Magnetic resonance imaging detects the flow of contrast-enhanced blood and even allows the quantitative assessment of myocardial perfusion. The clinical application of this method is being held back by the difficulties in image evaluation and the lim

Noninvasive renal blood flow quantitation has been historically difficult, although radionuclide imaging methods for measuring related parameters of renal function such as glomerular filtration rate and effective renal plasma flow have been successfu

Currently, the diagnosis of coronary artery disease is a long, expensive and sometimes invasive process consisting of numerous tests and may include catheterization and hospitalization of patients. The noninvasive nature of a magnetic resonance exami

Cardiovascular magnetic resonance (CMR) has developed multiple techniques that have made it possible to overcome the substantial difficulties in imaging coronary arteries. Tortuous small coronary arteries are imaged in 3D-volume data sets. Cardiac mo

In many cardiac patients, image quality and/or scan efficiency is reduced due to imprecise R-wave ability to trigger the scan due to noise on the electrocardiogram (ECG) caused by the magnetic resonance (MR) environment. We developed a triggering sys

The application of real-time magnetic resonance imaging (MRI) techniques to cardiac imaging is particularly attractive because current MR examinations of left ventricular (LV) function can be prohibitively long and are dependent on electrocardiograph

As outlined in this article, the strength of MR imaging is that it can provide flow, function, and in some cases metabolic data in a single examination, independent of patient body habitus. Future prospects for real-time imaging and in vivo mapping o

Electrocardiograph (ECG) triggered or gated magnetic resonance methods are used in many imaging applications. Therefore, a reliable trigger signal derived from to the R-wave of the ECG is essential, especially in cardiac imaging. However, currently a
