What is this test?

Scrotal MRI is an imaging test that produces detailed pictures of the scrotum, which contains the testes and supporting structures. In this test, contrast material is not injected into your bloodstream.

Why might I need this test?

Your clinician may order scrotal MRI to evaluate unexplained swelling, pain, a suspected mass, injury, inflammation, or reduced blood flow. It may also help characterize abnormalities that were identified by another imaging test, such as ultrasound.

How is the test performed?

You will lie on a table inside an MRI scanner while the machine takes a series of images. The scanner may make loud knocking or clicking sounds, and the test usually takes 30 to 60 minutes. A technologist will guide you and may ask you to remain still or briefly hold your breath.

How do I prepare for the test?

Follow your imaging center's instructions. MRI generally does not require fasting or bowel preparation, but you may be asked to limit food or drinks beforehand. Tell the care team about all implants, medications, and medical devices, because some contain metal or may affect MRI safety.

Frequently asked questions

Does this MRI use contrast material?
No. This is a noncontrast MRI, so no contrast material is injected into your bloodstream. You may still receive fluids or medication through a vein if needed during the examination.
Is a scrotal MRI the same as an ultrasound?
No. Ultrasound uses sound waves and is often used first for many scrotal conditions, while MRI creates more detailed images using magnetic fields and radio waves. MRI may be used when ultrasound results are unclear or more detailed evaluation is needed.
What if I have a metal implant or I feel claustrophobic?
Tell the imaging team about any implants, devices, or metal in your body before the scan, even if you have had a previous MRI. The care team can assess safety and may offer options to help with anxiety or claustrophobia.
