Ultrasound findings may show thickened gall bladder wall, tiny anechoic spaces (Rokitansky–Aschoff sinuses or RAS), and twinkling artifact (or comet-tail reverberation). Comet tail reverberation, which is due to reflections from cholesterol crystals, is a highly specific sign for adenomyomatosis. [8]
Adenomyomatosis describes a diseased state of the gallbladder in which the gallbladder wall is excessively thick, due to proliferation of subsurface cellular layer. It is characterized by deep folds into the muscularis propria. Ultrasonography may reveal the thickened gallbladder wall with intramural diverticulae, called Rokitansky-Aschoff sinuses.
In some cases, gallbladder wall thickening may be seen on ultrasound but is poorly defined and lacking specificity, particularly if the characteristic Rokitansky-Aschoff sinuses are not visualized. This can make it difficult to distinguish adenomyomatosis from other conditions that result in gallbladder wall thickening such as gallbladder cancer.
Abdominal ultrasound can be used to diagnose abnormalities in various internal organs, such as the kidneys, [1] liver, gallbladder, pancreas, spleen and abdominal aorta.If Doppler ultrasonography is added, the blood flow inside blood vessels can be evaluated as well (for example, to look for renal artery stenosis).
Postcholecystectomy syndrome (PCS) describes the presence of abdominal symptoms after a cholecystectomy (gallbladder removal). Symptoms occur in about 5 to 40 percent of patients who undergo cholecystectomy, [1] and can be transient, persistent or lifelong. [2] [3] The chronic condition is diagnosed in approximately 10% of postcholecystectomy ...

Cholescintigraphic scanning is a nuclear medicine procedure to evaluate the health and function of the gallbladder and biliary system. A radioactive tracer is injected through any accessible vein and then allowed to circulate to the liver and starts accumulating in the gall bladder which can take up to an hour.
The investigation is usually conducted after an ultrasonographic examination of the abdominal right upper quadrant for a patient presenting with abdominal pain.If the noninvasive ultrasound examination fails to demonstrate gallstones, or other obstruction to the gallbladder or biliary tree, in an attempt to establish a cause of right upper quadrant pain, a cholescintigraphic scan can be ...
