There are slightly different formats for the time-activity data of blood and tissue. With blood data it is assumed that instantaneous sampling was performed at well-defined time points. With tissue data it is assumed that the measurements represent the average tracer concentration during a certain observation period, the PET frame duration defined by start-time and end-time.
Data Units
Typically the data will arise in the following units:
The unit string in square brackets should immediately follow the column header. If units are not defined in the column headers or not recognized, it is assumed that the units specified in the PKIN configuration apply.
Note: During loading, the input unit specification will be used to convert the activity values into the internal representation of kBq/cc. All loaded data will be displayed with these values after conversion.
