“…A similar method using MR arthrography was reported in another study using an oblique sagittal T1-weighted image selected at the level of the coracoid base [27]. More recently, Schiefer et al [29] reported high intraobserver and interobserver agreement when investigators had full access to the examinations without specifying a definitive plane or image. Fuchs et al [7] reported interobserver agreement between two raters, a musculoskeletal radiologist and a radiology fellow.…”

“…Another group [29] reported good interobserver and interobserver agreement among six raters using the MRI adaptation of the Goutallier et al scale, including three shoulder surgeons and three musculoskeletal radiologists. The surgeons showed higher intraobserver agreement and interobserver agreement compared with radiologists.…”

“…However, Slabaugh et al 35 reported kappa values of 0.43 and 0.56 for inter-and intra-observer agreement, respectively, in a group of 30 experienced shoulder surgeons. Schiefer et al 36 demonstrated that inter-observer agreement was higher among three orthopaedic surgeons (kappa scores 0.72 to 0.82) than among three radiologists (kappa scores 0.61 to 0.66). Our inclusion of the attending orthopaedic surgeon as the primary observer for statistical calculations on Goutallier grades was based on maximizing clinical relevance and also represents the most reproducible observations based on the previous literature.…”

Background: The modified Goutallier classification system describes the fatty infiltration of rotator cuff musculature (RCM) seen on magnetic resonance imaging (MRI) to assist with surgical decision-making for patients with rotator cuff tears (RCT). We describe the relationship between body mass index (BMI) and fatty infiltration in patients without RCT. Methods: Twenty-five patients from each of four different BMI ranges (< 25 kg/m 2 ; 25 kg/m 2 to 30 kg/m 2 ; 30 kg/m 2 to 35 kg/m 2 ; > 35 kg/m 2) were randomly selected from 1088 consecutive shoulder MRI scans (T1 parasagittal series). Four physician-readers evaluated MRI scans and assigned modified Goutallier grades (0 to 4) in each of the four rotator cuff muscles, as well as two adjacent muscles. Results: Grade distributions varied significantly based on BMI category for infraspinatus (p ¼ 0.001), teres minor (p < 0.001), subscapularis (p ¼ 0.025), teres major (p < 0.001) and deltoid (p < 0.001). Higher grades were evident with a diagnosis of diabetes mellitus in three of six muscles (p < 0.05), hyperlipidaemia in one muscle (p ¼ 0.021) and greater patient age in three muscles (p < 0.05). Conclusions: Obese and severely obese patients without RCT have more fatty infiltration seen on MRI. Patient factors (older age and diagnosis of diabetes mellitus) can be predictive of fatty infiltration in RCM. Fatty infiltration of RCM is not solely attributable to the presence of a RCT.

“…4). Diese Einteilung wurde ursprünglich für die CT-Diagnostik beschrieben, erlaubt jedoch auch im MRT eine valide Beurteilung [6,7]. Hierzu müssen bei der Fragestellung nach der Muskelqualität die parasagittalen T1-Sequenzen weit genug nach medial "gefahren" werden, um die Muskelbäuche abzubilden (▶ Abb.…”
