Extremity radiation exposure in nuclear medicine is a growing concern because it may surpass the maximum permissible dose of 500 mSv. This study aimed to assess the occupational nger dose received by technologists during the preparation and administration of 18F-FDG radiopharmaceuticals in PET-CT whole-body scan procedures. Fifty scans were selecte...

Computed Tomography (CT) is a widely utilized and precious method that is used to determine the severity of COVID-19. High-Resolution Computed Tomography (HRCT) is the inherent protocol for covid pneumonia. The chest severity score is a diagnostic tool to measure the severity of COVID-19 by using quantitative and radiological imaging features. The...

COVID-19, caused by SARS-CoV-2, is a highly infectious global pandemic. Diagnosis relies on the RTPCR test, with Cycle threshold (Ct) value as an indirect measure of viral load. High-resolution computed tomography (HRCT) chest imaging aids in assessing disease severity as a secondary diagnostic tool. This retrospective study aimed to evaluate the r...

Introduction When the patient dose in mammography is assessed, it is important to evaluate both average glandular dose (AGD) and entrance surface dose (ESD). A dose survey on both AGD and ESD in mammography has never been studied in Sri Lanka. Therefore, the present study aimed to evaluate the patient dose received during a full-field digital breas...

Introduction: Variations in the human ocular volumes are related to ocular pathologies including congenital glaucoma, microphthalmus, buphthalmus, and macrophthalmus. As the currently published reference ocular volumes are prone to physiological and racial variations, population specific values may provide more precision in ophthalmological interve...

Magnetic Resonance Imaging (MRI) can be treated as one of the best modalities for volume determination of soft tissue structures. As age and sex show a conspicuous influence upon the ocular volume, this study was aimed to evaluate the age and gender dependent variations in ocular volumes of Sri Lankan adults using MRI. This study was conducted with...
