[External compression and the appearance of calcification in gastric x-rays and abdominal echography].
To enhance the efficacy of abdominal echography, 3,970 people at high risk have been chosen from a mass screening of the stomach since may 1980. 942 individuals with 1,057 lesions including 22 primary malignancies of the liver, gallbladder, pancreas, and ren were found. Of the four were detected in the operable stages. To detected malignancies in their early (curable) stages, those examines at low risk should be more aggressively pursued, despite the tendency for the relative rate of detection to decline.
