Area of Science:

  • Radiology
  • Medical Imaging
  • Magnetic Resonance Imaging

Background:

  • Whole-body MR angiography (WB-MRA) is crucial for assessing vascular diseases.
  • Existing WB-MRA techniques can be time-consuming and may require multiple table movements.
  • Optimizing acquisition speed and patient comfort is essential for clinical application.

Purpose of the Study:

  • To develop and evaluate a novel rolling table platform with an integrated surface coil for efficient whole-body MR angiography.
  • To assess the feasibility and diagnostic quality of the AngioSURF system for imaging the entire arterial tree.

Main Methods:

  • A rolling table platform (AngioSURF) with an integrated surface coil was developed and mounted on a Siemens Symphony System.
  • Whole-body MR angiography was performed using a 3D-FLASH sequence with a paramagnetic contrast agent in three volunteers and one patient.

  • Data acquisition involved five successive data sets, with rapid table repositioning, achieving a total acquisition time of 72 seconds.

    • Main Results:

    • The AngioSURF system demonstrated excellent handling without complications in all four cases.
    • High-quality MR angiography images were obtained, allowing for detailed assessment of vascular territories.
    • The technique successfully visualized the arterial system from supraaortic vessels to distal arteries.

    Conclusions:

    • The AngioSURF rolling table platform with an integrated surface coil offers a fast and effective solution for diagnostic whole-body MR angiography.
    • This technique significantly reduces acquisition time to 72 seconds, improving patient throughput and experience.
    • AngioSURF enables comprehensive visualization of the arterial vasculature, supporting clinical diagnosis.
