CAP™

A tool for non invasive assessment and quantification of steatosis.

What is CAP™?

CAP™ is a measure of the ultrasound attenuation which corresponds to the decrease in amplitude of ultrasound waves as they propagate through the liver.

CAP™ is powered by a sophisticated guidance process based on VCTE™ that ensures that:

-CAP™ and liver stiffness are simultaneously measured in the same liver volume

-CAP™ is calculated only if liver stiffness measurement is valid

CAP™ is measured with the M probe at 3.5 MHz at depth between 25 and 65 mm
CAP™ is expressed in decibel per meter (dB/m)

CAP™ measurement

Like for liver stiffness measurement with the FibroScan®, CAP™ measurement:

-is non invasive

-is immediate: does not lengthen the FibroScan® examination

-benefits from an established examination procedure: the final CAP™ result is the median of at least 10 valid CAP™ measurements

-can be performed by an operator without any ultrasound imaging skills

CAP™ is a tool for non invasive assessment and quantification of steatosis enhancing the spectrum of non invasive methods for the examination and follow-up of patients with liver disease.
