Purpose Of Review:
To briefly review the field of radionuclide stress imaging, including recent technologic advances and clinical applications.
Recent Findings:
ECG gating and attenuation correction help increase specificity and accuracy of myocardial single-photon emission computed tomography (SPECT) imaging. Furthermore, advances in camera hardware and software enable more rapid image acquisition and/or radiation dose reduction. Position emission tomography (PET) and hybrid imaging with computer tomography (CT) are emerging technologies which provide improved image resolution and complementary anatomical data. Nuclear cardiology also demonstrates a wide variety of prognostic applications for a diverse group of patient subgroups. More judicious use of SPECT technology using application of the recently updated appropriateness criteria is encouraged.
Summary:
Radionuclide stress imaging provides essential clinical information and has clear impact on patient assessment and management.

01:26Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...
