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

Exactly how many days off can a transvaginal ultrasound at 6 weeks 3 days be? I keep reading everything from two days to a full week so I'm very confused.
Depends: The error depends on which measurements are being used to date the pregnancy. If the gestational sac (the earliest sign of pregnancy on ultrasound) is all that is visible, the error can be up to a week. On the other hand, if the actual fetus can be measured (crown-rump length), the error is substantially less (approximately 3 days in the 7 week range). The error increases later in pregnancy. ...Read more

How long can a transvaginal ultrasound wand be in a vagina before it causes cavitation or heating?
See answer: As a diagnostic procedure, ultrasound is a safe and painless procedure that uses sound waves to "see" inside your body and create detailed images. The wand, aka "transducer", used for diagnostic purposes does not emit heat or cause cavitation. When used as a therapeutic or treatment procedure, such as with liposuction, more powerful transducers are used which do emit heat and can cause cavitation. ...Read more
Can a transvaginal ultrasound cause cancer from the cavitation and heating it can cause? Is it dangerous to do one 4.5 weeks after giving birth?
Can a transvaginal ultrasound and/or pelvic ultrasound show enlarged lymph nodes around the ovary?
Yes,: But not reliably. Regional bowel gas can obscure pelvic lymph nodes. Also the position of the ovaries is variable, and they may not be situated next to internal iliac nodal chains. So not seeing enlarged lymph nodes on a pelvic sonogram is not sufficient to exclude them. CT or MRI is much better. ...Read more

Thin u/s inserted: Routine female pelvic ultrasound has two portions to the exam. The exam starts with a full bladder and scanning with a fan shaped ultrasound (u/s) probe over the lower abdomen and pubic area. Then the pt is asked to empty her bladder and then a thin long u/s probe is inserted into the vagina for additional pictures. This portion is important and significantly improves parts of the evaluation. ...Read more
Different probe: Pelvic ultrasound can be performed over the lower abdomen. However, there is also a vaginal "probe" which can be inserted into the outer vagina (about an inch). It is smaller than the regular ultrasound transducer/scanner. This allows for much better imaging of the female pelvis (uterus/ovaries). It is very commonly done; it should not be painful. ...Read more

The exam starts with a full bladder and scanning with a fan shaped ultrasound (u/s) probe over the lower abdomen and pubic area. Then the pt is asked to empty her bladder and then a thin long u/s probe is inserted into the vagina for additional pictures.
