Area of Science:
- Medical Imaging
- Gastroenterology
- Radiology
Background:
- CT colonography is a valuable tool for colorectal examination.
- Ensuring high-quality examinations is essential for accurate diagnosis.
Purpose of the Study:
- To detail the essential technical aspects of CT colonography.
- To highlight requirements for optimal examination quality and application.
Main Methods:
- Fecal tagging for patient preparation.
- Adequate colon distension using carbon dioxide (CO2).
- Supine and prone data acquisition with thin-slice, low-dose protocols.
Main Results:
- The described technique ensures a high-quality CT colonography examination.
- Adherence to technical aspects is vital for accurate ascertainment of findings.
- The technique supports far-reaching applications of CT colonography.
