title: Shift in imaging modalities of gastrointestinal tract through 25 years and its impact on patient ionizing radiation doses.
abstract: We wanted to explore the shift in modalities when diagnosing the gastrointestinal tract through the last three decades and see how this has influenced on the radiation doses given to this patient population. Activity reports from a central hospital in the years of 1979-2003 have been reviewed. The x-ray based modalities have decreased, while there has been a marked increase in colonoscopies, gastroscopies, ultrasound, and magnetic resonance cholangiopancreatography. This has caused a reduction in collective effective radiation dose of 54%.
