PHA Analysis™

Rapid, Automated Evaluation of Right Ventricular Dilation

PHA™(Pulmonary Hypertension Assessment)is a cutting-edge, fully-automated imaging solution designed to help physicians swiftly assess potential right ventricular dilation—a key indicator of pulmonary hypertension. By automatically processing CTPA scans, PHA measures the maximal diameters of both the right and left ventricles and calculates theRV/LV ratio.The solution generates clear, annotated images highlighting ventricular measurements and delivers a concise summary report with the RV/LV ratio directly to the patient study inPACS. This streamlined workflow enables clinicians to quickly access critical information, supporting timely, confident decision-making in the assessment and management of pulmonary hypertension.

Physician Summary Report
Report includes patient study information and provides RV/LV ratios along with absolute maximum diameter measurements. It also reports the main pulmonary artery to aorta ratio. Additionally, key slice visuals are provided for each ventricle, clearly indicating the specific maximum diameter slices.

For Your Practice

PHA™

Aiding PE Response Teams (PERT). 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 PE34  and is supported by the American College of Radiology1 and the European Society of Cardiology Guidelines5 for certain patients dependent on additional clinical factors.
