OBJECTIVES For the evaluation of skeletal age, the methods of Greulich-Pyle and Tanner-Whitehouse are generally used in clinical practice. Our investigation was undertaken to determine whether the ultrasonographic version of the Greulich-Pyle atlas is capable of assessing skeletal age. If so, we aimed to describe the standards for the ultrasonographic(More)
BACKGROUND AND PURPOSE Although essential tremor (ET) is one of the most common movement disorders, its pathogenesis remains obscure. The ventral intermediate nucleus of the thalamus (VIM nucleus) is suggested to play an important role in the occurrence of disease. In this study, the authors investigated the presence of biochemical or metabolic alterations(More)
Muscle herniation can be defined as protrusion of a portion of muscle through an acquired or congenital defect of enclosing fascia. Although it is usually a cosmetic problem, it can lead to local pain and tenderness after prolonged exertion. In this report, we present a case of flexor digitorum superficialis muscle herniation in a 58-year-old man. The(More)
Early-enhancing areas that are perfusion abnormalities rather than tumor deposit are sometimes encountered on arterial dominant-phase images in multisection dynamic magnetic resonance imaging. Focal sparing in diffusely fatty liver is also a well recognized entity. However, both conditions occasionally create problems in the diagnosis of hepatic mass(More)
We present the case of a late-onset urinoma in a 47-year-old man with a history of right ureterolithotomy performed 6 months previously, following 2 unsuccessful attempts at extracorporeal shock wave lithotripsy. The ipsilateral kidney was nonfunctional and hydronephrotic. The urinoma did not show enhancement on contrast-enhanced CT and intravenous(More)
PURPOSE To test if the apparent diffusion coefficient (ADC) values reflect the ultrastructural changes of normal appearing white and gray matter with advancing age. MATERIALS AND METHODS We selected 45 patients with normal MRI and DW imaging findings. DW and MRI imaging was performed and for each patient the average ADC on trace images of the frontal and(More)
