(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.
