Radiology is a medical discipline that uses imaging technology for diagnosing and treating diseases. It can be broadly divided into two categories, namely, diagnostic radiology and interventional radiology. Diagnostic radiology is used to view the structures or parts within the body. There are several types of imaging techniques including computed tomography (CT), fluoroscopy, magnetic resonance imaging (MRI), mammography, ultrasound, etc. Interventional radiology is a type of radiology that utilizes imaging techniques to help guide medical procedures. It uses minimally invasive procedures for treating different medical conditions. Angiography or angioplasty and stent placement, embolization to control bleeding, cancer treatments including tumor embolization using chemoembolization or Y-90 radioembolization, vertebroplasty, and kyphoplasty are a few important interventional radiology procedures. This book provides comprehensive insights into the field of radiology. A number of latest researches have been included to keep the readers up-to-date with the global concepts in this area of diagnostic imaging. This book will serve as an invaluable source for students and radiologists.
