CHOP-fMRU (www.chop-fmru.com), a functional MR Urography (fMRU) post processing tool, was released publicly in 2010. Since its release, I have gotten many questions about various aspects of fMRU post processing. This experience has aided in the development of pMRI (www.parametricmri.com), the successor to CHOP-fMRU. The aim of this electronic poster is to teach fMRU post processing using pMRI through several anonymized examples as well as address common questions that arise. An fMRU report is automatically generated and discussed at the end of each analysis. A comparison between fMRU and MAG3 with examples is included to better understand fMRU functional parameters.

Diffusion weighted imaging (DWI) is used in many diverse clinical and research applications including evaluation of stroke, avascular necrosis, renal tumor classification and others. Standardizing the apparent diffusion coefficient (ADC) value across different studies and institutions has proven difficult due to change in equipment and protocols used. The aim of this electronic poster is to explain this inconsistency in ADC estimation using the pMRI (www.parametricmri.com) software package. Variability in ADC due to b-value selection, low SNR, decay model choice, and theoretical perfusion effects is explained and demonstrated by image analysis of anonymized cases. Read More

Magnetic Resonance Imaging (MRI) R2 and R2* relaxometry has been shown to accurately quantify liver iron content (LIC) without the need for invasive biopsy. However, different post processing techniques and different calibration curves can lead to variability in the measured iron content. A detailed demonstration using the pMRI software package (www.parametricmri.com) of how to analyze R2 and R2* MRI relaxometry images to estimate LIC is presented. Linear monoexpoential, non-linear monoexpoential, biexponential and truncation models are used, compared and discussed. A selection of established LIC vs R2* calibration curves are compared in real time. Anonymized example cases of varying levels of iron overload are used to demonstrate segmentation techniques including region growing and semi-automatic vessel exclusion. After each analysis, a detailed LIC report is automatically generated and explained. Read More
