What is myocardial perfusion imaging Planar?
What is myocardial perfusion imaging Planar?
Planar imaging is an acceptable method for myocardial perfusion imaging. The anatomy of the heart is sufficiently simple that the imaging specialist can comprehend the location and extent of defects from multiple projections without need of computer recon- struction.
What is CT myocardial perfusion?
Dynamic stress myocardial perfusion CT (MPICT) is performed by acquiring a series of CT images after injection of a bolus of contrast medium during pharmacological hyperemia, similar to perfusion imaging technique by MRI or PET.
Is myocardial perfusion scan safe?
What are the risks of a stress myocardial perfusion scan? Risks of the scan may include: The exercise part of the test may lead to rare instances of abnormal heart rhythms, chest pain, or heart attack due to the stress on the heart caused by the exercise. The needle used to put in the IV may cause some pain.
What are the indications and contraindications of myocardial scintigraphy?
Major contraindications to stress myocardial perfusion imaging include: acute coronary syndromes prior to medical stabilization, critical aortic stenosis, known or suspected high-grade left main coronary artery stenosis, uncontrolled arrhythmias, decompensated congestive heart failure, acute aortic dissection, acute …
What is a normal nuclear stress test?
A regular stress test shows the EKG, heartrate and blood pressure while you are walking on a treadmill. A nuclear stress test shows your physician pictures of the blood flow to the heart muscle, in addition to the EKG, heartrate and blood pressure.
Why is CT myocardial perfusion imaging quality assurance important?
CT myocardial perfusion imaging, and close at- tention to quality assurance is needed during image data postprocessing and in the reconstruc- tion and interpretation of attenuation-corrected images. The article reviews the causes and ap-
What is myocardial perfusion test?
Myocardial perfusion is an imaging test. It’s also called a nuclear stress test. It is done to show how well blood flows through the heart muscle. It also shows how well the heart muscle is pumping. For example, after a heart attack, it may be done to find areas of damaged heart muscle.
What is attenuation correction for myocardial perfusion imaging?
Attenuation correction methods have enhanced image quality and improved the sensitivity and specificity of myocardial perfusion imaging by limiting the effect of soft tissue attenuation. Com – puted tomography (CT)-based attenuation maps (ยต maps) obtained with current-generation hybrid single photon emission computed tomography
What are the artifacts most commonly encountered in myocardial perfusion studies?
The artifacts most commonly encountered are related to the characteristics either of the technology or of the patient. Thus, close attention to the details of acquisition protocols, processing tech- niques, and image interpretation is needed to ensure high diagnostic quality in myocardial perfusion studies.
