Focused assessment with sonography in trauma (commonly abbreviated as FAST) is a rapid bedside ultrasound examination performed by surgeons, emergency physicians, and paramedics as a screening test for blood around the heart (pericardial effusion) or abdominal organs (hemoperitoneum) after trauma.
Failure of gallbladder visualisation during oral cholecystography when abnormal liver function returns to normal, or there is mild to moderate liver disease, maybe due to extrahepatic (outside the liver) causes. [4] Oral cholecystography can have better sensitivity and specificity in diagnosing acute and chronic gallbladder disease than ultrasound.
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 ...
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).
The IVC has been largely replaced by other diagnostic procedures—by ERCP (endoscopic retrograde cholangiopancreatography), endoscopic ultrasound and, increasingly, by MRI cholangiography, none of which are affected by jaundice. It is sometimes used when ERCP is unsuccessful. [2]
Murphy's sign has a high sensitivity and negative predictive value, although the specificity is not high. [2] However, in the elderly the sensitivity is markedly lower; a negative Murphy's sign in an elderly person is not useful for ruling out cholecystitis if other tests and the clinical history suggest the diagnosis.
Biliary colic, also known as symptomatic cholelithiasis, a gallbladder attack or gallstone attack, is when a colic (sudden pain) occurs due to a gallstone temporarily blocking the cystic duct. [1] Typically, the pain is in the right upper part of the abdomen , and can be severe. [ 2 ]
A Sonographic Murphy sign is a finding when performing diagnostic medical sonography.It is different from the Murphy sign found on physical examination, but both signs are associated with cholecystitis [1] When the sonographer presses directly over the gallbladder, and the patient expresses pain, more than when the sonographer presses anywhere else, this is said to be a positive sonographic ...
