Magnetic resonance imaging (MRI) of the breast, as described by CPT® Code 77058, refers to a diagnostic imaging procedure that focuses on one breast, utilizing advanced technology to create detailed images without the use of ionizing radiation. This noninvasive technique leverages the magnetic properties of hydrogen atoms present in the body. When exposed to a strong magnetic field and radiofrequency waves, the hydrogen nuclei emit signals that are captured and processed by a computer. The result is high-resolution, three-dimensional sectional images that provide valuable insights into the internal structures of the breast. During the procedure, patients may be positioned on a motorized table and may receive a sedative to ensure they remain still, which is crucial for obtaining clear images. Additionally, the use of contrast material can enhance the visibility of certain tissues or abnormalities, allowing for a more comprehensive evaluation. This imaging modality is particularly useful in assessing various breast conditions and is an essential tool in the diagnostic process.
