  2. CT pulmonary angiogram - Wikipedia

    en.wikipedia.org/wiki/CT_pulmonary_angiogram

    The black areas on either side are the lungs, with around it the chest wall. A CT pulmonary angiogram (CTPA) is a medical diagnostic test that employs computed tomography (CT) angiography to obtain an image of the pulmonary arteries. Its main use is to diagnose pulmonary embolism (PE). [1] It is a preferred choice of imaging in the diagnosis of ...

  3. Computed tomography angiography - Wikipedia

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

    Computed tomography angiography (also called CT angiography or CTA) is a computed tomography technique used for angiography —the visualization of arteries and veins —throughout the human body. Using contrast injected into the blood vessels, images are created to look for blockages, aneurysms (dilations of walls), dissections (tearing of ...

  4. CT scan - Wikipedia

    en.wikipedia.org/wiki/CT_scan

    A computed tomography scan (CT scan; formerly called computed axial tomography scan or 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. [3][4]

  5. 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.

  6. 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. [1]

  7. Coronary CT calcium scan - Wikipedia

    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] These plaques are the cause of most heart ...

  8. Contrast CT - Wikipedia

    en.wikipedia.org/wiki/Contrast_CT

    Volume Rendered Carotid Angiogram. Bolus tracking is a technique to optimize timing of the imaging. A small bolus of radio-opaque contrast media is injected into a patient via a peripheral intravenous cannula.

  9. High-resolution computed tomography - Wikipedia

    en.wikipedia.org/wiki/High-resolution_computed...

    Low-dose high-resolution (1.25 mm) chest CT. HRCT is performed using a conventional CT scanner. However, imaging parameters are chosen so as to maximize spatial resolution: [1] a narrow slice width is used (usually 1–2 mm), a high spatial resolution image reconstruction algorithm is used, field of view is minimized, so as to minimize the size of each pixel, and other scan factors (e.g. focal ...
