These ten images can help ob/gyns recognize the additional information GBCA administration provides in MRIs.
Endometrial CA Cor T2
Coronal T2 with endometrial mass extending into right cornua (yellow arrow) and effacing the junctional zone. Normal endometrium with very bright T2 signal (green arrow).

Endometrial CA diffusion
Axial diffusion b value 800 s/mm2 shows endometrial lesion with high signal (yellow arrow).

Endometrial CA ADC
ADC map with low signal (yellow arrow) consistent with water restricting lesion associated with neoplasm.
Endometrial CA early post contrast VIBE
Hyperenhancement of uterus and endometrial cancer in uterine cavity (arrow).
Endometrial CA late post contrast VIBE
Late post contrast VIBE image better depicts the myometrial invasion at the anterior and fundal aspect of uterus (yellow arrow) with wash out of the contrast in mass compared to the enhancement of the normal uterine body.
Fibroid Sag T2
Sagittal T2 Haste showing large ventral fibroid (yellow arrows) with characteristic low signal in swirling configuration. Fibroid abuts the low signal junctional zone surrounding the bright endometrium (red arrow).
Endometrioma Sag T2
Zonal anatomy of uterus is well depicted on sagittal T2 Haste image with central bright endometrium, low signal junctional zone and heterogeneous bright secretory phase myometrium. Posterior to uterus is the ovary containing a well defined intermediate signal lesion (arrow).
Endometrioma Ax T1
Axial T1 shows several multiple high signal well circumscribed masses in both adnexa, the largest corresponding to intermediate T2 lesion on sagittal view consistent with endometriomas.
