    Apical four chamber ultrasound view of heart. Transthoracic echocardiography (TTE) uses ultrasonic waves for continuous heart chamber and blood movement visualization. It is the most commonly used imaging tool for diagnosing heart problems, as it allows non-invasive visualization of the heart and the blood flow through the heart, using a technique known as Doppler.

  3. 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.

  4. CT scan - Wikipedia

    en.wikipedia.org/wiki/CT_scan

    A computed tomography scan (CT scan), formerly called computed axial tomography scan (CAT scan), is a medical imaging technique used to obtain detailed internal images of the body. [2] The personnel that perform CT scans are called radiographers or radiology technologists.

  6. Electron beam computed tomography - Wikipedia

    en.wikipedia.org/wiki/Electron_beam_computed...

    Electron beam computed tomography (EBCT) is a fifth generation computed tomography (CT) scanner in which the X-ray tube is not mechanically spun in order to rotate the source of X-ray photons. This different design was explicitly developed to better image heart structures that never stop moving, performing a complete cycle of movement with each ...

    en.wikipedia.org/wiki/Coronary_CT_calcium_scan

    A coronary CT calcium scan is a computed tomography (CT) scan of the heart for the assessment of severity of coronary artery disease.Specifically, it looks for calcium deposits in atherosclerotic plaques in the coronary arteries that can narrow arteries and increase the risk of heart attack. [1]

    en.wikipedia.org/wiki/Computed_tomography...

    Volume rendered CT scan of abdominal and pelvic blood vessels. CT angiography is a contrast CT where images are taken with a certain delay after injection of radiocontrast material. The contrast material is radiodense causing it to light up brightly within the blood vessels of interest. In order for the CT scanner to be able to scan the correct ...

  9. Cone-beam spiral computed tomography - Wikipedia

    en.wikipedia.org/wiki/Cone-beam_spiral_computed...

    Cone-beam spiral computed tomography (CT) is a medical imaging technology that has impacted healthcare since its development in the early 1990s. [1] [2] This technology offers advancements over traditional fan-beam CT, including faster scanning speed, higher image quality, and the ability to generate true three-dimensional volumes, even with contrast-enhancement.
