简要总结
This is a Phase IV multicenter, open-label study and is being implemented in order to assess diagnostic image quality of MDCTA in subjects undergoing computed tomography angiography (CTA) of the thoraco-abdominal aorta, and the carotid, pulmonary and peripheral arteries with IOMERON.
详细描述
This is a Phase IV multicenter, open-label study and is being implemented in order to assess diagnostic image quality of MDCTA in subjects undergoing computed tomography angiography (CTA) of the thoraco-abdominal aorta, and the carotid, pulmonary and peripheral arteries with IOMERON. The hypothesis is that IOMERON used at a high concentration will provide good diagnostic image quality. The Investigators will also function as readers and evaluate the images on-site. Efficacy analysis will be based on the on-site evaluations.
Imaging conditions will be representative of those used in routine clinical practice. The study will be conducted at approximately 10-20 sites in China. Each site may enroll approximately 40 subjects in this study. Approximately 400 subjects will be enrolled in order to obtain 360 evaluable subjects who undergo elective MDCTA of the thoraco-abdominal aorta, or carotid, pulmonary or peripheral arteries.

干预措施: Iomeron (Other)
结局指标
主要结局
Number of participants with an 3 point scoring system used for assessing diagnostic image quality
时间窗: 2 hours
0 = Insufficient: Impaired image quality precludes adequate diagnostic assessment of vascular abnormalities (stenosis, embolism, dissection, etc.) because of severe noise, or severe artifacts, or insufficient contrast enhancement. 1. = Adequate: Image quality is sufficient for adequate diagnostic assessment of vascular abnormalities (stenosis, embolism, dissection etc.), even in presence of minimal noise, or minimal artifacts and sufficient contrast enhancement. 2. = Good: Image quality allows adequate, complete and rapid diagnostic assessment of vascular abnormalities (stenosis, embolism, dissection etc.) with absent or very minimal noise, or absent or very minimal artifacts, and optimal contrast enhancement.
Number of participants with an 3 point scoring system used for visual assessment of contrast enhancement and delineation of vascular structures/abnormalities
时间窗: 2 hours
0 = Insufficient: Generally poor enhancement and delineation of major vascular structures/abnormalities (e.g. major endoleaks, aneurysms, bleeding, etc.). 1. = Adequate: Sufficient enhancement and delineation of vascular structures/abnormalities (e.g. small bleeding, endoleaks, etc). 2. = Good: Optimal enhancement and complete delineation of vascular structures/abnormalities (e.g. small bleeding, endoleaks, etc).
次要结局
- Comparing number of participants undergoing x-ray angiography as the truth standard with the diagnostic performance of MDCTA diagnosis using a two point scoring system(2 hours)
