In addition, radiation patient dose must justified in context adding diagnostic value. Techniques quantitative utility specific applications are important, protocols tailored answer need. Finally, newer post-processing techniques, including surface rendering, maximum intensity projections (MIP), 3-D displays multimodality image integration can certainly helpful diagnosis usually they improve referring clinicians' comprehension, however these methods may not necessarily provide additional information.
