Supine breast MRI with a wearable coil (BraCoil) improves lesion localization and clinical workflow for US-guided biopsy

Motivation: Supine breast MRI might enable higher image correlation to supine ultrasound (US) and therefore facilitate the clinical workflow. Goal(s): The aim was to quantify lesion displacement between supine US, prone MRI, and supine MRI in Cartesian and panoramic views, and derive the impact on the clinical workflow. Approach: Using MRI and US patient data, the spatial lesion displacement was measured. For supine MRI a wearable breast coil (BraCoil) was used. Results: Supine MRI shows comparable lesion position compared to US, in contrast to prone MRI. 18% of the lesions could only be localized in 2nd look US or biopsy after supine BraCoil MRI. Impact: Supine breast MRI with a wearable coil could improve the clinical workflow by facilitating lesion localization for 2nd look US, biopsy, or surgery.
