Prostate MRI

Prostate magnetic resonance imaging (MRI) is a highly specialized exam that allows detailed visualization of the prostate gland and surrounding structures. It is an essential tool in the diagnosis and staging of prostate cancer, as well as in the detection of inflammation, nodules and other morphological changes.

What is Prostate Magnetic Resonance Imaging?

Prostate MRI, or Multiparametric Prostate MRI, is a non-invasive imaging exam that uses magnetic fields and radiofrequency waves to obtain detailed images of the prostate and surrounding tissues, such as the seminal vesicles and rectum. It is frequently used to investigate abnormalities on digital rectal examination, elevated PSA (prostate-specific antigen), biopsy planning, or active surveillance in patients with low-risk prostate cancer.

What is the price of Prostate MRI?

The price of prostate magnetic resonance imaging is €275 when performed on a private basis. However, it can also be performed through several agreements, including:

  • ADSE: If prostate MRI is performed through ADSE, the patient only pays a fee of €30;
  • IASFA, ADM GNR, SAD PSP;
  • Insurance Companies: Médis, Multicare, Advance Care, Allianz, Saúde Prime, Future HealthCare, SS CGD, SAMS Quadros, SAMS, Montepio, RNA, Generali, Mudum, MGEN, Aegon, Vitória, Una Seguros, and other insurers.
  • Health Plans: Medicare, Saúde Prime, Future HealthCare, Continente Wells, ACP, and other health plans.
  • Protocols: NRD has protocols with several clinics and institutions that allow you to undergo the exam at very competitive prices. In the case of prostate MRI, the protocol price is €220.

The price varies depending on the healthcare system or insurance you use.

How is it performed?

The patient is positioned lying on their back and a coil is placed over the pelvic region, specifically adapted to capture detailed images of the prostate.

The exam is performed with intravenous contrast (gadolinium), except in specific cases where it is not required.

The MRI scanner is open at both ends.

The procedure usually lasts between 30 and 40 minutes. During the exam, it is necessary to remain still.

Earplugs are provided to reduce perception of the equipment noise.

Prostate Magnetic Resonance Imaging

What does it detect?

Prostate MRI allows the detection of:

  • Suspicious nodules or malignant tumors in the prostate;
  • Changes suggestive of prostatitis (inflammation);
  • Benign prostatic hyperplasia (BPH);
  • Extracapsular extension of tumors;
  • Invasion of the seminal vesicles;
  • Local recurrence after oncological treatment;
  • Among others.

When is it indicated?

The specialist/urologist may recommend Prostate MRI in the following situations:

  • Assessment of suspected prostate cancer (elevated PSA, abnormal digital rectal exam);
  • Planning of targeted biopsies (MRI-ultrasound fusion);
  • Active surveillance of low-risk tumors;
  • Staging of already diagnosed prostate cancer;
  • Re-evaluation after negative biopsies but with persistent clinical suspicion;
  • Detection of local recurrence after surgery or radiotherapy;
  • Among others.

Preparation and guidelines for Prostate Magnetic Resonance Imaging

Before undergoing MRI at NRD, please consider the following factors:

Topic Guideline
Exam Prescription (paper form) You must bring the Exam Prescription in paper format.
Fasting The exam is performed with intravenous contrast, so fasting for 3 hours is generally required (we will confirm this when scheduling).
Early arrival Arrive 15 minutes before the scheduled time.
Medication You may take essential medication with a minimal amount of water.
Metal objects Remove all metal objects (e.g., earrings, bracelets, necklaces, piercings, hairpins, removable prostheses, etc.).
Pregnancy Inform the NRD healthcare professional if you are pregnant.
Previous exams / Tests / Info Bring previous exams, relevant clinical information and recent laboratory tests.
Glucose monitoring implant Do not place the implant, as it will need to be removed before the exam.
Makeup Do not wear makeup, as some products may interfere with the exam.
Valve and/or orthopedic prostheses If you have valve and/or orthopedic prostheses, bring documentation describing their material and composition.
Hearing aids Inform the clinic if you use a hearing aid, as it must be removed before the exam.
Dental prostheses Inform the clinic if you use a dental prosthesis, as it must be removed before the exam. Also inform them if you have dental implants.
Orthodontic appliances Inform the clinic if you have orthodontic appliances. A test may be required to assess compatibility with MRI.
Pacemakers and implantable devices NRD does not perform MRI on people with pacemakers or implantable devices (e.g., cochlear implants). The exam should be performed in a hospital setting.

Throughout the MRI exam, you will be continuously monitored by the NRD imaging technician responsible for your exam. An alert system will also be available for you to activate if needed.

You must remain still during the exam to ensure image quality.

The entire NRD team will be available to answer any questions you may have.

After the exam, you may resume your normal routine.

When and how do you receive the results?

You will receive the MRI results within 7 days after the exam, by email or in paper format at the clinic. On the day of the exam, you will take home a CD with the images.

Where to do it?

MRI can be performed at NRD, at the following address:

Avenida Columbano Bordalo Pinheiro, nº 11-B, ground floor, 1070 – 060 Lisbon (Next to Praça de Espanha)

How long does a Prostate MRI take?

Generally between 30 and 40 minutes.

Do I need any special care after a Prostate MRI?

No. The exam is safe. If contrast is used, it is recommended to stay well hydrated afterwards.

Is a Prostate MRI covered by the National Health Service (SNS)?

No. MRI exams are not reimbursed by the SNS.

Are there risks associated with Prostate MRI? Is it dangerous?

No. Prostate MRI is a simple and safe exam, with no harmful side effects, as it does not use ionising radiation.
If contrast is used, mild allergic reactions may occur, although they are very rare.
In people with severe kidney failure, contrast administration should be avoided.

What are the contraindications for Prostate MRI?

The strong magnetic field used in MRI attracts objects containing iron, which can move with great force.
Metallic objects implanted in the body may pose a risk because they can move or heat up during the exam.

You must inform the staff if you carry any of the following devices or materials:

  • Pacemakers or implanted devices: cardiac pacemakers or defibrillators, ferromagnetic aneurysm clips, electrodes used in deep brain stimulation, cochlear implants, mechanical heart valves and other metallic implants.

  • Metallic foreign bodies: shrapnel or any metallic objects in the body can heat up or move due to the magnetic field and must be assessed beforehand. This includes tiny metal fragments that may have entered the eye from welding, grinding or accidents.

  • Certain eye implants: some types of eye implants with metallic components may pose a risk.

Other situations that may contraindicate the exam include:

  • Known allergy to gadolinium (if contrast is used);

  • Severe renal impairment (when contrast is required);

  • Pregnancy;

  • Medication infusion devices, which may malfunction during MRI, depending on the model;

  • According to the U.S. FDA, some ECG patches and electrodes may cause skin burns during MRI.

This list does not cover all possible MRI contraindications. You should always discuss any concerns with the healthcare professional accompanying you.

Is Prostate MRI performed with contrast?

Yes, in most cases. Contrast helps evaluate vascularisation more accurately and assists in detecting suspicious areas.

Does Prostate MRI replace biopsy?

Not entirely. MRI is very useful for guiding more accurate biopsies, and in some cases may help avoid unnecessary biopsies.
However, the definitive diagnosis of prostate cancer still depends on histological analysis of tissue obtained through biopsy.
