Post-treatment malignant liver lesions. MR imaging

Area of Science:

• Medical Imaging
• Oncology
• Hepatology

Background:

• Magnetic resonance (MR) imaging is a highly accurate tool for diagnosing and staging liver tumors, aiding surgical planning.
• It plays a vital role in evaluating the liver post-treatment, including surgical resection, systemic or local therapies, and transplantation.
• Early detection of complications and tumor recurrence with MR imaging allows for timely treatment adjustments.

Purpose of the Study:

• To highlight the utility of MR imaging in liver tumor management.
• To discuss its role in assessing response to various treatment modalities.
• To explore its application in liver transplantation and future potential in guiding real-time therapies.

Main Methods:

• Review of MR imaging applications in liver tumor diagnosis, staging, and treatment monitoring.
• Analysis of MR imaging findings in response to surgical resection, systemic therapies, local therapies, and chemotherapy.
• Discussion of MR imaging's role in pre- and postoperative assessment for liver transplantation.

Main Results:

• MR imaging demonstrates high accuracy in tumor diagnosis, staging, and surgical planning.
• It effectively evaluates treatment response and detects recurrence, enabling treatment modification.
• The interpretation of treatment response, especially with chemotherapy, requires careful consideration of timing and therapy-specific changes.

Conclusions:

• MR imaging is indispensable for comprehensive liver tumor management, from diagnosis to post-treatment surveillance.
• Its ability to visualize treatment effects and recurrence is critical for patient care.
• Future directions include real-time MR imaging guidance for local therapies and enhanced monitoring during chemotherapy.
