Fracture detection with multi echo fast field echo (mFFE) MRI as a radiation-free alternative to CT

Area of Science:

• Orthopedic imaging
• Radiology
• Medical physics

Background:

• Magnetic resonance imaging (MRI) offers radiation-free bone imaging potential.
• Computed tomography (CT) is standard for bone fracture imaging but involves ionizing radiation.
• Complex knee fractures require accurate imaging for effective treatment.

Purpose of the Study:

• To develop and evaluate a novel MRI bone sequence as a CT alternative for complex knee fractures.
• To assess the efficacy of the new sequence in a clinical hospital setting.
• To provide radiation-free imaging for musculoskeletal trauma.

Main Methods:

• An optimized MRI sequence, Fracture Detection with multi-echo fast field echo (mFFE) MRI, was developed.
• The mFFE sequence was validated using a bone phantom and a clinical knee fracture case.
• The sequence aims to produce CT-like images for detecting cortical and trabecular bone fractures.

Main Results:

• The mFFE sequence demonstrated fracture visualization comparable to CT.
• Simultaneous soft tissue assessment was an additional benefit of the mFFE sequence.
• While MRI scan times are longer, AI acceleration may improve clinical applicability.

Conclusions:

• The developed MRI method is a promising radiation-free alternative for fracture imaging in musculoskeletal trauma.
• This technique has potential for clinical practice implementation.
• Findings contribute to standardizing MRI bone imaging protocols.
