Whole-body three-dimensional MR angiography with a rolling table platform: initial clinical experience

Area of Science:

• Radiology
• Medical Imaging
• Cardiovascular Imaging

Background:

• Peripheral vascular disease (PVD) diagnosis relies on accurate imaging.
• Magnetic Resonance (MR) angiography offers non-invasive visualization of blood vessels.
• Current whole-body MR angiography techniques may have limitations in image quality and patient throughput.

Purpose of the Study:

• To evaluate a novel multi-station three-dimensional (3D) MR angiography technique for whole-body imaging.
• To assess the efficacy of a self-developed rolling table platform with integrated surface coils.
• To determine the diagnostic performance of this technique for detecting lower extremity stenoses.

Main Methods:

• A self-developed rolling table platform integrating surface coils was utilized.
• Multi-station three-dimensional MR angiography was performed for whole-body imaging.
• The technique was evaluated in three volunteers and 10 patients with suspected or known PVD.

Main Results:

• The integrated surface coil provided high signal-to-noise ratios (SNR) and contrast-to-noise ratios (CNR).
• The technique achieved high sensitivity (95.3%) and specificity (95.2%) for detecting significant stenoses (>50% luminal narrowing).
• The rolling table facilitated efficient multi-station data acquisition.

Conclusions:

• The novel rolling table platform with integrated surface coils is effective for whole-body MR angiography.
• This technique demonstrates excellent diagnostic accuracy for significant lower extremity stenoses in PVD.
• The method offers a promising approach for comprehensive vascular assessment.
