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.
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.

Imaging of the cardiovascular system is usually performed with cardiac gating using an adaptation of conventional ECG techniques. [19] Cine sequences of the heart are acquired using balanced steady state free precession (bSSFP) which has good temporal resolution and intrinsic image contrast. T1-weighted sequences are used to visualize anatomy ...
It contributes to heart failure being a progressive disease, one in which the heart continually gets worse. The device is placed in the heart using a catheter-based system. A thin metal wire made of a special medical-grade alloy tightens up this valve, putting a little ring around it from the outside, which improves the function of the mitral ...
Recently, there is some evidence VSARR has superior survival rates at 10 and 15 years along with reduced early mortality. [11] Moreover, while there is a decreased reoperation rate in the first 5 years seen with the Bentall procedure, the need for reoperation after Bentall and VSARR are then comparable thereafter.
Radionuclide angiography is an area of nuclear medicine which specialises in imaging to show the functionality of the right and left ventricles of the heart, thus allowing informed diagnostic intervention in heart failure. It involves use of a radiopharmaceutical, injected into a patient, and a gamma camera for acquisition.
Social Security is the U.S. government’s biggest program; as of June 30, 2024, about 67.9 million people, or one in five Americans, collected Social Security benefits.This year, we’re seeing a ...
Diabetic cardiomyopathy is a disorder of the heart muscle in people with diabetes.It can lead to inability of the heart to circulate blood through the body effectively, a state known as heart failure(HF), [2] with accumulation of fluid in the lungs (pulmonary edema) or legs (peripheral edema).
