We have reviewed the normal imaging anatomy of the heart and lungs in the previous two chapters. Make sure to come back to them for a brush-up whenever needed. Recognizing the difference between normal anatomy and what is abnormal is…
Emphasizing conventional radiography first, we will begin with an assessment of heart size, then describe the normal and abnormal contours of the heart on the frontal radiograph and, finally, discuss the normal anatomy of the heart as seen on computed…
In this chapter, you will learn the normal anatomy of the lungs as depicted by conventional radiographs and chest CT. To become more comfortable interpreting images of the chest, you should first be able to recognize fundamental, normal anatomy to…
This chapter will enable you to evaluate the technical adequacy of a chest x-ray by helping you become more familiar with the diagnostic pitfalls certain technical artifacts can introduce. This is important so that you don't mistake technical deficiencies for…
This chapter provides a brief introduction to the major imaging modalities. Accompanying most of the modalities is a Case Quiz that uses that modality. A number 2 pencil is not necessary for the quiz. The answers to the quizzes are…
Abdominal wall disorders are frequently encountered in clinical practice, and may be associated with significant morbidity. Most abdominal wall or groin hernias can be easily diagnosed by inspection and palpation. In these cases, radiologic examinations are useful for preoperative demonstration…
Primary Neoplasms Primary tumors arising from the peritoneum are rare and are usually of mesenchymal origin. DESMOID TUMORS These tumors are related to benign but locally aggressive fibroblast proliferation or fibromatosis. The morbidity associated with these tumors is related to…
