Advanced Cardiovascular Applications


Inhance Inhance
   TRICKS-XV TRICKS-XV

The new GE suite of NCE MRA applications is robust, fast and easy to use. Inhance Inflow IR, Inhance 3D Velocity and Inhance 2D Inflow sequences deliver consistent, reproducible MRA data even in difficult-to-scan anatomies, resulting in fewer rescans and more confident differential diagnoses. 		 
TRICKS XV uses an innovative time resolved k-space filling, sophisticated data reconstruction and parallel acceleration techniques to allow increased temporal resolution without sacrificing SNR or spatial resolution. TRICKS eliminates the need for test injections of contrast or triggering. The acquired data includes multiphase images of the entire arterial and venous filling, providing high-resolution information about flow dynamics and allowing reliable arterial-venous separation.
   
MR Echo MR Echo 2D FIESTA 2D FIESTA

MR Echo provides an environment and tools for generating high-definition cardiac exams in real time without the need for respiratory or ECG gating. MR Echo employs accelerated FIESTA, time course or myocardial delayed enhancement techniques to perform cardiac exam in real time, in a non-gated or VCG-gated modi. The intuitive interface enables the user to quickly scan the heart in any orientation and to save real time images.
The FIESTA 2D pulse sequence provides excellent blood to myocardium contrast optimized for cardiac imaging. The short TR/TE capability of this sequence allows acquisition of high quality cardiac images that are less sensitive to turbulent blood flow.
     
3D FIESTA 3D FIESTA   3D FIESTA-C 3D FIESTA-C

The FIESTA 3D pulse sequence provides excellent high-resolution images of fluid filled structures in very rapid acquisition times. FIESTA employs ultra-short TR's and TE's for very fast scan times with outstanding image contrast. 		 
This phase-cycled FIESTA technique reduces sensitivity to changes in magnetic susceptibility that may be encountered when imaging e.g. posterior fossa and anatomies near air-tissue boundaries. Extremely short TR helps generate high-resolution SNR-rich 3D images of fluid filled structures with effective background tissue suppression, in rapid scan times.

Fluoro-Triggered MRA Fluoro-Triggered MRA Cardiac Tagging Cardiac Tagging
 
Used to improve visualization of contractile function, this tagging application combines cardiac-gated FastCINE gradient-recalled echo to acquire data throughout the cardiac cycle, with spatial SAT pulses applied throughout the FOV. Using the operator's choice of diagonal stripes or a grid pattern, tagging is applied once per R-R interval immediately following the R-wave ECG trigger, just before the start of data acquisition.
Fluoro-triggered MRA (FTMRA) is designed to capture angiographic images at the precise moment of peak opacification. Rather than automating the image-acquisition upon detection of the bolus arrival, FTMRA allows the operator to trigger each acquisition almost instantly (less than 1 second switch over), as soon as the operator is satisfied with the level of vessel enhancement. The result is an interactive, ASSET compatible, accurate approach to contrast-enhanced MRA.  
     
3D Cardiac Navigator 3D Cardiac Navigator   Spiral Hi-Res & Real-TimeMRA Spiral Hi-Res & Real-Time

The Cardiac Navigator feature combines a cardiac gated, 3D Fast GRE or 3D FIESTA sequence with a navigator pulse that tracks the motion of the diaphragm. By placing the navigator tracker pulse over the right hemi-diaphragm, the acquisition is synchronized to the end-expiration respiratory phase of the patient thus minimizing respiratory ghosting artifacts.
  
Spiral Hi-Res obtains high-resolution images in ultra-fast scan times. This sequence is well suited for obtaining images of the coronary arteries. Spiral Hi-Res acquisitions can be performed in a cardiac gated or non-gated method using a Spiral GRE or SPGR sequence.

Spiral Hi-Res - Spiral Real-Time can be used for the quick localization of anatomy lying in double-oblique planes and in areas where motion can be a problem, such as the coronary arteries.
