Objective To compare the accuracy difference between CTA and TCD in diagnosis of intracranial vascular stenosis. Methods 200 patients with suspected intracranial vascular stenosis were selected. All the research object got examination of CTA and TCD within 3 days after attack,and compared the diagnostic...
Abdominal computed tomography (CT) examination revealed multiple tortuous vascular shadows in the paravertebral column and bilateral chest wall areas. To further clarify the diagnosis, thoracic and abdominal computed tomography angiography (CTA) was performed, which showed that the aortic arch and descendin...
Qinglin Zhang2 & Simon Van Gaal3,4 Although previous work has shown that conflict can be detected in the absence of awareness, it is unknown how different sources of conflict (i.e., semantic, response) are processed in the human brain and whether these processes are differently modulated...
Coronary CTA data sets were acquired on a second-generation dual-source CT scanner using retrospectively ECG-gated spiral acquisition or prospectively ECG-triggered axial acquisition mode. Plaque volume and composition (non-calcified, calcified), remodeling index as well as contrast density difference (...
However, a recent discovery has found an ultrahigh-resolution CT scanner that could be capable of overcoming the limitation of conventional CTA in the environment of severe stents orcoronary artery calcification, thus surpassing it’s invasive counterpart. The ultrahigh-resolution CT scanner (UHR-CT)...
(1-4)β-Gal were used to determine the presence of P fimbria by latex agglutination. Approximately 1 × 109CFU of bacteria cultured in broth in a total volume of 10 μL, was mixed with 25 μL PBS and 2 μL latex beads in a 96-well microtiter plate. A granular settling of latex ...

CT coronary angiographyInvasive angiographyTransluminal attenuation gradientThis study evaluated the feasibility of stress 320 detector CT coronary angiography (CTA) derived transluminal attenuation gradient (TAG320) and contrast opacification (CO) difference to detect hemodynamically significant stenoses as ...
Compared with rest CTA, stress CTA demonstrated inferior image quality (Median Likert score 4 vs. 3, P<0.0001) and required a higher mean radiation exposure (3.2 vs. 5.1mSv, P<0.0001). Stress TAG320 and CO difference is less feasible and was not superior in diagnostic performance when ...
