Multidetector CT:
Vascular:

Renal arteries: Renal artery stenosis evaluation

Specific Anatomic Region Renal arteries

Application Renal artery stenosis evaluation

Author Fishman EK

Reference Source Personal Communication

Scanner Used Siemens Plus4 Volume Zoom

KV / mAs / Time per Rotation (sec) 120 / 130 / .5 or 120 / 165 / .5

Detector Collimation (mm) 1

Slice Thickness (mm) 1.25

Data Reconstruction Interval (mm) 1

Table Speed (mm per rotation) / Pitch 6 / 6

Oral Contrast 750 cc of water

IV Contrast Volume and Type 100-120 cc of Omnipaque 350

Injection Rate 3 cc / sec

Scan Delay (sec) 25 sec

3D Technique Used Volume rendering

Comment: -A potentially even better protocol that we will begin looking at is using .5 mm detector, and a slice thickness of .5 mm, and reconstructing at .5 mm. Scan parameters 120/130/.5.
