Coronary computed tomography angiography (CCTA) has been recognised as a procedure for diagnosing atherosclerotic plaques. One method used to test the diagnostic accuracy of new technical developments on the CT scanner is post-mortem imaging.

An effective CLE should have regular educational audits to meet quality education standards. In Zambia, the enrolment numbers of undergraduate radiography students have increased despite limited clinical training sites and training resources. Nevertheless, no published educational audit has been conducted to provide baseline information to decision-makers. Most of the research studies on the quality of CLE in clinical education have been conducted from the viewpoint of radiography students. Therefore, this study aimed to audit the clinical training sites for undergraduate radiography students from the perspectives of Zambian radiography clinical educators.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Methods&lt;/h3&gt;&lt;div&gt;This educational audit was conducted using a quantitative study design from April to July 2024. Data were collected using an audit questionnaire developed based on the National Quality Clinical Learning Environment Audit Tool (NQCLEAT). The educational audit was limited to nationwide clinical training sites (&lt;em&gt;n&lt;/em&gt; = 40) of undergraduate radiography students. As per the aim of this study, each clinical educator (designated radiographer) completed one audit questionnaire at each clinical training site. The quantitative data was analysed using descriptive and inferential statistics. Qualitative data on recommendations for improvement of clinical training were analysed using content analysis and presented in a table.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Results&lt;/h3&gt;&lt;div&gt;Thirty-six responses were received from radiography clinical educators, representing 90 % of the clinical training sites. Three standards had high adherence: orientation of students, provision of feedback and assessments and achievement of clinical learning outcomes. On the other hand, two standards were not fully implemented in most training sites: demonstrating commitment by HEIs and supporting student supervision. Three main recommendations for improvement of radiography clinical training were the formal appointment of clinical educators (&lt;em&gt;n&lt;/em&gt; = 17;32.7 %), providing training to clinical educators (&lt;em&gt;n&lt;/em&gt; = 12;23.1%) and clinical education guidelines and teaching materials (&lt;em&gt;n&lt;/em&gt; = 12; 23.1 %).&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Conclusion&lt;/h3&gt;&lt;div&gt;This educational audit's findings revealed areas for improvement in the CLE.

Arksey O'Malley's and Levac's framework were used to inform the procedural steps for the scoping review.
