CARA

CARA, or the Controlled Attenuation Parameter, is a non-invasive tool used to measure liver fat. It works by sending a small, harmless pulse of ultrasound into the liver and assessing how much the sound waves are dampened or attenuated. Higher attenuation indicates more fat in the liver, which can help detect conditions like fatty liver disease. CARA provides a quick, painless way for doctors to monitor liver health without the need for biopsies, making it a valuable and safe diagnostic method.
