Lymphoma, the most prevalent hematologic tumor originating from the lymphatic hematopoietic system, can be accurately diagnosed using high-resolution ultrasound. Microscopic ultrasound performance enables clinicians to identify suspected tumors and subsequently obtain a definitive pathological diagnosis through puncture biopsy. However, the complex and diverse ultrasonographic manifestations of lymphoma pose challenges for accurate characterization by sonographers. To address these issues, this study proposes a Transformer-based model for generating descriptive ultrasound images of lymphoma, aiming to provide auxiliary guidance for ultrasound doctors during screening procedures. Specifically, deep stable learning is integrated into the model to eliminate feature dependencies by training sample weights. Additionally, a memory module is incorporated into the model decoder to enhance semantic information modeling in descriptions and utilize learned semantic tree branch structures for more detailed image depiction. Experimental results on an ultrasonic diagnosis dataset from Shanghai Ruijin Hospital demonstrate that our proposed model outperforms relevant methods in terms of prediction performance.

Background And Purpose: To review the existing evidence on multiple timepoint assessments of optic nerve sheath diameter (ONSD) as an indicator of intraindividual variation of intracranial pressure (ICP).
Methods: A systematic search identified studies assessing intraindividual variation in ICP through multiple timepoint measurements of ONSD using ultrasonography. Meta-analysis of studies assessing intraindividual correlation coefficients between ONSD and ICP was performed using a random effects model, and we calculated the weighted correlation coefficient for the expected change in ICP associated with variations in ONSD.

Background And Purpose: Socioeconomic determinants of health impact childhood development and adult health outcomes. One key aspect is the physical environment and neighborhood where children live and grow. Emerging evidence suggests that neighborhood deprivation, often measured by the Area Deprivation Index (ADI), may influence neurodevelopment, but longitudinal and multimodal neuroimaging analyses remain limited.

Background: Because the myocardium thickness and blood flow of the right ventricular (RV) are lower than those of the left ventricle, it is challenging to perceive the RV myocardium in normal individuals. This study aimed to measure the myocardial perfusion in the RV (myocardial blood flow [MBF], myocardial flow reserve [MFR]) from 13N-ammonia PET images and investigate the associations between the MBF and MFR in patients with and without coronary artery disease (CAD) in the right coronary artery (RCA) region. A total 121 MBF and MFR were retrospectively measured from PET images by referring to the radioactivity and clinical blood flow values of the left ventricle.

Background And Objective: Traditional and planimetric plaque indices rely on plaque-disclosing agents and cannot quantify three-dimensional (3D) structures of dental biofilms. We introduce a novel computer-assisted method for evaluating and visualising plaque volume using intraoral scans (IOSs).
Materials And Methods: This was a 4-day, non-brushing, plaque-regrowth study (n = 15).

Introduction: Diversity in medical subspecialties is critical for improving patient care and fostering innovation. However, Neuroradiology remains one of the least diverse Radiology subspecialties, with persistent gender and racial disparities among trainees. This study examines gender, racial, and ethnic representation trends among Neuroradiology fellows over the past decade.
