How to diagnose hyperechoic formation?
Ultrasound is the main method of diagnosing hyperechoic formation. The first thing that needs to be done when identifying such a seal is to determine the nature of its occurrence. Particular attention is paid to the general condition of the body and the accompanying symptoms. Additional diagnostic procedures depend on the location of the inclusions.

What is the main component of gallstones?
Cholesterol is the main component in approximately 80% of gallstones, with 10% being pure cholesterol. Pigment stones have by definition less than 25% cholesterol, and the major component is calcium bilirubinate. Calcium carbonate is a less common constituent (, 5 ).
Why do gallstones increase with age?
The prevalence increases with age in both sexes. In brief, the pathogenesis of gallstones is related to supersaturation of bile constituents, most notably cholesterol, and likely related to defects in biliary lipid metabolism. Biliary dysmotility and prolonged intestinal transit also likely play a role (, 2,, 3 ).

Further complications of cholelithiasis include pancreatitis (,,, Fig 16 ), duodenitis (,,, Fig 17 ), biliary fistula (, Fig 18 ), gallstone ileus (,,, Fig 19 ), and Mirizzi syndrome, in which inflammation related to a stone impacted in the cystic duct causes narrowing of the CBD and subsequent biliary obstruction.
Why is oral cholecystography limited?

What is the best method of detecting gallstones?
Ultrasonography (US) is the method of choice for detection of gallstones. The characteristic US findings of gallstones are a highly reflective echo from the anterior surface of the gallstone, mobility of the gallstone on repositioning the patient, and marked posterior acoustic shadowing.
When was cholecystography first used?
Oral cholecystography was introduced in 1924 and remained the mainstay of radiographic diagnosis of gallbladder disease for decades. Although still used, oral cholecystography has largely been replaced by ultrasonography (US) for evaluation of cholelithiasis and its associated complications, most notably acute cholecystitis.
