An MRI (magnetic resonance imaging) scan uses magnetism to build up a detailed picture of certain areas of the body. You may be given an injection of dye into a vein to improve the images from the scan.
In some hospitals, you may have an MRI scan before a biopsy. Specialised scans called multi-parametric MRI scans can give doctors more detailed images of the body. These images give doctors more information about a suspected area of cancer. This can help them to specifically target suspicious areas of the prostate if a biopsy is needed. Based on the information that the doctor gets from the image, you may decide together that a biopsy is not needed.
