The inter-rater and intra-rater reliability of three
cardiac gated carotid imaging techniques (cineFSE,
prospectively gated FSE, and cineGRE) were determined by
comparison of repeated manual tracings of common carotid
area in ten healthy subjects. All sequences reflected
highly repeatable manual measures (inter-rater ICC ≥
0.85 in all cases). Minimum detectable difference (MDD)
was calculated for each sequence to determine its
ability to characterize changes in carotid distension.
The cineFSE images produced the lowest MDD (5.8 mm
2
)
compared to prospective FSE (7.4 mm
2
) and
cineGRE (7.8 mm
2
). Additionally, the
scan-rescan reliability of the cineFSE technique was
assessed.
