Multiparametric Magnetic Resonance Imaging (MRI) of the prostate

Multiparametric MRI of the prostate is a leading edge medical imaging technology. It uses a powerful magnetic field, generally 1.5 or 3.0 Tesla, and radio waves to obtain very precise images of the prostate. This examination is completely non-invasive, painless, and does not involve the use of X-rays. 

The prostate MRI objectives are multiple :

  • Prostate cancer screening and diagnosis: detecting the presence of suspect lesions, evaluating their precise location, measuring their size and characteristics
  • Evaluation of the tumour extension: determining whether or not the tumour is localised or has progressed, checking neighbouring tissue
  • Assisting treatment strategy: guiding the targeted biopsies, helping choose the most suitable treatment, defining what stage the disease has reached
  • Follow-up and surveillance: checking development of a known tumour, evaluating response to treatment, detecting any return of the disease

This examination is based on a number of imaging sequences that, when combined, provide a complete analysis of the prostate. The T2 weighted sequences make it possible to observe the structure and anatomy of the prostate while the diffusion imaging helps to identify cellular abnormalities. When the injection of a contrast agent (Gadolinium) is necessary, the dynamic imaging makes it possible to study the vascularisation of tissue to better distinguish between healthy tissue and suspect tissue.  

During the examination you will be asked to lie down on the imaging table and an antenna is placed on your abdomen that captures the radio signals emitted by the tissue. In rare cases an endorectal antenna may be used but this remains exceptional. 

The importance of expertise

A multiparametric MRI of the prostate can be carried out and the results interpreted at most radiology units in Belgium. However, a rigorous quality chain is essential to guarantee a precise diagnosis as a basis for discussing an appropriate personalised treatment. 

At the Willy Grégoir Prostate Cancer Centre we apply the highest quality standards at each stage of the process as testimony to our commitment to diagnostic excellence over many years.
