Official Description

Magnetic resonance (eg, proton) imaging, abdomen; without contrast material(s), followed by with contrast material(s) and further sequences

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Magnetic resonance imaging (MRI) of the abdomen is a sophisticated imaging technique that utilizes the magnetic properties of hydrogen atoms present in the body to create detailed images of internal structures. This noninvasive procedure does not involve ionizing radiation, making it a safer alternative for patients requiring abdominal imaging. During the MRI, the patient is positioned on a motorized table that moves into a large cylindrical scanner, which houses a powerful magnet. The magnetic field generated by the scanner aligns the hydrogen atoms in the body, and radio waves are then transmitted into this field. As the protons in the nuclei of various tissues respond to the radio waves, they emit specific radiofrequency signals. These signals are captured and processed by a computer, which constructs high-resolution tomographic images in three dimensions. The MRI procedure is particularly useful for diagnosing a range of abdominal conditions, including trauma, suspected internal injuries, unexplained abdominal pain, swelling, and fever. The clarity of MRI images allows for the visualization of structures that may be challenging to assess with other imaging modalities, such as computed tomography (CT). In the context of CPT® Code 74183, the imaging is performed in two phases: first, without the use of contrast material, and subsequently, after the administration of contrast material. This dual-phase approach enhances the diagnostic capability of the MRI by providing comprehensive views of the abdominal area, enabling physicians to identify potential abnormalities such as tumors, abscesses, masses, kidney stones, hernias, appendicitis, infections, and other internal injuries. The detailed images obtained from this procedure are critical for correlating with the patient's clinical signs and symptoms, ultimately guiding appropriate medical management.

1. Indications

Magnetic resonance imaging (MRI) of the abdomen is indicated for a variety of clinical scenarios where detailed visualization of internal structures is necessary. The following conditions and symptoms may warrant the use of this imaging technique:

  • Trauma: MRI is often utilized to assess internal injuries resulting from accidents or falls.
  • Suspected Internal Injury: When there is a clinical suspicion of damage to internal organs, MRI can provide critical information.
  • Unexplained Abdominal Pain: Patients presenting with abdominal pain of unknown origin may benefit from MRI to identify underlying causes.
  • Swelling: MRI can help evaluate the cause of abdominal swelling, which may indicate various pathological conditions.
  • Fever: In cases where fever is present without a clear source, MRI can assist in identifying potential infections or inflammatory processes in the abdomen.

2. Procedure

The MRI procedure for the abdomen, as described by CPT® Code 74183, involves several key steps to ensure accurate imaging results. The following procedural steps outline the process:

  • Step 1: Patient Preparation The patient is prepared for the MRI by removing any metal objects, such as jewelry or clothing with metal fasteners, that could interfere with the magnetic field. The patient may be asked to change into a hospital gown for the procedure.
  • Step 2: Positioning The patient is positioned on a motorized table that slides into the MRI scanner. Care is taken to ensure that the abdomen is centered within the magnetic field for optimal imaging.
  • Step 3: Initial Imaging Without Contrast The MRI begins with the acquisition of images of the abdomen without the use of contrast material. This initial phase captures baseline images that provide valuable information about the abdominal structures.
  • Step 4: Administration of Contrast Material After the initial imaging, a contrast agent is administered intravenously. This contrast material enhances the visibility of certain tissues and abnormalities during the imaging process.
  • Step 5: Further Imaging With Contrast Following the administration of the contrast material, additional sequences of images are obtained. These images allow for a more detailed assessment of the abdominal area, highlighting any abnormalities that may not have been visible in the initial phase.
  • Step 6: Image Processing and Review The captured images are processed by a computer, which generates high-resolution, three-dimensional images of the abdomen. A radiologist reviews these images to identify any potential issues correlating with the patient's clinical signs and symptoms.

3. Post-Procedure

After the MRI procedure is completed, patients are typically monitored for a short period to ensure there are no immediate adverse reactions to the contrast material, if used. Most patients can resume their normal activities shortly after the procedure, as MRI is noninvasive and does not require significant recovery time. However, patients may be advised to drink plenty of fluids to help flush the contrast material from their system. The radiologist will analyze the images and provide a report to the referring physician, who will discuss the findings with the patient and determine any necessary follow-up actions or treatments based on the results.
