Imaging is used to view inside the body for medical analysis and clinical intervention. A variety of biomedical imaging techniques are utilized for managing all stages of cancer. Imaging plays an important role in cancer clinical protocols by providing metabolic, morphological, functional and structural information. In combination with other diagnostic tools, such as in vitro fluids and tissue analysis, it contributes in clinical decision‐making. Hybrid imaging techniques are capable of supplying complementary information for enhanced planning of therapy and staging. Targeted minimally invasive and image guided therapy can decrease collateral impacts and improve outcome. Cancer imaging has several benefits, such as minimal or no invasiveness, real time monitoring, and accessibility without tissue destruction and may help in functioning over a variety of size and time scales involved in pathological and biological processes. This book contains some path-breaking studies in clinical cancer imaging. It is a valuable compilation of topics, ranging from the basic to the most complex advancements. This book will prove to be immensely beneficial to students and researchers in this field.
