Preliminary Results:
Quantitative analysis
ROIs were successfully measured for 9 subjects.
The mean SD in the white matter parenchyma on conventional T2 PROPELLER was 25.94 ± 6.8,
and “Quiet” T2 PROPELLER was 24.6 ± 5.7.
No significant difference in the mean SD was identified between the two sequences (p = 0.17). The mean SD in the white matter parenchyma on conventional T2 FLAIR PROPELLER (21.94 ± 5.69) was significantly higher in comparison to the “Quiet” T2 FLAIR PROPELLER sequences (18.6 ± 4.8) (p<0.02).
Qualitative analysis
No differences were observed in image quality,
white/grey matter differentiation or blurring perception,
between “Quiet” and conventional techniques for all the patients.
When the overall preference was evaluated no differences were found in all the cases between “Quiet” and conventional sequences.
In only one case the “Quiet” T2 FLAIR PROPELLER was preferred over the conventional T2 FLAIR PROPELLER.
