Renal fusion anomalies, in which both kidneys are fused togeher in early embyronic life, are rarely encountered. Once a fused kidney is diagnosed or suspected, further laboratory and imaging evaluation should be performed to assess the status of the kidneys and to look for treatable causes of renal pathology. The early dignosis of potential complications that can accompany this anomaly must be ...

Various biliary pathologic conditions can lead to acute abdominal pain. Specific diagnosis is not always possible clinically because many biliary diseases have overlapping signs and symptoms. Imaging can help narrow the differential diagnosis and lead to a specific diagnosis. Although ultrasonography (US) is the most useful imaging modality for initial evaluation of the biliary system, multidet...

INTRODUCTION The characterization of urinary calculi using noninvasive methods has the potential to affect clinical management. CT remains the gold standard for diagnosis of urinary calculi, but has not reliably differentiated varying stone compositions. Dual-energy CT (DECT) has emerged as a technology to improve CT characterization of anatomic structures. This study aims to assess the ability...

BACKGROUND AND PURPOSE Some recent studies on radiation lens injuries have indicated much lower dose thresholds than specified by the current radiation protection guidelines. The purpose of this research was to measure the lens dose during brain CT scans with multidetector row CT and to assess methods for estimating the lens dose. MATERIALS AND METHODS With 8 types of multidetector row CT sca...

Eosinophilic granuloma (EG) is a well-recognised benign form of Langerhans-cell histiocytosis. The estimated incidence of EG is 3-4 per million of the population. More patients are children and adolescents between the ages of 1 and 15 years. The value of plain films in the diagnosis of the EG is limited and the extent of the disease is better defined by multidetector CT (MDCT) scanning. MDCT sc...

Advances in cross-sectional imaging, including conventional and helical (spiral) CT and multidetector (MDCT) and MR imaging, now allow detailed evaluation of the anatomy and pathology of the neck and thoracic inlet. The major structures are identified by their appearance and that of contrasting fatty tissue planes surrounding the soft tissues. These structures include the larynx, trachea, thyro...

Rev Esp Cardiol. 2005;58(3):301 301 A 45-year-old male, smoker, and with no other cardiovascular risk factors was hospitalized for an inferior myocardial infarction. Fibrinolysis treatment was administered causing the clinical and electrocardiograph signs to disappear. A contrast-enhanced CT examination using a 16-multidetector CT was performed 3 days later. An atherosclerotic plaque with densi...

OBJECTIVES To evaluate the detection of clinically unsuspected pathologies using 64-slice multidetector computed tomography (CT) of the abdomen in patients with flank pain. The presence of significant incidental findings (those warranting immediate management) was also correlated with that of urolithiasis, to assess potential changes of management. PATIENTS AND METHODS The study included 899 ...

Magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) play a critical role in diagnosing aortic disease such as aortic dissection and aneurysm. Additionally, the advent of contrast-enhanced MRA has allowed MRA to advance markedly and several new imaging techniques to emerge as well. While computed tomography (CT) angiography using multidetector-row CT is a significant innova...
