Objective To evaluate the 3D respiratory-triggered T1 ρ sequences for clinical diagnosis of liver cirrhosis by visual quality and quantitative measurements. Methods 3D BLOCK T1 ρ was performed on 40 healthy volunteers and 17 liver cirrhosis patients on 3.0T magnetic resonance imaging (MRI). The 3D BLOCK T1 ρ method covered 26 slices. Visual scores of image quality, T1 ρ measurements of the sequence, and T1 ρ values of healthy volunteers and cirrhosis patients were compared using parametric tests. Results Average visual scores for volunteers and patients of the 3D BLOCK T1 ρ were 3.29 and 3.59..Differences of T1 ρ between healthy volunteers and patients wAs significant in 3D BLOCK T1 ρ sequences (P = 0.03). Conclusion 3D BLOCK T1 ρ with respiratory triggering should be considered as an alternative sequence for clinical diagnosis of liver cirrhosis due to its superior coverage.
