  2. Cardiac stress test - Wikipedia

    en.wikipedia.org/wiki/Cardiac_stress_test

    A nuclear stress test uses a gamma camera to image radioisotopes injected into the bloodstream. The best known example is myocardial perfusion imaging. Typically, a radiotracer (Tc-99 sestamibi, Myoview or thallous chloride 201) may be injected during the test. After a suitable waiting period to ensure proper distribution of the radiotracer ...

  3. Myocardial perfusion imaging - Wikipedia

    en.wikipedia.org/wiki/Myocardial_perfusion_imaging

    Myocardial perfusion imaging or scanning (also referred to as MPI or MPS) is a nuclear medicine procedure that illustrates the function of the heart muscle (). [1]It evaluates many heart conditions, such as coronary artery disease (CAD), [2] hypertrophic cardiomyopathy and heart wall motion abnormalities.

  4. Gated SPECT - Wikipedia

    en.wikipedia.org/wiki/Gated_SPECT

    Gated SPECT is a nuclear medicine imaging technique, typically for the heart in myocardial perfusion imagery. [1] An electrocardiogram (ECG) guides the image acquisition, and the resulting set of single-photon emission computed tomography (SPECT) images shows the heart as it contracts over the interval from one R wave to the next.

  5. Technetium-99m - Wikipedia

    en.wikipedia.org/wiki/Technetium-99m

    The underlying principle is, under conditions of stress, diseased myocardium receives less blood flow than normal myocardium. MPI is one of several types of cardiac stress test . As a nuclear stress test , the average radiation exposure is 9.4 mSv, which when compared with a typical 2 view chest X-ray (.1 mSv) is equivalent to 94 Chest X-rays.

    Her doctor also ordered a calcium score test, a type of CT scan of the coronary arteries, to determine the amount of calcium in the arteries, according to the Cleveland Clinic.

  7. Radionuclide angiography - Wikipedia

    en.wikipedia.org/wiki/Radionuclide_angiography

    As the gamma camera images are acquired, the patient's heart beat is used to 'gate' the acquisition. The final result is a series of images of the heart (usually sixteen), one at each stage of the cardiac cycle. [citation needed] Depending on the objectives of the test, the doctor may decide to perform either a resting or a stress MUGA.

  8. Gamma camera - Wikipedia

    en.wikipedia.org/wiki/Gamma_camera

    A gamma camera (γ-camera), also called a scintillation camera or Anger camera, is a device used to image gamma radiation emitting radioisotopes, a technique known as scintigraphy. The applications of scintigraphy include early drug development and nuclear medical imaging to view and analyse images of the human body or the distribution of ...
