There have been dramatic changes in diagnostic imaging over the last few years. Computed tomography (CT) has been challenged by magnetic resonance imaging (MRI) and ultrasound. Although MRI has established its place in neuroradiology, its role in the abdomen is less clearly defined. Ultrasound remains complementary to CT in its evaluation. In trauma, CT remains the modality of choice. Currently, CT scanners outnumber magnetic resonance installations, and CT examinations generally cost less than MRI. Computed tomography remains a viable imaging technique. Subsequently, a text dedicated to CT of the body will continue to have considerable value for diagnostic radiologists.
The second edition of this already well-received text has undergone several changes. Most noticeable are several new chapters in the first volume dealing with neurological CT. These include chapters on hydrocephalus and cerebral atrophy, intracranial calcifications, and demyelinating diseases. The chapter on CT of the spine has been rewritten, and that
