Sectional anatomy is a subject of anatomy wherein the focus is on studying regions instead of systems. It helps to view a part of the body in different dimensions, which helps in creating three-dimensional (3D) images of the body parts. Sectional views of body are obtained using imaging techniques such as positron emission tomography (PET) and single-photon emission computed tomography (SPECT). PET is a functional imaging technique that utilizes safe injectable radioactive chemicals called radiotracers. It helps in visualizing and measuring alterations in metabolic processes and other physiological functions such as absorption, blood flow and regional chemical composition. On the other hand, SPECT is a tomographic imaging technique that uses gamma rays that can be detected by the CT scanner. The gamma ray emission is collected by the computer systems and the CT cross-sections are displayed. The computer then generates the three-dimensional image of the body part. This book explores all the important aspects of PET and SPECT imaging in the present day. Those in search of information to further their knowledge will be greatly assisted by it.

A positron emission tomography (PET) scan is a type of imaging test that can help reveal the metabolic or biochemical function of the tissues and organs inside the body. A radioactive drug called tracer is used to show both normal and abnormal metabolic activities within the body. There are various diseases including heart disease, brain disorders and cancer that can be diagnosed using a PET scan. A single-photon emission computerized tomography (SPECT) scan is a type of nuclear imaging test that shows the movement of blood towards the tissues and organs. In this medical imaging test, a radioactive substance is used to produce images of the internal structures and organs of the body. It is used to diagnose conditions such as stress fractures, strokes, seizures, infections, and tumors in the spine. This book provides new insights into the field of PET and SPECT imaging. It consists of contributions made by international experts. The book is appropriate for students as well as for experts seeking detailed information in the area of diagnostic imaging.

Medical imaging is the technique of producing images of the internal parts of the body. It facilitates medical intervention and clinical analysis, along with providing a visual representation of the functioning of tissues and organs. It reveals the internal structures that are covered by bones and skin, and helps in diagnosing and treating various diseases. Medical imaging makes use of various radiological and organic imaging techniques that utilize electromagnetic energies, sonography, isotope, magnetic, and thermal imaging. There are various types of medical imaging that are utilized currently for health care, including radiography, ultrasound, tomography, magnetic resonance imaging, photoacoustic imaging and echocardiography. Medical imaging is developing at a fast pace due to various developments in the techniques of image processing, including recognition, analysis and enhancement of images. Technological advancements that will contribute in presenting in depth visualization at the cell level are the future of medical imaging. This book contains some path-breaking studies on medical imaging. There has been rapid progress in this field and its applications are finding their way across multiple areas of medicine. This book will serve as a valuable source of reference for graduate and post graduate students.
