Hepatobiliary scintigraphy is primarily used to diagnose acute and chronic biliary tract disorders. However, its potential role in diagnosing unsuspected extrahepatic pathology is not well described. We present 2 adult patients with chronic abdominal pain who underwent hepatobiliary scintigraphy for evaluation of cystic duct patency. In both cases, the proximal small bowel was located on the right side of the abdomen, which suggested the diagnosis of malrotation. Retrospective review of abdominal CT scan, upper gastrointestinal series, and subsequent laparotomy confirmed malrotation. The diagnosis of malrotation in both these patients was first suggested on hepatobiliary scintigraphy, which significantly impacted their subsequent management.

For hepatobiliary scintigraphy, the radiopharmaceutical drug, ETIFENIN (TECHIDA®), labelled with technetium-99m, is used as a substitute for MEBROFENIN (CHOLEDIAM®). It is generally accepted that radiopharmaceuticals should be checked prior to injection, in particular by determining radiochemical purity, to ensure high-quality images. Radiochromatographic techniques or methods described in the Summary of Product Characteristics (SmPC) and the European Pharmacopeia (Ph.

Background: To study the feasibility of hepatobiliary scintigraphy (HBS) to improve selection and planning of patients with hepatocellular carcinoma (HCC) treated with holmium-166 (Ho)-microspheres radioembolization.
Results: Thirty-one patients with HCC were included and treated with Ho- radioembolization as part of a prospective phase 2 study. Twenty-seven patients were eligible for analysis, 67% had a cirrhotic liver morphology on imaging, 70% had multifocal disease and 51% had bilobar disease.
The Overuse of Hepatobiliary Scintigraphy (HIDA) Scans: Are We Unnecessarily Using Nuclear Medicine Resources Instead of Proven Clinical Guidelines for Diagnosing Acute Cholecystitis?

Background Gallstone disease significantly burdens the United States healthcare system. While ultrasonography (US), physical exam, and laboratory findings are the recommended primary workup and diagnostic modalities, hepatobiliary scintigraphy (HIDA) scans are occasionally used as an adjunct for diagnosis. This study evaluates HIDA scan utilization in comparison to clinical and US findings based on the Tokyo guidelines for diagnosing acute cholecystitis.

Aim: To investigate liver biochemistry in infants screened for biliary atresia (BA) at the time of hepatobiliary scintigraphy (HS) and to evaluate the effect of change in threshold for HS.
Methods: Infants born from 2010 to 2021, who underwent HS <6 months postpartum for BA, were included and data sourced from electronic medical records. The change in threshold in 2018 from ≥20 (and/or if conjugated bilirubin exceeds 20% of total bilirubin) to ≥17 μM (regardless of total bilirubin) was evaluated.

Article Synopsis
- This study explores the Double-vein Embolization technique used to enhance liver remnant size before major liver surgeries, with a focus on initial experiences at Semmelweis University, Hungary.
- Over a period of 16 procedures, results showed a 100% technical success rate with minimal complications, and significant increases in future liver remnant volume and function, indicating the technique's effectiveness.
- While outcomes align with existing literature, the authors emphasize the need for more research to determine how to best incorporate Double-vein Embolization into standard clinical practice.
