| Abstract | Background Sickle cell disease (SCD) is a common inherited hemoglobinopathy associated with vaso-occlusive events that can mimic pulmonary embolism (PE), leading to the frequent use of computed tomography pulmonary angiography (CTPA). However, trends in CTPA utilization over time remain unclear. This study aims to evaluate temporal trends and recurrent imaging patterns. Methods A retrospective cohort study was conducted at Salmaniya Medical Complex, Bahrain, including SCD patients who underwent CTPA for suspected PE between April 15, 2013, and April 15, 2024. Descriptive statistics were used to report the frequency of recurrent scans, whereas linear regression analysis was employed to assess trends in CTPA utilization over the study period. Results The study included 1,084 patients (median age: 35 years, 55.7% male) with SCD who underwent a total of 1,934 CTPA scans. CTPA utilization remained stable from 2014 to 2020, averaging 10.0–13.6 scans per month. However, a significant surge was observed post-2020, coinciding with the COVID-19 pandemic, peaking in 2023, with an average of 31.3 scans per month, indicating a 2.9-fold increase (p = 0.03). During the study period, 415 patients (38.3%) underwent recurrent CTPA scans, with one-third (32.5%, n = 276) of these scans occurring within a 6-month interval. Although the PE positivity rate was lower in recurrent scans than in initial scans, the difference was not statistically significant (8.8% vs. 10.5%; p = 0.22). Conclusions CTPA utilization among SCD patients remained stable for several years but increased significantly after 2020, coinciding with the COVID-19 pandemic. A substantial proportion of scans were recurrent, with many occurring within a short interval. Moving forward, efforts should focus on mitigating radiation exposure through low-dose protocols and investigating potential factors contributing to the recent increase in scan utilization. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
