Cardiac MRI at 3 Tesla - Challenges and Technical Solutions
Introduction Cardiac magnetic resonance (CMR) has rapidly become the imaging method of choice for the diagnosis of cardiovascular disease, and its clinical indications have expanded greatly in the last decade [1]. Although the majority of CMR examinations is still performed at a field strength of 1.5 Tesla, the growing availability of 3 Tesla scanners has resulted in an increasing number of CMR...
متن کامل3-D RF Coil Design Considerations for MRI
High-frequency coils are widely used in medical applications, such as Magnetic Resonance Imaging (MRI) systems. A typical medical MRI includes a local radio frequency transmit/receive coil. This coil is designed for maximum energy transfer or wave transfer through magnetic resonance. Mutual inductance is a dynamic parameter that determines the energy quantity to be transferred wirelessly by ele...
متن کاملReal-time cardiac MRI at 3 tesla.
Real-time cardiac and coronary MRI at 1.5T is relatively "signal starved" and the 3T platform is attractive for its immediate factor of two increase in magnetization. Cardiac imaging at 3T, however, is both subtly and significantly different from imaging at 1.5T because of increased susceptibility artifacts, differences in tissue relaxation, and RF homogeneity issues. New RF excitation and puls...
متن کاملHigh-quality breast MRI.
Breast magnetic resonance imaging (MRI) demands the competing factors of high spatial resolution, good temporal resolution, high signal-to-noise ratios, and complete bilateral breast coverage. Achieving these competing factors requires modern MRI equipment with high magnetic field strength and homogeneity, high maximum gradient strength with short rise times, dedicated multichannel bilateral br...
متن کاملTransmit B1+ field inhomogeneity and T1 estimation errors in breast DCE-MRI at 3 tesla.
PURPOSE To quantify B1+ variation across the breasts and to evaluate the accuracy of precontrast T1 estimation with and without B1+ variation in breast MRI patients at 3 Tesla (T). MATERIALS AND METHODS B1+ and variable flip angle (VFA) T1 mapping were included in our dynamic contrast-enhanced (DCE) breast imaging protocol to study a total of 25 patients on a 3.0T GE MR 750 system. We compute...
