    Digital subtraction angiography effectively visualizes the vena cava in patients. This method uses less contrast and fewer films, reducing costs compared to conventional angiography.

    Area of Science:

    • Radiology
    • Medical Imaging

    Background:

    • Vena cava imaging is crucial for diagnosing various clinical conditions.
    • Conventional angiography techniques can be invasive and costly.

    Purpose of the Study:

    • To evaluate the efficacy of digital subtraction angiography (DSA) for visualizing the vena cava.
    • To compare DSA with conventional large film angiography.

    Main Methods:

    • Digital subtraction angiography was performed on 74 patients.
    • Conventional large film angiography was repeated in 28 of these patients for comparison.

    Main Results:

    • Digital subtraction angiography proved suitable for demonstrating the vena cava.
    • Repeat examinations with conventional angiography provided no significant additional clinical information.

  • Electronic contrast enhancement allowed for lower contrast concentrations.
  • Selective film usage further reduced examination costs.

    • Conclusions:

    • Digital subtraction angiography is an effective and cost-efficient method for vena cava visualization.
    • DSA offers comparable or superior diagnostic information to conventional angiography with reduced resource utilization.
