What is the best imaging modality for the diagnosis of gallbladder carcinoma?
Metadata[+] Show full item record
Transabdominal ultrasound is the first-line imaging modality to detect clinically suspected gallbladder carcinoma, although estimates of sensitivity vary widely (25%-85%). (SOR: B, based on retrospective cohort studies.) Endoscopic ultrasonography, thin-slice computed tomography (CT), magnetic resonance imaging (MRI), and magnetic resonance cholangiopancreatography (MRCP) can further detail the extent of primary gallbladder carcinoma. (SOR: C, based on expert opinion.)
