#### C.8.9.2 PET Isotope Module

Table C.8-61 contains IOD Attributes that describe a PET Isotope.

Table C.8-61. PET Isotope Module Attributes

Attribute Name | Tag | Type | Attribute Description
--- | --- | --- | ---
Radiopharmaceutical Information Sequence | (0054,0016) | 2 | Sequence of Items that describe isotope information. Zero or more Items shall be included in this Sequence.
>Radionuclide Code Sequence | (0054,0300) | 2 | Sequence that identifies the radionuclide. Zero or one Item shall be included in this Sequence.
>>Include Table 8.8-1 “Code Sequence Macro Attributes” | Baseline CID 4020 “PET Radionuclide”.
>Radiopharmaceutical Route | (0018,1070) | 3 | Route of administration.
>Administration Route Code Sequence | (0054,0302) | 3 | Sequence that identifies the administration route of the radiopharmaceutical. Only a single Item is permitted 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 Time | (0018,1072) | 3 | Time of start of administration. The actual time of radiopharmaceutical administration to the patient for imaging purposes, using the same time base as Series Time (0008,0031). The use of this Attribute is deprecated in favor of Radiopharmaceutical Start DateTime (0018,1078). ### Note The use of a time alone can cause confusion when the procedure spans midnight.
>Radiopharmaceutical Start DateTime | (0018,1078) | 3 | Date and time of start of administration. The actual date and time of radiopharmaceutical administration to the patient for imaging purposes, using the same time base as Series Time (0008,0031).
>Radiopharmaceutical Stop Time | (0018,1073) | 3 | Time of end of administration. The actual ending time of radiopharmaceutical administration to the patient for imaging purposes, using the same time base as Series Time (0008,0031). The use of this Attribute is deprecated in favor of Radiopharmaceutical Stop DateTime (0018,1079). ### Note The use of a time alone can cause confusion when the procedure spans midnight.
>Radiopharmaceutical Stop DateTime | (0018,1079) | 3 | Date and time of end of administration. The actual ending date and time of radiopharmaceutical administration to the patient for imaging purposes, using the same time base as Series Time (0008,0031).
>Radionuclide Total Dose | (0018,1074) | 3 | The radiopharmaceutical dose administered to the patient measured in Becquerels (Bq) at the Radiopharmaceutical Start Time (0018,1072). ### Note In other IODs, such as the NM IOD, this same attribute is specified in MegaBecquerels (MBq).
>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) | 3 | The radionuclide half life, in seconds, that was used in the correction of this image.
>Radionuclide Positron Fraction | (0018,1076) | 3 | 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 Time (0018,1072).
>Radiopharmaceutical | (0018,0031) | 3 | Name of the radiopharmaceutical.
>Radiopharmaceutical Code Sequence | (0054,0304) | 3 | Sequence that identifies the radiopharmaceutical. Only a single Item is permitted in this Sequence.
>>Include Table 8.8-1 “Code Sequence Macro Attributes” | Baseline CID 4021 “PET Radiopharmaceutical”.
Intervention Drug Information Sequence | (0018,0026) | 3 | Sequence of Items that describes the intervention drugs used. One or more Items are permitted in this Sequence.
>Intervention Drug Name | (0018,0034) | 3 | Name of the intervention drug.
>Intervention Drug Code Sequence | (0018,0029) | 3 | Sequence that identifies the intervention drug name. Only a single Item is permitted in this Sequence.
>>Include Table 8.8-1 “Code Sequence Macro Attributes” | Baseline CID 10 “Interventional Drug”.
>Intervention Drug Start Time | (0018,0035) | 3 | Time of administration of the intervention drug, using the same time base as for Series Time (0008,0031).
>Intervention Drug Stop Time | (0018,0027) | 3 | Time of completion of administration of the intervention drug, using the same time base as for Series Time (0008,0031).
>Intervention Drug Dose | (0018,0028) | 3 | Intervention drug dose, in mg.
