Challenges of Operationalizing a Mobile Computerized Tomography Unit: Experience Report from the ProPulmão Project

Abstract

The ProPulmão pilot project, launched in 2023, aimed to screen and analyze the epidemiological profile of lung cancer in remote communities across Bahia, Brazil, where access to imaging exams is limited. Recognizing the critical role of low-dose computed tomography (CT) in reducing lung cancer mortality, the project employed a mobile unit equipped with a 16-channel CT scanner and the necessary medical infrastructure to screen asymptomatic smokers and ex-smokers who had quit smoking up to 15 years ago. While the initiative proved effective, it encountered significant logistical challenges, particularly with internet connectivity and power supply—both essential for the consistent operation of the CT unit and the transmission and storage of medical images. Despite these obstacles, the project successfully facilitated early detection of lung cancer cases, underscoring the importance of such screening programs. The challenges led to refining work protocols, including improved image storage techniques, a deeper understanding of managing medical image servers, and enhanced communication between the technical and medical teams. These experiences contributed to the ProPulmão project's success. They provided valuable insights for implementing similar initiatives in other states across Brazil, thereby promoting greater accessibility and early detection in underserved areas.
