Acquisition
|
Scanner: DiscoveryTM CT750 HD
CT acquisition:
-
kV/mA: 100/650
-
Coverage 140 mm
-
Recon: HD & ASIR
-
Dose: 2.1 mSv (with 10 ms padding)
-
BMI 24.5
|
|
Contrast injection parameters:
Change 3-phase injection: 80 ml of iodine contrast at 5 cc/sec then 30 ml of iodine/flush at 4.5 cc/s and 30 ml of saline flush at 3.5 cc/sec
|
Conclusion
|
In this case, the CT750 HD image quality helped us with our assessment of plaque and provided good accuracy on stenosis quantification.
