Cardiac MRI
Introduction Cardiac MR imaging allows for the examination of anatomy, function, and metabolism and its clinical use is steadily increasing. It poses unique challenges to the imaging protocols as it requires high spatial resolution over a larger volume in the presence of cardiac and breathing motion. This overview of cardiac MRI discusses methods to reduce motion artifacts and various clinical ...
متن کاملCardiac MRI at 7T
In the brain, results have been shown at 7T that are not achievable at lower field strengths. Cardiac imaging at 7T offers similar headline benefits to those images of the brain. More field strength gives more SNR, added to which more field strength increases the T1 and hence increases the effect of contrast agents. This simple idea is appealing in a grant application, but in reality 7T has som...
متن کاملFetal cardiac MRI
Background MRI has been confirmed as an important tool for fetal central nervous system and other diseases. MRI has also emerged as a powerful approach to imaging heart diseases in infants. But fetus with heart diseases diagnosed by MRI has relative rarely been reported. Now most doctors agree that fetal cardiac MRI can provide some additional information when the patient was with some special ...
متن کاملSensitivity encoded cardiac MRI.
Imaging speed is a key factor in most cardiovascular applications of magnetic resonance imaging. Recently, simultaneous signal acquisition with multiple coils has received increasing attention as a means of enhancing scan speed in MRI. Based on this approach, the sensitivity encoding technique SENSE enables substantial scan time reduction by exploiting the inherent spatial encoding effect of re...
متن کاملAxial Cardiac MRI Registration
This paper focuses on finding techniques that can be used in cardiac magnetic resonance images semiautomatic registration in a simple and fast way. The suggested technique depends on using parts of one image selected by the user to be matched with another image of the same patient in order to find control points or correspondences between those two images. The experiment focuses on three techni...
