Evaluation and Monitoring of Endometrial Cancer Based on Magnetic Resonance Imaging Features of Deep Learning

Table 1

MRI manifestations of EC with different invasion ranges.

Invasion range	MRI appearance
Lymph nodes	Pelvic lymph node or para-aortic lymph node was greater than 10 mm in diameter
Vaginal bladder and rectum	Segmental disruption of normal signaling was replaced by that of tumor signaling
Shallow muscle layer	MRI showed partial or full-thickness disruption of junctional and subintimal enhancement bands, irregular intima-muscle interface, and no more than half of the muscle invasion
Deep muscular layer	MRI showed complete disruption of junction or subendometrial enhancement zone, tumor signal did not extend to more than 50% of the myometrium, and the myometrium infiltrated more than half of the uterus
Plasma membrane	MRI showed discontinuous outer edge of the myometrium and tumor beyond the contour of the uterus
Cervical mucosa	The internal cervical canal was widened by more than 3 mm, and the cervical fibrous stromal ring was intact
Cervical stroma	There were tumor signals in the cervical fibrous stromal ring
Limited to the endometrium	MRI showed normal or thickened endometrium (less than 5 mm after menopause and less than 10 mm before menopause), focal or diffuse abnormal signal, and intact and smooth subendometrial enhancement
