Gynecologic ultrasonography or gynecologic sonography refers to the application of medical ultrasonography to the female pelvic organs (specifically the uterus, the ovaries, and the fallopian tubes) as well as the bladder, the adnexa, and the recto-uterine pouch. The procedure may lead to other medically relevant findings in the pelvis.This ...
Poon was the first researcher to have developed an effective first trimester prediction model based on a combination of maternal factors, blood pressure, uterine artery Doppler, serum pregnancy-associated plasma protein-A and placental growth factor for early-onset preeclampsia, achieving a detection rate of 90%, at 5% false-positive rate.
Uterine artery can arise from the first branch of inferior gluteal artery. It can also arise as the 2nd or 3rd branch from the inferior gluteal artery. On the other hand, uterine artery can be first branch from internal iliac artery before the superior and inferior gluteal arteries branching off from the main arterial trunk.
The pelvic exam during pregnancy is similar to the exam for non-pregnant women; however, more attention is given to the uterus and cervix. The size of the uterus is assessed at the initial visit, and the growth of the uterus is assessed at subsequent visits. In the first trimester the uterine size can be assessed on bimanual examination.
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
Applying spectral Doppler to the renal artery and selected interlobular arteries, peak systolic velocities, resistive index, and acceleration curves can be estimated (Figure 4) (e.g., peak systolic velocity of the renal artery above 180 cm/s is a predictor of renal artery stenosis of more than 60%, and a resistive index, which is a calculated ...

The power Doppler or Doppler ultrasonography function can be used during transvaginal ultrasonography to help differentiate adenomyomas from uterine fibroids. [ 24 ] [ 28 ] [ 29 ] This is because uterine fibroids typically have blood vessels circling the fibroid's capsule.
