ANATOMY isofse 3D volume isotropic fast spin echo with variable refocusing flip angle technique for thin continuous slice imaging. High resolution imaging with T1, T2, PD, IR and FLAIR weighting, provides flexibility in brain studies. isofse can be acquired in one plane (e.g. Sagittal shown to the right) and reformatted in other planes at the same resolution, with no additional scan time. T2 isofse T2 isofse MPR T1 isofse T1 isofse MPR opfse / VIVID Optimized Fast Spin Echo (opfse) with VIVID image processing generates better definition, increased sharpness and reduced image noise. T2 opfse T1 opfse - 3mm thick
Elements from the posterior and anterior sections of the WIT (Workflow Integrated Technology) head coil are automatically selected and combined to support high resolution, low noise acquisitions with RAPID acceleration in all directions. GRADIENT ECHO 3D GEIR PBSG Gradient Echo Inversion Recovery (GEIR) provides enhanced gray/ white matter contrast for improved diagnosis of cognitive disorders. Phase Balanced SARGE (PBSG) a Steady State Gradient Echo with multiple RF phase angles provides high resolution T1/T2 contrast imaging. RADAR Motion compensation with RADAR provides diagnostic results even when imaging uncooperative or infirm patients. With applicability to Spin Echo, FSE, GE, TOF and more, a complete, fully motion compensated brain study can be done with RADAR. RADAR T2 with FatSat RADAR T1 FSE AutoPose Automatically determines and places scan slice locations based on the initial scanogram, saving the operator time and improving consistency of routine brain scans.

DIFFUSION DWI Echelon Oval s Diffusion Weighted Imaging (DWI) provides for detection of water diffusion restrictions that may be due to tumor or stroke. Multiple b-value acquisition, each with independent NSA (Number of Signals Averaged) along with auto generation of Trace and ADC maps minimize the table time for the patient while maximizing image quality. RAPID parallel acceleration reduces susceptibility effects. DWI B1000 ADC B1000 DWI B500 and B1000 DTI TensorSuite adds multi-directional analysis to diffusion imaging. Up to 30 gradient directions can be employed to assess the amount of diffusivity and degree of anisotropy. Fractional Anisotropy (FA) map enables assessment of white matter tracts for diagnosis or surgical planning. Color FA Map Mean Diffusivity Map
Echelon Oval s 34/150 gradients provide the power and speed needed for excellent diffusion imaging. Fast acquisition and inline post processing optimize workflow and throughput. DKI FA Kurtosis Map MK Map Diffusion Kurtosis Imaging (DKI) is an advanced imaging technique for evaluation of neurological disorders. With multiple b-values and up to 30 gradient directions, the resulting Mean Kurtosis (MK) map provides the highest possible signal to resolve white matter fibers even where they cross a potential limitation of Diffusion Tensor Imaging. TRACTOGRAPHY Post-processing of DTI data sets for enhanced, 3D depiction of location and direction of critical white matter tracts. Visualize disruption of white matter due to pathology or injury (e.g. concussion). Tractography generated by Nordic NeuroLab BrainEx from Echelon Oval DTI data sets.
PERFUSION For diagnosis of conditions that disrupt blood perfusion through brain tissue. Contrast and non-contrast techniques available. DSC Blood perfusion assessment through Dynamic Susceptibility Contrast (DSC). Ultra fast EPI acquisitions probe tissue intensity dynamics to depict ischemic tissue and blood flow characteristics. Automatic post processing yields maps of Cerebral Blood Flow (CBF), Cerebral Blood Volume (CBV) and Mean Transit Time (MTT). CBF Map CBV Map MTT Map T2 opfse ASL Arterial Spin Labeling - Blood perfusion assessment without the need for invasive contrast agent. Useful for pediatrics, patients with renal insufficiency or other high risk conditions. A color, relative Cerebral Bloodflow (rcbf) map is automatically generated. rcbf Map
VASCULAR From depiction of veins or arteries to quantification of arterial plaque Echelon Oval provides the tools for complete neurovascular assessment. TIME-OF-FLIGHT Time-of-Flight (TOF) provides high contast blood flow visualization to provide high resolution MRA acquisitions of the head and neck. 3D TOF COW BOLUS IMAGING FLUTE - Fluoro triggering for easy, consistent arterial phase capture. PEAKS, RPEAKS, TPEAKS - Hitachi s centric k-space ordering techniques ensure easy, consistent capture of the critical arterial phase. 3D RF Spoiled SARGE using FLUTE TRAQ - Time resolved MRA (4D imaging) provides insight into the dynamics of blood flow. BSI Blood Sensitive Imaging a 3D multishot Gradient Echo EPI sequence provides high speed T2* weighted images that are sensitive to differences in magnetic susceptibility. Depiction of veins and hemorrhage is possible without a contrast agent. Blood Sensitive Imaging (BSI)
QUANTITATIVE Beyond imaging. MR can acquire information about properties and chemistry of tissue for advanced diagnosis and treatment planning or monitoring. SPECTROSCOPY Chemical Shift Imaging provides for the collection and analysis of metabolite concentrations over an easily and precisely placed multi-voxel region of interest. The CSI Spin Echo sequence acquires information about ten different metabolites and an intuitive analysis task displays the results as both a metabolite map superimposed over the morphological image and spectral graphs for each of the voxels within the ROI.
