In the future the need for flush aortography prior to and after embolization may be obviated, when the use of multi-detector row CT becomes more and more common. There are indications that the use of thin-section CT scanning reduces procedural time, as well as the potential iatrogenic risks of a selective search for ectopic bronchial or abnormal non-bron-chial systemic arteries [19].

Trauma is one of the most common reasons for a child s attendance in the emergency department. Plain radiographs may remain the primary imaging modality following suspected skeletal injury, but with the advent of first single detector CT (SDCT) and now multi-detector row CT (MDCT) scanners, the role of CT in skeletal trauma has continued to develop.

When considering an abdominal multi-detector-row CT (MDCT) protocol to enable optimal diagnostic capability, there are several important factors that need to be considered. Most importantly, what is the clinical indication for the study This will enable the radiologist to tailor the CT protocol appropriately to obtain the diagnostic information requested. Appropriate tailoring of the protocol requires consideration of ...

Almost every year, new CT scanners are introduced, allowing investigation of any part of the body with the highest spatial and temporal resolution within the shortest scan time. CT angiography performed with multi-detector-row CT (MDCT) and dedicated contrast protocols visualize even the smallest of vessels in the periphery of any vascular tree. Coronary arteries are of particular challenge for imaging by CT because of their small size and their continuous rapid movement. With the newest MDCT scanners, however, any vascular territory, including the coronary arteries, is now assessable with detailed anatomic (Achenbach et al. 2006).
