Eligibility Criteria
-----------------
Inclusion Criteria: Enroll a patient in this study if the patient meets the following 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 peripheral DSA for the diagnosis and/or treatment (PTA) of PAOD. Exclusion Criteria: Exclude a patient from this study if the patient does not fulfill the inclusion criteria, or if any of the following conditions are observed: 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 the investigational products; Has a history of severe congestive heart failure [class IV in accordance with the classification of the New York Heart Association (NYHA)] Was previously entered into this study or received an investigational compound within 30 days before admission into this study; Has a history of hypersensitivity to iodinated contrast agents; Has renal impairment (eGFR <60 mL/min/1.73 m2, calculated using the Modification of Diet in Renal Disease [MDRD] study equation , ); 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 postdose follow-up examinations.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Level of Pain in the Lower Extremities Scored by the Participants on the Visual Analog Scale Following Intraarterial Administration of ISOVUE-250 or VISIPAQUE 270 in Peripheral DSA. | Visual Analog Scale: Patients were asked to mark on a 10 centimeter line where their pain was in the lower extremity of interest, in relation to the 2 extremes: no pain (0) on the far left and worst pain (10) on the far right. Pain Severity Scale: (0) None = VAS Score 0; (1) Mild = VAS Score 1-3; (2) Moderate = VAS Score 4-6; (3) Severe = VAS Score 7-10. Patients were assessed immediately prior to injection and again immediately following injection. | Immediately prior to power injection run and again immediately following power injection run | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The Number of Participants With Motion Artifacts Following Intraarterial Administration of ISOVUE-250 or VISIPAQUE 270 in Peripheral DSA. | Using the following 5-point scale, the Investigator reviewed the images for motion artifact in vessels distal to the knee: 0 = None; 1 = Mild, not significant; 2 = Significant, but correctable; 3 = Degrades image quality; 4 = Images uninterpretable. | Immediately postdose | 
| The Number of Participants Requiring Repeat Injection(s) Following Intraarterial Administration of ISOVUE-250 or VISIPAQUE 270 in Peripheral DSA. | The Investigator assessed the images and recorded the number of repeat power injections required due to motion artifacts for each participant. | Immediately postdose |
