Siemens - MRI - Body MRI - Compressed Sensing GRASP-VIBE

Growth with Body MRI – enabled by Compressed Sensing GRASP-VIBE

Many children4, the elderly, or very sick patients may not be able to hold their breath long enough for an abdominal scan with dynamic contrast enhancement. This can either lead to compromised image quality or exclusion of a large part of the population from MRI exams – even though it is the gold standard in liver imaging. This challenge will be overcome with the introduction of Compressed Sensing GRASP-VIBE.

With our disruptive technology, Compressed Sensing GRASP-VIBE you can expand the patient population eligible for abdominal MRI. Patients with limited breath-hold capability or who are unable to follow breathing commands, e.g., patients with dementia, hearing impairment, children3 or multi morbid patients, can now undergo high-resolution dynamic abdominal imaging under free-breathing with one continuous, push-button exam.

Your benefits:

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

TWIST-VIBE showing different perfusion phases

One of the main challenges when using contrast agent is catching the right point of the arterial phase, which differs from patient to patient. If this point in time is missed, crucial information may go undetected. Our solution is TWIST-VIBE: it offers high temporal and spatial resolution for multi-arterial imaging with 100% precise contrast timing.

Your benefits:

  • Robust and fast imaging with full 4D coverage
  • Excellent images to plan surgical interventions
  • Reliable images and greater detail for every exam
  • Time and cost savings
  • No need for rescans

Involuntary motion – be that breathing, swallowing or bowel peristalsis – can lead to severe artifacts, compromising diagnosis. StarVIBE is a 3D T1-weighted gradient-echo sequence that efficiently encounters involuntary motion in the body and is the method of choice in every region where involuntary motion (lung, pelvis, orbits, head & neck, bowel) might compromise image quality.

Your benefits:

  • Patients can breathe freely throughout the scan
  • Reliable imaging of patients otherwise excluded from MRI
  • Free-breathing T1-weighted 3D measurements with very high spatial Resolution
  • StarVIBE effectively compensates breathing, swallowing, bowel motion and other sources of motion artifacts
  • Reduced need for rescans due to substantially reduced motion artifact

Siemens - MRI - LiverLab - Image - Evaluation result of liver fat and/or iron (HISTO)
Evaluation result of liver fat and/or iron (HISTO)

Evaluating the fat and iron content of the liver is an important step in monitoring early stages of liver diseases. As steatosis and hemochromatosis are becoming more prevalent in industrialized countries, the demand for liver evaluation is growing.
LiverLab enables non-invasive identification of patients with fatty liver and iron overload already at an early disease stage. This helps to minimize the need for biopsy.

Your benefits:

  • Non-invasive evaluation method for liver fat and iron content
  • Fast and reproducible results without post-processing
  • One robust and fast clinical workflow
  • Time and cost savings

MR Elastography
Elastogram calculated from wave image providing reliable data about tissue stiffness

Liver fibrosis is an excessive accumulation of extracellular matrix proteins including collagen that occurs in most types of chronic liver diseases. Advanced liver fibrosis results in cirrhosis, liver failure, and portal hypertension, where liver transplantation may be the only treatment option. Diagnosis traditionally requires liver biopsy and there is acknowledged need for accurate less invasive methods to detect and follow chronic liver disease. These challenges have led to increasing interest in MR Elastography as a clinical and research tool

 

Your benefits:

  • Helps to evaluate changes and therefore loss in functionality of the liver tissue
  • Additional MR tool set to evaluate liver diseases non-invasively
  • Different approach for improved treatment decisions, especially in liver fibrosis

RESOLVE is a diffusion-weighted imaging (DWI) technique that reduces blurring and susceptibility to artifacts. It is largely free of distortions and delivers sharp images at higher spatial resolution. RESOLVE is especially attractive for the evaluation of smaller lesions in a wide range of examinations.

Your benefits:

  • High-quality, high-resolution DWI and DTI
  • Reduced susceptibility to blurring artifacts
  • Insensitivity to motion-induced phase errors
  • Reduced SAR in comparison to TSE-based methods

See what’s possible in Body MRI

Whether it’s about imaging patients who cannot hold their breath or about finding the right time point of the arterial phase after contrast injection, FREEZEit takes Body MRI to the next level. Check out these cases to experience the convincing results in a clinical and research set-up.


Siemens - MRI - Image - Clinical Case - Cholangiocarcinoma – metastatic disease

In the case of a 63-year-old male patient whose CT scan showed lesions in the left inferior lobe of the liver, TWIST-VIBE helped to see if there is a pancreatic carcinoma or any hepatic metastases in addition to the suspected cholangiocarcinoma. The results led to a sound therapeutic decision by continuing chemotherapy instead of going for surgery and further liver resection.

FNH/Adenoma distinction with TWIST-VIBE

In the case of a 54-year-old female patient who showed intrahepatic masses during a sonograph examination, the TWIST-VIBE sequence helped to identify the lesions and distinguish between an Adenoma and FNHs (Focal nodular hyperplasia). Multiple arterial phases made it possible to see the best phase of lesion enhancement, to adequately characterize, and decide for a corresponding treatment.

Hepatoblastoma follow-up after post right Hepatectomy with StarVIBE

In the case of a 3-year-old hepatoblastoma patient, StarVIBE allowed a free-breathing and contrast-enhanced follow-up examination after partial liver resection.4 With its higher spatial resolution and excellent motion robustness, StarVIBE helped to exclude local recurrence. In addition, the absence of ionizing radiation when using MRI is an advantage for pediatric patients who often undergo further follow-up examinations throughout their lifetime.
