Imaging Applications
Both 1.5T and 3T MRI systems at WIMR are accredited by the ACR (American College of Radiology) MRI accreditation program, and the ACRIN (ACR Imaging Network) CQIE (Centers for Quantitative Imaging Excellence) program. MRI systems at the CSC are also ACR accredited for MRI. One system at the CSC and one system at the Research Park Clinic are ACR accredited for breast MRI. Anatomic imaging is available for neuro, cardiac, MSK, abdominal, thoracic, peripheral, vascular, breast, and spine applications. Imaging can be performed as multi-slice 2D and volumetric 3D acquisitions (including BRAVO and CUBE for 3D isotropic T1- and T2-weighted imaging). Parallel imaging (ASSET/ARC) is available for many imaging sequences. Gadolinium-based contrast agents can be used for an extra charge, following screening for NSF safety. Available FDA-approved Gd-based agents are Omniscan (gadodiamide), MultiHance (gadobenate dimeglumine), and Ablavar (gadofosveset trisodium). Imaging can be performed after the administration of a contrast agent for tumor imaging. FDA-approved contrast agents supplied by the investigator can be also used for human subjects. Contrast agents that are not FDA-approved and supplied by the investigator can be used after appropriate IACUC approval for animal subjects.
General
Fat/Water Separated Imaging
In addition to conventional fat saturation methods, fat/water separated imaging (i.e., generation of fat-only and water-only images) can be produced using the GE Healthcare IDEAL and Flex sequence variations.
Dynamic Contrast Enhanced Perfusion Imaging
DCE (T1-weighted) perfusion imaging using a Gd-based contrast agent is most commonly used for imaging tumor perfusion. Perfusion maps can be generated as part of image analysis provided by the IMAC.
MR Spectroscopy and Spectroscopic Imaging
Magnetic Resonance Spectroscopy (MRS) and Spectroscopic Imaging (MRSI) are available for neuro, breast, liver, and prostate applications.
Realtime Imaging
Interactive realtime imaging can be performed using the rtHawk-based system from HeartVista, Inc. which interfaces with the GE MRI systems. Applications include cardiac and vascular imaging, and neuro and body MR-guided interventions. While not FDA-approved, this system has been extensively tested, and is used in several ongoing research projects.
Neuro, Spine, and MSK
Dynamic Susceptibility Contrast Perfusion Imaging
DSC (T2*-weighted) perfusion imaging can be performed following injection of a Gd-based contrast agent. This type of imaging is commonly used in the clinic to assess the effects of stroke. Perfusion parameter maps, including the parameters rCBF, rCBV, FMT, Tmax and MTT, can be produced using locally-developed post-processing software, or software supplied by GE.
ASL Perfusion Imaging
Perfusion imaging can be performed without exogenous contrast agents for the assessment of cerebral blood flow in human subjects using Arterial Spin Labeling.
Susceptibility-Weighted Imaging
Susceptibility-Weighted Imaging (SWI) is available using the SWAN technique.
Diffusion-Weighted Imaging and Diffustion-Tensor Imaging
Diffusion-Weighted Imaging (DWI) and Difusion-Tensor Imaging (DTI, including tractography) can be performed to assess the restriction of water diffusion in tissue. Basic online diffusion parameter maps (ADC, FA) are automatically generated. DTI tractograms can be reconstructed as part of image analysis provided by the IMAC.
Functional Neuro MRI (fMRI)
Functional Neuro MRI (fMRI) is available at WIMR for research applications, and at other sites for clinical applications. Dedicated research staff acquire and process fMRI data. Commonly used paradigms include language and motor tasks such as word generation and unilateral finger tapping. Assistance is available for development of new fMRI tasks. Research fMRI studies are processed off-line using common software packages such as AFNI. Clinical fMRI studies are processed using PRISM.
Neuronavigation
Using the FDA-approved Clearpoint™ system from MRI Interventions, image-guided targeting of deep structures in the brain is possible, and can be used to guide interventions including DBS electrode placement and drug infusions.
Imaging near Orthopedic Implants
With the MAVRIC SL imaging option from GE Healthcare, imaging near orthopedic implants, such as knee and hip implants, is greatly improved by acquiring multiple image volumes with discrete frequency offsets, view-angle tilting, and specialized reconstruction techniques.
Body and Breast
Liver Fat-Fraction
Quantitative assessment of liver fat-fraction and iron content can be assessed using the IDEAL-IQ sequence.
Hyper-Polarized Gas Imaging
Facilities are available at WIMR for generating hyper-polarized Helium (He-3) or Xenon (Xe-129) gas for lung and airway imaging. Hyper-polarization of Carbon (C-13) is also available for pre-clinical imaging on the Varian 4.7T system.
Functional Body MRI
Functional Body MR Imaging is available for a wide variety of imaging scenarios. Applications include Renal BOLD and ASL perfusion imaging, quantitative liver imaging using IDEAL IQ, and liver stiffness assessment using MR Elastography (MRE).
Cardiac and Vascular
Cardiac MRI
A full suite of Cardiac MRI techniques is available, including function assessment with 2D FIESTA, real-time perfusion and motion imaging with MR-Echo, cardiac tagging, double- and triple-inversion recovery (Double-/Triple-IR) imaging, myocardial R2*(=1/T2*) mapping for iron overload evaluation, 2D- and 3D-Cardiac IDEAL for water/fat separation, delayed enhancement (DE) / late-gadolinium enhanced (LGE) imaging for myocardial viability imaging,nd 3D Heart for coronary artery imaging.
Vascular Imaging
Dedicated vascular imaging techniques, including MR Angiography (MRA) and MR flow measurements are available. Standard clinical MRA methods including Time-Of-Flight (TOF) MRA, 2D Phase Contrast (PC) MRA, non contrast-enhanced (NCE) Inhance methods from GE Healthcare, and contrast enhanced imaging including TRICKS and Fluoro-Triggered 3D MRA (with ARC parallel imaging and ROSE) are available. PC-VIPR (Phase Contrast with Vastly-undersampled Isotropic Projection Reconstruction Trajectories) is a 3D volumetric flow imaging method, developed at UW-Madison, that while not yet FDA-approved, has been widely tested and validated and is used in multiple research projects. MRA post-processing is available, and can included advanced methods for reconstruction of 3D flow data. Additional vascular imaging methods are under continual development in the MRI lab, and may also be available for research projects.
