coronary angioplasty: injection of contrast mediumThe right coronary artery is injected with radiopaque dye through a catheter in the aorta during a coronary angioplasty procedure.
A micturating cystogram (voiding cystourethrogram [VCUG]) involves the injection of contrast substance into the bladder and is of importance in the investigation of urinary tract infection in childhood.
METHODS: Rats underwent equal pressure pancreatic ductal injection of contrast solutions at varying pH with or without RTX.
All patients were examined with 3-mm-collimation CT before and after intravenous injection of contrast material.
However, CT angiography requires an injection of contrast material, delivers more radiation than calcium scoring and is more expensive.
At first, prior to intravenous injection of contrast agent, simple observation was performed for 20 min.
An arterial phase can be programmed empirically 15 20 s after the injection of contrast material.
For a definite conclusion, additional investigations, such as injection of contrast material or scintigraphy, are needed.
Typically, this second procedure is performed 10-20 min after the first injection of contrast agent.
Figure 2 The cyst showed contrast enhancement following postoperative injection of contrast medium into B4.
The portal venous phase was obtained 70 s after the initiation of intravenous injection of contrast agent.
