Purpose: This study aimed to analyze the online presence of interventional radiology (IR), and its popularity over time and location, given the reported under-awareness of the specialty.
Materials And Methods: The study analyzed search volumes, searcher demographics, and query type related to IR and its four most searched procedures using Google Trends, Demographics.io, and Also Asked. Search strategies were stratified by volume and region ("Worldwide" and "United States"), and the quality of current patient materials in the first 10 Google search results was analyzed using the DISCERN instrument and Flesch Kincaid levels.
Results: The analyzed search trends demonstrated a slow uptrend in search volume over the past 15 years since 2013, with a CAGR rate of 0.6%. Demographics revealed that 80.9% of searchers were female and over half (51.8%) fell into the age range of 35-54 years old. Geographically, the US had the highest search volume (100) for the term "interventional radiology" and website search results mainly related to patient education about the specialty. The quality of online resources was poor with overall college-level readability, and "What is Interventional Radiology?" was the most popular query.
Conclusions: There is a growing interest in IR procedures in recent years, particularly in the US, with middle-aged females being the most active demographic online. However, online resources containing information on specific IR procedures remain of poor quality. Actions should be taken to improve the quality, accessibility, and awareness of IR-related webpages to increase public knowledge of IR care in the US and abroad.

Objective: [F]FDG imaging is an integral part of patient management in CAR-T-cell therapy for recurrent or therapy-refractory DLBCL. The calculation methods of predictive power of specific imaging parameters still remains elusive. With this retrospective study, we sought to evaluate the predictive power of the baseline metabolic parameters and tumor burden calculated with automated segmentation via different thresholding methods for early therapy failure and mortality risk in DLBCL patients.

A 50-year-old female presented with a 10-day history of progressive swelling and pain in the left lower extremity, ultimately diagnosed with deep vein thrombosis (DVT) and May-Thurner Syndrome (MTS). Initial ultrasound indicated thrombosis involving the left external iliac, femoral, and popliteal veins, among others. Blood tests revealed normocytic anemia, but thrombophilia screening and other blood markers were normal.

Introduction: Portal hypertension is a common complication of liver cirrhosis. Varices are dilated collaterals that develop as a result of portal hypertension at the level of the porto-systemic connections and can cause a shift in the blood flow from high to low pressure. Common locations for porto-systemic shunts are the lower oesophagus and the gastric fundus.

Artificial intelligence (AI) and image processing are revolutionising the diagnosis and management of liver cancer. Recent advancements showcase AI's ability to analyse medical imaging data, like computed tomography scans and magnetic resonance imaging, accurately detecting and classifying liver cancer lesions for early intervention. Predictive models aid prognosis estimation and recurrence pattern identification, facilitating personalised treatment planning.

Background: The purpose of the present study was to evaluate clinicopathological characteristics, patterns of recurrence, survival outcomes, and implications for the addition of chemoradiotherapy for patients with resected perihilar and intrahepatic cholangiocarcinoma (CCA).
Materials And Methods: For the present retrospective study, we identified 38 and 10 patients with resected perihilar and intrahepatic CCA. In perihilar CCA, adjuvant treatment was given as chemotherapy ( = 13) or chemoradiotherapy ( = 10).
