BACKGROUND AND PURPOSE Functional MR imaging has been used to study patterns of hippocampal activation that distinguish pathologic from normal memory loss in the elderly population. Our objective was to assess whether hippocampal atrophy confounds measurements of hippocampal activation in subjects with mild cognitive impairment (MCI). METHODS Twenty(More)
Radiologists play an important role in evaluation of geriatric trauma patients. Geriatric patients have injury patterns that differ markedly from those seen in younger adults and are susceptible to serious injury from minor trauma. The spectrum of trauma in geriatric patients includes head and spine injury, chest and rib trauma, blunt abdominal injury,(More)
OBJECTIVE The purpose of this study was to examine the diagnostic efficacy of hippocampal volumetry and the Mini-Mental State Examination (MMSE) in differentiating amnestic mild cognitive impairment from the normal changes of aging. SUBJECTS AND METHODS The conditions of healthy older persons (n = 17) and persons with amnestic mild cognitive impairment (n(More)
Computed tomography (CT) imaging of the kidney, ureter, and bladder permit accurate and prompt diagnosis or exclusion of traumatic injuries, without the need to move the patient to the fluoroscopy suite. Real-time review of imaging permits selective delayed imaging, reducing time on the scanner and radiation dose for patients who do not require delays.(More)
PURPOSE Incidental thyroid nodules are common on CT. Variability in management recommendations for these nodules due to a lack of accepted CT base guidelines has not been demonstrated. METHODS Consecutive CT cervical spine radiology reports describing thyroid nodules performed in an emergency department from January 1, 2009, to December 31, 2011, were(More)
Diaphragmatic hernias are common, and although frequently incidental, recognition of both benign and life-threatening manifestations of diaphragmatic hernias is necessary to guide appropriate management. Congenital fetal diaphragmatic hernias, traumatic diaphragmatic rupture, and large symptomatic Bochdalek, Morgagni, and hiatal hernias are typically(More)
PURPOSE To assess the utility of selective external iliac artery (EIA) angiography and the frequency of injury to branches of the EIA in cases of blunt pelvic trauma. MATERIALS AND METHODS A retrospective review of pelvic angiograms in 66 patients with blunt pelvic trauma was conducted over a 12-month period. Pelvic and femur fracture patterns were(More)
Penetrating transmediastinal injuries (TMIs) are injuries that traverse the mediastinum. These injuries are most commonly caused by firearms and knives. The investigation and management algorithms for TMI have undergone changes in recent years due to increasing evidence that computed tomography (CT) in useful in the evaluation of hemodynamically stable TMI(More)
W275 Angiomyolipoma is the most common benign renal mesenchymal neoplasm arising from the perivascular epithelioid cells (also known as PEComas) and contains a variable proportion of blood vessels, smooth muscle, and adipose tissue [1]. Angiomyolipoma can degenerate into a malignant form known as epithelioid angiomyolipoma; this rare subtype does not(More)
