Magnetic resonance (MR) colonography with fecal tagging is a preferred and less time-consuming alternative to conventional colonoscopy for patients. This method offers a more comfortable examination experience.

Area of Science:

  • Medical Imaging
  • Gastroenterology

Background:

  • Magnetic resonance colonography (MRC) is a promising colon examination technique but currently available only in specialized centers.
  • Implementation of MRC with fecal tagging aims to broaden its accessibility.

Purpose of the Study:

  • To describe the implementation of MR colonography (MRC) utilizing fecal tagging.
  • To evaluate patient preference and experience compared to conventional colonoscopy (CC).

Main Methods:

  • Patients undergoing conventional colonoscopy (CC) were offered MR colonography (MRC) with fecal tagging prior to CC.
  • An oral contrast agent was administered two days before MRC.
  • Patients completed questionnaires regarding their experience, and MR images were assessed by a blinded investigator.

Main Results:

  • Over six months, 30 patients were included. The median MRC examination time was 23 minutes, and evaluation time was 9 minutes.
  • Sixty-six percent of patients preferred MRC over CC for future examinations.
  • Barium sulfate with ferumoxsil was identified as a superior oral contrast agent compared to barium sulfate alone.

Conclusions:

  • A majority of patients found MRC less unpleasant and preferred it over CC for future colon examinations.
  • MRC appears to be less time-consuming for both patients and medical staff compared to CC, including post-procedural monitoring.
