Purpose: To evaluate the accuracy of magnetic resonance elastography (MRE) in comparison to contrast-enhanced computed tomography (CE-CT) for early diagnosis and prediction of severity in acute pancreatitis (AP).
Materials And Methods: This cross-sectional prospective study included 76 patients with suspected AP who underwent both CE-CT and 3.0T MRE within 24 hours of hospital admission. Pancreatic stiffness, CT severity index (CTSI), Acute Physiology and Chronic Health Evaluation (APACHE)-II, and Bedside Index for Severity in AP (BISAP) scores were comparatively evaluated using data from the first 24 hours of admission, and diagnosis and severity of AP were confirmed according to the revised Atlanta Classification (2012). The accuracy of MRE for predicting disease severity was compared with that of CE-CT and the clinical scoring systems using area under the receiver-operating curve (AUC) analysis.
Results: AP was confirmed in 56/76 patients (73.7%). Pancreatic stiffness values of >1.47 kPa showed significantly better diagnostic performance than CE-CT (AUC: 0.993 vs. 0.818, P < 0.001) along with greater sensitivity (96.4% vs. 78.6%, P = 0.006) and accuracy (96.1% vs. 81.6%, P = 0.007). Ten patients (10/76; 13.2%) had clinically severe AP. The accuracy of pancreatic stiffness >2.47 kPa was comparable to that of the CTSI, APACHE-II and BISAP scores for predicting severe AP (accuracy = 85.5%, 75.0%, 88.2%, and 78.9%, respectively). The pairwise comparisons were not significant after Bonferroni correction (P < 0.008 [0.05/6]), with P values of 0.008 (MRE vs. CTSI), 0.823 (MRE vs. APACHE-II) and 0.414 (MRE vs. BISAP).
Conclusion: Early MRE is a useful, noninvasive method for both diagnosis and early severity assessment of AP. We recommend MRE at hospital admission for initial evaluation of AP.

Introduction: Recent advancements in medical imaging, such as point shear wave elastography (pSWE), offer non-invasive methods to assess tissue stiffness and structural changes. This study explores the use of pSWE to evaluate pancreatic stiffness and dimensions in three different pancreas parts.
Methods: This study was conducted at diagnostic radiology department, King Abdulaziz University Hospital, Jeddah, between June 2022 and November,2022.

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a liver disease that is strongly associated with chronic low-grade inflammation. Stage 3 of MASLD is characterized by excessive formation of connective tissues, commonly referred to as liver fibrosis. Although numerous inflammatory markers have been identified and extensively studied, including the tumor necrosis factor-α and interleukin-6 have been studied [Byrne CD, Targher G.

Background: The typical pathological feature of pancreatic ductal adenocarcinoma (PDAC) is a significant increase in stromal reaction, leading to a hypoxic and poorly vascularized tumor microenvironment. Tumor cells undergo metabolic reprogramming, such as the Warburg effect, yet the underlying mechanisms are not fully understood.
Methods: Interference and overexpression experiments were conducted to analyze the in vivo and in vitro effects of USP7 on the growth and glycolysis of tumor cells.

The delivery of nanoparticles to tumors has been shown preclinically to be improved by microbubble-mediated ultrasound. However, the mechanisms and biological effects are not fully understood. In this study, we explored the influence of the tumor microenvironment on nanoparticle uptake and microdistribution both with and without ultrasound and microbubble treatment.

The physical characteristics of the tumor microenvironment (TME) include solid stress, interstitial fluid pressure, tissue stiffness and microarchitecture. Among them, abnormal changes in tissue stiffness hinder drug delivery, inhibit infiltration of immune killer cells to the tumor site, and contribute to tumor resistance to immunotherapy. Therefore, targeting tissue stiffness to increase the infiltration of drugs and immune cells can offer a powerful support and opportunities to improve the immunotherapy efficacy in solid tumors.
