Liver, gallbladder, pancreas, spleen and kidney color Doppler ultrasound do not need fasting

The liver, gallbladder and pancreas

color Doppler ultrasound usually need to be fasted before examination. The

spleen and kidney color Doppler ultrasound examination generally does not require a clear fasting state. However, if the examinee needs to check these five items at the same time, it is generally recommended to keep fasting to prevent eating from affecting the final examination results.

The examinee should fast and drink 6-8 hours before examination. People with food needs can eat properly after examination of liver, gallbladder and pancreas, and then perform spleen and kidney examination.
