[Gray-scale ultrasound B-scanning in case of cholelithiasis, especially with negative cholecystoradiogram (author's transl)].
Report on the accuracy of gray-scale B-scanning concerning cholelithiasis. In 37 cases out of 43 examined patients sonographical results could be compared to operative and radiological results. In the case of 20 patients with a negative cholecystangiogram the results of sonography could be compared to operative results. Sonographically the gallbladder was shown in 89% of the cases. Gallstones were diagnosed at a high percentage (sensitivity 80%, specificity 88%). There were 20% false-negative diagnoses and 13% false-positive diagnoses.
