Official Description

Magnetic resonance (eg, proton) imaging, fetal, including placental and maternal pelvic imaging when performed; each additional gestation (List separately in addition to code for primary procedure)

Common Language Description

Fetal magnetic resonance imaging (MRI) is a specialized imaging technique utilized to assess potential disorders or anomalies in a developing fetus, particularly when abnormalities are suspected based on ultrasound findings. This procedure is typically conducted during the second and third trimesters of pregnancy, as the size of the fetus in the first trimester is too small for effective imaging. MRI is favored over other imaging modalities that utilize radiation due to its safety profile, making it a non-invasive and non-radiating option for evaluating fetal health. The process involves the use of a strong magnetic field and radio waves to generate detailed images of the fetus, placenta, and maternal pelvic structures when necessary. The patient lies comfortably on a motorized exam table that moves into a large MRI scanner, where the magnetic properties of hydrogen atoms in the body are manipulated to produce high-resolution, three-dimensional images. This imaging technique is particularly valuable for providing comprehensive insights into the development of critical structures such as the brain, chest, and abdomen of the fetus. The procedure typically lasts between 30 to 40 minutes, during which communication between the mother and the technologist is facilitated through a microphone within the scanner. Importantly, the normal application of the magnetic field and radio waves has not been associated with any adverse effects on the mother or fetus.

1. Indications

Fetal magnetic resonance imaging (MRI) is indicated for the evaluation of various conditions and anomalies that may be suspected based on prior ultrasound examinations. The following are specific indications for performing this procedure:

Suspected Fetal Anomalies - Fetal MRI is often utilized when ultrasound findings suggest potential abnormalities in the fetus, allowing for further investigation and assessment.
Assessment of Fetal Development - This imaging technique is employed to provide detailed information regarding the development of critical fetal structures, particularly in cases where ultrasound results are inconclusive.
Evaluation of Placental Conditions - Fetal MRI can also assist in assessing placental abnormalities that may impact fetal health and development.
Maternal Pelvic Imaging - In certain cases, maternal pelvic imaging may be performed concurrently to evaluate any maternal conditions that could affect the pregnancy.

2. Procedure

The procedure for fetal magnetic resonance imaging (MRI) involves several key steps to ensure accurate imaging and patient comfort. The following outlines the procedural steps:

Preparation of the Patient - The patient is instructed to lie comfortably on a motorized exam table. It is essential for the patient to remain still during the imaging process to obtain clear images. The technologist may provide specific instructions regarding hydration or fasting prior to the procedure.
Positioning in the MRI Scanner - Once prepared, the exam table is moved into the MRI scanner, which is a large tunnel-like structure containing a powerful magnet. The patient is positioned so that the area of interest is centered within the magnetic field.
Initiation of Imaging - The MRI machine is activated, and radio waves are transmitted from a scanner within the magnetic field. This process causes the hydrogen atoms in the body to align and emit radiofrequency signals as they return to their normal state.
Image Acquisition - The emitted signals are captured by the MRI machine and processed by a computer to create high-resolution, three-dimensional images of the fetus, placenta, and maternal pelvic area if applicable. The imaging process typically lasts between 30 to 40 minutes.
Communication During the Procedure - Throughout the imaging process, a microphone within the scanner allows the mother to communicate with the technologist, ensuring comfort and addressing any concerns that may arise during the procedure.

3. Post-Procedure

After the completion of the fetal MRI, the patient is carefully monitored as they exit the scanner. There are generally no specific post-procedure care requirements, as the procedure is non-invasive and does not involve any radiation exposure. Patients may resume their normal activities immediately following the MRI. The images obtained will be analyzed by a radiologist, who will provide a detailed report to the referring physician. This report will include findings related to the fetal anatomy, any detected anomalies, and recommendations for further management if necessary. It is important for the patient to follow up with their healthcare provider to discuss the results and any subsequent steps in their care plan.
