Check the liver, gallbladder, pancreas and spleen specific ultrasound or CT examination is more accurate, mainly depends on the examination site to determine, check the gallbladder ultrasound is more accurate, check the pancreas CT is more accurate, check the liver as well as the spleen basically not much difference. 1. When examining the gallbladder, ultrasound can further observe the proliferation of the mucous membrane of the gallbladder wall structure, especially for gallbladder polyps, ultrasound has a clearer significance than CT. 2. When examining the pancreas, ultrasound will affect the normal tissue visualization because of the blockage of surrounding tissues and intestinal gases, which will be less affected and more accurate by CT. 3. Examination of the liver and spleen, both modes of examination can clearly show the specific tissue structure, there is no obvious difference in accuracy, but generally speaking, CT is more objective and can find smaller lesions in the liver. When doing the relevant clinical examination, attention must be paid to the combination of the main examination to determine the location of the lesion, under the guidance of the clinician to standardize the formulation of the examination program, part of the population need to be jointly examined.
