Two-dimensional (2D) analysis and automated 3D virtual navigation offer comparable time efficiency for CT colonography interpretation. Manual 3D navigation was less time-efficient, with no differences in diagnostic accuracy across methods.

Area of Science:

  • Radiology
  • Medical Imaging
  • Gastroenterology

Background:

  • CT colonography (CTC) is a minimally invasive colorectal cancer screening tool.
  • Efficient interpretation of CTC is crucial for widespread clinical adoption.
  • Different visualization methods, including 2D and virtual endoscopy (VE), exist for CTC analysis.

Purpose of the Study:

  • To compare the time efficiency of three distinct visualization methods in CT colonography.
  • To identify colonic factors that influence interpretation time during CTC analysis.

Main Methods:

  • Prospective analysis of twenty CT colonographic examinations.
  • Three reading methods were evaluated: primary 2D with VE as problem solver (Method 1), primary VE with semi-automatic navigation and 2D as problem solver (Method 2), and primary VE with automatic navigation and 2D as problem solver (Method 3).

  • Interpretation times for each method were recorded and statistically compared.

    • Main Results:

    • Method 1 (2D primary) mean interpretation time was 12 minutes; Method 2 (semi-automatic 3D VE) was 17 minutes; Method 3 (automatic 3D VE) was 12 minutes.
    • A statistically significant difference in time efficiency was found between Method 1 and Method 2 (p=0.009).
    • Methods 2 and 3 showed a tendency towards significant differences (p=0.054). Faecal/fluid residuals impacted 3D navigation, while tortuous folds affected 2D analysis; diverticula influenced all methods. No differences in sensitivity or specificity were observed.

    Conclusions:

    • 2D analysis and automated 3D virtual navigation demonstrate comparable time efficiencies in routine clinical settings.
    • Primary 2D analysis is significantly more time-efficient than primary semi-automatic 3D virtual navigation.
    • Semi-automatic 3D navigation tended to increase interpretation time, with no improvement in diagnostic accuracy.
