Question 1

are testicular ultrasounds accurate?

Accepted Answer

Generally, yes.: Scrotal ultrasounds (us) are very sensitive for determining the presence of testicular masses, cysts, and relatively sensitive for detecting infection. Doppler studies done by us are very good at determining blood flow and evaluating torsion. Though us can make a diagnosis of tumor, it usually cannot reliably predict the type of cancer. The experience of the technician also makes a difference.

Question 2

are 11week ultrasounds accurate for dating? margin of error?

Accepted Answer

Varies: The range of error for an ultrasound at that point would likely be around +/- 8 days.

Question 3

can a 10 week ultrasound be off by 2 weeks(+/-2 weeks) or is a 10 week ultrasound accurate?

Accepted Answer

Accurate: Shouldn't be off by more than a couple of days.

Question 4

are baby gender ultrasounds accurate? is there any chance that an ultrasound showing my baby's gender is wrong? i'd hate to completely prepare for a b?

Accepted Answer

Nothing is 100%!: Fetal ultrasounds are generally accurate when predicting a baby's gender but there are times when it is not correct.  Best to be surprised anyway!

Question 5

are ultrasounds accurate at dating conception at 12 weeks?

Accepted Answer

Not as accurrate: As they are at 4-6 weeks.

Question 6

is a 8wks ultrasound accurate? it was suppose to be 10wks due date 7/13/15 but after u/s . it was 8 wks..and when did i conceive due date?? 07/27/2015

Accepted Answer

Highly accurate: First trimester US based on CRL is accurate to +/- 2-3 days if done correctly. Your assumed 10 weeks/ EDD 7/13/15 is almost certainly incorrect. Conception is likely around November 3 2014, but this is just a calculated guess. Good wishes.

Question 7

is week 11 transvaginal gender ultrasound accurate?

Accepted Answer

Not likely: Gender body parts can be reliably seen starting at 19-20 weeks.

Question 8

is an ultrasound accurate to diagnose temporal arteritis?

Accepted Answer

: No,clinical suspicion and a temporal artery biopsy are needed in order to formulate a definitive diagnosis.

Question 9

is a dating ultrasound accurate showing 8 weeks if the fetus has iugr and woman has no known lmp? can the fetus actually be 20 weeks along and just look like 8 weeks due to iugr

Accepted Answer

Quite accurate dates: 20 weeks never looks like 8 weeks, just like a 20 year-old who was malnourished and neglected all his life will still not look anything like a normal 8 year-old boy. In a natural pregnancy, ultrasound dating that shows an 8 week fetus is an estimate that the pregnancy is 7-9 weeks. Avoid overthinking this, unless it is 100% impossible that there was a sperm meeting an egg 5-7 weeks ago.

Question 10

is an abdominal ultrasound accurate at 6w4d? could it pick up my heartbeat instead of the baby's? the tech told me the heartbeat was 100 but later the doctor said it was 70? so confused. please help?

Accepted Answer

: The fetal heart (and heartbeat) can usually be detected at a gestational age of 6w4d.  Fetal heart rates are usually higher than 100 and certainly 70, so this may be a maternal reading.  For assessment of fetal growth, repeat the U/S in a couple weeks, and/or obtain a quantitative HCG determination to help ensure normal progress of fetal growth.
