Prostate MRI - Specialists and Information

Magnetic resonance imaging (MRI) is one of the imaging techniques used in medical diagnostics. It allows for the very precise visualization of fine tissue structures in particular. You have the option of having your prostate examined via MRI by a radiologist. The focus is on specific features and changes in the tissue of your prostate gland.

Unlike conventional magnetic resonance imaging, the innovative multiparametric MRI is considered a highly sensitive diagnostic tool for analyzing the prostate.

This radiation-free method offers the highest level of precision and allows for the accurate detection of changes in the prostate. Its particular advantage lies in the reliable differentiation between aggressive and benign tumors.

Multiparametric MRI combines an MRI scan (nuclear magnetic resonance) with at least two additional imaging techniques.

These are used to:

• Determining the exact composition of the tissue, as well as
• classifying cancerous tissue

Your doctor can identify the nature and extent of a tumor in detail and draw conclusions about its biology. This helps avoid unnecessary surgical procedures and biopsies.

Starting at age 45, doctors recommend an annual prostate exam as part of cancer screening. This initially takes the form of a digital rectal exam, which provides your doctor with information about any changes. 

In addition, the PSA (prostate-specific antigen) test is another option for early detection. Unlike the digital rectal exam, you are responsible for covering the cost of this blood test yourself.

If your doctor detects a significantly elevated PSA level, a prostate MRI is helpful in confirming the diagnosis. This is typically the case when prostate cancer is suspected.

Even after a prostate biopsy (tissue sample from the prostate), the examination is helpful in determining a further treatment plan. In addition, prostate diagnostics within the field of radiology offers the possibility of comprehensive treatment monitoring and follow-up care.

If the findings from prostate cancer screening are normal, a biopsy can often be avoided by performing a multiparametric MRI (mp-MRI).

Only if the findings are abnormal is a tissue sample essential for determining the aggressiveness of prostate cancer. 

You are also responsible for covering the costs of the mp-MRI yourself. It is not covered by statutory health insurance. In many cases, however, private health insurance companies are willing to cover the costs.

The examination is performed on an outpatient basis. You will lie down and receive a contrast agent intravenously beforehand. This allows for a precise visualization of the tissue.

As is typical with an MRI, the machine emits a loud clicking noise. You will be given headphones to reduce the volume. Throughout the examination, which lasts about 20–30 minutes, you will remain in constant contact with the staff via an intercom system.

The radiology practice asks that you bring any existing medical reports with you to the exam.

These include, for example:

• X-ray images or
• ultrasound or CT scans
• Current PSA level and
• creatinine level

The creatinine lab value has nothing to do with your prostate; rather, it indicates possible kidney impairment. The contrast agent would be counterproductive in this case.

A radiologist (a specialist in radiology) is responsible for evaluating and interpreting the MRI images and making the diagnosis.

There is a magnetic field inside the MRI scanner itself. This requires you to remove all metal objects before entering the examination room.

These include, for example:

• Watches
• Piercings and
• Clothing containing metal.
• Medical devices (glasses, removable dentures)

Your doctor will check for other possible exclusion criteria, such as the presence of fixed dental prostheses, pacemakers, surgical clips, and similar items.

After the exam, you don’t need to take any further precautions. You may resume your normal daily activities immediately. The results of the radiological exam will be sent to your treating physician, who will then discuss them with you.

The MRI exam itself is considered a particularly low-risk procedure. In very rare cases, minor complications may occur that could require further treatment.

These are primarily minor and superficial skin irritations, which are usually associated with tattoos. Ringing in the ears caused by the clicking sound is also rare, but it typically subsides quickly.

Hypersensitivity reactions related to the contrast agent are extremely rare. This may cause mild nausea, which subsides after a few hours. An allergic reaction to the contrast agent is very rare. Medical staff can immediately recognize an allergic reaction and treat it.

The high precision of this imaging procedure allows for a reliable diagnosis and, consequently, particularly early tumor detection when necessary.

The earlier a diagnosis is made, the sooner treatment can be initiated. The prognosis for the course of the disease in its early stages is correspondingly positive.

Prostate MRI is a completely painless examination used when prostate cancer is suspected, for treatment planning, and to monitor treatment success.

It is performed on an outpatient basis, often avoids unnecessary biopsies, and provides an extremely precise diagnosis.
