AI Technical Summary

Problems solved by technology

This error rate for stress echo testing has resulted in an increase in the number of nuclear perfusion stress tests known to have a high frequency of false positive results
A false positive cardiac stress test may increase the number of costly and unnecessary cardiac catheterization procedures and the associated necessary hospitalization as well as increased patient anxiety, discomfort, and increased medical risk

Description

[0001] related application [0002] This application claims priority to the following U.S. provisional patent applications: 60 / 399,275 filed July 29, 2002, 60 / 421,708 filed October 28, 2002, and 60 / 435,278 filed December 23, 2002, which The contents of are hereby incorporated by reference into this application. technical field [0003] The present invention relates to the field of cardiac diagnostics, and more particularly to stress test cardiac diagnostics using magnetic resonance imaging (MRI) methods. Background technique [0004] The heart is the muscle that continuously pumps blood while delivering life-supporting oxygen and nutrients to the body's major organs and tissues. Because of this, the heart needs a lot of oxygen and nutrients. The heart receives blood from three main coronary arteries. Narrowing or clogging of any of these arteries restricts blood and oxygen flow to the heart, impairs your heart's ability to pump, and can cause permanent damage to your hear...
