Uncollimated gamma camera measurements at two metres to the patient provide a practical and statistically robust method for SeHCAT retention calculation

[75Se]tauroselcholic acid (SeHCAT) retention studies may be performed using a collimated or uncollimated (intrinsic) gamma camera, with trade-offs between counting sensitivity, collision risk, and stray source influence. In this work, we evaluate the uncertainty in SeHCAT studies performed in ‘outer room’ mode, where the patient sits or stands two metres away from the uncollimated camera face.
