Virtual colonoscopy can detect colorectal cancer (CRC) but faces challenges with small lesions. Radiation dose reduction is crucial for its acceptance as a screening tool.

Area of Science:

  • Radiology
  • Oncology
  • Medical Imaging

Background:

  • Virtual colonoscopy (VC) shows potential for early colorectal cancer (CRC) detection.
  • Accuracy and radiation exposure remain key discussion points in the radiological community.

Purpose of the Study:

  • To evaluate the efficacy of virtual colonoscopy for early detection of colorectal cancer.
  • To address concerns regarding accuracy and radiation exposure in VC.

Main Methods:

  • Utilized multislice CT and single slice CT for VC.
  • Employed special post-processing filters to reduce radiation dose.
  • Measured effective dose exposure using an Alderson phantom.

Main Results:

  • VC can detect relevant pathologies for early CRC detection.

  • Diagnosis of small lesions (<7 mm) remains challenging, similar to conventional colonoscopy.
  • Reduced tube current (20 mAs) achieved sufficient accuracy with an effective dose of 1.2 mSv.

    • Conclusions:

    • Virtual colonoscopy is a viable option for high-risk patients refusing conventional methods.
    • Further advancements in dose reduction, automated 3D reconstruction, and complete mucosal visualization are needed for widespread screening acceptance.
