To investigate whether quantitative liver-portal vein contrast ratio (Q-LPC) can be used as a substitute for quantitative liver-spleen contrast ratio (Q-LSC) in the hepatobiliary phase (HBP) contrasting degree. Q-LSC and Q-LPC were calculated in HBP images that were obtained approximately 20 min after gadolinium-ethoxybenzyl-diethylenetriamine penta-acetic acid injection, and relationship between them was evaluated. A very strong correlation was observed between Q-LSC and Q-LPC with respect to Child-Pugh class. Furthermore, Q-LPC values were not significantly different between patients with splenectomy or Gamna-Gandy bodies and those without. Therefore, Q-LPC can be useful instead of Q-LSC in patients with splenectomy or Gamna-Gandy bodies.

Background: Macrotrabecular-massive hepatocellular carcinoma (MTM-HCC) is a novel subtype of HCC, one of eight distinct subtypes, that accounts for 5% of all cases of HCC and is associated with a worse prognosis. Preoperative diagnosis of MTM-HCCs using imaging findings can facilitate patient treatment decision-making. The purpose of this study was to describe computed tomography (CT) and magnetic resonance imaging (MRI) findings of MTM-HCCs and compare these findings with histopathological features.

Objectives: To evaluate the performance of a radiomics nomogram developed based on gadolinium-ethoxybenzyl-diethylenetriamine penta-acetic acid (Gd-EOB-DTPA) MRI for preoperative prediction of microvascular invasion (MVI) of hepatocellular carcinoma (HCC), and to identify patients who may benefit from the postoperative adjuvant transarterial chemoembolization (PA-TACE).
Methods: A total of 260 eligible patients were retrospectively enrolled from three hospitals (140, 65, and 55 in training, standardized external, and non-standardized external validation cohort). Radiomics features and image characteristics were extracted from Gd-EOB-DTPA MRI image before hepatectomy for each lesion.

Background: Liver-spleen contrast in the hepatobiliary phase highly depends on the devices used for liver function tests. This study aimed to develop and validate a method to convert liver-spleen contrast data acquired with another device to reference liver-spleen contrast data, using the regression line of phantom contrasts (i.e.
