Procedure. There are many methods for measuring body temperature. The most common method is oral temperature. The thermometer must be placed beneath the tongue to one side and the lips must be closed around it tightly. Allow it to remain inside for the necessary period of time. Remove and then read the measurement.
During a HIDA Scan a scanner monitors the radioisotope that was initially injected. When (CCK) cholecystokinin, a hormone that's normally released by the body after a meal, is injected, the contraction of the gallbladder is identified on the scan. Reduced contraction (which often produces pain) may mean anything from actual gallbladder disease/dysfunction, to inflammation or scarring.
Once the HIDA scan dye was in, the technician moved the table under a machine which he positioned over my liver area. The machine took a series of photos (one photo took a full five minutes) over the next 20 minutes, and then I was asked to go and sit in a waiting area for 15 - 20 minutes.
