Quantitative magnetic resonance (QMR) is a sophisticated imaging technique designed for the analysis of tissue composition, including fat, iron, water content, and other components within the body. This method offers enhanced precision compared to traditional imaging studies, such as dual-energy X-ray absorptiometry (DXA). QMR is particularly valuable in various clinical scenarios, including the detection of changes in body composition, evaluation of the effectiveness of medical treatments, monitoring chronic diseases, and assessing growth patterns in specific target areas. The procedure leverages the unique nuclear magnetic resonance properties of hydrogen atoms found in different types of tissues, allowing for the differentiation of signals originating from fat, bone, water, and lean tissue. During the QMR procedure, the patient is positioned on a rolling bed that moves into a specialized square bore chamber, which is enveloped by a resistive electromagnet. This magnet creates a static, low-intensity magnetic field. Subsequently, radio frequency pulses are directed at the target tissue, stimulating the hydrogen nuclei within the magnetic field. The relaxation of these nuclei generates electromagnetic signals that reflect the environment of the protons. These signals are captured and processed to extract data, which is then analyzed using algorithms to produce parametric mapping. The resulting metrics are thoroughly reviewed and interpreted, often in comparison to previous studies, before a comprehensive report is generated. For cases involving multiple organs, the QMR analysis is reported under CPT® Code 0698T, while single organ analysis is reported under CPT® Code 0649T, both of which are performed in conjunction with diagnostic MRI of the same anatomical area during the same session.

The quantitative magnetic resonance (QMR) procedure is indicated for various clinical scenarios, including:
The QMR procedure involves several detailed steps to ensure accurate analysis of tissue composition:
After the QMR procedure, patients may be monitored for any immediate reactions to the imaging process. The results, including the detailed report generated from the analysis, will be discussed with the patient during a follow-up appointment. This report will include findings related to tissue composition and any notable changes or abnormalities detected in the target organ(s). It is important for healthcare providers to review these results in conjunction with the patient's clinical history and any previous imaging studies to make informed decisions regarding further management or treatment options.
