Publication Evaluation of Normal Appendix by Computed Tomography: A Retrospective Cross-sectional Study(Rapti Academy of Health Sciences (RAHS), 2025) B. C., Bom; K. C., Achhita; Subedi, Raj Kumar SubediAbstract: Introduction: The appendix is a blind-ended tubular gut structure which arises from caecum with considerable variation in position and morphology. Acute appendicitis remains one of the most common causes of acute abdomen that requires emergency radiological investigation. The objective of this study was to evaluate normal appendix by computed tomography (CT) of abdomen in patients with non-appendicular symptoms. Methods: This was a retrospective cross-sectional study based on record review of patients undergoing CT abdomen attending Rapti Academy of Health Sciences (RAHS) without suspicion of acute appendicitis from October 2024 to March 2025. Axial including reformatted coronal and sagittal images were evaluated for appendix visualization, its diameter, wall thickness, intra-luminal contents and tip position. Data collection was done after receiving ethical approval from the Institutional Review Committee of RAHS. Data analysis was performed using Statistical Package for the Social Sciences version 27. Results: Among 216 patients (109 males, 107 females; mean age of 46.8 years), appendix visualization rate was 96.8% (98.1% in female and 95.4% in male). The mean appendix diameter was 6.13±1.03 mm (range: 3.6-10.0 mm) with no significant sex difference. Mean wall thickness was 2.55 ± 0.53 mm. Air was the predominant intra-luminal content (50.7%), followed by collapsed lumen (35.9%). The most common appendix tip position was retro-caecal (49.3%), followed by pelvic (22.0%). Conclusion: There was higher appendix visualization rate in our study using CT. As normal appendix can measure >6 mm in CT, ultrasound size criteria for appendicitis is not applicable in CT.Publication Spectrum of HRCT Chest Findings in RT-PCR positive COVID-19 Patients at a Tertiary Care Center in Mid-Western Nepal: A Retrospective Cross-Sectional Study(Rapti Academy of Health Sciences (RAHS), 2024) B. C., Bom; Khanal, Bipin; K. C., Achhita; Subedi, Raj Kumar; K. C., AnuprashAbstract: Introduction: Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) causes a pulmonary infection called as coronavirus disease (COVID-19). High-resolution computed tomography (HRCT) of the chest plays a crucial role in diagnosis, assessing the lung involvement with its severity in COVID-19. The objective of this study was to describe the pattern of HRCT chest findings in lab-proven, real- time RT-PCR-positive COVID-19 patients. Methods: This was a descriptive cross-sectional study conducted at Rapti Academy of Health Sciences (RAHS), the then COVID-19 patient treatment site in Lumbini province, from February 2021 to October 2021 among 78 RT-PCR-positive COVID-19 patients based on HRCT chest findings. Data collection was done after receiving ethical approval from the Institutional Review Committee of RAHS. Data analysis was performed using Statistical Package for the Social Sciences version 27. Results: Among 78 RT-PCR-positive COVID-19 patients, 51 were male and 27 were female, with a mean age of 51.28±14.35 years. HRCT chest showed ground glass opacities (GGO) in 74 (94.87%), followed by atelectatic band in 24 (30.77%), interlobular septal thickening in 22 (28.21%), consolidation in 20 (25.64%), GGO and consolidation in 17 (21.79%), crazy-paving pattern in 11 (14.1%), and other chest findings in 5 (6.41%) patients. Conclusion: The most common HRCT chest findings of COVID-19 were ground-glass opacities, while atelectatic band, interlobular septal thickening, consolidation, and crazy-paving pattern were other important findings. Thus, HRCT chest imaging is crucial for both diagnosing and assessing the severity of COVID-19 patients.
