This video showing the transvaginal scan and effect of increase in gains on the follicle imaging. This ultrasound of ovary showing cystic structure with internal echogenecities on left side. The right half of low gains, obscures the internal echogenecities and may misdiagnose the structure as a follicle instead of a corpus luteum; this ultrasound of ovary showing two follicles (cystic structure with no internal echogenecities) on left side. The right half of the image because of high gains, shows internal echogenecities and may misdiagnose the structure as a corpus luteum instead of follicle. Therefore in all doubtful, difficult situations, the gains are set in such a way that the urinary bladder appears anechoic and echogenicity of other structures are assessed in relation to bladder.
