CT Anatomy

Part of the Medical Radiology book series (MEDRAD)


Usually, in normal subjects the peritoneum is not detectable on CT, because it is extremely thin. Only occasionally, and in particular regions, do both parietal and visceral peritonea appear as a dense thin linear image with uniform thickness, when it is limited on both sides by adipose tissue and is vertically oriented. This condition occurs in the case of the parietal peritoneum at the abdominal level, when it is compressed between preperitoneal space fat and omental fat (Fig. 4.1), and at the pelvic level, where it is limited on both sides by intra- and extraperitoneal adipose tissue (Figs 4.5, 4.6,4.8– 4.9, 4.10 4.11). Furthermore, it can be detected as a linear image produced by the reciprocity between peritoneum and fasciae, as in the case of the anterior renal fascia or for the umbilical fasciae, which are closely adherent to the peritoneum (Fig. 4.11).
