“…Between these two hypotheses, the former mechanism was unlikely. In presence of intra-tendinous fibrosis, enhancement of the tendon should be visible; however, enhancement of the articular side of SST and IST was not observed in the previous articles related to contrast-enhanced MR findings in ACS (2930313233343536). Thus, the second hypotheses may provide more likely explanations for the development of stiffer SST and IST.…”

Objective To compare the elasticity of the supraspinatus tendon (SST) and infraspinatus tendon (IST) in patients with idiopathic adhesive capsulitis of the shoulder (ACS) with those in the control groups and to evaluate the relationship between age and tendon elasticity. Materials and Methods The Institutional Review Board approved this prospective, case-control study, which was conducted between November 2017 and March 2018, and informed consent was obtained from all participants. Control groups comprised healthy individuals or those with asymptomatic contralateral shoulders. Twenty-five shoulders in 20 participants in the ACS group (14 women; 53.5 ± 7.9 years) and 24 shoulders in 18 participants in the control group (6 women; 52.6 ± 10.5 years) were included. Elastography was performed in the oblique coronal plane at the neutral shoulder position. Mean/maximum/minimum velocity and stiffness from the shear-wave ultrasound elastography (SWE) and strain ratio (subcutaneous fat/target-tendon) from the strain ultrasound elastography (SE) of the SST and IST were evaluated. Statistical analyses were performed using the Mann-Whitney U test, receiver operating characteristic (ROC) curve, and Spearman correlation. Results Both velocity and stiffness in SWE were higher, and the strain ratio in SE was lower in participants with symptomatic shoulders than in those with normal shoulders ( p < 0.001). SST- and IST-mean velocity, mean stiffness, and strain ratios showed excellent area under the ROC curve (> 0.970). The elastic modulus was little correlated with age (ρ = −0.340–0.239). Conclusion SWE and SE indicated that SST and IST were stiffer in patients with ACS than in those with normal shoulders regardless of aging.

“…Sensitivity for detection of AC was low (56% with 95% CI: 23% – 85%). This compares unfavorably with the high reported sensitivity of MRI and MRA in this regard, which is reported in the range of 59–98%, depending on technique, imaging features and cutoffs [2, 13–16]. We suspect that this low sensitivity is at least partially explained by the lower spatial resolution of PET compared to that of MRI [17].…”

Focal uptake at the rotator interval or inferior capsule of shoulder on 18F-FDG PET/CT is associated with adhesive capsulitis

et al. 2017

Objective To determine if focal increased uptake at the rotator interval (RI) and/or inferior capsule (IC) on 18F-FDG PET/CT (“positive PET”) predicts the presence of adhesive capsulitis (AC). Materials and Methods Three populations were retrospectively examined. Group 1 included 1,137 consecutive 18F-FDG PET/CT studies and was used to determine the prevalence of focal uptake at the RI or IC. Group 2 included 361 cases from a 10-year period with 18F-FDG PET/CT and MRI of shoulder performed within 45 days of each other and was used to enrich the study group. Group 3 included 109 randomly selected patients from the same time frame as groups 1 and 2 and was used to generate the control group. The study group consisted of 15 cases from the 3 groups, which had positive PET findings. PET/CT images were assessed in consensus by two musculoskeletal radiologists. The reference standard for a diagnosis of AC was clinical and was made by review of the medical record by a pain medicine physician. Results The prevalence of focal activity at either the RI or IC (“positive PET”) was 0.53%. Nine patients had a clinical diagnosis of AC and 15 patients had a positive PET. The sensitivity and specificity of PET for detection of AC was 56% and 87%, respectively. PET/CT had a positive likelihood ratio for AC of 6.3 (95% CI: 2.8–14.6). Conclusion Increased uptake at the RI or IC on PET/CT confers a moderate increase in the likelihood of AC.

“…However, it was often observed in the subcoracoid fat triangle of these patients. Previous MRI studies also reported enhancement in the subcoracoid fat triangle due to abnormal inflammation . On angiography, abnormal angiogenesis was distributed at the medial side of the rotator interval near the subcoracoid fat triangle .…”

“…Previous studies suggested that SMI can be used to measure low‐velocity vascular flow with improved diagnostic accuracy in pediatric latent testis, liver tumors, and breast tumors compared with conventional Doppler imaging. Studies using contrast‐enhanced MRI, arthroscopic, and histologic observations revealed an abnormal increase in vascularity at the joint capsule in patients with adhesive capsulitis of the shoulder. An angiographic study investigating adhesive capsulitis also revealed abnormal vessels (most frequently at the rotator interval), indicating the key role of abnormal angiogenesis in the pathogenesis of adhesive capsulitis …”

Objectives-To assess the diagnostic accuracy of Superb Microvascular Imaging (SMI; Canon Medical Systems, Otawara, Japan) at the subcoracoid triangle for adhesive capsulitis of the shoulder, to compare the diagnostic value of SMI with that of conventional ultrasound (US) and power Doppler ultrasound (PDUS) findings, and to investigate the correlation between vascular flow on SMI with clinical features.Methods-Our study included 39 patients with a diagnosis of adhesive capsulitis and 35 healthy patients as a control group. The echogenicity in the rotator interval and coracohumeral ligament thickness were assessed with conventional US. Vascular flow in the subcoracoid fat triangle was evaluated with SMI and PDUS (SMI and PDUS areas). A receiver operating characteristic curve analysis was performed to evaluate diagnostic accuracy. The correlation between US findings and the range of motion, pain intensity, and duration of symptoms was also evaluated.Results-The SMI area was higher in the adhesive capsulitis group than in the control group (2.95 versus 0 mm 2 ; P < .01). The visualization of vascular flow at the subcoracoid fat triangle was superior with SMI compared with PDUS (P < .01). In the receiver operating characteristic analysis, the SMI area showed higher diagnostic performance, with an area under the curve of 0.90 compared with other US findings. The area of SMI vascular flow was also negatively correlated with external rotation and forward flexion (P < .05) in the adhesive capsulitis group.Conclusions-Measurement of vascular flow at the subcoracoid fat triangle using SMI facilitated the diagnosis of adhesive capsulitis. Superb Microvascular Imaging was superior to PDUS in diagnostic performance. Vascular flow was negatively correlated with the range of motion of external rotation and forward flexion.
