Quantitative ultrasound assessment of fatty infiltration of the rotator cuff muscles using backscatter coefficient

Background To prospectively evaluate ultrasound backscatter coefficients (BSCs) of the supraspinatus and infraspinatus muscles and compare with Goutallier classification on magnetic resonance imaging (MRI). Methods Fifty-six participants had shoulder MRI exams and ultrasound exams of the supraspinat...

Description
Summary:Background To prospectively evaluate ultrasound backscatter coefficients (BSCs) of the supraspinatus and infraspinatus muscles and compare with Goutallier classification on magnetic resonance imaging (MRI). Methods Fifty-six participants had shoulder MRI exams and ultrasound exams of the supraspinatus and infraspinatus muscles. Goutallier MRI grades were determined and BSCs were measured. Group means were compared and the strength of relationships between the measures were determined. Using binarized Goutallier groups (0–2 versus 3–4), areas under the receiver operating characteristic curves (AUROCs) were calculated. The nearest integer cutoff value was determined using Youden’s index. Results BSC values were significantly different among most Goutallier grades for the supraspinatus and infraspinatus muscles (both p
