Review procedure precautions and adverse reactions prior to administration. Excretory urography: >14yrs: 30–60mL IV. Cerebral angiography: Carotid or vertebral angiography: single rapid inj of 6–10mL; Retrograde brachial cerebral angiography: single rapid inj of 35–50mL into the right brachial artery. Peripheral arteriography or venography: a single rapid inj of 20–40mL. Arthrography: Inject into joint. Knee, hip: 5–15mL; Shoulder, ankle: 5–10mL; Other: 1–4mL. Direct cholangiography: Operative: usual dose is 10mL but as much as 25mL may be needed depending upon the caliber of the ducts; Postoperative: injection usually made through an in-place T-tube; dose same as for operative cholangiography; Percutaneous transhepatic choliangiography: 20–40mL is generally sufficient to opacity the entire ductal system. Endoscopic retrograde cholangiopancreatography: inject slowly under fluoroscopic control; usual range: 10–100mL for visualization of common bile duct; 2–10mL for visualization of pancreatic duct. Contrast enhancement of CT brain imaging: 2mL/kg IV; max total dose 150mL. Cranial computerized angiotomography: 0.5–1mL/kg by bolus inj; max total dose per procedure 200mL. Contrast enhancement in body computed tomography: Vascular opacification: a bolus inj of 25–50mL may be used; repeat as necessary. IV digital subtraction angiography: may be injected centrally into superior vena cava or peripherally into an appropriate arm vein. Usual dose range: 20–40mL; inj may be repeated as necessary. Arterial digital subtraction angiography: usual doses: carotid or vertebral arteries: 3–8mL; Aortic arch: 15–25mL; Subclavian and brachial arteries: 5–15mL; Major branches of the aorta: 5–20mL; Lumbar aorta (bifurcation): 10–25mL.
