Sonogram (Definition)

An ultraound, also known as a sonogram, is a painless and relatively inexpensive imaging test that utilizes sound waves instead of ionizing radiation. There are no side effects. Ultrasound can give us two-dimensional, and in some applications three-dimensional, images of structures and organs in virtually any part of the body. In addition to diagnostic uses, such as evaluating abnormalities in the abdomen, pelvis, and breast, ultrasounds are commonly used to guide needle and catheter placement in a variety of surgical ...Read more

What does it mean if the ultrasound did not see anything in the sac?

What does it mean if the ultrasound did not see anything in the sac?

Blighted ovum.: That would depend on how advanced the pregnancy is. By 5 weeks there should be at least a yolk sac present in the gestational sac in the uterus. By six weeks a fetal pole should be seen and 85 to 90% of the time a fetal heart beat is noted by six weeks. If there is no fetal pole or yolk sac present by six weeks, it is unlikely that the pregnancy is normal. That is referred to as a blighted ovum. ...Read more

For example, if it was weight, it would mean that the baby weighs more than 75% of all babies the same age. ...Read more

Had first ultrasound with p70, 8c5, 7.5, 32fps, dr60, 2dg, 80 numbers on it. What does these mean??

Likely not relevant.: Difficult to answer without looking at the actual image where these numbers appear. I can guess a few: "8c5" is the name of the transducer manufactured by Philips; "7.5" likely also refers to transducer frequency; "32fps" = 32 frames per second. Others, I have no clue. ...Read more

What does a black mass from ultrasound mean?

"Black mass": Does not provide any information with regard to the possibilities. In ultrasound we don't use the word "black". We use different language such as solid, hypoechoic, etc. To describe masses and possibilities depend on the specific ultrasound appearance, organ being studied, patient history, lab tests, and whether or not there is vascular flow associated with the mass. ...Read more

What does the blue and red in the ultrasound mean?

Blood Flow, Motion: Doppler detects movement, typically of the blood. Red usually means flow towards transducer, blue away but they can be reversed. Movement of the heart and the cardiac valves can also generate color signals. Jets of urine entering the bladder or amniotic fluid in and out of the fetal nose will also show color. ...Read more
