rest, that can indicate a sign that something else is at play, such as anemia, dehydration, ...

   Coronary CT angiography (CCTA) is the use of CT angiography to assess the arteries of the heart. The patient receives an intravenous injection of contrast and then the heart is scanned using a high speed CT scanner. With the advances in CT technology, patients are typically able to be scanned without needing medicines by simply holding their ...

7. Magnetic resonance angiography - Wikipedia

   en.wikipedia.org/wiki/Magnetic_resonance_angiography

   Magnetic resonance angiography (MRA) is a group of techniques based on magnetic resonance imaging (MRI) to image blood vessels. Magnetic resonance angiography is used to generate images of arteries (and less commonly veins) in order to evaluate them for stenosis (abnormal narrowing), occlusions, aneurysms (vessel wall dilatations, at risk of rupture) or other abnormalities.

9. Cardiac imaging - Wikipedia

   en.wikipedia.org/wiki/Cardiac_imaging

   A physician may recommend cardiac imaging to support a diagnosis of a heart condition. Medical specialty professional organizations discourage the use of routine cardiac imaging during pre-operative assessment for patients about to undergo low or mid-risk non-cardiac surgery because the procedure carries risks and is unlikely to result in the change of a patient's management.
