BACKGROUND. Literature on glenohumeral dislocations has focused on younger patient populations because of high recurrence rates. However, the spectrum of injuries sustained in younger versus older patient populations is reported to be quite different. OBJECTIVE. The purpose of this article is to describe MRI findings and management of anterior shoulder instability in the aging (≥ 60 years) population. METHODS. Shoulder MRI examinations of anterior glenohumeral dislocations in patients 40 years old and older were subdivided into groups younger than 60 years old or 60 years old and older and reviewed by two musculoskeletal radiologists for a Hill-Sachs lesion, other fracture, glenoid injury, capsulolabral injury, rotator cuff tear, muscle atrophy, and axillary nerve injury. Fischer exact test and logistic regression was evaluated for significant differences between cohorts, and interreader agreement was assessed. Surgical management was recorded, if available. RESULTS. A total of 104 shoulder MRI examinations (sts should have a high index of suspicion for acute rotator cuff tears in anterior shoulder instability, especially in aging populations. Greater tuberosity or coracoid fractures and axillary nerve injury occur across all ages, whereas Hill-Sachs injuries are more common in younger patients. CLINICAL IMPACT. Acute high-grade or full-thickness rotator cuff tears are seen with higher frequency in older populations after anterior glenohumeral dislocation. Osseous and nerve injuries are important causes of patient morbidity that if not carefully sought out may be overlooked by the interpreting radiologist on routine imaging. MRI utilization and need for monitored anesthesia care (MAC) in children have increased. However, MAC is associated with exam delays, increased cost, and safety concerns. To evaluate the success rate of non-sedated neuroradiological MRI studies in children 1-7 years old and to investigate factors associated with success. We retrospectively reviewed data from our institutional non-sedated MRI program. Criteria for inclusion were a) outpatient non-sedated MRI referral b) ages of 1-7 years and c) neuroradiology indication. Criteria for exclusion were a) ventricular check MRI exams and b) exams with contrast material. Success was determined by reviewing the clinical MRI report. We recorded the age, sex, type of exam (brain, spine, craniospinal, head and neck, and brain with MRA), protocol length, presence of child life specialist, use of video goggles, and time of the MRI appointment (routine daytime slot, evening slot). Descriptive statistics were used to summarize patient demographics and clinical data. Lto determine the need for MAC may lead to overutilization of these services. Dissemination of non-sedated MRI practice could reduce the rate of sedated MRI in young children. Using age as the primary criterion to determine the need for MAC may lead to overutilization of these services. Dissemination of non-sedated MRI practice could reduce the rate of sedated MRI in young children.BACKGROUND. The incidence of ductal carcinoma in situ (DCIS) has steadily increased, as have concerns regarding overtreatment. Active surveillance is a novel treatment strategy that avoids surgical excision, but identifying patients with occult invasive disease who should be excluded from active surveillance is challenging. Radiologists are not typically expected to predict the upstaging of DCIS to invasive disease, though they might be trained to perform this task. OBJECTIVE. The purpose of this study was to determine whether a mixed-methods two-stage observer study can improve radiologists' ability to predict upstaging of DCIS to invasive disease on mammography. METHODS. PD98059 mouse All cases of DCIS calcifications that underwent stereotactic biopsy between 2010 and 2015 were identified. Two cohorts were randomly generated, each containing 150 cases (120 pure DCIS cases and 30 DCIS cases u
