CT perfusion imaging of the liver of the Technical Research

Angiography and coronary artery reconstruction using post-processing, display the main coronary artery and its branches, and the diagnosis of coronary lesions in patients with 344 262 cases of coronary artery underwent selective coronary angiography. Results: 1223 routine 64-slice spiral CT coronary angiography in 344 patients showed different degrees of coronary stenosis. Conclusion: 64 slice spiral CT for the diagnosis of coronary artery stenosis with high clinical value.

Keywords: Coronaryartery64DRCTDSA today's society, as people's living standard rising, increasing incidence of coronary heart disease, especially in recent years,[link widoczny dla zalogowanych], the incidence of coronary heart disease gradually younger, early detection and treatment of disease can reduce mortality, which coronary artery (the coronary artery) stenosis accurate detection has become an urgent need. Since the inception of 16-slice spiral CT, in particular the use of 64-slice spiral CT, for coronary heart examination provides a new means of it as an economic, rapid, noninvasive,[link widoczny dla zalogowanych], and complement the traditional DSA in imaging has broad application prospects. 1 Materials and methods 1.1 Clinical data collected in this study in our hospital in June 2005 ~ January 2006 asked the clinically diagnosed as coronary heart disease in patients undergoing coronary CTA 1223 cases. Male 616, female 607 cases. Age of 38 years to 82 years, mean age 61 years, with chest epilepsy, chest tightness history of 1172 cases, 966 had history of hypertension. In which 262 patients underwent DSA, male 143 cases, 119 cases of women, ages 44 to 77 years, mean age 60 years. 1.2 Inspection Methods: TOSHIBAAquilion64 spiral cT scanners,[link widoczny dla zalogowanych], fast heart rate, those of oral metoprolol 1 hour before scanning 25rag ~ 50mg. 8O times to control the heart rate / min,[link widoczny dla zalogowanych], scan range from the heart to the apex. Scan for coronary calcium scoring first, the use of retrospectively ECG-gated spiral scanning, the use of high-pressure syringe injection through the right elbow of non-ionic contrast agent (350mgL/m1) 60rnl, injection speed of 3.5 ~ 4.0ml / s , then the same rate of injection of saline 4JDrnl, using Surestar automatic tracking technology,[link widoczny dla zalogowanych], the Department set the threshold of the ascending aorta is a scanning range 190Hu tracheal bifurcation to the liver from the upper edge of breath-hold scan.
