FIGURE 4.15. Radiographically occult femoral neck fracture detected by MR. (A) AP radiography of the right hip reveals generalized demineralization and old healed pubic rami fractures but no evidence for a femoral neck fracture. (B) Coronal T1-weighted image demonstrates a broad band of decreased signal traversing the femoral neck consistent with a subcapital femoral neck fracture. (C) Coronal proton density fat-suppressed image reveals a large zone of increased signal throughout the femoral neck consistent with marrow edema and an acute fracture.

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
