BACKGROUND Obtaining diagnostic CT image quality with ultra-low radiation dose in young children with congenital heart disease remains challenging. OBJECTIVE We evaluated the feasibility and image quality of prospectively electrocardiogram (ECG)-triggered high-pitch spiral acquisition with iterative reconstruction for pediatric cardiovascular CT(More)
OBJECTIVE To assess the value of electron beam CT (EBCT) in the diagnosis of aortic intramural hematoma (AIH). METHODS Twenty-five patients who complained of acute chest and back pain were scanned with an EBCT scanner (Imatron C-150) using contrast-enhanced continuous volume scanning (CVS) for establish the diagnosis of AIH. RESULTS Seven patients were(More)
To evaluate the diagnostic accuracy of transluminal attenuation gradient (TAG) for stenosis severity of calcified lesions assessed by coronary computed tomography angiography (CCTA). One hundred seven patients who underwent CCTA and coronary angiography (CAG) were enrolled. TAGs of 309 major epicardial coronary arteries were measured. The impact of plaque(More)
RATIONALE AND OBJECTIVES To evaluate the diagnostic accuracy, image quality, and radiation dose of prospective electrocardiogram (ECG)-triggered high-pitch dual-source computed tomography (DSCT) in infants and young children with complex coarctation of the aorta (CoA). MATERIALS AND METHODS Forty pediatric patients aged < 4 years with suspected CoA(More)
BACKGROUND Aortic dissection is a lift-threatening medical emergency associated with high rates of morbidity and mortality. The incidence rate of aortic dissection is estimated at 5 to 30 per 1 million people per year. The prompt and correct diagnosis of aortic dissection is critical. This study was to compare the ascending aortic image quality and the(More)
RATIONALE AND OBJECTIVES To assess the impact of low-concentration contrast medium on vascular enhancement, image quality, and radiation dose of coronary computed tomography (CT) angiography (CCTA) by using prospectively electrocardiography (ECG)-triggered high-pitch spiral acquisition with low tube voltage in combination with iterative reconstruction. (More)
BACKGROUND Both low tube voltage and sinogram-affirmed iterative reconstruction (IR) techniques hold promise to decrease radiation dose at coronary CT angiography (CCTA). The increased iodine contrast at low tube voltage allows for minimizing iodine load. OBJECTIVE To assess the effect of reduced x-ray tube voltage, low iodine concentration contrast(More)
Gorham-Stout syndrome (GSS), also known as Gorham-Stout disease, massive osteolysis, disappearing bone disease or phantom bone, is a rare disorder of the musculo-skeletal system. It most commonly involves the skull, shoulder and pelvic girdle. Histological examination reveals a progressive osteolysis always associated with an angiomatosis of blood vessels(More)
Endovascular stent-graft implantation technique is a newly developed, effective and less invasive method in treating thoracic aortic dissection (TAD). Our study was designed to further verify the feasibility, the efficacy, and safety of this technique. We present a 4-year follow-up report of endovascular stent-graft treatment over 36 cases of acute TAD(More)
