Kampala, Uganda – In a groundbreaking effort to elevate medical imaging practices, Dr. Geoffrey EREM from the College of Health Sciences, Makerere University, has successfully determined the first-ever Diagnostic Reference Levels (DRLs) for adult Computed Tomography (CT) examinations in Uganda.
His comprehensive doctoral study, “Diagnostic Reference Levels for Adult Computed Tomography Examinations in Uganda EREM conducted a study to determine the first adult Diagnostic Reference Levels for Computed Tomography Examinations in Uganda,” employed both quantitative and qualitative approaches.
The study brings valuable insights that will contribute to the optimization of CT scan parameters across the country, setting a new standard for radiological procedures.
Dr. EREM’s research, culminating in the establishment of Diagnostic Reference Levels, represents a significant leap forward in the field of medical imaging.
DRLs serve as crucial benchmarks, guiding healthcare professionals in managing radiation exposure during CT scans.
His research addresses a critical need to enhance the safety and effectiveness of diagnostic procedures, ultimately benefiting patients across Uganda.
The study further delved into a comprehensive examination of various factors influencing CT examinations. Notably, patient characteristics, examination details, and the technical parameters of CT scans were scrutinized to establish a nuanced understanding of the relationship between these variables.
Findings
One of the key findings was the positive association between examination, reference, and total mAs (milliampere-seconds) with patient characteristics across different healthcare facilities. The meticulous analysis revealed insights into how these parameters interact, informing the development of tailored recommendations for optimal CT scan practices.
An intriguing aspect of the research was the examination of gender differences in CT scan characteristics. Males exhibited a higher association with exposure characteristics for head and cardiac CT scans, while females showed a significant relationship with parameters for abdominal CT scans.
These nuanced findings underscore the importance of considering gender-specific factors in optimizing radiation doses during CT examinations.
As a result, Dr. Erem’s work calls for the optimization of CT scan parameters. By establishing Diagnostic Reference Levels, the research aims to provide clear guidance for healthcare professionals, ensuring that CT scans are conducted with the highest quality and safety standards.
The study advocates for targeted training programs for CT scan radiographers, empowering them with the skills needed to optimize acquisition parameters effectively.
The research proposes regular dose audits for all new CT scan equipment in Uganda. A proposed timeframe of every three years aligns with international best practices and emphasizes the commitment to ongoing monitoring and adjustment of radiation doses.
Dr. EREM’s impactful work was made possible through the guidance of his esteemed supervisors: Prof. Michael Grace Kawooya from the Ernest Cook Ultrasound Research and Education Institute, Uganda; Dr. Akisophet Kisolo, Makerere University; and Prof. Cyril Schandorf, University of Ghana.
The collaborative efforts of the research team have not only advanced medical imaging practices but also paved the way for a transformative impact on patient care and diagnostics in Uganda.
