Fig. 1A —52-year-old woman with stage IB endometrial carcinoma.
Sagittal (A) and coronal (B) fast spin-echo T2-weighted images
show huge endometrial tumor that enlarges endometrial cavity. In
anteroinferior part of uterus body, junctional zone (arrow) is
thinned and not clearly visible. Myometrium is thinned to less than 50% of its
thickness. Multiple uterine fibroids are present.

Fig. 1C —52-year-old woman with stage IB endometrial carcinoma.
Paracoronal gadolinium-enhanced T1-weighted image in arterial phase shows
subendometrial enhancement line in anteroinferior part is thinned and
irregular but is continuous. These findings suggest that myometrial
infiltration is less than 50%.

Fig. 2A —56-year-old woman with stage IB endometrial carcinoma.
Sagittal fast spin-echo T2-weighted image shows endometrial cavity is occupied
by hypointense mass that causes thinning of junctional zone (arrow)
in inferior part of uterine body.

Fig. 2B —56-year-old woman with stage IB endometrial carcinoma.
Paracoronal gadolinium-enhanced T1-weighted images in arterial (B) and
late (C) phases show that subendometrial enhancement line is
irregularly enhanced but is continuous. These findings suggest superficial
invasion of myometrium.

Fig. 3A —59-year-old woman with stage IC endometrial carcinoma.
Sagittal fast spin-echo T2-weighted image shows large, lobulated, and
hypointense mass completely interrupting junctional zone (arrow) and
deeply invading myometrium. Multiple fibroids are also visible. Extent of
myometrial invasion was assessed as more than 50%.

Fig. 3B —59-year-old woman with stage IC endometrial carcinoma. Axial
gadolinium-enhanced T1-weighted MR images in arterial (B) and late
(C) phases confirm hypointense mass has invaded more than 50% of
myometrium thickness (arrowhead).

Fig. 4A —57-year-old woman with stage IC endometrial carcinoma.
Sagittal fast spin-echo T2-weighted image shows slightly hyperintense tumor
deeply invading myometrium (arrow) in inferior part of uterine body.
Junctional zone is not visible. Cervical nabothian cyst is also visible.

Fig. 4B —57-year-old woman with stage IC endometrial carcinoma.
Paracoronal gadolinium-enhanced T1-weighted image in late phase shows better
than A that transmyometrial infiltration of tumor reaches serosa in
anterior part of uterine corpus (arrowhead).
