Study on sex differences and potential clinical value of three-dimensional computerized tomography pelvimetry in rectal cancer patients

Figure 4 Front and lateral view of the three-dimensional pelvic reconstruction between male and female patients in the forward tilt position and the mid-sagittal position respectively. A: Front view of the three-dimensional (3D) pelvic reconstruction in a male patient in the forward tilt position; B: Front view of the 3D pelvic reconstruction in a female patient in the forward tilt position; C: Lateral view of the 3D pelvic reconstruction in a male patient in the mid-sagittal position; D: Lateral view of the 3D pelvic reconstruction in a female patient in the mid-sagittal position. The male pelvis is deep and narrow, with a forward tilt, straighter sacrum, and a higher overall curvature. The female pelvis is wide and shallow, with a backward tilt and a smaller overall curvature.
