My abdominal u/c say; liver shows Inhomogeneous echotexture and gallbladder appear small. No focal mass is seen in liver. Is it hepatitis???

No Answer. This cannot determine if you have hepatitis. This requires a blood test for diagnosis.
Can't tell. The diagnosis of hepatitis is made with blood tests, not by ultrasound. There are many things that can cause an inhomogenous appearance to the liver. You should follow up with your gastroenterologist. Good luck.
