Sequential 2D inflow NMR venography shows promise for evaluating proximal venous systems. While effective for iliac and femoropopliteal veins, further improvements are needed for diagnostic imaging of calf veins.

Area of Science:

  • Medical Imaging
  • Vascular Medicine
  • Diagnostic Techniques

Background:

  • Deep vein thrombosis (DVT) is a significant vascular condition.
  • Accurate venous anatomy and pathology assessment is crucial for DVT diagnosis and management.
  • Current imaging modalities may have limitations in specific venous segments.

Purpose of the Study:

  • To evaluate the diagnostic utility of Sequential 2D inflow NMR (SDI) venography.
  • To assess the capability of SDI venography in defining venous anatomy and pathology.
  • To investigate SDI venography's effectiveness in both healthy subjects and patients with deep vein thrombosis.

Main Methods:

  • Sequential 2D inflow NMR (SDI) venography was performed.
  • The study included five healthy subjects and five patients with documented deep vein thrombosis.

  • SDI venograms were independently graded by two observers using a diagnostic scale.

    • Main Results:

    • All iliac and femoropopliteal SDI venograms were found to be diagnostic.
    • In contrast, only one out of nine calf SDI venograms achieved a diagnostic classification.
    • SDI venography demonstrated diagnostic potential for the proximal peripheral venous system.

    Conclusions:

    • Sequential 2D inflow NMR venography is a promising method for assessing the proximal peripheral venous system.
    • Current SDI venography strategies require improvement for effective imaging of calf veins.
    • Further research into optimized imaging strategies is necessary for comprehensive lower extremity venous assessment.
