Bolus Tracking

How to do it

To achieve optimal results in contrast studies, use of

CARE Bolus is recommended. In case it is not available,

use Test Bolus.

CARE Bolus

This is an automatic bolus tracking program, which

enables triggering of the spiral scanning at the optimal

phase of the contrast enhancement.

General Hints:

1. This mode can be applied in combination with

any spiral scanning protocol. Simply insert “Bolus

tracking” by clicking the right mouse button in

the chronicle. This inserts the entire set up including

pre-monitoring, i.v. bolus and monitoring scan

protocol. You can also save the entire set up as your

own scan protocols (please refer to page 20 “How

to Create your own Scan Protocols”).

2. The pre-monitoring scan is used to determine the

level of monitoring scans. It can be performed at

any level of interest. You can also increase the mAs

setting to reduce the image noise when necessary.

3. To achieve the shortest possible spiral start delay

(2 s), the position of the monitoring scans relative

to the beginning of spiral scan must be optimized.

A “snapping” function is provided:
