A critical appraisal of the unmet needs for cross-sectional imaging techniques in Nigeria

Nigeria faces a significant gap in access to cross-sectional imaging techniques such as Computed Tomography (CT) and Magnetic Resonance Imaging (MRI), which are critical for accurate disease diagnosis and management. This review critically examines the unmet needs for these imaging technologies in Nigeria by evaluating peer-reviewed articles, case studies, and national healthcare reports. The review focuses on identifying barriers to access, including infrastructural deficits, lack of trained personnel, and financial constraints that hinder the widespread adoption of CT and MRI in Nigerian healthcare. A comprehensive literature search from 2000-2024 was conducted using various databases and keywords, such as “cross-sectional imaging”, “Nigeria healthcare”, and “CT and MRI accessibility”. The findings underscore the diagnostic and clinical benefits of these imaging modalities, particularly in managing non-communicable diseases and trauma cases, which are on the rise in Nigeria. However, despite technological advancements, the cost and availability of equipment remain limiting factors. This review highlights the need for policy reforms, investments in medical infrastructure, and workforce training to address the growing demand for cross-sectional imaging. Future research should focus on developing cost-effective models and public-private partnerships to bridge the gap, ultimately enhancing patient outcomes and improving healthcare delivery across Nigeria.
