PURPOSE To determine predictors of deep venous thrombosis (DVT) in the lower extremities and pulmonary arterial thromboembolism (PE) after total knee arthroplasty (TKA), we evaluated the incidence of these events using multislice computed tomography (CT). METHODS 54 subjects (10 males, 53-81 years old, the first consecutive 25 receiving anticoagulant(More)
OBJECTIVES We detected non-calcified plaques (NCPs) in the coronary arteries using multislice computed tomography (MSCT) in order to determine the predictors of NCPs using logistic regression models. METHODS Two hundred and forty-two consecutive subjects (141 males; overall age range, 17-91 years old) underwent enhanced electrocardiogram-gated MSCT to(More)
PURPOSE We frequently observe fat replacement (FR) of the anterior wall of the right ventricular myocardium (RVM), but its epidemiological significance is not clear. METHODS AND MATERIALS 49 consecutive subjects (28 males, 36-83 years old, median 67) underwent enhanced ECG-gated multislice CT (Light speed ultra 16, General Electrics, WI) and we(More)
We report the successful surgical treatment of a pseudoaneurysm of the ascending aorta in a 45-year-old man who underwent surgical closure of a ventricular septal defect at the age of 5. A computed tomography scan ordered for the investigation of a pulmonary mass happened to detect a pseudoaneurysm (20 mm diameter). The pseudoaneurysm protruded anteriorly(More)
OBJECTIVE We reviewed long-term survival among hosts in 3 consecutive series of a rhesus monkey-baboon orthotopic cardiac xenotransplantation model with reference to host immune response, including the effectiveness in preventing rejection and limiting toxicity concerning infection, to evaluate specific immunosuppressive regimens for long-term outcomes.

Lower tube voltage has advantages for CT angiography, such as improved contrast To evaluate the image quality of low-voltage (70 kV) CT for congenital heart disease and the ability of sinogram-affirmed iterative reconstruction to improve image quality. Forty-six children with congenital heart disease (median age: 109 days) were examined using dual-source(More)
OBJECTIVE To demonstrate the utility of multislice computed tomography (MSCT) in the evaluation of direction, location, and size of shunt flow in congenital heart disease. BACKGROUND Transthoracic and transesophageal echocardiography, magnetic resonance imaging, and conventional angiography has been used to evaluate congenital heart disease; however, some(More)
Improved time resolution using dual-source computed tomography (DSCT) enabled adaptation of electrocardiography (ECG)-gated cardiac CT for children with a high heart rate. In this study, we evaluated the ability of ECG-gated DSCT (ECG-DSCT) to depict the morphological ventricular features in patients with congenital heart disease (CHD). Between August 2006(More)
To reduce the right ventricular (RV) pressure and the pressure gradient between the RV and the pulmonary artery (PA) in Tetralogy of Fallot (TOF) with small pulmonary annulus, it is inevitable to enlarge the small annulus by incising and patching from RV to PA via PA annulus. If the anomalous coronary artery exists in the RV outflow tract, the procedure can(More)
