Personalized Protocols With Standardized Success


Personalized CT dosing software allows technologists to individually optimize contrast protocols at the point of care when using MEDRAD® smart injection systems.

Implementing personalized protocols allows you to:

  •     Facilitate implementation of multiple CT abdomen protocol strategies  
  •     Manage cardiac-imaging complexity  
  •     Enable improved protocol adherence

Our workstation helps technologists account for unique patient and study variables. Certegra® P3T personalized CT dosing software personalizes CT protocols for cardiac, pulmonary, and abdomen (liver, pancreas, and kidneys) studies.  

Specifically, Certegra® P3T 2.0 enables technologists to:

  • Preset radiologist-preferred dosing strategies, contrast concentrations, and scan timing  
  • Recall up to 250 stored protocols

Comparison of cardiac images and enhancement of coronary tree using P3T protocol versus standard injection protocol.  

Control Group 1 received 80 mL of CM at 6 mL/s.  

P3T Group injection parameters were individually adjusted to patient weight, the duration of CT data acquisition, and attenuation parameters following a test bolus.  

For Control Group 2, the volume of CM was adjusted to the duration of CT data acquisition and injected at 5 mL/s.
