Figure 4

Longitudinal and transverse scanning of the superior and lateral face of the left knee. Images of the DFE were obtained with the infant lying supine and the left knee at 90° flexion. The superior and lateral face of the knee were ultrasonographically evaluated."

Figure 5

Sonographic findings of hand and wrist in patients of various ages (girls in this figure). (A) Sketch maps of the distal radius and ulna, metacarpal and phalanx. The epiphysis is delineated by a dotted line. The hyper-echoic surface of ossification center and the cortex of the diaphysis are delineated by solid lines; (B) Sonographic findings for radius, ulna, metacarpals and phalanx; the dotted lines represent measurements of the diameters of the epiphysis and ossification center. d/ D = ratio of the diameter of the ossification center to that of the epiphysis. The value of d/D was 0% when no ossification center emerged and 100% when the ossification center fused with the diaphysis and no hypo-echoic epiphyseal plate between them could be identified. DDia, diaphysis; Epi, epiphysis; MC, metacarpal; Med, medial; MP, middle phalanx; Ossi, ossification center; PP, primary phalanx."
