Official Description

Brain imaging, less than 4 static views; with vascular flow

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Brain imaging, as described by CPT® Code 78601, involves the use of scintigraphy to obtain static images of the brain, specifically with the inclusion of vascular flow imaging. This procedure utilizes a radiolabeled isotope tracer, which is a radioactive substance that helps visualize blood flow and brain activity. The primary purpose of this imaging technique is to document brain death, making it a critical procedure in certain medical evaluations. During the procedure, the patient is carefully positioned on an imaging table, and a gamma camera is aligned to capture images of the entire head and neck region. An intravenous line is established to facilitate the injection of the radiolabeled isotope tracer directly into the patient's circulatory system. The imaging process begins promptly after the isotope bolus reaches the neck, allowing for the assessment of vascular flow as it progresses through the brain. The imaging captures static views from multiple angles, including anterior, right lateral, and left lateral positions, with each view being recorded for approximately five minutes. This method allows for detailed visualization of the brain's structure and blood flow, which is essential for accurate interpretation by the physician, who subsequently provides a comprehensive written report of the findings. It is important to note that CPT® Code 78601 is specifically designated for cases where vascular flow studies are included alongside the static imaging, distinguishing it from other codes that may apply to different imaging scenarios.

1. Indications

The procedure associated with CPT® Code 78601 is indicated for specific clinical scenarios where brain imaging is necessary to assess brain function and vascular flow. The following conditions may warrant the use of this imaging technique:

  • Brain Death Evaluation This procedure is primarily performed to document brain death, providing critical evidence in determining the absence of brain activity.
  • Assessment of Cerebral Blood Flow It is utilized to evaluate cerebral blood flow, which can be essential in diagnosing various neurological conditions.
  • Investigation of Neurological Symptoms The imaging may be indicated in patients presenting with unexplained neurological symptoms, where understanding brain perfusion is necessary for diagnosis.

2. Procedure

The procedure for CPT® Code 78601 involves several key steps that ensure accurate imaging of the brain with vascular flow assessment. The following outlines the procedural steps:

  • Patient Positioning The patient is positioned on the imaging table, ensuring that the head and neck are properly aligned for optimal imaging. This positioning is crucial for the gamma camera to effectively capture the necessary views of the brain.
  • Intravenous Line Establishment An intravenous line is established to facilitate the administration of the radiolabeled isotope tracer. This step is essential for ensuring that the tracer is delivered directly into the circulatory system, allowing for accurate imaging of vascular flow.
  • Injection of Radiolabeled Isotope Tracer The radiolabeled isotope tracer is injected through the intravenous line. This tracer is critical for visualizing blood flow within the brain, as it emits radiation that can be detected by the imaging equipment.
  • Imaging Process Imaging begins as soon as the isotope bolus reaches the neck. The gamma camera captures static images from multiple angles, including anterior, right lateral, and left lateral positions. Each view is recorded for approximately five minutes, allowing for detailed assessment of the brain's structure and blood flow.
  • Data Interpretation After the imaging is completed, the physician interprets the collected data. This interpretation is vital for understanding the findings and determining the clinical implications of the imaging results.

3. Post-Procedure

Post-procedure care for patients undergoing CPT® Code 78601 typically involves monitoring for any immediate reactions to the radiolabeled isotope tracer. Patients may be observed for a short period to ensure there are no adverse effects from the injection. Additionally, the physician will provide a written report detailing the findings from the imaging study, which is essential for further clinical decision-making. Patients may be advised on any necessary follow-up appointments or additional testing based on the results of the imaging. It is also important to inform patients about the safety of the radiolabeled isotope used, as it is designed to minimize radiation exposure while providing valuable diagnostic information.
