    Area of Science:

    • Radiology
    • Medical Imaging
    • Pharmacology

    Background:

    • Peripheral arteriography is crucial for diagnosing vascular diseases.
    • Iopamidol is a non-ionic contrast medium used in medical imaging.
    • Patient comfort during contrast-enhanced procedures is a significant factor.

    Purpose of the Study:

    • To evaluate the safety and patient-reported discomfort of iopamidol during peripheral arteriography.
    • To compare the tolerability of iopamidol with methylglucamine diatrizoate containing lidocaine.

    Main Methods:

    • Phase I clinical study involving ten patients undergoing peripheral arteriography.
    • Utilized objective and subjective assessments for discomfort.
    • Included physical examinations, chemical tests, ECGs, and pressure recordings.

    Main Results:

    • Minimal objective evidence of pain was observed.
    • Patients reported minor discomfort and a warm sensation during iopamidol injections.
    • Five patients noted significantly less discomfort compared to previous arteriography with methylglucamine diatrizoate.
    • Excellent opacification of peripheral arteries was achieved.
    • Iopamidol was confirmed safe through various clinical and physiological tests.

    Conclusions:

    • Iopamidol is a safe and well-tolerated contrast agent for peripheral arteriography.
    • Iopamidol offers improved patient comfort compared to older contrast agents.
    • The study supports the use of iopamidol for enhanced peripheral artery imaging.
