With this e-module an impression will be given of the state of the art in MR Angio and MR Venography, examining the vessels. The e-module is vendor-independent using the terminology and cases mainly from Siemens, GE, Philips, Canon and Hitachi and could be used as a subject for MRI education on colleges etc. Basic knowledge of MRI is recommended.
MRA – MRV TECHNIQUES
With this e-module an impression will be given of the state of the art in MR Angio and MR Venography, examining the blood vessels. The e-module is vendor-independent using the terminology and cases mainly from Siemens, GE, Philips, Canon and Hitachi and could be used as a subject for MRI education on colleges etc. Basic knowledge of MRI is recommended.
Lessons
Chapter 2 Non CE MRA Methods: TOF / Inflow based – PCA – Flow Quantification
The TOF based and PCA methods are the conventional Non CE ( Contrast-Enhanced) techniques. The TOF MRA related methods show flow related enhancement to identify moving spins. The PCA method shows the blood velocity, also called VENC (Velocity Encoding) and gives a complete suppression of non-moving spins. Those methods are discussed as the parameter settings and applications. Flow Quantification is using basically the PCA method.
Chapter 3 NON CE MRA / MRV METHODS (continued)
The bSSFP, the 3D bSSFP gated with IR prep pulses, the cardiac gated 3D T(F)SE based RF sequences with subtraction, the ASL will be discussed and each can be used as NCE (Non Enhanced) MRA or/and MRV RF sequences.
Chapter 4 NON CE MRA / MRV METHODS: Black – Dark Blood Imaging
Several black blood methods will be discussed like B(D)T(F)SE, the (i)MSDE T(F)SE-ADE RF sequence, DWI used for black blood imaging, SWI (Susceptibility Weighted Imaging) and QSM (Quantitative Susceptibility Mapping).
Chapter 5 MRA MRV Techniques: CE MRA
The Contrast Enhanced MRA’s are discussed, the different methods and parameter fine-tuning.
