Magnetic resonance fingerprinting: a technical review

Area of Science:

• Medical Imaging
• Biophysics

Background:

• Multiparametric quantitative imaging is increasingly vital in clinical settings.
• Magnetic resonance fingerprinting (MRF) is an emerging technique for rapid multiparametric quantitative imaging.

Purpose of the Study:

• To provide a comprehensive review of Magnetic Resonance Fingerprinting (MRF).
• To detail the key stages involved in MRF, including acquisition, dictionary generation, reconstruction, and validation.

Main Methods:

• Review of Magnetic Resonance Fingerprinting (MRF) acquisition protocols.
• Examination of dictionary generation strategies for MRF.
• Analysis of MRF reconstruction algorithms.
• Overview of MRF validation methodologies.

Main Results:

• MRF enables fast acquisition of multiple quantitative parameters simultaneously.
• The review synthesizes current approaches in MRF data processing and analysis.
• Validation studies confirm the accuracy and reliability of MRF.

Conclusions:

• Magnetic resonance fingerprinting is a promising technique for advanced quantitative MRI.
• Further research and standardization are expected to enhance MRF's clinical integration.
