MSCT AN INTRODUCTION TO A NOVEL TECHNIQUE Dr Hazem Abu Zeid Yousef Lecturer of Radiodiagnosis Faculty of Medicine Assiut University INTRODUCTION The introduction of spiral CT in the early 1990s resulted in fundamental and far-reaching improvement of CT imaging For the first time volume data could be acquired without mis-registration of anatomical details, which initiated the development of 3D image processing techniques such as multi-planar reformations (MPRs), maximum intensity projections (MIPs), surface-shaded displays (SSDs) or volume renderings As an important application CT angiography (CTA) has been established in clinical practice As a consequence of increasing clinical demands, single-slice spiral CT with 1-s gantry rotation time soon encountered its limitations Larger volume coverage and improved transverse resolution can be achieved by simultaneous acquisition of more than one slice and by a shorter gantry rotation time The first step towards multi-slice acquisition was a two-slice CT scanner introduced in 1993 (Elscint Twin) In 1998 all major CT manufacturers introduced multi-slice CT systems which brought about considerable improvements of scan speed, transverse resolution and utilization of the tube output SOME CLINICAL APPLICATIONS OF MDCT MDCT ANGIOGRAPHY CEREBRAL ANGIOGRAPHY CONTRAST ENEMA MDCT FISTULOGRAPHY ASSESSMENT OF POLYTRAUMA FRACTURE MANDIBLE FRACTURE CX SPINE FRACTURE L.S.S FRACTURE PELVIS THANK YOU
