Specific Anatomic Region Bladder

Application Virtual cystoscopy to stage bladder cancer/ follow up bladder cancer.

Reference Source Personal Communication

Scanner Used Siemens Plus4 Volume Zoom

KV / mAs / Time per Rotation (sec) 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 N/A

IV Contrast Volume and Type 300-400 cc of dilute Omnipaque-350

Injection Rate See below

Scan Delay (sec) N/A

3D Technique Used Volume rendering w/endoscopy

Comment: The optimal study requires bladder distension, whether with water, air, or a dilute omnipaque solution. My best results are with positive contrast. The easiest technique is to inject 30 cc of omnipaque into a 500 ml bag of saline & drip it into the bladder under gravity.
