Summary: This study aimed to identify quantitative CT features for distinguishing well-differentiated pancreatic neuroendocrine tumors (PNETs) from poorly differentiated pancreatic neuroendocrine carcinomas (PNECs). The results showed that arterial/portal absolute enhancements were independent predictors with good diagnostic accuracy for differentiating between PNETs and PNECs. Arterial lesion enhancement had the highest diagnostic performance.

Summary: A radiomics nomogram was established and validated for preoperative prediction of lymph node metastasis in periampullary carcinomas. The radiomics signature, constructed by seven selected features, showed a close relationship to LN metastasis in both the training and validation sets. The nomogram, incorporating radiomics signature and CT-reported LN status, demonstrated favorable calibration, discrimination, and clinical utility for predicting LN metastasis.

Summary: The combination of MDCT with serum CA199, CA242, and CEA significantly improves the diagnostic efficiency of pancreatic cancer and has guiding significance for preoperative and prognostic evaluation. High levels of CA199, CA242, and CEA expression are associated with poor survival rates in patients with pancreatic cancer.

Summary: High levels of serum miR-135 and miR-20a were found in patients with GC, with significant differences compared to the non-GC group and healthy control group. The combined detection of miR-135 and miR-20a with MDCT showed higher sensitivity and specificity in diagnosing GC than single detection methods. This multi-detector approach improved the accuracy of GC diagnosis and is valuable in clinical practice.

Summary: This study investigated the value of MSCT in preoperatively diagnosing PNI of PAC. The results showed significant differences in clinical characteristics and MSCT features between PNI and Non-PNI groups. The combination of fat tissue classification around the celiac trunk with other factors improved the diagnostic efficacy. Preoperative diagnosis of PAC PNI can be accurately achieved by evaluating abdominal enhanced MSCT images.

Summary: The photon-counting detector (PCD) is a new technology that provides significant benefits for cardiac and coronary artery imaging. Compared with conventional CT, PCCT has improved capabilities such as multi-energy capability, increased spatial resolution, reduced radiation exposure, and optimized use of contrast agents. It also overcomes limitations of traditional CCT/CCTA, such as reducing artifacts and enabling more precise assessment of stenosis and plaque characteristics. PCCT also has potential applications in characterizing myocardial tissue using a double-contrast agent.

Summary: Numerous studies have found an association between low levels of uric acid (UA) and Parkinson's disease (PD), suggesting that low UA may contribute to oxidative stress and the degeneration of dopamine neurons, leading to the onset and progression of PD symptoms. However, recent research has raised questions about this explanation, proposing that low UA may be a biomarker rather than a causative factor for PD.

Summary: The purpose of this study was to assess the differences in academic rank between academic emergency radiologists and other subspecialty diagnostic radiologists. The study found that academic emergency radiologists are less likely to achieve advanced rank compared to non-emergency radiologists who have similar career length and gender matches, and this difference persists even after adjusting for h index.

Summary: Lesch-Nyhan disease is a neurodevelopmental disorder caused by variants in the HPRT1 gene. HGprt deficiency leads to metabolic changes in cells. This study found significant changes in gene and protein expression caused by HGprt deficiency, with differences depending on the cell type. In neural stem cells, HGprt deficiency mainly affects the WNT signaling pathway and mitochondrial F0F1 ATPase.
