HOW TO MEASURE WITH OSIRIX LITE SOFTWARE

rda files were extracted and analyzed for fat fraction using Targuin GUI and the custom MATLAB program. Both Horos and OsiriX Lite (32-bit) are not FDA approved however.

The MRS sequence was run after the clinical MRI on four quadrants of the liver.Ī 30x30mm voxel was placed in four quadrants of the liver and the sequence was run three times with a brief 3 second breath hold. Horos software provides increased accuracy and confidence in determining the. Users can store annotations and measurements along with images or videos within patient cases. We recruited patients undergoing abdominal MRI with and without contrast on the 1.5T MRI system. Osirix is available for Mac, iPhone, iPad and Android. MR spectroscopy was found to be the most accurate technique and was subsequently used to measure fat fractions in the four quadrants of the liver in the research subjects (n=5).įor the prosepctive component of this project, Lung density was evaluated for each animal and at each time-point by Hounsfield Unit (HU) measurements. The other MR sequences were analyzed using Osirix Lite software. Based on phantom studies, were performed using the Osirix Lite Software. The MR spectrums then were analyzed using a custom MATLAB program (Figure 3) to determine fat fractions utilizing four of the six known lipid peaks. The MR spectrum was first loaded on Tarquin GUI in order to extract values from the spectrum (Figure 2). All images were analyzed using OsiriX software (OsiriX Lite v.8.5.2.

This study was approved by the institutional IRB. The accuracy of the following MRI techniques were determined on a 1.5T MRI system using lipid phantoms (Figure 1) ranging from 0% to 50% lipid: In Phase/Opposed Phase T1 imaging, Throughout the experiments, longitudinal measurement of murine intestinal wall.
