Software tool to facilitate the import and visualization of multi slice, spin echo MRI data sets encompassing the liver and cardiac tissue, with functionality independent of the MRI equipment vendor. The operational principle is based on fitting signal decay curves to the image signal intensities at the different echo times for the MR data set on a voxel by voxel (3 D pixel) basis to determine transverse relaxation rate (R2) images, that may be further transformed by a defined calibration to provide a quantitative measure of liver iron concentrations in vivo and fitting signal decay curves to magnetic resonance image signal intensities acquired at different echo times on a voxel by voxel (3 D pixel) basis to determine the signal decay rate (R2*) and time (T2*)The obtained results can be used for the following purposes:1. Supporting clinical diagnoses about the status of liver iron concentration and cardiac iron.2. Supporting the subsequent clinical decision making processes.3. Supporting the use in clinical research trials, directed at studying changes in liver iron concentration as a result of interventions.4. It contains an image viewer for importing DICOM images, browsing through patient datasets, viewing images and performing region of interest analysis.
An individual software program or group of programs, routines or algorithms that add specific image processing and/or analysis capabilities to a magnetic resonance imaging (MRI) system configuration. A basic set of applications programs and routines are included with such computer-controlled imaging systems and they can be upgraded to correct programming errors or to add new system capabilities. Some applications software programs or program packages must be combined with specific hardware or firmware configurations in order to function as intended. Applications program packages are typically identified by a proprietary name and "version" or "upgrade" number.
