Dynamic liver exams can be challenging for patients, including children, the elderly, and the very sick, who cannot hold their breath for the required time or at all.

StarVIBE now delivers robust, free-breathing, and contrast-enhanced exams for these patients by intelligently resisting motion artifacts.

Key benefits:

  • Reliable imaging for a growing patient population, otherwise excluded from MRI
  • Improved treatment due to more accurate results
  • More satisfying patient experience
  • Less time for preparation
  • No need for rescans

“Radial VIBE (StarVIBE) sequence is ideal for MR imaging of pediatric patients. It significantly improves overall image quality and is motion robust, allowing for optimal imaging in free-breathing sedated pediatric patients.“1,2

Dynamic liver imaging remains a contrast-enhanced technique. Using a contrast agent makes it necessary to catch the right point of the arterial phase. If this point in time is missed, crucial arterial information within the liver remains unseen.

TWIST-VIBE offers high temporal and spatial resolution with full 4D coverage for multi-arterial imaging with 100% precise contrast timing.

Body MRI Case with FREEZEit – FNH/Adenoma Distinction with TWIST-VIBE

Key benefits:

  • Robust and fast liver imaging with full 4D coverage
  • Excellent images to plan surgical intervention
  • Reliable imaging from the very first shot
  • Time and cost savings
  • No need for rescans

“TWIST-VIBE revolutionizes the diagnostic possibilities for oncologic imaging. It allows for robust, high temporal and spatial resolution scans, improving lesion detection and characterization. Thus, the detection of otherwise almost invisible liver metastases as well as small HCC foci becomes feasible. This immediately impacts further treatment decisions for our patients.”1

LiverLab provides non-invasive fat and iron evaluation, and enables for trending and/or monitoring of patients suspicious of liver diseases, especially in early disease stages.

The iron and fat values of the liver are important indicators for a variety of serious illnesses. Early evaluation could be a decisive step to better monitor early stages of diffuse liver diseases such as steatosis and hemochromatosis.

LiverLab is robust and fast enough to be implemented in routine clinical imaging with only a few clicks.

 


Your benefits:

• Quantitative liver evaluation

• Robust, clinical, inline workflow, built into the Abdomen Dot Engine

• First Look Dixon:

  o Single breath-hold (in, out, water, fat)

  o Inline, whole liver segmentation

  o Inline liver volume calculation

  o Evaluation suggestion: if fat / iron is detected

With the new CAIPIRINHA (Controlled Aliasing in Parallel Imaging Results in Higher Acceleration) technique, you can accelerate acquisition and significantly reduce 3D breath-holds—without affecting image resolution, coverage, or contrast.
CAIPIRINHA acquisition can be used with 3D TI VIBE or 3D Dixon technique—which provides four contrasts (in phase, opposed phase, fat, and water) in a single short breath-hold

Decrease breath holds – increase workflow
Abdominal MRIs can be challenging—motion (voluntary and involuntary), breath-hold capacity of the patient, acquisition speed, and contrast timing can all impact body imaging. If you could improve your abdominal MRIs, you can yield significant benefits.
Improve your abdominal MRI service and you’ll be able to:

  • Increase patient compliance
  • Enhance patient satisfaction
  • Have consistency among technologists
  • Reduce repeat exams, increase throughput
  • Improve image quality and diagnostic confidence
  • Attract more referrals
  • Meet utilization goals

“With CAIPIRINHA, acquisition times shorter than 10 seconds could have been achieved, which is a tremendous advantage, especially for elderly patients, who are not able to suspend their breath sufficiently. […] CAIPIRINHA-accelerated T1w-VIBE imaging seems to be a very robust and reliable technique. At our institution, this technique is now the clinical standard for abdominal MR studies.”

Liver fibrosis with its associated cirrhosis and hypertension is a highly prevalent disease in the U.S. and traditionally requires biopsy for diagnosis. MR Elastography (MRE) offers the possibility to evaluate relative liver stiffness noninvasively.

Wave Images
2D GRE MRE sequence Is run during application of mechanical waves by active / passive drivers. Wave images allow visualization of resulting shear waves as they travel through the tissue

Coils & Workflow

Standard tools and unique options - Push the efficiency envelope
Flexible Coil Design for Superior Images

The MAGNETOM family of MRI systems features Tim® 4G coils that can now a 60% increase in SNR over the original Tim coil design. These improvements become even more critical in abdominal MRI where technologists often use many signal-started techniques.

 

No matter who comes into the exam room, your technologists can adjust the coil to their unique patient:

Up to 40 channel combination with elements from multiple coils

Tim 4G coils are thin, yet powerful, providing more room in the bore for larger patients.

Increased Efficiency to Meet Utilization Challenges
The need for efficient and effective MRIs has never been greater, particularly while your MRI utilization is under scrutiny. The MAGNETOM family of systems includes a number of features to help you do just that.

Inline Processing
The syngo user interface provides many inline processing features—such as ADC map creation and Maximum Intensity Projections—that free the technologist to do other tasks.

Tim Planning Suite (option)
The Tim Planning Suite allows technologists to easily cover large FOVs, which is especially useful in multi-step scans (e.g., abdomen and pelvis). And set-n-go protocols may be launched to cover complex, multi-step scans with a single click.

Abdomen Dot Engine, TimCT Onco Dot Engine (option)
Dot Engines can significantly cut down on the number of parameter changes and the opportunity for inhomogeneous results. Automation is the key to productivity, and Dot can help automate your MR exams with consistently high results.
