CT colonography training for radiographers--a formal evaluation.

Area of Science:

• Medical Imaging
• Radiography
• Gastrointestinal Imaging

Background:

• Computed Tomography Colonography (CTC) requires specialized radiographer skills for technique and interpretation.
• Patient triage in CTC necessitates accurate image analysis and procedural competence.
• Variability in CTC performance between centers can impact patient care.

Purpose of the Study:

• To assess the effectiveness of an intensive, hands-on training course for radiographers in CTC.
• To evaluate improvements in CTC technique, image interpretation, and patient triage skills.
• To determine if the training course enhances diagnostic accuracy for colorectal pathologies.

Main Methods:

• A structured, small-group "hands-on" course combining lectures and practical training in CTC.
• Radiographer knowledge assessed via pre/post-course multiple-choice questions (MCQ).
• Practical skills evaluated using checklists and global scores; interpretation performance by pre/post-course test datasets.

Main Results:

• Significant improvements in MCQ scores (59% to 69%, p<0.001) and interpretation accuracy (55% to 71%, p<0.001).
• Detection rates for cancer and large polyps (>10mm) increased significantly (49% to 60%, p=0.002).
• High practical skills observed, with mean checklist scores of 14/15 and global scores of 26/30.

Conclusions:

• Structured CTC training effectively enhances radiographer knowledge and interpretation skills.
• The course ensures safe procedural performance and improves diagnostic accuracy.
• National implementation of such programs could standardize CTC performance and reduce disparities.
