- There were 38 participants,
28 men and 10 women,
aged between 21 and 57 years (mean age of 33.5 +/- 10.4 years).
- Regarding the detection of ACL tears (Table 1),
the overall combined sensitivity,
specificity,
positive predictive value,
negative predictive value,
and accuracy were 93%,
85%,
95%,
81% and 91% using 2D-TSE MRI,
and 93%,
80%,
93%,
80% and 89% using 3D-TSE MRI,
respectively.
No significant differences between both techniques were found (Figure 1).
The agreement between both techniques was 0.83 [0.70-0.97].
- Regarding the detection of medial meniscal tears (Table 1),
the overall combined sensitivity,
specificity,
positive predictive value,
negative predictive value,
and accuracy were 83%,
71%,
83%,
71% and 79% using 2D-TSE MRI,
and 85%,
68%,
82%,
73% and 79% using 3D-TSE MRI,
respectively.
No significant differences between both techniques were found (Figures 2 and 3).
The agreement between both techniques was 0.89 [0.77-0.99].
- Regarding the detection of lateral meniscal tears (Table 1),
the overall combined sensitivity,
specificity,
positive predictive value,
negative predictive value,
and accuracy were 54%,
92%,
78%,
79% and 79% using 2D-TSE MRI,
and 58%,
82%,
63%,
79% and 74% using 3D-TSE MRI,
respectively.
No significant differences between both techniques were found.
The agreement between both techniques was 0.74 [0.58-0.92].
- Table 2 shows the sensitivity,
specificity,
and accuracy for both readers readings separately,
as well as the intraobserver agreement comparing both MRI techniques (2D vs.
3D).
No significant differences between both techniques were found.
Table 3 shows the interobserver agreement regarding each feature assessed and each MRI technique used.
