Radiology is a medical specialty, which uses imaging techniques for the treatment and diagnosis of diseases occurring in the human body. Ultrasound, X-ray radiography, computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET) are some of the techniques used. Some of the subspecialties in radiology are musculoskeletal imaging, neuroradiology, pediatric radiology, nuclear medicine, emergency radiology, etc. Various forms of arthritis, congenital skeletal anomalies, bone tumors and fractures can be diagnosed by projectional radiography. Similarly using low energy projectional radiography, such as in dual-energy X-ray absorptiometry (DXA) and mammography, osteoporosis and breast cancer may be evaluated. CT scanning is the preferred diagnostic technique for detecting cerebral hemorrhage, aortic dissection, pulmonary embolism, appendicitis, etc. The various studies that are constantly contributing towards advancing technologies and evolution of diagnostic radiology are examined in detail in this book. It attempts to understand the diagnostic techniques used in this field and how such concepts have practical applications. It is a vital tool for all researching or studying diagnostic radiology as it gives incredible insights into emerging trends and concepts.
