Purpose: To assess whether gadobenate dimeglumine (Gd-BOPTA)-enhanced MR imaging could predict hepatocellular carcinoma (HCC) diagnosis in small arterial enhancing-only nodules detected by contrast-enhanced computed tomography (CT) in patients with liver cirrhosis. Materials and Methods: We prospectively recruited 125 cirrhotic patients (67 males, and 58 females; age: 68 6 12.36 years) with 151 small (<2 cm in diameter) arterial enhancing-only nodules identified by contrast-enhanced CT. All patients were scanned by MR imaging before and after Gd-BOPTA injection during the hepatic arterial phase (HAP), portal venous phase (PVP), equilibrium phase (EP), and hepatobiliary phase (HP). Nodule characterization was based on reference imaging crite...
