An intradecidual sign depicts transvaginal sagittal grayscale ultrasound imaging in a 34-year-old pregnant patient, which shows a 4-mm empty gestational sac (solid arrow) in the anterior endometrium. The location of the sac to one side of the central hyperechoic line (dotted arrows) representing the opposed innermost layers of decidualized endometrium confirms it is within the endometrium and not the endometrial cavity, hence the name intradecidual sign. This sign is helpful when seen to diagnose a probable intrauterine pregnancy before visualization of the yolk sac. Three days later, the yolk sac was visualized (not shown), allowing for the diagnosis of a definite intrauterine pregnancy.

Sample images show cancer detection at supplemental ultrasound screening after screening mammography with a negative result. (A) Craniocaudal right breast screening mammography shows negative findings in a 54-year-old female patient with extremely dense breast tissue. (B) Coronal view from supplemental screening with automated whole-breast ultrasound image in the same patient four months later shows an irregular hypoechoic mass (dashed yellow circle) in the right breast, diagnosed as invasive ductal carcinoma. (C) Craniocaudal screening right breast mammography shows negative findings in a 74-year-old patient with heterogeneously dense breast tissue. (D) Antiradial gray-scale image in the right breast from supplemental handheld screening ultrasound in the same 74-year-old patient 7 months later demonstrates an irregular hypoechoic mass in the right breast (yellow outline), which yielded a diagnosis of invasive ductal carcinoma.
