Specific Anatomic Region | Chest |
Application | Suspected pulmonary embolism |
Author | Fishman EK |
Reference Source | Personal communication |
Scanner Used | Siemens Somatom Plus 4 |
Injection Rate | 3 ml/sec |
Contrast Volume and Type | 120ml of Omnipaque 350 |
Area Scanned | Level above aortic arch through lung bases |
Scan Delay | 25 sec |
Length of Spiral (time) | 30-35 sec |
Slice Thickness | 3 mm |
Table Speed/Pitch | 5 mm/sec |
Reconstruction Interval | 2 mm |
3D Technique Used | Volume Rendering or MPR |
Comment: We will scan from the lung bases upward to take advantage of better patient cooperation with breathholding in this critical region. Recent work suggests that Visipaque may be valuable due to better opacification of smaller vessels. |
