Results
Concerning the diagnosis of adenomyosis,
TVUS resulted negative in 61% of cases,
it diagnosed a focal form of adenomyosis in 22% of cases and a diffuse form in 17% of cases while 1.5T MRI risulted negative in 26% of cases,
it diagnosed a focal form of adenomyosis in 30% of cases and a diffuse form in 44% of cases (Fig.9).
Using 1.5T MRI as the gold standard,
TVUS demonstrated a sensitivity of 41%,
a specificity of 67%,
a positive predictive value of 78% and a negative predictive value of 29% (Fig.10),
with a diagnostic accuracy of 47.8% (IC=32.9-63.1).
We then evaluated how the TVUS diagnostic accuracy changes with or without associated leiomyomas or congenital uterine anomalies: regarding the diagnosis of adenomyosis,
without associated findings TVUS demonstrated a sensitivity of 45%,
a specificity of 100%,
a positive predictive value of 100% and a negative predictive value of 33% with a diagnostic accuracy of 57.1% (IC=28.9-82.3),
while in case of associated findings,
TVUS demonstrated a sensitivity of 39%,
a specificity of 56%,
a positive predictive value of 69% and a negative predictive value of 26% with a diagnostic accuracy of 43.8% (IC=23.3-62.3) (Fig.11): in this analysis the P-values were not significant in relation to the numerically limited sample.
