Similarities and differences between Likert and PIRADS v2.1 scores of prostate multiparametric MRI: a pictorial review of histology-validated cases.
Similarities and differences between Likert and PIRADS v2.1 scores of prostate multiparametric MRI: a pictorial review of histology-validated cases. Clin Radiol. 2019 Nov;74(11):895.e1-895.e15 Authors: Latifoltojar A, Appayya MB, Barrett T, Punwani S Abstract The UK National Institute for Health and Care Excellence (NICE) 2019 "Prostate cancer: diagnosis and management" guidelines have recommended that all patients suspected of prostate cancer undergo multiparametric magnetic resonance imaging (mpMRI) prior to biopsy. The Likert scoring system is advocated for mpMRI reporting based on multicentre studies that have demonstrated its effectiveness within the National Health Service (NHS). In recent years, there has been considerable drive towards standardised prostate reporting, which led to the development of "Prostate Imaging-Reporting And Data System" (PI-RADS). The PI-RADS system has been adopted by the majority of European countries and within the US. This paper reviews these systems indicating the similarities and specific differences that exist between PI-RADS and Likert assessment through a series of histologically proven clinical cases.

ConclusionsBaseline MRI before CBx during AS results in 50% fewer AS failures and less grade progression over 2 yr. The center where MRI and targeted biopsy is performed may influence AS failure rates.Patient summaryThe ASIST trial randomized 273 men on active surveillance with low-grade prostate cancer diagnosed within the last year to systematic biopsy or magnetic resonance imaging (MRI) with systematic and targeted biopsy. The initial report showed little benefit from targeted biopsy. However, after 2 yr of follow-up we found that baseline MRI before confirmatory biopsy resulted in 50% fewer failures of surveillance...
To compare the diagnostic performance of prostate magnetic resonance imaging (MRI) with an endorectal coil (ERC) to performance without an ERC using either body-array (BAC) or pelvic phased-array coil (PAC) in staging T3 prostate cancer.
AbstractMultiparametric magnetic resonance (MR) imaging of the prostate is an excellent tool to detect clinically significant prostate cancer, and it has widely been incorporated into clinical practice due to its excellent tissue contrast and image resolution. The aims of this article are to describe the prostate MR imaging technique for detection of clinically significant prostate cancer according to PI-RADS v2.1, as well as alternative sequences and basic aspects of patient preparation and MR imaging artifact avoidance.
ConclusionUSPIO-enhanced MRI of the pelvis at 7-T is technically feasible and offers opportunities for detecting USPIO uptake in normal-sized LNs, due to its high intrinsic signal-to-noise ratio and spatial resolution.Key Points• USPIO-enhanced MRI at 7-T can indicate USPIO uptake in lymph nodes based on computed TE images.• Our method promises a high spatial resolution for pelvic lymph node imaging.
To report prostate cancer (PCa) prevalence in Prostate Imaging Reporting and Data System version 2 (PI-RADS v2) categories and investigate the potential to avoid unnecessary, magnetic resonance imaging (MRI)-guided in-bore biopsies by adding clinical and biochemical patient characteristics.
ConclusionsWe demonstrate the safety and feasibility of performing transperineal prostate biopsy using cognitive MRI/biplanar ultrasound fusion guidance. The described technique affords the safety benefits of the transperineal approach as well as obviates the need for a formal fusion platform. Additionally, this method can conveniently be performed under local anesthesia with acceptable tolerability.

However, the hydrophobic nature of fluorinated graphene greatly hinders its application as a biological material. Herein, a nov...
