<b>Four-Channel Multidetector CT in Facial Fractures:</b> Do We Need 2 × 0.5 mm Collimation?

Abstract

Although thin multiplanar reformations obtained from thin collimation (2 x 0.5 mm) are statistically superior for the detection of subtle fractures, 4 x 1 mm collimation is sufficient for routine diagnostic evaluation. Ultra-high-resolution mode with 120 mAs is mandatory for detection of clinically relevant fractures.
