OBJECTIVES To evaluate the diagnostic value of diffusion-weighted magnetic resonance imaging (DWI) for the characterization of hepatocellular carcinoma (HCC) and dysplastic nodule (DN) in cirrhotic liver, compared with contrast material-enhanced magnetic resonance imaging (CE-MRI). METHODS A total of 54 patients with 40 HCC and 19 DN lesions were included(More)
BACKGROUND AND AIM The presence of microvascular invasion (MVI) is an independent risk factor affecting recurrence-free survival following surgical treatment for small hepatocellular carcinoma (HCC). Our aim in this study was to investigate whether diffusion-weighted imaging (DWI) could be useful in predicting MVI for small HCC. METHODS Breath-hold DWI(More)
OBJECTIVES Bicuspid aortic valve, characterized by valve malformation and risk for aortopathy, displays profound alteration in systolic aortic outflow and wall shear stress distribution. The present study performed 4-dimensional flow magnetic resonance imaging in patients with bicuspid aortic valve with right-left cusp fusion, focusing on the impact of(More)
BACKGROUND Hydrocephalus results from inadequate passage of cerebrospinal fluid (CSF) from its point of production within the cerebral ventricles to its point of absorption into systemic circulation. AIMS The objective of this study was to investigate the disorders of CSF absorption by arachnoid villi during the different phases of hydrocephalus. (More)
1. Multidrug resistance is the major obstacle to successful cancer chemotherapy. Circumventing multidrug resistance therefore represents a high priority for clinical anti-cancer treatment. Among many reversal strategies, antisense oligodeoxynucleotides may offer a molecular targeting tool for overcoming cellular multidrug resistance. 2. Two 17-mer(More)
 The preoperative diagnosis of a cecal perforation associated with Salmonella infection as a cause of abdominal-wall necrotizing fasciitis (AWNF) is clinically difficult. Computed tomography of the abdomen is helpful, and can detect the combined presence of a pneumoscrotum and pneumoperitoneum. Its presence indicates a patent processus vaginalis, which acts(More)
A symptomatic Meckel's diverticulum (MD) may manifest as an intestinal obstruction secondary to a volvulus. We describe a case of a meconium-impacted MD associated with inflammatory adhesions to adjacent viscera that presented as an intestinal obstruction in a 4-h-old infant secondary to an ileal volvulus with resultant infarction of the diverticulum and(More)
AIM To retrospectively evaluate the computed tomography (CT)/magnetic resonance imaging (MRI) imaging features of epithelioid angiomyolipoma of the liver (Epi-HAML), with pathology as a reference. METHODS The CT/MRI findings (number, diameter, lobar location, and appearance of lesions) in a series of 10 patients with 12 pathologically proven epithelioid(More)
Electromagnetic thermotherapy has been extensively investigated recently and may become a new surgical modality for a variety of medical applications. It applies a high-frequency alternating magnetic field to heat up magnetic materials inserted within the human body to generate tissue coagulation or cell apoptosis. Using a new procedure with dual-row needle(More)
Cancer-associated acute disseminated intravascular coagulation is rare in colorectal cancer, but is rapidly fatal when present. We present a case of a 79-year-old male who developed acute disseminated intravascular coagulation one month after receiving Hartmann's procedure for his rectal cancer. Peripheral blood showed leucoerythroblastosis while marrow(More)
