计算机断层扫描肺血管造影(computed tomography pulmonary angiogram;CTPA/CTPE)是一种常见的排除肺栓塞(PE)的诊断检查。 执行高诊断质量的CTPA有两种主要方法: 团注测试:注入少量的“测试”造影剂,并采集感兴趣区域的连续轴向切片,以计算峰值对比度增强的时间并确定最佳扫描延迟时间;...
An angiogram is a specific type ofCT scanwith contrast. In a CT angiogram the contrast is timed so that it will highlight either the arteries or veins (venogram) of interest. What is a CT angiography used for? A computerized tomography (CT) coronary angiogram isan imaging test that looks ...
Diagnosis of ischemia-causing coronary stenoses by noninvasive fractional flow reserve computed from coronary computed tomographic angiograms. Results from the prospective multi-center DISCOVER-FLOW (Diagnosis of Ischemia-Causing Stenoses Obtained Via Noninvasive Fractional Flow Reserve) study. J Am Coll ...
Subsequent pulmonary embolism: risk after a negative helical CT pulmonary angiogram--prospective comparison with scintigraphy. PURPOSE: To determine whether a helical computed tomographic (CT) scan that is negative for pulmonary embolism (PE) is a sufficiently reliable criterion to... LR Goodman,RJ Li...
Reduced intravenous iodinated contrast dose for multi-body part exams Faster total exam acquisition times CT Coronary Angiograms, CT Angiograms of the Thoracic Aorta and CT Cardiac Exams Now Availabe at TSJI Utilizing a new GE Discovery PET/CT scanner we will now provide the full spectrum of ...
Angiogram risks As with any procedure that involves X-rays, an angiogram exposes you to radiation. Complications from an angiogram are rare. However, potential risks include: Injury to the catheterized artery An allergic reaction to the medication or contrast agent ...
What to Expect During Your CT Angiogram The exact procedure of your CT angiography will vary depending on your specific condition. Generally, you can expect the procedure to begin with a clinician placing you on the exam table and administering the contrast material through an IV in your arm or...
Contrast timing optimization of a two-volume dynamic CT pulmonary perfusion technique Article Open access 17 May 2022 Depiction of mosaic perfusion in chronic thromboembolic pulmonary hypertension (CTEPH) on C-arm computed tomography compared to computed tomography pulmonary angiogram (CTPA) Article Op...
ObjectivesMulti-modal imaging, mainly non contrast CT brain (NCCT) with CT angiogram (CTA) with or without CT perfusion (CTP) is essential for the rapid evaluation of stroke patients, with the ultimate goal being accurate diagnosis and timely management of patients.1 These imaging protocols are ...
