A typical patient’s diagnostic work-up is often incomplete without a medi‐ cal imaging technique. The various techniques for achieving this have continued to evolve, from the basics through the sophisticated and now to the abstract. The concept of Medical imaging has therefore continued to widen, from the conventional like X-rays, ultrasound, CT, PET CT, MRI and nuclear Scintigraphy, to include various other recording and meas‐ urement techniques which may be documented by mapping or graphs. This new book on ‘Medical Imaging in Clinical practice’ is another bold attempt to highlight the various research efforts and adaptations of newer and emerging techniques in the ever increasing world of medical Imaging. It seeks to explore the clinical applications of these newer techniques, while drawing parallels with the more conventional methods. It is by no means exhaustive, but achieves the overall purpose of widening the scope of knowledge and the readers’ perception of the amazing world of medical Imaging. I am sure, that most readers will not only be impressed, but encouraged to explore this ever evolving specialty of Medical Imaging and the bright hopes it offers in the future of clini‐ cal practice.
