Improving MR Image Quality in Patients with Metallic Implants.

Area of Science:

• Radiology
• Medical Imaging
• Biomedical Engineering

Background:

• Increasing prevalence of implanted devices (orthopedic, cardiac) in aging populations.
• Patients with implants often require Magnetic Resonance Imaging (MRI) for diagnosis.
• Implanted ferromagnetic or paramagnetic materials cause significant MRI artifacts, hindering diagnostic capabilities.

Purpose of the Study:

• To outline strategies for minimizing MRI artifacts caused by implanted devices.
• To enhance diagnostic image quality and radiologist confidence in patients with implants.

Main Methods:

• Prioritizing patient safety by confirming implant presence before MRI.
• Selecting appropriate MRI systems considering field strength and sequence availability.
• Optimizing MRI parameters (bandwidth, voxel size, echo) and employing advanced metal artifact reduction sequences.

Main Results:

• Knowledge of implant presence is critical for safe MRI examination.
• Careful selection of MRI systems and sequences can significantly reduce metal artifacts.
• Appropriate patient positioning and parameter adjustments improve image quality.

Conclusions:

• Successful MRI of patients with implants is achievable through meticulous planning and artifact reduction techniques.
• Optimized MRI protocols enhance diagnostic confidence and image quality.
