Compressed Sensing GRASP-VIBEBeyond speed. Beyond motion.

With Compressed Sensing GRASP-VIBE, you can expand the patient population eligible for abdominal MRI. Patients with limited breath-hold capability or are unable to follow breathing commands, e.g., patients with dementia, hearing impairment, children¹ or multi morbid patients, can now undergo high-resolution dynamic abdominal imaging under free-breathing with one continuous, push-button exam.
With its intelligent reconstruction and processing framework, Compressed Sensing GRASP-VIBE instantly recognizes different phases of liver dynamics, will automatically label those and output only the clinically relevant information. This allows bringing the advantages of Compressed Sensing GRASP-VIBE to daily clinical routine.

• Perform push-button, free-breathing liver dynamics
• Overcome timing challenges in dynamic imaging and respiratory artifacts
• Expand the patient population eligible for abdominal MRI

Compressed Sensing GRASP-VIBE¹ makes it possible to conduct dynamic contrast-enhanced abdominal exams in free breathing. The acquisition is performed in one continuous run, using a golden-angle stack-of-stars radial scheme that gives robustness towards motion and the flexibility to choose the temporal resolution, which can even vary over the duration of the scan. Reconstruction is performed using a Compressed Sensing GPU accelerated iterative algorithm with per voxel through-time regularization for further improved quality. The combination of features enables for free-breathing abdominal exams with both robust diagnostic image quality and the high temporal resolution required to capture the dynamic phases of contrast enhancement.

Additional features:

• Auto Bolus Detection
• Configuration of exam phases in terms of start time relative to the auto-detected bolus arrival, duration and temporal resolution
• AutoLabeling of relevant phases (pre-contrast, (multiple) arterial, portal-venous and delayed)
• Self-gating for further reduction of residual motion blur
• InlineReconstruction using GPU acceleration allows to access the images after a few minutes – no need to export data to external research servers
• Protocols for the abdomen and the prostate
• Compressed Sensing GRASP-VIBE includes FREEZEit
