9.2.1 Fluid Detection Methods

The Stellant syringe aids in determining the presence of fluid by using two methods:
9.2.1.1 Using MEDRAD
NOTE: If using the optional heat maintainer, ensure that the heat maintainer is positioned in such a
FluiDots should be observed as part of an arming procedure. When the FluiDots are viewed through an
empty syringe, the dots appear as small, narrow ellipses, as illustrated in Figure 9 - 3: FluiDots. When
viewed through a full syringe, the dots become larger, almost round.
• Follow aseptic technique when handling disposable components. Specifically, maintain
sterility of all disposable components.
• Do not disassemble any disposable components.
• Visually inspect contents and package before each use.
• Syringes are not intended to be used as storage containers. Do not use syringes to
store fluids.
• Use only disposables supplied by Bayer. Refer to
• Use only syringes and tubing with a pressure rating greater than the maximum
programmable pressure limit of the injection system, which is 325 psi (2241 kPa).
• Use catheters with pressure ratings compatible with this system. Refer to
Flow Rate Performance"
• Check the patient history for any evidence of allergy to injectable fluid sources.
• Programming or loading an incorrect fluid source or concentration may result in patient
injury or suboptimal imaging.
• Use catheters and connectors with pressure ratings compatible with this system. Refer to
"Maximum Flow Rate Performance"
• Ensure the syringe is properly snapped into the front of the injector head before injecting.
Improper engagement or rotating syringe may cause the syringe to leak, to become
damaged, or to come off during the injection, and result in an under-volume delivery and
the syringe becoming a flying projectile.
• The use of clear material allows visual detection of air inside of the syringe.

• MEDRAD FluiDots on the syringe's wall appear round when the syringe is full of fluid and
oval when the syringe is empty.
