CT is us- Multidetector CT Protocols

Multidetector CT:
Pelvis:

Evaluate ovarian mass/cancer

Specific Anatomic Region Pelvis

Application Evaluate ovarian mass/cancer

Author Fishman EK

Reference Source Personal Communication

Scanner Used Siemens Plus4 Volume Zoom

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

Detector Collimation (mm) 2.5

Slice Thickness (mm) 5

Data Reconstruction Interval (mm) 5

Table Speed (mm per rotation) / Pitch 12.5 / 5

Oral Contrast 750-100 cc of 3% Hypaque

IV Contrast Volume and Type 120 cc of Omnipaque 350

Injection Rate 2-3 cc / sec

Scan Delay (sec) 50 sec

3D Technique Used N/A

Comments:

Rectal contrast may be helpful in select cases, especially if the oral contrast was not given early enough.

We are now doing dual phase studies (arterial venous phases) to try to determine more accurately the extent of disease.
