“…The sensitivity ranges from 84% to 98% and the specificity ranges from 90% to 99%. [12][13][14][15][16][17][18][19][20][21][22][23] The sonographic Murphy's sign was chosen to be the focus of the BAU examination for acute cholecystitis because it is one of the most sensitive indicators of acute cholecystitis and is technically simple to elicit. The definition of the sonographic Murphy's (positive when the site of maximal tenderness corresponded to the location of the gallbladder determined by the US transducer) we used has been described in the radiologic literature.…”

“…Since 1974, the imaging capabilities of gray scale sonography have improved steadily, with corresponding increases in its accuracy in gallstone recognition. In 1974, Goldberg et al [1] reported an accuracy rate for positive diagnoses of 88%, and subsequent studies have reported between 84% and 100% accuracy [2][3][4][5][6][7][8][9]. These results compare favorably with the accuracy of gallstone diagnosis by both oral cholecystography and intravenous cholangiography [9][10][11].…”

Recent advances in the imaging capabilities of gray scale sonography have increased the accuracy with which gallstones may be diagnosed. Since the sonographic diagnosis of gallstones is often followed by surgery without further confirmatory studies, the avoidance of false-positive diagnoses assumes major importance. In an attempt to improve diagnostic accuracy, 420 gallbladder sonograms were evaluated for gallstones. Positive diagnoses were limited to cases in which the gallbladder was well visualized and contained densities that produced acoustic shadowing or moved rapidly with changes in position. Gallstones were diagnosed in 123 cases and surgery or autopsy in 70 of these patients confirmed stones in 69. There was one false-positive, an accuracy rate for positive diagnosis of 98.6%. Five cases were called indeterminate for stones; one of these had tiny 1 mm stones at surgery. The other four cases had no surgery. Of 276 cases called negative for stones, two were operated. One contained tiny 1 mm stones; the other had no stones. None of the 146 cases with negative sonograms and oral cholecystography or intravenous cholangiography had stones diagnosed by these methods. Because of its ease and simplicity, sonography is attractive as the initial study in patients suspected of having gallstones. With the criteria used here, a diagnosis of gallstones in the gallbladder can be offered with great confidence.

“…Bartrum et al [22] and Lutz et al [23] have reported the accuracy of stone detection in a visible gallbladder as 96%; Leopold etal. [24], 91%; Arnon and Rosenquist [25], 90% ; and Andersson and Harned [26], 89%. In our material 27 patients were verified as having cholelithiasis.…”

Infusion tomography and ultrasonography of the gallbladder in the diagnosis of acute cholecystitis

Sixty-three patients with the clinical suspicion of acute cholecystitis were examined with infusion tomography of the gallbladder. Ultrasonography was performed in 51 of these cases. The technique and diagnostic principles of both methods are discussed. The diagnostic value of the two methods when used in combination is stressed. Thus in a case of gangrenous cholecystitis when opacification of the gallbladder wall may not appear at infusion tomography, ultrasonography may demonstrate signs of gallbladder disease. Infusion tomography, on the other hand, may be of great value if ultrasonography is not informative.In acute cholecystitis there is reason to believe that surgical intervention should be carried out as early as possible in order to reduce mortality [1-4]. The need for rapid and reliable diagnostic methods is therefore obvious. If the patient has a history of repeated attacks of biliary colic and is admitted to the hospital with fever, pain, and tenderness localized in the right upper quadrant of the abdomen, the diagnosis of acute cholecystitis is likely, at least if earlier cholecystography has proved the presence of cholelithiasis and/or nonfunctioning gallbladder. In such instances, there is seldom need for further diagnostic considerations before operative intervention. However, many patients with acute cholecystitis have no history of abdominal pain and the clinical diagnosis is not firm enough to indicate an acute operation.
