Personalized CT Contrast Dosing

Patient-specific contrast dosing software designed to help radiology teams achieve consistent diagnostic enhancement across exams.

Personalizing CT Contrast Dosing for Every Patient

Fixed CT contrast protocols may not account for important patient, exam and scanning factors that can influence contrast enhancement. Bayer's personalized contrast dosing software is designed to tailor dosing recommendations to each study, helping support greater consistency across CT exams.

Why Does Personalized Contrast Dosing Matter?

Image Quality
Consistency

Supports consistent diagnostic enhancement across departments, technologists and patient populations.

Reduced Manual
Calculation

Gives teams a structured approach to dosing, reducing dependence on individual judgement and supporting more consistent workflows.

Efficient Contrast Use

Helps optimize iodine delivery so contrast can be used more efficiently.

Tailored Dose Decisions

Applies ALARA principles to contrast without compromising diagnostic quality.

Automated Calculation of Personalized CT Contrast Dosing

P3T® (Personalized Patient Protocol Technology) Software enables personalized injection protocol calculations for abdomen, cardiac and pulmonary angiography exams and is currently available to customers using MEDRAD® Centargo and MEDRAD® Stellant FLEX CT Injection Systems.

P3T Software calculations can account for:

Patient characteristics that may influence contrast needs
Contrast concentration used for the exam
Radiologist-preferred dosing strategies, contrast concentrations and scan timing through functionality to preset, store and recall protocols

Case Studies

P3T Software for Cardiac CT Imaging

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.

P3T Software for Abdominal CT Imaging

The P3T abdomen application automatically adjusts contrast volume using an algorithm based on patient, procedure and prescribed physician parameters.

A New Way to Personalize Your CT Injections

Coming this fall, Smart Protocols is designed to automatically adjust contrast and injection parameters to each patient at the time of the exam based on individual characteristics like patient weight, contrast agent details and scanner kVp.
