Children differ physiologically from adults and are susceptible to abnormalities in development and maturation not seen in adults. They differ in anatomy (e.g., the thymus) and are more susceptible to the harmful effects of ionizing radiation. This chapter will highlight some…
Advances in neuroimaging have had a remarkable impact on the diagnosis and treatment of neurologic diseases ranging from earlier detection and treatment of stroke to a more timely diagnosis of dementia, from the rapid detection and treatment of cerebral aneurysms…
Abdominal Trauma The role of advanced imaging techniques deserves special mention in abdominal trauma. Radiology has made a significant impact on the lives of traumatized patients by distinguishing those patients who can be managed conservatively from those who need surgical…
Trauma is the leading cause of death, hospitalization, and disability in Americans from the age of 1 year through age 45. The major imaging findings of chest trauma will be discussed in this chapter. Table 24.1 summarizes some of the traumatic…
Recognizing an Acute Fracture Recognizing a fracture seems to hold a certain attraction for many. They are a favorite among those learning radiology, perhaps because of how common and seemingly straightforward they are. In this chapter we tell you how…
Back pain, particularly low back pain, is the leading cause of years lived with a disability worldwide, a measure reflecting the impact an illness has on quality of life. In 2017, studies estimated that at any given moment 577 million…
Conventional Radiography, CT, and MRI in Bone Imaging Most examinations of bone start with conventional radiographs obtained with at least two views exposed at a 90-degree angle to each other (called orthogonal views ) so as to localize abnormalities better…
Magnetic resonance imaging (MRI) is a diagnostic modality capable of producing both anatomic and physiologic data that utilizes the molecular composition of tissues, especially water, to generate images with extraordinary contrast between soft tissues, surpassing the sensitivity of other imaging…
In this chapter, we will discuss some additional applications of ultrasound (US), including vascular ultrasound, pediatric applications of ultrasound, and point-of-care ultrasound. Case Quiz 19 Question This is a sagittal US image of the chest/right upper quadrant in a 75-year-old…
Ultrasound is a diagnostic imaging tool that makes use of probes (transducers) that can produce an acoustical frequency that is hundreds of times greater than humans can hear and that utilizes acoustical energy to localize and characterize human tissues. Case…
