Based on the well-known role of peritumour characterization in cancer imaging to improve the early diagnosis and timeliness of clinical decisions, this study innovated a state-of-the-art approach for peritumour analysis, mainly relying on extending tumour segmentation by a predefined fixed size. We present a novel, adaptive method to investigate the zone of transition, bestriding tumour and peritumour, thought of as an annular-like shaped area, and detected by analysing gradient variations along tumour edges. For method validation, we applied it on two datasets (hepatocellular carcinoma and locally advanced rectal cancer) imaged by different modalities and exploited the zone of transition regions as well as the peritumour ones derived by adopting the literature approach for building predictive models.

Purpose: Transarterial radioembolization (TARE) with Yttrium-90 resin microspheres is a treatment option for patients with intrahepatic cholangiocarcinoma (ICC). However, optimising the timing of TARE in relation to systemic therapies and patient selection remains challenging. We report here on the effectiveness, safety, and prognostic factors associated with TARE for ICC in a combined analysis of the prospective observational CIRT studies (NCT02305459 and NCT03256994).

Article Synopsis
  • Benign renal tumors like renal oncocytoma (RO) can be misdiagnosed as malignant renal cell carcinomas (RCC) due to similar imaging characteristics, prompting the need for better diagnostic systems using machine learning and radiomic features.* -
  • A study analyzed CT images from 77 patients, extracting features from tumor volumes and surrounding transition zones (ZOT), and used a genetic algorithm to select the most effective features to build a decision tree classifier for distinguishing RO from clear cell RCC (ccRCC).* -
  • Results showed that ZOT features were the most predictive, with the best model achieving a ROC AUC score of 0.87 when feature selection was applied to the entire dataset, while the version

Background: Intrahepatic cholangiocarcinoma (ICC) is the second most common primitive liver cancer and is rising in incidence worldwide. Given its low survival and resectability rates, locoregional therapies such as Yttrium-90 transarterial radioembolization (Y-TARE) are increasingly being employed. This retrospective study aim was to confirm and update our previous results about overall survival (OR), safety, and efficacy of Y-TARE in patients with unresectable/recurrent ICC.

Background And Aim: The American College of Radiology (ACR) defines "actionable findings" the ones requiring a special communication between radiologists and referring clinicians, suggesting to organize their categorization in a three-degree scale on the basis of the risk for the patient to develop complications. These cases may fall in a grey-zone communication between different care figures with the risk of being underestimated or even not being considered at all. In this paper, our aim is to adapt the ACR categorization to the most frequent actionable findings encountered when reporting PET/CT images in a Nuclear Medicine Department, describing the most frequent and relevant imaging features and presenting the modalities of communication and the related clinical interventions that can be modulated by the prognostic severity of the clinical cases.

The liver is a secondary and often collateral target of COVID-19 disease but can lead to important consequences. COVID-19 might directly cause a high number of complications in patients with pre-existing chronic liver disease, increasing their risk of hepatic decompensation. Moreover, it also determines indirect consequences in the management of patients with liver disease, especially in those suffering from decompensated cirrhosis and HCC, as well as in the execution of their follow-up and the availability of all therapeutic possibilities.

Biliary anatomic variations are usually asymptomatic, but they may cause problems in diagnostic investigations and interventional and surgical procedures, increasing both their technical difficulty and their postoperative complication rates. The aim of the present study was to evaluate the prevalence of anatomic variations in the intrahepatic biliary ducts (IHBD) in relation to demographical and clinical characteristics in a large study population requiring magnetic resonance cholangiopancreatography (MRCP) for various clinical conditions. The possible association between IHBD and extrahepatic biliary ducts (EHBD) variants was then explored.

Hepatocellular carcinoma (HCC) and clear cell renal carcinoma are both frequent cancers, especially in patients with risk factors such as cirrhosis in the first case or genetic mutations such as Li-Fraumeni syndrome in the second case; however, their synchronous appearance is very rare especially in young patients with no apparent predisposing factors. We describe the case of a 33-year-old woman with acute pain onset in right hypochondrium. The ultrasound (US) imaging and the contrast-enhanced computed tomography (CECT) of the abdomen revealed 2 abdominal masses: one in the VI-VII segments of the liver and the other one in the right kidney.
