Fig. 3From: Understanding PI-QUAL for prostate MRI quality: a practical primer for radiologistsAxial (a), coronal (b) and sagittal (c) T2-weighted magnetic resonance imaging acquisitions of the same patient. Each acquisition was 4 min long, but the pixel size varied for each plane. The pixel size was 0.60 x 0.60 mm in (a), 0.67 x 0.67 mm in (b) and 0.80 x 0.80 mm in (c). This image shows that as the pixel size goes up, there is less noise but also that sharpness is reducedBack to article page
