At the clinician's disposal is a large armamentarium of tests, including treadmill stress tests, stress echocardiography (ECHO), myocardial perfusion imaging (MPI)—through both single photon emission computed tomography (SPECT) and positron emission tomography (PET)—CT coronary angiography (CTA), and cardiac magnetic resonance imaging (CMR).
Positron emission tomography, also called PET imaging or a PET scan, is a diagnostic examination that involves getting images of the body based on the detection of radiation from the emission of positrons. Positrons are tiny particles emitted from a radioactive substance administered to the patient. Patient Safety Tips Prior to the Exam Please let us know if you have any allergies or adverse ...
What is a PET/CT rest/stress cardiac perfusion scan? A positron emission tomography /computed tomography (PET/CT) rest/stress cardiac perfusion scan is a way to take pictures of blood flow to your heart muscle. Pictures will be taken when you are at rest and after a stress test. This scan is a nuclear medicine exam. It uses a radioactive substance
•CT perfusion software analyzes data and generates color maps and outputs values –Usually a threshold HU below which the software does not include as an area of hypoperfusion to avoid counting prior infarcts/encephalomalacia in calculations. Sample dictation template.

A brain perfusion scan is a type of brain test that shows the amount of blood taken up in certain areas of your brain. This can provide information on how your brain is functioning. There are several different types of brain perfusion scans. Some tests, such as a single photon emission computed tomography (SPECT) or a positron emission (PET ...

A cardiac PET/CT myocardial perfusion scan images blood flow to the heart muscle at rest and stress. It can detect coronary artery disease by demonstrating decreased blood flow, which may benefit from angioplasty or surgery. A follow-up cardiac PET/CT myocardial perfusion scan can be used to assess the effectiveness of treatment.
Purpose To determine the fitting equation that can correct for the underestimation of myocardial blood flow (MBF) measurement by using dynamic CT perfusion (CTP) with dual-source CT (MBFCT), using MBF with oxygen 15–labeled water (15O-water) PET (MBFPET) as a reference, and to determine the accuracy of corrected MBFCT (MBFCT-corrected) compared with MBFPET in a …

What is Positron Emission Tomography – Computed Tomography (PET/CT) Scanning? Positron emission tomography, also called PET imaging or a PET scan, is a type of nuclear medicine imaging. Nuclear medicine uses small amounts of radioactive material called radiotracers. Doctors use nuclear medicine to diagnose, evaluate, and treat various diseases.
Segmental stress and rest perfusion scores can be obtained using the 17- or 20- segment models. Attenuation corrected PET/CT Rb-82 and N-13-ammonia normal limits are provided with QPET. These normal PET/CT databases have separate stress and rest files and combine data from both genders (no differences after attenuation correction).
The new AUC for PET Myocardial Perfusion Imaging addresses several clinical scenarios for nuclear medicine.

Cardiac Perfusion Scan (Nuclear Medicine and PET/CT) Posted: (5 days ago) Cardiac Perfusion Scan (Nuclear Medicine and PET/CT) Cardiac blood flow (cardiac perfusion) can be evaluated by either PET/CT or Nuclear Medicine (using SPECT scanners). A radioactive molecule that has been engineered to mimic the blood flow within the heart is injected into a patient.
Whether CT perfusion can replace xenon or PET in this regard remains to be answered. We have observed similar results between CT perfusion and xenon imaging in patients undergoing an acetazolamide challenge (Fig. 6). A double-blind study is underway to draw more conclusive statistical inferences from these observations.
The use of PET (positron emission tomography) tracers for myocardial perfusion imaging (MPI) began in the 1980s [].Already in those very early years, together with the visual assessment of the uptake pattern, quantitative methods for measuring myocardial blood flow (MBF) were proposed and developed [2,3,4,5].However, due to logistic constraints caused by the high costs of …

18 F-flurpiridaz. 18 F-labeled agents have two major advantages over other PET tracers. First, 18 F has a half-life of 109 minutes, and may be supplied at regional cyclotrons in a similar way as 18 F-FDG. The longer half-life of 18 F also ensures that the radiotracer is present long enough to allow a patient injected at peak treadmill exercise then move to the camera with enough radioactivity ...
