After drawing blood and running a CT scan, the doctor had questions for me. “What is a typical day like for you” “I am a graduate student with a tight schedule that usually keeps me at work late into the night,” I replied. Next, he turned to diet. I paused when this question...
However, the main limitation of micro-CT relates to contrast; as the absorption of X-rays by soft tissues or optical coloured stains is low, this causes difficulties in the simultaneous imaging of tissue structure and in the analysis of gene expression, respectively (Ritman, 2002). In ...

according to the work of van der Giessen et al.38. Crucially, the differences in flow within epicardial vessels between the models informed by MPICTand Murray’s Law affected the computation of FFR, particularly in vessels with borderline lesions of ≈50% stenosis. Risk stratification based on ...
Conclusion Contrast dynamic CT scanning could reflect the blood supply and distribution characters.The appearence of tumor vessels in of great significance for the diagnosis of pheochromocytoma with cercain sensitici-ty and specificity. Thus vascular enhancement feature can be used as another specific ...

CT scan were scheduled every 12 weeks or earlier if clinically indicated. In the case of progressive disease, patients were allowed to continue the treatment if clinical improvement was maintained, and the CT was repeated after 8 weeks to confirm progression. In addition to a RECIST-defined ...
