Overview
75SeHCAT testing may be helpful in the diagnosis of IBS patients with bile acid diarrhea. The 75SeHCAT test measures the whole-body retention of 75Se-homocholyltaurine, a bile acid radiolabeled with the gamma-emitting isotope selenium-75. Retention of the isotope is measured by gamma-camera scanning performed a week after administration.
Other Imaging Findings
75SeHCAT test
- IBS patients with diarrhea sometimes have bile acid diarrhea on 23-seleno-25-homotaurocholic acid (75SeHCAT) testing.[1]
- The 75SeHCAT test measures the whole-body retention of 75Se-homocholyltaurine, a bile acid radiolabeled with the gamma-emitting isotope selenium-75.
- Retention of the isotope is measured by gamma-camera scanning performed a week after administration.[2][3]
