Quantitative magnetic resonance image (MRI) analysis of the brain with comparison to prior magnetic resonance (MR) study(ies), including lesion detection, characterization, and quantification, with brain volume(s) quantification and/or severity score, when performed, data preparation and transmission, interpretation and report, obtained with diagnostic MRI examination of the brain (List separately in addition to code for primary procedure)

Quantitative magnetic resonance image (MRI) analysis of the brain involves the use of advanced software to assess and compare newly acquired MRI images with previously obtained MRI studies. This procedure is particularly useful in identifying and analyzing lesions in the brain, which may be indicative of various neurological conditions, such as multiple sclerosis. By overlaying multiple images, the software allows for a detailed examination of changes in the brain over time, facilitating the detection and characterization of diseased areas. The analysis includes quantifying brain volumes and, when applicable, providing a severity score. The process begins with the upload of the most recent MRI study, which is then compared to earlier images to highlight any significant changes. The output images generated from this analysis are carefully reviewed for quality assurance before being processed to quantify the observed changes. Additionally, the results are benchmarked against normative data based on age and gender to provide context for the findings. A comprehensive report is subsequently generated, summarizing the analysis and findings, which is then transmitted to the physician or qualified professional for further evaluation. When this analysis is performed concurrently with the diagnostic MRI examination of the brain, the final report can be produced and made available for real-time review within a 30-minute timeframe, allowing the physician to assess the quantitative data alongside the MRI images and make any necessary adjustments before finalizing the report.
