Diffusion Magnetic Resonance Imaging (MRI) of the Abdomen
University of Wisconsin, Madison
Summary
The purpose of this research is to see if a new magnetic resonance imaging (MRI) method will be able to improve the images taken of the abdomen. This new method includes some changes to help avoid movements that may disrupt the images like breathing, heartbeats and other involuntary motion that occurs in the abdomen. This study will these methods in healthy volunteers and validate them in patients with known liver metastases in a single contrast-enhanced MRI visit.
Description
This study will develop and validate novel DW-MRI methods with unprecedented robustness to motion, favorable image quality, and quantitative precision for abdominal imaging. Upon successful completion, these methods will have broad applications, including the assessment of cancer, fibrosis and other disease processes in various abdominal organs such as the liver, pancreas, kidneys, bowel and beyond. The primary objective is to demonstrate precise quantitative diffusion parameter mapping that is achieved by the novel, motion-robust, low-distortion DW-MRI methods in a representative and clinica…

Interventions
- DeviceDiffusion Weighted Magnetic Resonance Imaging
Diffusion-weighted (DW)-MRI has a unique ability to probe tissue microstructure without the need for ionizing radiation or intravenous contrast agents. DW-MRI of the abdomen is utilized in detection, staging, and treatment surveillance of malignancies, and has shown great promise in various other applications, including for the assessment of fibrosis in the liver, pancreas, kidneys, and other organs.
