Oblique Axis Rib Stretch and Curved Planar Reformats in Patients for Rib Fracture Detection and Characterization: Feasibility and Clinical Application

Figure 1

Hand-drawn graphics indicate nondisplaced fractures ((a) blue arrow) and depict different types of displaced fractures ((b)–(e) red arrow). In Figures 1(f)–1(h), nondisplaced fractures are shown (blue arrow). Figures 1(b) and 1(i) exhibit displaced fractures with more than 1mm displacement of the bone cortex (red arrow). Figures 1(c) and 1(j) demonstrate a displaced fracture with more than 2mm displacement of the bone cortex (red arrow). Figures 1(d) and 1(k) show a clearly displaced fracture with complete displacement of margins of the cortex. Figures 1(e) and 1(l) demonstrate comminuted fracture, which is a special case of displaced fracture with three or more fragments (red arrow).
