Given the increasing global prevalence of metabolic syndrome, this study aimed to assess the potential of MRI-derived radiomics in noninvasively grading fibrosis. The study included 79 prospectively enrolled participants who had undergone MRE due to known or suspected liver disease between November 2022 and September 2023. Among them, 48 patients were diagnosed with histopathologically confirmed liver fibrosis.

- The study investigates the use of Large Language Models (LLMs), specifically ChatGPT, in medical education, focusing on their ability to enhance the learning experience for medical students.
- Using 151 radiology exam questions, the performance of OpenAI's GPT-3.5 and GPT-4 was assessed, with GPT-4 showing significantly higher accuracy (88.1%) compared to GPT-3.5 (67.6%).
- Results suggest that LLMs, especially GPT-4, could serve as effective study resources for medical students preparing for exams, although users should be cautious of potential inaccuracies in responses.
Intussusception in adult patients is a rare medical finding, which is accompanied by an underlying tumor in some cases. However, no accepted method has been established to identify patients at risk for tumor-related intussusception. This study aimed to identify imaging features as predictors for tumor-related intussusception.

- The study aimed to compare the effectiveness of dual-energy CT (DECT) iodine maps with traditional CT scans in diagnosing non-occlusive mesenteric ischemia (NOMI) using data from 142 patients who underwent surgery.
- Findings showed that iodine concentration measurements in the late arterial phase provided superior diagnostic ability (AUC of 0.966) for identifying ischemic bowel compared to both portal venous phase and conventional CT scans.
- The study concluded that late arterial phase iodine maps markedly enhance diagnostic accuracy for acute bowel ischemia, showing a very high sensitivity (100%) and specificity (96.48%) at a defined cutoff.
To establish dual-energy-derived iodine density reference values in abdominopelvic organs in a large cohort of healthy subjects. : 597 patients who underwent portal venous phase dual-energy CT scans of the abdomen were retrospectively enrolled. Iodine distribution maps were reconstructed, and regions of interest measurements were placed in abdominal and pelvic structures to obtain absolute iodine values.
