The most common types of cervical abnormalities and their radiographic findings are listed in Table 3 . Except for the clay shoveler's fracture, they should be assumed to be unstable and warrant continued immobilization until definitive therapy can be arranged. Any patient found to have one spinal fracture should have an entire spine series, including views of the cervical spine, the thoracic spine and the lumbosacral spine. The incidence of noncontiguous spine fractures ranges up to 17 percent. 27 , 28 Figures 7 through 9 demonstrate aspects of common cervical spine fractures.
Sinonasal polyposis is a typically extensive process with involvement of both the nasal cavity and the paranasal sinuses. By contrast, mucous retention cysts are typically limited to the sinus cavity in location. CT findings of sinonasal polyposis include polypoid masses in the nasal cavity, polypoid soft tissue masses in the sinuses, partial or complete pansinus opacification, and enlargement of the infundibula. Other findings include attenuation of the nasal septal and sinus trabeculae, and opacified ethmoid sinuses with bulging lateral walls. Chronic bony changes with thickening and sclerosis can be seen. 29,30 Truncation of the middle turbinate, with absence of the bulbous part of the bony middle turbinate, has been reported as a characteristic ancillary imaging finding in sinonasal polyposis, not seen in other patterns of sinusitis. 31 On CT, the polyps are usually hypodense or isodense in appearance; foci of increased attenuation may be seen with inspissation or superimposed fungal sinusitis (Figure 11).The initial treatment of sinonasal polyps is medical management, including intranasal or systemic steroids, and antibiotics. Surgery is reserved for those who do not respond to medical therapy. Medical treatment following surgery is essential in preventing recurrence. 32
Many radiologists were actually part of this trend as they wore their smartwatches at RSNA16. PC Magazine recently reviewed nine of the best smartwatches of 2017. Most of them place a variety of health and fitness apps on your wrist. Notable are the Apple watch and Pebble, and many are compatible with both the App store and Google Play. There’s also a team at Texas A&M working on a new smartwatch to help nurses manage their workloads. And there’s even a high-fashion connected watch by Breitling that will set you back $8,900.
