CT is us- Multidetector CT Protocols

Multidetector CT:
Chest:

Lung mass: R/O AVM; evaluate AVM

Specific Anatomic Region Lung mass

Application R/O AVM; evaluate AVM

Author Fishman EK

Reference Source Personal Communication

Scanner Used Siemens Plus4 Volume Zoom

KV / mAs / Time per Rotation (sec) 140 / 100 / .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 N/A

IV Contrast Volume and Type 120 cc of Omnipaque 350

Injection Rate 3 cc / sec

Scan Delay (sec) 30 sec

3D Technique Used Volume rendering

Comment: -3D volume rendering is ideal to detect the presence of an AVM as well as define its feeding and draining vessels. Axial images alone are not enough in these cases.
