The validity of ultrasound and shear wave elastography to assess the quality of the rotator cuff

ConclusionSWE is not a valid method to measure the amount of FI or muscle atrophy in the SSP muscle. Therefore, SWE is not a suitable alternative for MRI in standard preoperative diagnostics in rotator cuff pathologies.Clinical relevance statementShear wave elastography should not be used in the diagnostics of rotator cuff pathologies.Key Points• There is a fair correlation between the Goutallier stage of the supraspinatus and infraspinatus muscle assessed on MRI and CT and visual assessment of fatty infiltration achieved on US.• Shear wave elastography is not a valid tool for the determination of the amount of fatty infiltration or muscle atrophy.• Shear wave elastography should not be used as a cheaper and less burdensome alternative for diagnostics in rotator cuff pathologies.
