Sensitivity varies between 42% for lesions <1 cm and 95% for tumors larger than 1 cm, and specificity can reach 90%. Optimal time interval for ultrasound screening of “at risk” population is 6 months as it results from clinical trials that investigated the tumor size doubling time (Bruix, 2005; Maruyama et al., 2008).
A United States practice is to perform liver ultrasound at 6 months and 12 months after the initial diagnosis, and if the size has not increased, further follow-up is not necessary. [6] Particular situations that may indicate imaging are: [6] New onset abdominal pain; Initiation of estrogen therapy; Pregnancy

Obstetric ultrasonography, or prenatal ultrasound, is the use of medical ultrasonography in pregnancy, in which sound waves are used to create real-time visual images of the developing embryo or fetus in the uterus (womb). The procedure is a standard part of prenatal care in many countries, as it can provide a variety of information about the ...
Nuchal translucency. Purpose. Used to screen for abnormalities in a developing fetus. A nuchal scan or nuchal translucency ( NT) scan / procedure is a sonographic prenatal screening scan ( ultrasound) to detect chromosomal abnormalities in a fetus, though altered extracellular matrix composition and limited lymphatic drainage can also be detected.
Amniotic fluid index ( AFI) is a quantitative estimate of amniotic fluid [ 1] and an indicator of fetal well-being. It is a separate measurement from the biophysical profile. [ 1] AFI is the score (expressed in centimetres) given to the amount of amniotic fluid seen on ultrasonography of a pregnant uterus. To determine the AFI, doctors may use ...
Anomaly scan. The anomaly scan, also sometimes called the anatomy scan, 20-week ultrasound, or level 2 ultrasound, evaluates anatomic structures of the fetus, placenta, and maternal pelvic organs. This scan is an important and common component of routine prenatal care. [ 1] The function of the ultrasound is to measure the fetus so that growth ...
