ioversol

Use 51%, 64%, 68%, and 74% for head and body imaging

Head Imaging
Note: After the intravenous infusion is finished, scan right away
51%: 100-250 mL (Infusion)
64%: 50-150 mL (Infusion)
68%: 50-150 mL (Infusion)
74%: 50-150 mL (Infusion)

Body Imaging
Note: The scanning interval varies depending on the indication and target organ.
51%: 35-100 mL (Bolus Injection) 70-250 mL (Infusion)
64%: 25-75 mL (Bolus Injection) 50-150 mL (Infusion)
68%: 320 25-75 mL (Bolus Injection) 50-150 mL (Infusion)
74%: 350 25-75 mL (Bolus Injection) 50-150 mL (Infusion)

fludeoxyglucose (18f)

Indicated for Positron emission tomography imaging:

Administer 5 to 10mCi intravenously

barium

Indicated for Computed Tomography
The concentration and volume of barium which is to be administered is generally based on degree and contrast required for examination and also on the equipment and the technique employed
For abdomen study purposes:
Administer 300 ml of CT barium suspension 30 min prior to the scan and 150 ml instantly before to scan
Or
Use it as suggested by the physician
For abdomen/pelvis study purposes:
Administer 450 ml of CT barium suspension 90 min prior to the scan and, 300 ml 30 min before to scan and after that, 150 ml instantly before to scan
Or
Use it as suggested by the physician

iotrolan

Administer dose of 1.0 to 2.0 mL/kg

bicisate dihydrochloride

Indicated for Single photon emission computerized tomography
The suggested dose for average individual (70 Kg) is 10 mCi to 30mCi (i.e., 370 MBq to 1110 MBq)

ioversol

Use 68% for Head and Body Imaging
1.5-2 mL/kg (range 1-3 mL/kg)

fludeoxyglucose (18f)

Indicated for Positron emission tomography imaging
:

Administer 2.6 mCi intravenously. There is no established optimum dosage adjustment for body size or weight

fludeoxyglucose (18f)

Indicated for Positron emission tomography imaging
:

Administer 2.6 mCi intravenously. There is no established optimum dosage adjustment for body size or weight

fludeoxyglucose (18f)

Indicated for Positron emission tomography imaging
:

Administer 2.6 mCi intravenously. There is no established optimum dosage adjustment for body size or weight

iopromide

Indicated for Contrast Computed Tomography
Above two years-300 mg/mL: Administer 1 to 2 mL/kg intravenously, ensuring that the cumulative dosage does not exceed 3 mL/kg
