Smart APPLICATION
Efficient applications for enhancing MR imaging
All Around RADAR
RADAR is applicable for routine head examinations
RADAR reduces motion artifacts and increases the ease of use by making it compatible with multiple sequences, all receiver coils and arbitrary cross sections. RADAR can be used in combination with high speed imaging as well. ECHELON Smart Plus's "All Around RADAR" is compatible with TOF sequences, GrE sequences and most of the sequences required for routine brain examinations.
Routine brain imaging
Effects of RADAR on TOF MRA and GrE T2*WI
RADAR has been applied to GrE sequences using a high-precision signal correction technology.
This has enabled the combined use with RADAR for all sequences required in routine brain examinations.
Plaque Imaging
Diagnosis of plaque characterization
Diagnosis of carotid artery plaque characterization requires a high T1 contrast MR image.
The non-gated RADAR-SE method (also known as Radial Scan), maintains a constant TR without being affected by pulsation and can conduct scanning with a high T1 contrast appropriate for diagnosis of plaque characteristics.
SIR Map shows the color map depending on the signal strength ratio after normalizing the ROI signal strength using Reference signal strength.
FatSep is a type of suppression method and is less influenced by changes in magnetic susceptibility.
Multiple images can be obtained with one scan, using the difference in resonance frequency. (chemical shifts of water protons and fat protons)
Assistance of imaging plane setting allows reduction in operation time.
AutoPose Spine is a support function for quick and accurate slice setting. AutoPose processing is executed at the end of the Scanogram, and the scanning positions of the AX / SAG / COR cross sections are calculated simultaneously. The scanning position of the AX cross section can be selected from intervertebral disc, vertebral body and intervertebral disc / vertebral body.
BeamSat TOF
Improving visibility in hemodynamic changes
Selective MRA - Addition of hemodynamic information added to TOF
Pencil-beam type pre-saturation (BeamSat) pulses based on the application of local excitation are used in TOF imaging to selectively suppress some of the blood flow signals required for identification of the hemodynamics.
Selective MRA scans with BeamSat pulses which targets a specified blood flow allowing signals to be suppressed and the dominant regions to be clearly identified. BeamSat pulses can be set to arbitrary positions and angles using a dedicated GUI.
In the BeamSat display, the continuous line represents the nearer part while the broken line represents the farther part than the scanogram; the hatched part is a cross-section between the BeamSat and the scanogram.
Example of BeamSat pulse setting on the left ICA
SAG : Position contacting the nasal root and sella turcica
AX : Position contacting the pyramid and clivus
