Table C.8.22-9. Enhanced PET Isotope Module Attributes

Attribute Name | Tag | Type | Attribute Description
--- | --- | --- | ---
Radiopharmaceutical Information Sequence | (0054,0016) | 1 | Sequence of Items that describe isotope information. One or more Items shall be included in this Sequence.
>Radiopharmaceutical Agent Number | (0018,9729) | 1 | Identifying number, unique within this SOP Instance, of the agent administered. Used to reference this particular agent from the Radiopharmaceutical Functional Group Macro. The number shall be 1 for the first Item and increase by 1 for each subsequent Item.
>Radionuclide Code Sequence | (0054,0300) | 1 | Sequence that identifies the radionuclide. Only a single Item shall be included in this Sequence.
>>Include Table 8.8-1 “Code Sequence Macro Attributes” | Baseline CID 4020 “PET Radionuclide”.
>Administration Route Code Sequence | (0054,0302) | 1 | Sequence that identifies the administration route of the radiopharmaceutical. Only a single Item shall be included in this Sequence.
>>Include Table 8.8-1 “Code Sequence Macro Attributes” | Baseline CID 11 “Route of Administration”.
>Radiopharmaceutical Volume | (0018,1071) | 3 | Volume of administered radiopharmaceutical in cubic cm.
>Radiopharmaceutical Start DateTime | (0018,1078) | 1 | Time of start of administration. The actual time of radiopharmaceutical administration to the patient for imaging purposes.
>Radiopharmaceutical Stop DateTime | (0018,1079) | 3 | Time of end of administration. The actual ending time of radiopharmaceutical administration to the patient for imaging purposes.
>Radionuclide Total Dose | (0018,1074) | 2 | The radiopharmaceutical dose administered to the patient measured in MegaBecquerels (MBq) at the Radiopharmaceutical Start DateTime (0018,1078).
>Radiopharmaceutical Administration Event UID | (0008,3012) | 3 | Unique identification of the administration of the radiopharmaceutical to the patient. ### Note The UID is the same Radiopharmaceutical Administration Event UID that is in the Radiopharmaceutical Radiation Dose Report.
>Radionuclide Half Life | (0018,1075) | 1 | The radionuclide half life, in seconds, that was used in the correction of this image.
>Radionuclide Positron Fraction | (0018,1076) | 1 | The radionuclide positron fraction (fraction of decays that are by positron emission) that was used in the correction of this image.
>Radiopharmaceutical Specific Activity | (0018,1077) | 3 | The activity per unit mass of the radiopharmaceutical, in Bq/micromole, at the Radiopharmaceutical Start DateTime (0018,1078).
>Radiopharmaceutical Code Sequence | (0054,0304) | 1 | Sequence that identifies the radiopharmaceutical. Only a single Item shall be included in this Sequence.
>>Include Table 8.8-1 “Code Sequence Macro Attributes” | Baseline CID 4021 “PET Radiopharmaceutical”.
