Practical Differential Diagnosis for CT and MRI

A concise reference for everyday practice Practical Differential Diagnosis in CT and MRI is a one-stop resource for the differential diagnosis of common and rare radiologic findings and conditions in all regions of the body. For each finding and diagnosis, the book provides a complete list of differential diagnoses as well as the features that will help the clinician differentiate diseases with similar findings. Highlights: Concise descriptions aid the identification of key radiologic signs Easy-to-use tables and bullet-point lists facilitate rapid review of important information about findings, differentiating features, and disease entities This pocket-sized book is ideal for residents preparing for board examinations as well as for radiologists in practice.
