Official Description

Quantitative magnetic resonance image (MRI) analysis of the brain with comparison to prior magnetic resonance (MR) study(ies), including lesion identification, characterization, and quantification, with brain volume(s) quantification and/or severity score, when performed, data preparation and transmission, interpretation and report, obtained without diagnostic MRI examination of the brain during the same session

Common Language Description

Quantitative magnetic resonance image (MRI) analysis of the brain, as described by CPT® Code 0865T, involves a sophisticated process that utilizes advanced software to evaluate brain lesions. This procedure is particularly relevant in monitoring conditions such as multiple sclerosis, where changes in the brain can be subtle yet significant over time. The analysis begins with the acquisition of new MRI images, which are then compared to previously obtained MRI studies. This comparison is crucial for identifying and characterizing lesions, as it allows for the quantification of changes in the brain's structure and volume. The software overlays the new images with prior segments, facilitating a detailed examination of the brain's condition. The process includes the identification of diseased areas, which are analyzed to assess their progression or regression. The quantitative analysis not only focuses on lesion identification but also includes brain volume quantification and severity scoring, when applicable. This comprehensive approach ensures that the results are contextualized against normative data based on age and gender, providing a benchmark for comparison. Once the analysis is complete, a detailed report is generated, summarizing the findings and highlighting any significant changes observed. This report is then transmitted to the physician or qualified professional for further review and interpretation. It is important to note that this procedure is performed without a diagnostic MRI examination of the brain during the same session, ensuring that the analysis is distinct and focused solely on the quantitative assessment of previously acquired images.

1. Indications

The quantitative magnetic resonance image analysis of the brain using CPT® Code 0865T is indicated for the following conditions:

  • Multiple Sclerosis - This procedure is particularly useful in monitoring the progression of lesions associated with multiple sclerosis, allowing for the assessment of disease activity over time.
  • Brain Lesions - It is indicated for the identification and characterization of various brain lesions, providing critical information for diagnosis and treatment planning.
  • Neurological Disorders - The analysis can be beneficial in evaluating other neurological conditions where brain structure changes are of concern.

2. Procedure

The procedure for quantitative MRI analysis of the brain involves several key steps:

  • Step 1: Image Acquisition - The process begins with the acquisition of new magnetic resonance images of the brain. These images are essential for the subsequent analysis and must be of high quality to ensure accurate results.
  • Step 2: Data Preparation - Once the new images are obtained, they are prepared for analysis. This involves uploading the acquired MRI study into specialized software designed for quantitative analysis.
  • Step 3: Image Overlay - The software overlays the new MRI images with previously acquired MRI segments. This step is crucial as it allows for a direct comparison of the brain's condition over time, highlighting any changes in lesions or brain volume.
  • Step 4: Lesion Identification and Characterization - The software identifies and characterizes lesions present in the brain. This includes assessing the size, shape, and location of the lesions, which are critical for understanding the patient's condition.
  • Step 5: Quantification - The analysis quantifies changes in the brain, including lesion volume and overall brain volume. This quantification is essential for tracking disease progression and response to treatment.
  • Step 6: Report Generation - After the analysis is complete, a detailed report is generated. This report includes the findings from the quantitative analysis, comparisons to normative data, and any significant changes observed in the brain's structure.
  • Step 7: Review and Transmission - The output images and the report are reviewed for quality before being transmitted to the physician or qualified professional for further interpretation and clinical decision-making.

3. Post-Procedure

Post-procedure care for the quantitative MRI analysis typically involves the physician reviewing the generated report and images. The physician may discuss the findings with the patient, including any implications for treatment or further diagnostic testing. If the quantitative analysis is performed concurrently with a diagnostic MRI examination of the brain, the final report can be generated and returned within 30 minutes, allowing for real-time interpretation. This timely review facilitates immediate clinical decision-making based on the most current data available. Additionally, any necessary corrections to the report can be made by the physician before finalization, ensuring accuracy in the documentation of the patient's condition.
