XXXX in @entity1870 : assessment of @entity3 on T2-weighted spin-echo and gadolinium-enhanced T1-weighted images.

OBJECTIVE: The aim of our study was to compare T2-weighted and contrast-enhanced dynamic T1-weighted images with histologic findings in assessing the depth of @entity3 by @entity1204 in @entity1870 . MATERIALS AND METHODS: We retrospectively reviewed the MRIs of 11 @entity1 who had a total of 12 lesions of @entity1204 within @entity1870 . T2-weighted and contrast-enhanced dynamic T1-weighted images were compared with the histologic findings separately. We assessed the extent of @entity3 by @entity1204 . The depth of @entity3 seen on MRI was classified as stage S (superficial invasion), stage D (deep invasion), or undetectable. The @entity5 accuracies of each sequence were assessed. The @entity5 -myometrium contrast-to-noise ratios were calculated for each sequence. RESULTS: The histologic specimens revealed that @entity3 was deep in seven of 12 lesions and superficial in five. On T2-weighted images the depth of invasion was underestimated in two lesions and impossible to determine in five lesions. On dynamic T1-weighted images the depth of invasion was overestimated in one lesion and underestimated in one lesion. The @entity5 accuracy on dynamic T1-weighted images (83%) was significantly higher than that on T2-weighted images (42%). The contrast-to-noise ratio was significantly higher on dynamic T1-weighted studies during the early phase (mean +/- SD, 2.68 +/- 0.94) than it was on T2-weighted studies (1.74 +/- 1.05) and during the delayed phase (2.01 +/- 0.86). CONCLUSION: When @entity1870 coexists with @entity1204 at the same site on T2-weighted images, contrast-enhanced dynamic T1-weighted imaging improves the accuracy of @entity5 .
