ECT成像的基本原理:放射性药物引入人体,经代谢后在脏器内ECT外或病变部位和正常组织之间形成放射性浓度差异,将探测到这些差异,通过计算机处理再成像。ECT成像是一种具有较高特异性的功能显像和分子显像,除显示结构外,着重提供脏器与端正变...

Whole-Body Ct Scan Increases Chance Of Survival In Severely Injured PatientsThe Lancet
In 1973, AmericanRobert Ledleydevelopeda whole-body scannerthat could image other organs, blood vessels and, of course, bones. Modern scanners are faster, provide better resolution, and most important, do it with less radiation exposure. There are even mobile scanners. Modern...
To investigate the performance of dynamic 3D diuretic renal scintigraphy using a hybrid whole body CZT SPECT/CT for the evaluation of acute ureteric obstruction in patients with urinary stone disease. 20 patients who presented to the Emergency Department
Fortunately, I had insurance but still had to pay a high out of pocket. I was in there for pains in my lower abdomen. They scanned my stomach/chest area not even my whole body. Was in the ER for 6 hours, one pain medicine. Did a pregnancy test on me even though I could have to...

The article presents a feasibility study of non-electrocardiography (ECG)-gated low peak kilovoltage (kVp) scan of the whole chest after coronary computed tomography (CT) angiography. It highlights the accuracy of coronary CT in coronary artery disease evaluation. An overview on the comparison betwe...
