First immunohistochemical evidence of human tendon repair following stem cell injection: A case report and review of literature

Figure 1 Proton density weighted, fat saturated, Turbo Spin Echo, 1. 5 T magnetic resonance imaging scans of the right shoulder of the investigated patient (matrix 320 × 320; slice thickness 3 mm; inter-slice gap 0.3 mm; echo time 37 ms; repetition time 2450 ms at baseline and 3480 ms at 10 wk post injection). A and B: Coronal scans at baseline (BL) (white arrows, trauma-related bruising; orange arrows, position of the supraspinatus tendon at which a hyperintense structure was found at 10 wk post injection (W10) but not at BL; blue arrows, clavicle; yellow arrows, coracoid process of the scapula); C: Sagittal scan at BL (white arrow, trauma-related bruising; orange arrow, position of the supraspinatus tendon at which a hyperintense structure was found at W10 but not at BL; blue arrow, acromion; dotted lines, long axis of the humeral shaft and delineation of the humeral head, with same angle between the lines as in Panel G); D: Axial scan at BL (white arrow, trauma-related bruising; orange arrow, position of the supraspinatus tendon at which a hyperintense structure was found at W10 but not at BL); E and F: Coronal scans at W10 (green arrows, hyperintense structure at the position of the supraspinatus tendon that was found at W10 but not at BL; blue arrows, clavicle; yellow arrows, coracoid process of the scapula); G: Sagittal scan at W10 (white arrow, trauma-related bruising; green arrow, hyperintense structure at the position of the supraspinatus tendon that was found at W10 but not at BL; blue arrow, acromion; dotted lines, long axis of the humerus and delineation of the humeral head, with same angle between the lines as in Panel C); H: Axial scan at W10 (white arrow, trauma-related bruising; green arrow, hyperintense structure at the position of the supraspinatus tendon that was found at W10 but not at BL). BL: Baseline; PD TSE: Proton density weighted turbo spin echo; W10: 10 wk post injection.
