With the introduction of MDCT technology, significant advances have been made in the ability to obtain high-resolution volumetric data during peak vascular contrast enhancement in patients who have chest injuries. This development has resulted in a marked increase in the number of hemodynamically stable sustaining chest traumas that are imaged with MDCT. The volumetric data that are acquired can be used to perform high-resolution axial, MPR, MIP, and three-dimensional color images. Improved image quality and manipulation of volumetric data allow a more accurate diagnosis of the extent and course of both blunt and penetrating injury, and often allow delineation of the precise injuries that have been sustained.The need for further diagnostic work-up or intervention frequently can be determined from the MDCT results.
