Background: Radiofrequency ablation (RFA) of subphrenic hepatocellular carcinomas (HCCs) using ultrasound (US) guidance presents a challenge.
Purpose: To evaluate local tumor progression (LTP) and overall survival (OS) after RFA of right posterior subphrenic HCCs, and to identify the risk factors for LTP and OS after RFA.
Material And Methods: We screened patients who underwent US-guided RFA for a single HCC <3 cm in the right posterior subphrenic area.
Background: This study aimed to assess the significance of elevated carbohydrate antigen (CA) 19-9 in postoperative surveillance of extrahepatic bile duct cancer and to identify short-term recurrence predictors.
Methods: This retrospective study included patients with elevated CA 19-9 post-curative surgery. Patients were categorized into positive and negative CT groups based on the detection of recurrence at CA 19-9 elevation.

Background: Patients with borderline resectable (BR) or locally advanced pancreatic cancer (LAPC) require complex management strategies. This study evaluated the prognostic significance of the perichemotherapy skeletal muscle index (SMI) and carbohydrate antigen 19-9 (CA 19-9) in patients with BRPC or LAPC treated with FOLFIRINOX.
Methods: We retrospectively evaluated 227 patients with BR or LAPC who received at least four cycles of chemotherapy between 2015 and 2020.
Article Synopsis
- The study evaluates how the presence of concurrent LR-5 observations impacts the likelihood that LR-3 or LR-4 observations indicate hepatocellular carcinoma (HCC), using a meta-analysis approach.
- The research analyzed data from 29 studies involving 2,591 observations across 1,456 patients, examining the predictive values of LR-3 and LR-4 with and without concurrent LR-5 observations.
- Results showed no significant difference in the positive predictive value for LR-3 and LR-4 observations whether concurrent LR-5 was present or not, suggesting that the presence of LR-5 does not substantially affect HCC diagnosis.
Article Synopsis
- A study examined the effectiveness of combining contrast-enhanced MRI with CT in identifying whether ampullary strictures are malignant or benign, using 90 patients.
- The research involved three radiologists evaluating the diagnostic confidence of using just CT versus the combination of CT and MRI, with results analyzed for accuracy and agreement among observers.
- Findings indicated that adding MRI significantly improved the ability to predict malignancy and demonstrated higher diagnostic accuracy and interobserver agreement compared to CT alone.
Article Synopsis
- The study investigates how excluding intrahepatic segmental vessels from regions of interest (ROIs) impacts liver stiffness measurement (LSM) using magnetic resonance elastography (MRE).
- It compares traditional LSM, which includes these vessels, to a modified LSM version that excludes them, analyzing data from 95 participants.
- Results show that the modified LSM is not only higher but also more sensitive and effective in diagnosing advanced liver fibrosis compared to the conventional method.
Purpose: To identify high-risk computed tomography (CT) features for predicting gallbladder (GB) cancer in patients presenting with localized GB wall thickening.
Methods: This retrospective analysis included 120 patients (mean age: 63.9 ± 10.
Article Synopsis
- The study assessed how preoperative MRI characteristics influence the outcomes of patients with large single hepatocellular carcinoma (HCC) undergoing surgery.
- It analyzed data from 151 patients, focusing on tumor size, margins, and the degree of hypovascularity during MRI, finding that factors like larger tumor size and greater hypovascularity were linked to worse survival rates.
- The results highlighted the need for careful management in patients with specific MRI findings, indicating that these features could help tailor treatment strategies post-surgery.
Article Synopsis
- The study evaluates how well GPT-4 can extract liver cancer-related information (LI-RADS features) from MRI reports written in both Korean and English.
- Researchers created 160 fake reports and considered both these and genuine reports to test the model's accuracy in extracting the relevant data.
- Results showed high accuracy (up to 99% for some features), but the model still needs improvements for consistency and effectiveness in real-world applications.
Rationale And Objectives: To develop and validate a deep learning (DL)-based method for pancreas segmentation on CT and automatic measurement of pancreatic volume in pancreatic cancer.
Materials And Methods: This retrospective study used 3D nnU-net architecture for fully automated pancreatic segmentation in patients with pancreatic cancer. The study used 851 portal venous phase CT images (499 pancreatic cancer and 352 normal pancreas).
Background: To evaluate the efficacy and optimal timing of local treatment in patients with borderline resectable (BR) or locally advanced pancreatic cancer (LAPC) treated with upfront FOLFIRINOX.
Method: Between 2015 and 2020, 258 patients with pancreatic ductal adenocarcinoma (PDAC) were analysed. Treatment outcomes were compared between systemic treatment group (ST) and multimodality treatment groups (MT) using Kaplan-Meier curves and log-rank test.
Purpose: Metabolic dysfunction-associated fatty liver disease (MAFLD) is a new term proposed to replace non-alcoholic fatty liver disease (NAFLD). We analyzed the ultrasonographic findings of MAFLD and NAFLD.
Methods: We conducted a retrospective cross-sectional study of subjects aged ≥19 years who underwent a health screening examination, including ultrasonography, (n = 17,066).

Post-intensive care unit (ICU) syndrome may occur after ICU treatment and includes ICU-acquired weakness (ICU-AW), cognitive decline, and mental problems. ICU-AW is muscle weakness in patients treated in the ICU and is affected by the period of mechanical ventilation. Diaphragmatic weakness may also occur because of respiratory muscle unloading using mechanical ventilators.

Methods: We retrospectively analyzed 190 patients (150 and 40 in the development and test cohort from different centers) with pancreatic cancer who underwent pancreatectomy between January 2018 and June 2021. Radiomics, clinical-radiologic (CR), and clinical-radiologic-radiomics (CRR) models were developed for the prediction of recurrence within 12 months after surgery.
Article Synopsis
- * A retrospective look at 258 preoperative cases revealed that major treatment plan changes occurred in 10.1% of the discussions, primarily due to new insights about tumor characteristics and metastasis.
- * Findings indicate that the additional information provided by radiologists significantly impacts treatment decisions, especially regarding local tumor extent and the presence of distant metastasis.
This prospective pilot study investigated the influence of body position on peak cough flow (PCF) during mechanical insufflation-exsufflation (MI-E) treatment in people with tetraplegia. Fifteen participants with cervical spinal cord injury (C-SCI) were randomized into two groups, which differed in the starting position, that is, the patients were either supine or reclined. Four sessions of MI-E in alternating positions with each session comprising three different maneuvers: five voluntary coughs, five MI-E-assisted coughs, and five MI-E-assisted with manual thrusts were performed with continuous airflow measurement reporting PCF from every cough.
