Results: Prostate cancer was diagnosed in 108 of the 256 patients (42.2%). Additional targeted biopsies were performed in 54 of 119 cases with abnormal MRI findings. Twenty-seven of those 54 cases (50%) were diagnosed as malignant both on additional and systematic sampling bi...
Urology 66 (Suppl 5A): S47–S51 Experience counts: MRI-based prostate-cancer staging Controversy rages over which imaging tech- nique to use in the localization and staging of prostate cancer. Many small studies have been done, with contradictory results, but the differences in the imaging ...
Magnetic resonance imaging (MRI) provides detailed anatomical images of the prostate and its zones. It has a crucial role for many diagnostic applications. Automatic segmentation such as that of the prostate and prostate zones from MR images facilitates many diagnostic and therapeutic applications. Howe...
1.5-T multiparametric MRI using PI-RADS: a region by region analysis to localize the index-tumor of prostate cancer in patients undergoing prostatectomy 1.5-T multiparametric MRI using PI-RADS: a region by region analysis to localize the index-tumor of prostate cancer in patients undergoing ...
Figure 1.Transperineal prostate biopsy. A further technique gaining popularity is MRI fusion biopsies. In this technique, a pre-procedure MRI is obtained and any lesions can be mapped on real time US during transperineal biopsies in order that these are specifically targeted. MRI is increasingly be...
Results A total of 2034 men were invited to participate; of 411 who attended screening, 408 consented to receive all screening tests. The proportion with positive MRI results (score, 3-5) was higher than the proportion with positive PSA test results (72 [17.7%; 95% CI, 14.3%-21.8%] vs...
Experience, meticulous image analysis, including morphological and functional images at the same time are factors, which can reduce false positive results. Formulating reports Reporting at our institution is performed in a structured way on a free text basis. All patients undergoing MRI-TRUS fusion gu...
Fig. 1.Biogenesis of exosomes. Extracellular constituents can enter the cells through the process of endocytosis and plasma membrane invagination. The consequent bud formation of the luminal side of the cell results in the formation of early sorting endosomes. The early sorting endosome could fuse wi...

Multiparametric MRI of the prostate is now recommended as the initial diagnostic test for men presenting with suspected prostate cancer, with a negative MRI enabling safe avoidance of biopsy and a positive result enabling MRI-directed sampling of lesions. The diagnostic pathway consists of several step...
