(BQ) Part 2 book "Diagnostic imaging - Emergency" presents the following contents: Nontraumac (central nervous system, abdomen/pelvis, chest/cardiovascular, musculoskeletal). | Diagnostic Imaging Emergency fragment and the medial condyle of the humerus. This MR was obtained in a 13-year-old baseball pitcher with an acute injury. Right Anteroposterior radiograph shows reduction and screw fixation of the medial epicondyle avulsion fracture in the same patient. Left Anteroposterior radiograph shows avulsion of the tip of the medial epicondyle in a 12 year old who started pitching 3 weeks ago now with elbow pain and presenting for radiographs. Right Coronal T2WI MR in the same patient shows hyperintense signal throughout the medial epicondyle ossification center. The small osseous fragment could not be identified. This is an example of Little Leaguer s elbow.

Osborn MD FACR Overview Patients with a number of different nontraumatic disorders of the brain spine spinal cord and head and neck may present in the emergency department. While virtually any disease in any body part can be seen in the emergency department some of the most common urgent entities are discussed in this section. Nontraumatic Brain Emergencies Whom to Scan When to Scan Head CT scans in nontraumatized patients with CNS-related complaints are commonly obtained in emergency settings and account for 70-80 of all CT requests from emergency departments. Prospective studies have revealed that only 8 of such scans reveal clinically significant abnormalities. Of these cases over 95 have positive neurologic findings. Growing concerns about both the costs and the radiation exposure that occurs during CT acquisition have prompted attempts to identify clinical variables that are independent predictors of abnormal head CT findings in emergency department patients. Six such clinical variables have been identified 1 Age 70 years 2 Focal .
