Background: Given the limited capacity and suboptimal sensitivity of ultrasonography (US), gadoxetic acid disodium (Gd-EOB-DTPA)-enhanced magnetic resonance imaging (MRI) demonstrates good diagnostic performance for hepatocellular carcinoma (HCC). Some researchers have proposed that the abbreviated MRI (AMRI) protocols have potential as a surveillance tool. However, few studies have compared multiple AMRI protocols with complete Gd-EOB-DTPA contrast-enhanced MRI for HCC surveillance.

Background: The precise differentiation of intrahepatic cholangiocarcinoma (ICC) from atypical hepatocellular carcinoma (HCC) is vital for treatment strategy and prognostic prediction. In clinical practice, nearly 40% of HCCs demonstrate atypical manifestations, particularly HCCs with rim arterial phase hyperenhancement (APHE), which is challenging to differentiate from mass-forming ICC. Thus, we aimed to develop a diagnostic regimen of gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA) contrast-enhanced magnetic resonance imaging (MRI) combined with serum tumor markers in differentiating mass-forming ICC from atypical HCC in at-risk patients with the hepatitis B virus (HBV).

Article Synopsis
  • The study aims to improve brachial plexus imaging by introducing a contrast-enhanced 3D-STIR-VISTA sequence, enhancing image quality and contrast with surrounding tissues.
  • Thirty subjects participated, including patients with various injuries and conditions; comparisons were made between unenhanced and contrast-enhanced images using statistical tests.
  • Results show that while the signal-to-noise ratio for the brachial plexus remained unchanged, surrounding tissues had a reduced ratio with contrast, leading to significantly improved contrast and higher quality ratings for the contrast-enhanced images.
