This manual is intended to fill a gap in the range of books on ultrasound diagnosis, concentrating exclusively on the diagnosis of infectious and tropical diseases. The book starts with a short introduction to ultrasound diagnosis. The main part describes and discusses the organ-related changes that can be detected with ultrasound in infectious and inflammatory diseases. The infectious and parasitic diseases that can successfully be diagnosed with ultrasound are presented in more detail. The important potential of interventional ultrasound diagnosis and therapy in infectious diseases is described. This richly illustrated volume has been written by leading experts from all over the world. It is primarily aimed at users of ultrasound diagnostic instruments in tropical and subtropical countries but will be valuable for physicians anywhere in the world confronted with these diseases.
