Comprehensive Textbook of Clinical Radiology is a fully integrated illustrated textbook of radiology to cater for residents and practising radiologists. It is a one-stop solution for all academic needs in radiology. It helps radiologists as a single reference book to gain complete knowledge instead of referring to multiple resources. More than 500 authors, recognized experts in their subspeciality, have contributed to this book. To meet the expectations of clinical radiologists, thorough clinical expertise and familiarity with all the imaging modalities appropriate to address their clinical questions are necessary, regardless of one’s favoured subspeciality. To keep the content relevant to them, we have tried to stay upgraded to their level. This book comprises six volumes, which gives information on Radiological Anatomy, Embryology, Nomogram, Normal Variants, Physics, Imaging Techniques, and all the aspects of Diagnostic Radiology including Neuroradiology, Head and Neck, Chest and CVS, Abdomen, Obstetrics and Gynaecology, Breast, Musculoskeletal and Multisystem Disorders & related Interventional techniques. It will serve as a primary reference for residents and subspeciality trainees and fellows to facilitate their learning in preparation for their examination, and also the consultant radiologists in their daily clinical practice. This volume is subdivided into three sections. Section 1 covers the principles of clinical radiology and deals with basic to advanced aspects of general radiology. The physics of each imaging modality is described in detail for radiology residents. Principles of pathology, genetics and statistics important for radiologists from research point of view are enumerated. Basic principles of medicine including management of contrast reactions, basic and advanced life support which are important for radiologists in day to day practice are dealt in dedicated chapter. Section 2 covers the multisystem disorders that affect multiple body systems either at the same time or over a period of time. Imaging plays a vital role in identifying the extent of systems involved and also in diagnosis by recognising the pattern of systems involved. The last part of the section deals with the general principles of oncoimaging dealing with multisystem involvement and facilitates easier understanding of this complex subject. The format is ideal for both in-depth knowledge and daily reference. Section 3 covers head and neck imaging, anatomy of neck, techniques of imaging and paediatric neck. In addition, all neck spaces and lymph nodes are discussed with anatomy and pathology with high-quality images and line diagrams. Orbits, temporal bone, sinuses and skull base are included with discussion on imaging anatomy, variants and pathologies. Cancer imaging, PETCT and post-operative imaging are fully discussed along with TNM imaging. Unique chapters on Sleep apnea, Emergency Radiology, Dental imaging, Superficial and trans-spatial lesions and Imaging of all cranial nerves are included.
