Advances in sonography present a challenge to clinicians in selecting the most appropriate imaging tool for evaluating patients' vascular problems. Based on a 1996 Radiological Society meeting at which two of the editors conducted a course on ultrasound, these seven chapters cover sonographic techniques and anatomy, clinical summary information, differential diagnostic considerations, and technical and interpretative errors. Includes color Doppler images. Dr. Bluth is in the department of radiology at Ochsner Clinic in New Orleans. Other contributors hail from US medical schools coast-to- coast. Annotation c.
