: An update of the 2010 published ESUR recommendations of MRI of the sonographically indeterminate adnexal mass integrating functional techniques is provided. An algorithmic approach using sagittal T2 and a set of transaxial T1 and T2WI allows categorization of adnexal masses in one of the following three types according to its predominant signal characteristics. T1 'bright' masses due to fat or blood content can be simply and effectively determined using a combination of T1W, T2W and FST1W imaging...

BACKGROUND: Diffusion-weighted imaging (DWI) is a magnetic resonance imaging (MRI) technique that was established in the clinical routine primarily for the detection of brain ischemia. In the past 15 years its clinical use has been extended to oncological radiology, as tumor and metastases can be depicted in DWI due to their hypercellular nature. PRINCIPLES: The basis of DWI is the Stejskal-Tanner experiment. The diffusion properties of tissue can be visualized after acquisition of at least two diffusion-weighted series using echo planar imaging and a specific sequence of gradient pulses...

Prostate cancer is the second most prevalent cancer in men worldwide and its incidence is expected to double by 2030. Multi-parametric magnetic resonance imaging (MRI) incorporating anatomical and functional imaging has now been validated as a means of detecting and characterising prostate tumours and can aid in risk stratification and treatment selection. The European Society of Urogenital Radiology (ESUR) in 2012 established the Prostate Imaging-Reporting and Data System (PI-RADS) guidelines aimed at standardising the acquisition, interpretation and reporting of prostate MRI...

Many aspects of magnetic resonance (MR) operation are not directly regulated by law but in standards, guidelines and the operating instructions of the MR scanner. The mandatory contents of the operating instructions are regulated in a central standard of the International Electrotechnical Commission (IEC) 60601-2-33. In this standard, the application of static magnetic fields in MRI up to 8 Tesla (T) in the clinical routine (first level controlled mode) has recently been approved. Furthermore, the equally necessary CE certification of ultra-high field scanners (7-8 T) in Europe is expected for future devices...

Multiparametric MR of the prostate provides an extremely accurate diagnosis and offers an excellent negative predictive value for cancers which biopsies struggle to detect. Combined with biopsies they consolidate both positive and negative biopsy results and allow patients to be offered more appropriate treatments (active monitoring, radical treatment in full knowledge of the topography of the lesions involved, or local treatment, etc.). The investigation does not require advanced equipment and can be carried out in any MR centre although it needs to follow a technical protocol described in the European guidelines (ESUR 2012)...

Magnetic resonance imaging of rare cystic prostate cancers using multiparametric MRI (mp-MRI, 3 Tesla) shows, especially in solid tumor masses, the criteria of ESUR-MR classification with a PI-RADS >3 ("probably malignant"). In association with additional morphological evidence of intracystic hemorrhage and evidence of villous tumor nodules and irregular septa on the cyst wall, further malignancy criteria are met. MRI complementary to TRUS may be useful for targeted biopsy in solid tumor areas.
