Thus, the main goal for MSCT coronary angiography in the near future must be to further reduce radiation exposure for instance by tube current modulation [32], [33] or prospectively triggered scanning using 256-slice CT [34] to reduce the cancer-inducing risk of this examination and thus make the test more acceptable to patients.
Respiratory triggered scanning improves SNR, but at the expense of an approximately threefold increase in scanning time.
Despite the above-mentioned breakthroughs in DWI, breathhold or respiratory triggered scanning was still considered necessary since it was widely accepted that respiratory motion was an impediment for DWI of (moving) visceral organs [ 11– 15].
> -wrap-foot> aFor imaging of the upper abdomen (including liver, spleen, and pancreas), a b-value of 500 s/mm can be applied, if necessary combined with respiratory triggered scanning bFor tumor detection in the prostate, b-values in the order of 1,500 2,000 s/mm can be applied Primary tumors and distant metastases exhibiting restricted diffusion can be identified with DWIBS.
In fluoroscopic triggering, the full bolus of contrast is administered and fluoroscopic-like images of the area of interest are obtained, and when the bolus is detected within the vessel, the technologist can trigger scan acquisition.
A real-time bolus tracking method was used to trigger scan initiation.
The combination of symptoms suggestive of NET and increased Cg-A level should trigger scanning with a radiolabelled SSA, even in the absence of abnormality on structural imaging.
As well as dodgy links, it can also be triggered by scanning a malicious QR code.
Each analysis segment contains a full scan from m/ z 650 to 1800 (scan event 1) followed by four data-dependent scans triggered by the four most abundant precursors from scan event 1 (scan events 2 5).
Triggering the scan will vary accordingly.
When a cell change is expected, it triggers active scan to find new coordinator.
