Magnetic Resonance Imaging (MRI) for breast cancer is a vital diagnostic tool that aids physicians in evaluating the dimensions, positioning, and extent of tumor spread. This procedure is typically utilized for patients who have received a breast cancer diagnosis or for those with suspicious lesions that are challenging to assess through other diagnostic methods, such as mammography or ultrasound.

During a breast cancer MRI scan, patients are positioned within a large magnet that creates a powerful magnetic field, which induces resonance in the hydrogen nuclei within the body. The resulting signals are then processed by a computer to produce detailed images. To enhance the contrast of the images, a contrast agent known as gadolinium may be administered prior to the scan.

The benefits of breast cancer MRI scans encompass their non-invasive nature, high resolution, and capability to provide multi-planar imaging. However, there are limitations to consider, such as the high cost, contraindications for certain patients (e.g., those with pacemakers or metallic implants), and the possibility of false-positive or false-negative results. Consequently, physicians must carefully weigh the advantages and disadvantages of breast cancer MRI scans and make an informed decision based on the individual patient's circumstances.
