Specific Anatomic Region | Kidney |
Application | Suspected renal mass |
Author | Fishman EK, Urban, BA |
Reference Source | Spiral CT Evaluation of the Kidney (in: Spiral CT: Principles, Techniques and Clinical Applications. Fishman, Jeffrey, eds. 1998) |
Scanner Used | Siemens Somatom Plus 4 |
Injection Rate | 3cc/sec |
Contrast Volume and Type | 120cc Omnipaque 350 |
Area Scanned | From 2cm above to 2cm below kidneys |
Scan Delay (2 delays if dual spiral) | 30sec/70 sec (dual spiral) |
Length of Spiral (time) | 30-40sec each |
Slice Thickness | 3-5mm |
Table Speed/Pitch | 3-5mm |
Reconstruction Interval | 2- 3mm |
3D Technique Used | Volume rendering |
Comment: A few noncontrast scans (5mm) are obtained prior to injecting contrast. The key to an accurate evaluation of a renal mass is imaging in several different phases to look at the enhancement pattern and lesion borders. |
