    Digital subtraction angiography (DSA) provides excellent early arterial images of the celiac artery, comparable to conventional angiography for evaluating liver, pancreas, and spleen lesions. DSA is a suitable alternative for most patients.

    Area of Science:

    • Radiology
    • Medical Imaging
    • Interventional Radiology

    Background:

    • Celiac trunk angiography is crucial for diagnosing hepatic, pancreatic, and splenic pathologies.
    • Conventional angiography has limitations in image quality and radiation exposure.

    Purpose of the Study:

    • To evaluate the efficacy of digital subtraction angiography (DSA) compared to conventional arteriography for celiac trunk imaging.
    • To determine if DSA is a suitable substitute for conventional angiography in evaluating abdominal visceral arteries.

    Main Methods:

    • Sixty patients underwent intraarterial DSA of the celiac artery.
    • Twenty patients also had conventional arteriography for direct comparison.
    • Image quality was assessed across arterial, parenchymal, and venous phases.

    Main Results:

    • DSA provided excellent early arterial phase images, free from bone superimposition and artifacts.
    • Venous phases, including portal system imaging, were good with DSA, comparable to conventional methods.
    • Late arterial and parenchymal phases were less definitive with DSA than conventional angiography.

    Conclusions:

    • DSA is a suitable substitute for conventional angiography in most celiac trunk imaging scenarios.
    • DSA offers advantages in early arterial phase imaging and venous phase visualization.
    • Postprocessing techniques effectively mitigated artifacts and respiratory motion in DSA studies.
