The Second Edition Computed Body Tomography with MRI Correlation in 1989, significant technical advances have been made in both computed tomography (CT) and magnetic resonance imaging (MRI). The introduction of the helical (spiral) technique provides the unique opportunity to perform volumetric imaging and allows for further expansion of clinical applications of CT. Procedures such as CT angiography, virtual colonoscopy, and bronchoscopy have been developed because of helical scanning. The development of ultrafast CT scanning with electron beams has made imaging of the heart and pulmonary vasculature possible.

These new advances have enabled CT to remain as the tomographic procedure of choice in evaluating most, if not all, thoracic and abdominal diseases.
During this same period of time, innovations and refinement in MR hardware and software technology have continued. The superiority of MRI over CT for evaluating many diseases of the central nervous system and the musculoskeletal and cardiovascular systems has been well established. The use of fast imaging sequences, fat saturation techniques, and intravenous contrast agents (e.g., gadolinium compounds) has made it possible to produce exquisite images of the abdomen and pelvis in a matter of seconds. Although MRI is not a screening procedure used for evaluating the abdomen and pelvis, it, nevertheless, has been used with increasing frequency as a problem-solving method in these areas. The role of MRI in thoracic imaging is still limited.
This edition has been prepared to present a comprehensive text on the application of CT and MRI to the extracranial organs of the body. Because of the large amount of information available for inclusion, we have elected to publish the Third Edition in two volumes. The book is intended primarily for the radiologist to use in either clinical practice or training. However, the internist, pediatrician, and surgeon can derive helpful information about the relative value and indications for CT and MRI of the body as well. As in the first two editions, anatomy in each area is emphasized initially, since such knowledge is basic to proper interpretation. The CT and MRI findings in a variety of pathologic conditions are described and illustrated. Instruction is provided to optimize the conduct, analysis, and interpretation of CT and MR images. Both technical and interpretative errors can occur in CT and MRI examinations and we hope the readers will benefit from our collective past experience.
Logical and cogent discussion of how CT and MRI are properly integrated with other clinical and radiological procedures, as well as with each other, for a variety of problems are included. Both radiologists and referring clinicians often face
the dilemma of determining the best imaging approach for establishing a specific diagnosis given a set of clinical findings. With the increasing availability of a wide variety of imaging techniques, there is often a tendency to perform a large number of examinations before drawing a conclusion. This “shot-gun” or nondiscriminatory approach not only subjects the individual patient to unnecessary discomfort and risk, but also will be cost-prohibitive as managed care and capitation become more common methods of reimbursement in health care.
The task of deciding which diagnostic text is most appropriate for a given clinical problem has become an important part of our practice. An adequate understanding of clinical issues, as well as the advantages and limitations of each imaging technique, is essential for the radiologist to best help the referring clinician. Our recommended uses of CT and MRI have been developed through the cooperative efforts of the diagnostic radiology staffs at our three medical centers. Each staff member has established an interest and expertise in a specific anatomic area. The proper sequencing of imaging tests for a variety of clinical entities has been discussed in numerous joint consultations and conferences during the past two decades, and from them, our current ideas have evolved. We are well aware that equally valid alternative imaging approaches to certain clinical problems are possible. Differences in available equipment and personal experience also could influence the selection of a particular imaging method. It is safe to predict that our recommendations on the optimal use of CT and MRI will have to be modified with further technologic improvements and increasing knowledge in both CT and MRI in the future.
