CPT® Code 77046

Magnetic resonance imaging (MRI) of the breast, as described by CPT® Code 77046, refers to a specialized imaging procedure that is performed on one breast without the use of contrast material. This noninvasive technique leverages the magnetic properties of hydrogen atoms present in the body. When exposed to a strong magnetic field and radio waves, the nuclei of these hydrogen atoms emit radiofrequency signals. A computer then processes these signals to generate high-resolution, tomographic, three-dimensional images of the breast's internal structures. This imaging modality is particularly useful for evaluating breast tissue and identifying any abnormalities such as lesions, tumors, or masses. During the procedure, patients may be administered a sedative to help them remain still, as the imaging requires the patient to lie on a motorized table within a large MRI tunnel. The resulting images provide critical information for diagnostic purposes, aiding healthcare professionals in making informed decisions regarding patient care.
