#### C.7.6.4 Contrast/Bolus Module

Table C.7-12 specifies the Attributes that describe the contrast /bolus used in the acquisition of the Image.

Table C.7-12. Contrast/Bolus Module Attributes

Attribute Name | Tag | Type | Attribute Description
--- | --- | --- | ---
Contrast/Bolus Agent | (0018,0010) | 2 | Contrast or bolus agent
Contrast/Bolus Agent Sequence | (0018,0012) | 3 | Sequence that identifies the contrast agent. One or more Items are permitted in this sequence.
>Include Table 8.8-1 “Code Sequence Macro Attributes” | Baseline CID 12 “Radiographic Contrast Agent”.
Contrast/Bolus Route | (0018,1040) | 3 | Administration route of contrast agent
Contrast/Bolus Administration Route Sequence | (0018,0014) | 3 | Sequence that identifies the route of administration of contrast agent. Only a single Item is permitted in this sequence.
>Include Table 8.8-1 “Code Sequence Macro Attributes” | Baseline CID 11 “Route of Administration”.
>Additional Drug Sequence | (0018,002A) | 3 | Sequence that identifies any additional drug that is administered with the contrast agent bolus. One or more Items are permitted in this sequence.
>>Include Table 8.8-1 “Code Sequence Macro Attributes” | No Baseline CID is defined.
Contrast/Bolus Volume | (0018,1041) | 3 | Volume injected in milliliters of diluted contrast agent
Contrast/Bolus Start Time | (0018,1042) | 3 | Time of start of injection
Contrast/Bolus Stop Time | (0018,1043) | 3 | Time of end of contrast injection
Contrast/Bolus Total Dose | (0018,1044) | 3 | Total amount in milliliters of the undiluted contrast agent
Contrast Flow Rate | (0018,1046) | 3 | Rate(s) of injection(s) in milliliters/sec
Contrast Flow Duration | (0018,1047) | 3 | Duration(s) of injection(s) in seconds. Each Contrast Flow Duration value shall correspond to a value of Contrast Flow Rate (0018,1046).
Contrast/Bolus Ingredient | (0018,1048) | 3 | Active ingredient of agent. Defined Terms: IODINE GADOLINIUM CARBON DIOXIDE BARIUM
Contrast/Bolus Ingredient Concentration | (0018,1049) | 3 | Milligrams of active ingredient per milliliter of (diluted) agent

### Note

1. Flow duration is an alternate method of specifying stop time

2. Flow rate allows for stepped injections by being capable of multiple values (1,N) instances.

3. For a 100 ml injection of 76% Diatrizoate and meglumine/sodium, diluted 1:1,

   - the Contrast/Bolus Agent would be "76% Diatrizoate" as text

   - the Contrast/Bolus Volume would be 100 ml,

   - the Contrast/Bolus Total Dose would be 50 ml,

   - the Contrast/Bolus Ingredient would be "IODINE",

   - the Contrast/Bolus Ingredient Concentration would be 370mg/ml.
