Malignancy
NO
To analyze the presence and extent of portosystemic shunting and its impact on survival outcomes using 4D Flow MRI to evaluate hemodynamic characteristics in the portal venous system.
To elucidate the distribution of intrahepatic portal blood flow using 4D Flow MRI and explore its relationship with the intraliver distribution of chemotherapeutic agents and their therapeutic effects.
Efficacy
1. Survival outcomes
2. Reduction in liver tumor size (according to RECIST criteria)
Observational
| 18 | years-old | <= |
| 100 | years-old | > |
Male and Female
1. Adult patients who are capable of understanding the contents of the research.
2. Patients with various degrees of portosystemic shunt and a control group of patients without portosystemic shunt. All are scheduled for abdominal contrast-enhanced MRI at our hospital for routine clinical purposes, such as the diagnosis and assessment of hepatocellular carcinoma, hepatic hemangiomas, metastatic liver tumors, shunts, and other tumors.
3. Patients scheduled for chemotherapy for primary liver tumors or metastatic liver tumors. All are regularly scheduled for abdominal contrast-enhanced MRI for routine clinical evaluation of primary or metastatic tumors.
4. Additionally, individuals who participated in the studies "Research on human vascular hemodynamics analysis using three-dimensional cine phase-contrast magnetic resonance imaging method (jRCTs041180157)" and "Hemodynamic study of the portal venous region using 3D cine phase contrast MRI(4D Flow MRI)(Approval number 2023-0140)" and have consented to the secondary use of their data for future research (must meet the criteria outlined in 2 or 3 above).
Individuals who have declined to participate in the study, those with contraindications for MRI such as metallic implants in the body or claustrophobia, and those who find it difficult to remain still for about an hour.
