Variation in the management of benign liver tumors: A European survey and case ...

Background: Management of focal nodular hyperplasia (FNH) and hepatocellular adenoma (HCA), is multidisciplinary and subject to practice variation. We aimed to evaluate variation in clinical management of FNH and HCA in Europe. Methods: We distributed an online survey (November 2021 March 2022) among 294 European experts. The survey included questions on local practice and included eight clinical vignettes. The...

Spectral CT: Current Liver Applications

Using two different energy levels, dual-energy computed tomography (DECT) allows for material differentiation, improves image quality and iodine conspicuity, and allows researchers the opportunity to determine iodine contrast and radiation dose reduction. Several commercialized platforms with different acquisition techniques are constantly being improved. Furthermore, DECT clinical applications and advantages a...

Analysis of 665 thyroid nodules using both EU-TIRADS and ACR TI-RADS classifica...

Background Ultrasound-based classification systems allow stratification of thyroid nodules to recommend fineneedle aspiration (FNA) based on their malignancy risk. However, these have discrepancies that may have an impact in thyroid cancer detection. We aimed to compare European Thyroid Association (EU-TIRADS) and American College of Radiology (ACR TI-RADS), in terms of FNA indication and diagnostic performance...

Risk Biomarkers for Biochemical Recurrence after Radical Prostatectomy for Pros...

Objectives: This study aimed to assess the impact of the covariates derived from a predictive model for detecting extracapsular extension on pathology (pECE+) on biochemical recurrence-free survival (BCRFS) within 4 years after robotic-assisted radical prostatectomy (RARP). Methods: Retrospective data analysis was conducted from a single center between 2015 and 2022. Variables under consideration included prost...

The Effect of Multi-Parametric Magnetic Resonance Imaging in Standard of Care f...

Background: The rising prevalence of nonalcoholic fatty liver disease (NAFLD) and the more aggressive subtype, nonalcoholic steatohepatitis (NASH), is a global public health concern. Left untreated, NAFLD/NASH can lead to cirrhosis, liver failure, and death. The current standard for diagnosing and staging liver disease is a liver biopsy, which is costly, invasive, and carries risk for the patient. Therefore, th...

Editorial

Este editorial será o ultimo que escrevo na qualidade de Presidente da SPRMN. Volvidos quatro anos é tempo de fazer um balanço do que foi a vida da nossa estimada Sociedade Científica, extrapolando e antevendo porventura o futuro. Findo este 2º mandato, a primeira constatação que faço é que o tempo de vigência da Direcção da SPRMN deveria ser mais longo nunca inferior a um espaço de 3 anos. Há muitas coisas par...

Perfusion Magnetic Resonance as a Biomarker for Sorafenib-Treated Advanced Hepa...

Background: Sorafenib is the currently recommended therapy in patients with advanced hepatocellular carcinoma (HCC). Among the several biomarkers available for the evaluation of the therapeutic response and prognosis, there is perfusion magnetic resonance imaging (p-MRI) that, through measurement of the vascular permeability unit (ktrans), may retrieve useful information regarding the microvascular properties o...

All about portal vein: a pictorial display to anatomy, variants and physiopatho...

The portal vein (PV) is the main vessel of the portal venous system (PVS), which drains the blood from the gastrointestinal tract, gallbladder, pancreas, and spleen to the liver. There are several variants affecting the PV, and quite a number of congenital and acquired pathologies.In this pictorial review, we assess the embryological development and normal anatomy of the PVS, displaying selected cases consistin...

Editorial

The current issue of ARP contains an excellent article on artificial intelligence (AI) and its application in the Radiology domain that I would like to draw the reader’s attention. AI is not really a newborn technique and the concept and naming was set up by John McCarthy during the 50’s to define a system that could reason like humans, being self-sufficient in terms of cognitive and learning capabilities. For ...
