Owing to the anatomic complexity of the neck and the diver sity of pathologic entities affecting it, the cervical region has long been of great semiological interest. Physical examination is an easy means of evaluating the size and origin of a solitary cervical mass, yet valid interpretation can prove difficult when the normal morphology of the neck has been altered; excellent examples are patients with extensive fibrosis or scarring secondary to previous irradiation or surgery. Like wise, physical examination cannot assess the relations of a pathologic process to adjacent structures - e. g.,...

This is the first book devoted solely to ultrasonography of the spleen. Its particular value to the reader can be explained by several factors: firstly, ultrasonography is the first examination to be performed after physical examination; secondly, splenic ultrasound can be performed rapidly in emergency settings and in an infectious context; thirdly, it is a necessary procedure for epidemiological work in regions such as Africa, where parasitoses are endemic; and, finally, it is useful for the work-up of neoplasms. The book is divided into chapters covering normal sonoanatomy of the spleen,...

Computerization of the radiological image (digitization, com puted tomography), the diagnostic contributions of ultra sonography, and the advent of magnetic resonance imaging all herald a new era in radiology. While this discipline retains its clinical nature, and continues to group together various specialities, the technical "common denominator" plays an increasingly important role, and requires a more global ap proach to the clinical problem. Centralization of state-of-the-art equipment in technical imaging centers - strategic points in future hospitals - will al low clinical radiologists...
