Initial experience with a next-generation low-field MRI scanner: Potential for breast imaging?

Area of Science:

• Radiology
• Medical Imaging
• Biomedical Engineering

Background:

• Clinical adoption of breast MRI is limited by availability and cost.
• Low-field MRI technology presents a potential solution to these challenges.
• Next-generation low-field scanners aim to enhance accessibility and reduce procedural expenses.

Purpose of the Study:

• To evaluate the initial clinical experience with a next-generation low-field 0.55T breast MRI scanner.
• To assess the feasibility and image quality of low-field breast MRI.
• To determine if diagnostic image quality can be achieved within acceptable scan times.

Main Methods:

• A prospective case series involving 12 participants.
• Utilized a 0.55T MAGNETOM Free.Max scanner with a seven-channel breast coil.
• Implemented a multiparametric MRI protocol including T1-weighted, T2-weighted, and diffusion-weighted sequences.

Main Results:

• Diagnostic image quality was achieved in all 12 participants without significant artifacts.
• Typical imaging phenotypes were visualized effectively.
• Complete non-abbreviated breast MRI scan times ranged from 10:30 to 18:40 minutes.

Conclusions:

• Low-field breast MRI at 0.55T is feasible and provides diagnostic image quality.
• The examination time is acceptable for clinical application.
• This technology holds promise for increasing breast MRI accessibility and affordability.
