Magnetic resonance imaging of intraoral hard and soft tissues using an intraoral coil and FLASH sequences.

ABSTRACT:

Objectives

To ascertain the feasibility of MRI as a non-ionizing protocol for routine dentomaxillofacial diagnostic imaging. Wireless coils were used for MRI of intraoral hard and soft tissues.

Methods

FLASH MRI was applied in vivo with a mandible voxel size of 250 × 250 × 500 μm³, FOV of 64 × 64 × 28 mm³ and acquisition time of 3:57 min and with a maxilla voxel size of 350 μm³ and FOV of 34 cm³ in 6:40 min. Ex vivo imaging was performed in 4:38 min, with a resolution of 200 μm³ and FOV of 36.5 cm³. Cone beam (CB) CT of the mandible and subjects were acquired. MRI was compared to CBCT and histological sections. Deviations were calculated with intraclass correlation coefficient (ICC) and coefficient of variatio
