Hepatic MR imaging techniques, optimization, and artifacts.

Area of Science:

• Medical Imaging
• Radiology
• Magnetic Resonance Imaging

Background:

• Hepatic magnetic resonance (MR) imaging is crucial for diagnosing liver conditions.
• Standardized and optimized protocols are needed for consistent, high-quality liver imaging.
• Variations in scanner hardware and software can affect imaging performance.

Purpose of the Study:

• To describe a standardized 1.5-Tesla (T) hepatic MR imaging protocol.
• To provide strategies for optimizing pulse sequences and managing artifacts.
• To outline an effective sequence order for efficient and high-quality hepatic MR examinations.

Main Methods:

• Development of a basic 1.5-T hepatic MR imaging protocol.
• Strategies for pulse sequence optimization and artifact management.
• Emphasis on proper timing of postgadolinium 3-dimensional gradient echo sequences.
• Implementation across General Electric, Philips, and Siemens clinical scanners.

Main Results:

• A generalizable approach for efficient and high-quality hepatic MR imaging.
• Demonstrated applicability across multiple major clinical scanner platforms.
• Improved understanding of sequence optimization and artifact control in liver MR.

Conclusions:

• The described protocol provides a framework for consistent and high-quality hepatic MR imaging.
• Optimization strategies and sequence ordering enhance examination efficiency.
• The protocol's generalizability across different vendors facilitates widespread adoption.
