# FastMRI in prostate cancer

MRI systems are widely used for the diagnosis of various diseases or for more novel applications like guiding minimal invasive therapeutic interventions. In the era of personalized medicine, medical imaging is the driving force behind these so -called patient- tailored management approaches. Advantages of MRI are being able to detect the disease while at the same time guiding therapies, which enables maximum disease treatment coverage while keeping unwanted side effects to a minimum.

With current MRI systems, diagnostic multiparametric-MRI (mpMRI) examination of the prostate can be performed in approximately 40 minutes or in case of an MRI guided therapeutic intervention in 1-2 hours. In order for healthcare systems to be able to handle the vastly increasing number of patients who require a diagnostic or interventional procedure, new technology is required to reduce scan time without compromising image quality.

In this project we will be investigating speeding up MRI in prostate cancer (PCa) diagnosis and interventions. PCa will serve as a proof of concept disease, with future expansion possibilities to other (clinical) MRI applications. National and European guidelines have recently changed and recommend mpMRI as first-line diagnostic work up in all patients suspected of PCa. MRI is also expected to be more intensively used for surveillance in the setting of a watchful waiting strategy, in order to avoid overtreatment of PCa. Consequently, the number of MRI scans and associated cumulative costs will substantially increase.

We will develop new artificial intelligence (AI) techniques that will make MRI for the diagnosis and interventions in PCa targeted, and therefore faster and more accurate. Innovative harmoniously operating AI techniques will be developed for this purpose: detection, reconstruction, and steering AI (which will target disease and interventional instruments on raw, low resolution, and acquired images), together with corresponding MRI sequence development.
