Brain MR angiography using automatic clipping techniques: Evaluation of workflow improvement compared to manual
Introduction:
Manual clipping in brain MR angiography (MRA) is time-consuming and depends on operator experience. This study aimed to evaluate the effectiveness of an automatic clipping function (AutoClip) in improving workflow efficiency and maintaining image quality across different experience levels.
Methods:
Thirty brain MRA datasets were processed by three technologists with 12, 5, and 1 years of MRI experience using both manual and automatic clipping. Processing time was measured, and image quality was visually assessed using a five-point scale for major intracranial arteries.
Results:
AutoClip significantly reduced processing time for all operators, with the largest reduction observed in the least experienced operator. Visual assessment showed comparable image quality between manual and automatic methods, independent of experience level.
Conclusion:
AutoClip may maintain diagnostic image quality while substantially reducing post-processing time, particularly benefiting less-experienced operators and potentially improving overall workflow efficiency.
Implications For Practice:
The AutoClip function could enhance workflow efficiency and standardize MRA post-processing across operators with varying experience levels.
