Breast MRI ordering practices in a large health care network

Area of Science:

• Radiology
• Medical Imaging
• Oncology

Background:

• Breast magnetic resonance imaging (MRI) is an advanced diagnostic tool.
• Understanding physician ordering patterns is crucial for optimizing imaging resource allocation.
• Limited awareness of breast MRI's clinical utility may affect its appropriate use.

Purpose of the Study:

• To assess breast MRI ordering practices among healthcare providers.
• To identify barriers and perceptions influencing breast MRI utilization.
• To inform educational strategies for improving breast MRI referrals.

Main Methods:

• An online survey was administered to primary care providers (PCPs) and specialists within an academic network.
• The survey collected data on provider demographics, ordering habits, challenges, and perceptions of breast MRI.
• Response rate was 26% (134 of 525 providers).

Main Results:

• Only 42% of surveyed providers order breast MRI, with 42% citing lack of familiarity as the primary reason.
• High-risk screening is the most common indication (84%) for breast MRI.
• Provider perceptions of clinical utility are mixed, but 30% order more breast MRI since density legislation, and 29% would order more for dense breasts if cost-effective options existed.

Conclusions:

• A significant knowledge gap exists regarding breast MRI indications and utility among referring providers.
• There is a growing interest in breast MRI for screening, particularly post-legislation.
• Targeted educational interventions by radiologists can enhance provider awareness and improve appropriate breast MRI utilization.
