Introduction: Magnetic Resonance Imaging is a common diagnostic tool used to evaluate various clinical conditions. Different fat suppression techniques such as Short Tau Inversion Recovery and Dixon are employed to enhance diagnostic accuracy. The choice of fat suppression sequence varies based on availability and performance. This study aimed to compare Contrast Ratio and Contrast-to-Noise Ratio of Short Tau Inversion Recovery and Dixon technique.
Methods: This observational cross-section study was performed in the Department of Radiology from 8 September 2023 to 7 September 2024 after the approval by the Institutional Review Committee (Reference number: 151/080/081(6-11)E2). Using a complete census method during the study period, MRI-lumbar spines of 384 adult patients were included in the study. Signal intensity values of the lesion, adjacent normal tissue, and noise were recorded for calculation of Contrast Ratio and Contrast-to-Noise Ratio.
Results: Among 384 cases, 191 (49.74%) were male and 193 (50.26%) were female with median age 46 (IQR: 35-60) years. The median value of contrast ratio and contrast-to-noise ratio were 0.31 (IQR: 0.14-0.50) and 8.74 (IQR: 3.82-15.50) respectively for STIR sequence while median value of contrast ratio and contrast-to-noise ratio were 0.44 (IQR: 0.19-0.74) and 11.95 (IQR: 5.38-23.18) respectively for Dixon sequence, higher than Short Tau Inversion Recovery.
Conclusions: Contrast Ratio and Contrast to Noise Ratio were found higher and background noise lower for Dixon compared to Short Tau Inversion Recovery.

Background: The estimated glucose disposal rate (eGDR) is a validated surrogate marker of insulin resistance. However, its association with stroke and dementia in nondiabetic populations remains insufficiently investigated.
Methods: This prospective cohort study included nondiabetic participants from the UK Biobank.

Background: Genetic variation contributes to atrial fibrillation (AF), but its impact may vary with age. The Research Program contains whole-genome sequencing of data from 100 574 adult participants with linked electronic health records.
Methods: We assessed clinical, monogenic, and polygenic associations with AF in a cross-sectional analysis, stratified by age: <45 years (n=22 290), 45 to 60 years (n=26 805), and >60 years (n=51 659).

Introduction: The high mortality of Coronavirus Disease 2019 (COVID-19) highlights the need for safe and effective antiviral treatment. Small molecular antivirals (remdesivir, molnupiravir, nirmatrelvir/ritonavir) and immunomodulators (baricitinib, tocilizumab) have been developed or repurposed to suppress viral replication and ameliorate cytokine storms, respectively. Despite U.

To develop and validate a deep-learning-based algorithm for automatic identification of anatomical landmarks and calculating femoral and tibial version angles (FTT angles) on lower-extremity CT scans. In this IRB-approved, retrospective study, lower-extremity CT scans from 270 adult patients (median age, 69 years; female to male ratio, 235:35) were analyzed. CT data were preprocessed using contrast-limited adaptive histogram equalization and RGB superposition to enhance tissue boundary distinction.
