Hepatocellular carcinoma (HCC) and biliary tract cancers (BTC) pose significant diagnostic and therapeutic challenges. Magnetic resonance imaging (MRI) and multiphase computed tomography (CT) have been the preferred imaging modalities for diagnosis, staging, and surveillance of patients with these malignancies. The best clinical outcomes depend on the appropriate selection of treatment options from the tools available in neo-adjuvant therapy, surgical resection, locoregional therapy, liver transplantation, and adjuvant therapy.

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.

Positron-emission tomography magnetic resonance imaging (PET/MRI) has emerged as a powerful hybrid molecular imaging technique in clinical practice, overcoming initial technical challenges to provide comprehensive anatomic and metabolic information. This advanced modality combines the superior soft tissue contrast of MRI with the metabolic insights of PET, offering advantages in hepatobiliary imaging, including improved detection of small liver metastases and reduced radiation exposure. The evolution of PET/MRI technology has been marked by significant advancements, such as the development of MRI-compatible PET detectors and sophisticated motion compensation techniques.
