System Overview The Intego™ PET Infusion System delivers
18
F-FDG or
18
F-NaF to patients during a PET or
PET/CT diagnostic procedure. In addition, the system provides effective radiation shielding to
medical personnel from
18
F radiation exposure during nuclear medicine diagnostic procedures.
The Intego™ PET Infusion System meets the following clinical needs:
1. For a typical 555 MBq (15 mCi) infusion per patient, it limits
18
F radiation exposure for
medical personnel to less than 60 μSv (6 mRem) finger dose and 3 μSv (0.3 mRem)
whole body dose.
2. Flexibility to program the required dose either by activity only or by activity per patient
weight.
3. Ability to deliver
18
F-RP within ±10% of the prescribed dose and within ±2% of the
measured dose, excluding Dose Calibrator calibration factor.
4. Capability to retain and print infusion history and dispensing records.
The Intego™ PET Infusion System is a self-contained, self-powered (available only on INT
SYS 200) mobile cart. A Multi-Dose Vial of RP (up to 27.75 GBq (750 mCi)) is stored within a
Shielded Chamber within the body of the system. A SAS is installed within the Shielded
Chamber at the same time a new Multi-Dose Vial of the RP indicated for use is installed. Just
prior to an infusion, the system measures a dose of RP along with a saline flush in the Dose
Calibrator. Once the correct radiation level is achieved, the RP dose and saline are infused into
the patient via a PAS. Rechargeable batteries provide sufficient power to keep the Dose
Calibrator warm so that the system can be unplugged and moved to a new location without
having to completely power Off.
The Intego™ PET Infusion System consists of the following:
1. RP Pump
2. Saline Pump
3. Dose Calibrator
4. Air Detector
5. System Shielding
6. Vial Shielding
NOTE: Radiation shielding performance is achieved by using the Vial Shield designed
by MEDRAD (or its equivalent).
