Article Abstract
Background: The role of hepato-imino diacetic acid scan (HIDA) in the diagnosis of acute cholecystitis remains controversial when compared with the more commonly used abdominal ultrasound (AUS).
Methods: The diagnostic imaging workup of 1,217 patients who presented to the emergency department at a single hospital with acute abdominal pain and suspicion of acute cholecystitis was reviewed to calculate the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of AUS and HIDA.
Results: In patients undergoing both imaging modalities, HIDA had significantly higher sensitivity (90.7% vs 64.0%, P < .001) and specificity (71.4% vs 58.4%, P = .005) than AUS for the diagnosis of acute cholecystitis. Additionally, PPV and NPV of HIDA (56.2% and 95.0%, respectively) were higher than PPV and NPV of AUS (38.4% and 80.0%, respectively) when both imaging modalities were used for the same patient.
Conclusion: In adults with acute abdominal pain, HIDA significantly increases the accuracy of the correct diagnosis.
Background: The (99m) technetium-labelled hepato imino diacetic acid (HIDA) scan is widely used to evaluate patients with biliary colic with a normal trans-abdominal ultrasound scan. Most studies recommend cholecystectomy for patients with biliary dyskinesia, defined by gallbladder ejection fraction (GBEF) of less than 35-40% on HIDA scan. There are no recommendations regarding management of hyperkinetic gallbladder defined by GBEF of greater than 80% on HIDA scan.
Background: Despite the increasing use of fatty meal (FM) as a substitute for cholecystokinin (CCK) in pain reproduction during hepato-imino-diacetic acid (HIDA) scan in functional gallbladder disorder, there are no studies comparing the differences between CCK and FM. The present study was to compare the efficacy of FM in comparison of CCK in FGBD application.
Methods: Patients undergoing HIDA scans from August 2013 to May 2014 were divided into two groups: those undergoing CCK-stimulated HIDA scan versus FM-stimulated HIDA scan.

Background: Acute cholecystitis is one of the most common surgical problems, yet substantial debate remains over the utility of simple examination, abdominal ultrasound (AUS), or advanced imaging such as hepato-imino diacetic acid (HIDA) scan to support the diagnosis.
Materials And Methods: The preoperative diagnostic workup of patients who underwent cholecystectomy with histologically confirmed acute cholecystitis was reviewed to calculate the sensitivity of AUS, HIDA scan, or both. In addition, the sensitivity of the commonly described ultrasonographic findings was assessed.
Background: The (99m) technetium labelled hepato imino diacetic acid (HIDA) scan is widely used in the investigation of patients with typical biliary pain but whose trans-abdominal ultrasound scan (US) is normal. Although the standard measure by which the HIDA scan is deemed positive is the presence of an ejection fraction (EF) of <35% following provocation with cholecystokinin (CCK), there still remains debate as to the usefulness of this measure. The aim of this study was to compare the roles of EF and symptom provocation following CCK infusion in relation to the outcome following laparoscopic cholecystectomy (LC).
