Pulmonary Hypertension Assessment (PHA™)

Rapid, fully-automated assessment of potential right ventricular dilation

Pulmonary Hypertension Assessment (PHA™) helps physicians quickly assess potential ventricular dilation by automatically processing CTPA scans to measure the maximal diameters of the right and left ventricles of the heart, and reporting the resulting RV/LV ratio. PHA provides annotated images showing the ventricular measurements and a summary report of the RV/LV ratio, automatically delivered to the patient study in PACS.

The Power of Personalized Quantitative Imaging

Standardize an often variable read and make it scalable for all CTA’s.

For Your Practice

Aiding PE Response Teams (PERT). Imbio Pulmonary Hypertension Assessment (PHA) provides fully-automated results from CTPA scans with the calculated RV/LV ratio and annotated images added to the patient study in your PACS.

CTPA remains the dominant form of imaging used in assessment of patients with suspect PE1,2  and is supported by the American College of Radiology1 and the European Society of Cardiology Guidelines3 for certain patients dependent on additional clinical factors.
