Background: Real-time ultrasound scanning is increasing in popularity as a teaching tool for human anatomy because it is non-invasive, offers real-time 3-D anatomy and is cheaper than dissections.
Objectives: To assess real-time ultrasound scanning as a teaching method of human anatomy, and to determine what teaching methods radiography students consider effective for understanding human anatomy.
Materials and methods: One hundred and ten self-administered, structured and pre-tested questionnaires were distributed to Clinical Radiography students (Third, fourth and fifth year)in Northern Nigeria featuring University of Maiduguri and Bayero University Kano. The questionnaire consists of two sections;Demographics and preferred methods of delivery of anatomical information. Participation was voluntary. Comparisons among teaching methods were made using repeated measures ANOVA.
Results: A significant difference among the eight delivery methods with 3-D Radiology imaging being as the most preferred method overall (48.17, p<0.0001) and ultrasound the least (32.48, p<0.0001). With Duncan’s multiple Range test, it is clearly shown that 3-D Radiology imaging differ with mean value(5.2522) followed by Computer programs(5.1292), Anatomic models(4.7593), Laboratory videos(4.5815), textbooks(4.5358), animal dissection(4.2568), lectures(3.2568) and finally ultrasound scan (3.6087), (P<0.0001).
Conclusion: 3-D Radiology imaging is the most preferred method of delivering anatomical information and ultrasound scanning is the least preferred method.
