A Multicenter Study of Iomeron®-400 Used With Multi-detector Computed Tomography Angiography (MDCTA)

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.

Inclusion criteria

• Provides written Informed Consent and is willing to comply with protocol requirements
• Is at least 18 years of age.
• Is scheduled to undergo an elective thoraco-abdominal aorta, carotid, pulmonary or peripheral MDCTA examination.

Exclusion criteria

• Is a pregnant or lactating female. Exclude the possibility of pregnancy:

by testing on site at the institution (serum or urine βHCG) within 24 hours prior to the start of investigational product administration, by surgical history (e.g., tubal ligation or hysterectomy),post-menopausal with a minimum 1 year without menses;

• Has any known allergy to one or more of the ingredients of IOMERON or a history of hypersensitivity to iodinated contrast agents;
• Has moderate to severe renal impairment;
• Has received an investigational compound and/or medical device within 30 days before admission into this study;
• Has been enrolled previously to this study
• Has any medical condition or other circumstances which would significantly decrease the chances of obtaining reliable data, achieving study objectives, or completing the study and/or post-dose follow-up examinations.
