Elevated D dimer. Negative PE CT scan and venous extremity ultrasound. D dimer never elevated before but is now 3 x. I’m only 23. Concerning??

Elevated D dimer. Negative PE CT scan and venous extremity ultrasound. D dimer never elevated before but is now 3 x. I’m only 23. Concerning??

Little concern: Perspective: D dimer tests well known to be nonspecific. A common cause of high D dimer is clot somewhere in the body. So when there's suspicion of clot, D dimer test can be useful. If D-dimer low, usually means no clots. If elevated, doesn't mean there is clot because many things like liver disease, high rheumatoid factor, inflammation, recent surgery, others cause high D-Dimer. Hope this helps. ...Read more

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

Tsh @ 6.85, ft4 normal ultrasound: normal size, extremity heterogeneous, normal vascularity but irregular heterogeneous nodule 1.1x0.7x0.7cm. Cancer?

Tsh @ 6.85, ft4 normal  ultrasound: normal size, extremity heterogeneous, normal vascularity but irregular heterogeneous nodule 1.1x0.7x0.7cm. Cancer?

Not Likely: Thyroid nodules are very common. About 70% of the population has a nodule (many don't know it). About 5% of nodules are cancerous, which is why we care. If there were concerning characteristics on the ultrasound like microcalcifications, taller than wide, >1cm or increased blood flow or you have a family history or radiation exposure we like to perform an fna biopsy to check for cancer. ...Read more

How can I have a ultrasound in the lower extremity that revealed venous insufficiency in the saphenous vein but no varicose vein?

How can I have a ultrasound in the lower extremity that revealed venous insufficiency in the saphenous vein but no varicose vein?

Veins are deep: The saphenous veins in the legs may lie very close to the skin, or a little deeper, covered by fat. If deeper saphenous veins have insufficiency, the varicosities may not be visible because they are the deeper kind. ...Read more

Doc thought I had a dvt in my leg post op. ER did ultrasound and found biphasic flow in lower extremity and said pvd. I am 27yo. Is this likely?

Doc thought I had a dvt in my leg post op. ER did ultrasound and found biphasic flow in lower extremity and said pvd. I am 27yo. Is this likely?

Usually a: venous doppler ultrasound is performed to evaluate for DVT(maybe you had it done as well), but you are describing findings of an arterial doppler. Biphasic flow is abnormal and suggests PVD, as you describe. It would be every unusual for a 27 yo to have significant atherosclerotic changes unless you are diabetic or have another predisposing disorder, so you need to talk to your doc about results ...Read more

Can a fetus with IUGR or any disorder measure at 6 weeks on an ultrasound, but in reality is 23 weeks gestation? How far behind can iugr babies be? Plus if a baby is iugr does it still develop limbs at the accurate week? Thanks

Can a fetus with IUGR or any disorder measure at 6 weeks on an ultrasound, but in reality is 23 weeks gestation? How far behind can iugr babies be? Plus if a baby is iugr does it still develop limbs at the accurate week? Thanks

Doubt it: I suppose there are some birth defects like primordial dwarfism that may have such an pattern but not a normal infant. IUGR babies are small but develop arms/legs at the same time. The 6 wk fetus has flipper like arms/legs that are distinctive while those past 8 wks have recognizable digits & 12 wks are well formed. ...Read more

Doctors say iugr fetus’ are “small” for their age in utero, does this mean that the fetus is just a small version of healthy fetus same age? Or can this mean limbs etc. aren’t seen yet on ultrasound and the fetus is delayed by anatomy wise too

Doctors say iugr fetus’ are “small” for their age in utero, does this mean that the fetus is just a small version of healthy fetus same age? Or  can this mean limbs etc. aren’t seen yet on ultrasound and the fetus is delayed by  anatomy wise too

Small means small: Essentially all fetuses have all external parts formed by 12 wks, The Small for dates label is applied to those who are not putting on weight/size as expected for the stage of pregnancy. There are various potential causes from a poor placental attachment, maternal high blood pressure, metabolic issues,infection & many others. ...Read more

How many ultrasounds should I get?

How many ultrasounds should I get?

Varies: Some pregnancies require no ultrasounds. Most doctors will order at least one preferably done between 18-22 weeks when we can evaluate the anatomy of the baby. An ultrasound can be done in the late first trimester as part of genetic screening. Other sonograms would be ordered for a variety of medical conditions and complications of pregnancy. ...Read more

How accurate are early ultrasounds?

How accurate are early ultrasounds?

The most accurate: The earlier you get your first ultrasound, the more accurate is the estimate of your due date and the age of the pregnancy. During the first trimester, the dates are within about a week of the actual conception date. Later in the second trimester, you can be at least 2 weeks off. If you were to present for your first sono in the third trimester there can be 3 or more weeks of uncertainty of dates. ...Read more

How accurate are 32 week ultrasounds?

Depends: On what ?S are being asked. Best time to date the age of the fetus is 8-13 weeks. Best time to evaluate the anatomy is 18-22 weeks. As they get older, there is less accuracy, since all fetuses (like their parents) are different. Older fetuses are bigger, so it can be easier to see somethings, but it is more likely some part of the fetus will be in the way of what you are trying to look at. ...Read more

Are testicular ultrasounds accurate?

Are testicular ultrasounds accurate?

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. ...Read more

What is an ultrasound used to diagnose?

Many Disease: An ultrasound exam is indicated in the following: lesion vs. Cyst formation in organs. Stone formation in specific organs/systems. Palque or blood clot blockage in vessels. Fetal viability, position, size, gestations and possible anatomical abnormalities. Organ size and location. This is only a general list of what a basic ultrasound machine can do. There are more advanced ones that can do more. ...Read more

How actuate are the ultrasound measurements?

Depends on what it i: The accuracy & precision of an ultrasound machine depends on many factors, including the freq of the ultrasound transducer (higher frequency = better resolution), but also the structure imaged: the deeper the object, the lower the frequency used, to get penetration. Also, the tech/user technique comes into play: did they get the angle right? How hard do they press? Doppler flow is similarly variab ...Read more
