(A) Sagittal, panoramic, grayscale TVUS image of a cesarean scar pregnancy depicting the uterus and the area of the presumed scar from a prior cesarean birth.

(B) Enlarged and focused segment of the RMT to be measured and reported (arrow).

(C) Turning the transducer 90 degrees to obtain the transverse image of the lower uterine segment, the area of the RMT (between the two arrows) is measured and the thinnest measurement is reported.
