Patient safety has become an important issue due to medical errors. Some health care systems use Radio Frequency Identification (RFID) to identify patients during medical procedures. However, the RFID data readability especially depends upon the environment, an investigation of data reliability and signal loss is essential to making an effective deployment(More)
Cardiovascular disease is the primary cause of morbidity and mortality in the western world. Complex hemodynamics plays a critical role in the development of aortic dissection and atherosclerosis, as well as many other diseases. Since fundamental fluid mechanics are important for the understanding of the blood flow in the cardiovascular circulatory system(More)
PURPOSE To solve the problem of the basal descent movement in quantification of the regional left ventricular (LV) myocardial wall thickness (WTh) and wall thickening (%WT) in short-axis (SA) cine MRI for effectively assessing the regional wall motion of LV myocardium. MATERIALS AND METHODS LV long-axis tagged MRI and SA cine MRI were performed to(More)
BACKGROUND Olfactory bulb (OB) volume has been shown to be an indicator of olfactory function. However, few studies have been done in Asia to investigate the influence of different disorders on OB volume. METHODS Data from patients with posttraumatic anosmia were collected in our department. Their olfactory thresholds were assessed by the phenyl ethyl(More)
PURPOSE To effectively perform quantification of brain normal tissues and pathologies simultaneously, independent component analysis (ICA) coupled with support vector machine (SVM) is investigated and evaluated for effective volumetric measurements of normal and lesion tissues using multispectral MR images. MATERIALS AND METHODS Synthetic and real MR data(More)
OBJECTIVE A prospective study was performed to evaluate the incidence, clinical manifestations and outcome of ductus arteriosus aneurysm (DAA) in full-term neonates. BACKGROUND Ductus arteriosus aneurysm has been considered to be a rare congenital lesion and a potentially fatal abnormality. METHODS A total of 548 full-term neonates received(More)
BACKGROUND Primary nasal natural killer (NK)/T-cell lymphoma is the most common cellular subtype seen in nasal lymphomas. It is rare in the Western population but occurs more frequently in Asia, South America, and Mexico. The purpose of this study was to describe the computed tomography (CT) and magnetic resonance (MR) imaging findings of primary nasal(More)
BACKGROUND/AIMS To develop a new magnetic resonance cholangiopancreatography technique for patients who cannot hold their breath or breathe regularly and fail to be successfully examined with conventional magnetic resonance cholangiopancreatography methods. METHODOLOGY Within a one-year period, 15 patients including 6 children and 9 adults were studied.(More)
Blindly separating images prior to applying tissue-contrast-enhancing algorithms shows clear improvements over current techniques. Imaging using magnetic resonance (MR) provides superior soft-tissue contrast resolution over other screening techniques used in medicine. Analysis of the images is generally performed by spatial-domain-analysis-based processing(More)
Subdural hematoma (SDH) of the spine following intracranial hemorrhage is extremely rare. We present a 35-year-old woman who suffered from headache and dizziness initially, and then lower back pain, lower limb weakness and paraparesis gradually developed within 1-2 weeks. Magnetic resonance imaging revealed intracranial and spinal SDH. No vascular(More)
