1. Recognize MDCT signs of hypovolemic shock complex in the setting of blunt trauma. 2. Highlight the importance of early detection and significance of the findings in the management of patients that present to the emergency department. 3. Review of the literature of prevalence of radiological findings in shock.

1. Review the pathophysiology of hypovolemic shock and its main etiology in trauma 2. Discuss the findings on MDCT imaging: • Bowel wall thickening and enhancement (i.e. shock bowel) • Presence of intraperitoneal or retroperitoneal free fluid • Abnormal enhancement of solid organs including pancreas, spleen, liver, kidneys, and adrenal glands • Edema surrounding the peri-hepatic IVC (i.e. halo sign) • Flattening of IVC and aorta • Acute contrast extravasation 3. Highlight the management of patient who present to the emergency department with positive findings to suggest hypovolemic shock
