Lesions of skin and brain: modern imaging of the neurocutaneous syndromes MS Pont and AD Elster The neurocutaneous syndromes, or phakomatoses, are a diverse group of disorders affecting the skin and CNS. This review highlights some important but lesser known aspects of the more common phakomatoses while concentrating on rarer and more recently discovered syndromes. The roles of newer imaging techniques such as contrast-enhanced MR […]

Persistence of Cerebral Blood Flow after Brain Death W. Mel. Flowers, JR., MD, Bharti R. Patel, MD, Department of Radiology, Division of Nuclear Medicine, University of Mississippi Medical Center, Jackson Persistent cerebral blood flow occasionally confounds confirmatory tests for brain death and results in the anguish of delayed diagnosis, unnecessary use of expensive resources, and loss of transplant opportunities. We reviewed the […]

Thyroid nodules: When to biopsy Fauzia Q. Vandermeer, MD and Jade Wong-You-Cheong, MD Abstract: Thyroid nodules are increasingly found incidentally on cross-sectional imaging studies performed for nonthyroid indications. The challenge is to diagnose the minority of malignant nodules while limiting the impact on the large majority of patients with benign nodules. This article reviews the epidemiology of thyroid cancer, […]

Sonographic Features of Benign Thyroid Nodules Interobserver Reliability Jeffrey R. Wienke, MD, Wui K. Chong, MD, Julia R. Fielding, MD, Kelly H. Zou, PhD and Carol A. Mittelstaedt, MD Objective. To prospectively determine the sonographic findings of nodular hyperplasia of the thyroid, to compare these with reported findings associated with malignancy, and to assess interobserver reliability. Methods. Seventy thyroid nodules were scanned, […]

Significance of Incidental Thyroid Lesions Detected on CT Sanjay K. Shetty1,2, Michael M. Maher1, Peter F. Hahn1, Elkan F. Halpern1 and Suzanne L. Aquino1 OBJECTIVE. The purpose of our study was to determine the prevalence of malignancy in incidental abnormalities of the thyroid gland detected on CT and to determine the relative accuracy of characterizing these abnormalities on CT as compared with […]

Pediatric Cervical Spine: Normal Anatomy, Variants, and Trauma

  Emergency radiologic evaluation of the pediatric cervical spine can be challenging because of the confusing appearance of synchondroses, normal anatomic variants, and injuries that are unique to children. Cervical spine injuries in children are usually seen in the upper cervical region owing to the unique biomechanics and anatomy of the pediatric cervical spine. Knowledge […]

The Infant Skull: A Vault of Information

  The art of interpreting skull radiographs is slowly being lost as trainees in radiology see fewer plain radiographs and depend more heavily on computed tomography and magnetic resonance imaging. Nevertheless, skull radiographs still provide significant information that is helpful in finding pathologic conditions and appreciating their extents. Abnormalities in the skull may be reflected […]
