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

Would 3 ultrasounds of the leg miss a dvt?

Would 3 ultrasounds of the leg miss a dvt?

DVT: It woulld be very unusual for 3 us to miss dvt. Venous us is quite sensitive and specific for diagnosis of both DVT and superficial thrombosis. Why do you need to repeat three us of leg. Do you have any symtoms such as leg swelling/pain? Hopely radiologist agrees with me. I haven't seen any.

2 d-dimers & ultrasounds in 1 week both say negative for dvt. But still have pain and worried I have DVT and they missed it. Should I worry?

2 d-dimers & ultrasounds in 1 week both say negative for dvt. But still have pain and worried I have DVT and they missed it. Should I worry?

Very Very Unlikely: You have had two ultrasound exams and 2 d dimers and oth negative. I think DVT has been ruled out not ince but twicethere may be some other cause of your leg pain.Discuss with your doctor and follow with his/her advice dvt will not be missed on two tests. It is highly likely that your leg pain is from dvt.

Could an ultrasound scan miss a DVT as iam at high risk of a DVT and is 422 high for a d dimer test?

Could an ultrasound scan miss a DVT as iam at high risk of a DVT and is 422 high for a d dimer test?

Ultrasound for DVT: Ultrasound for lower extremity DVT's have great sensitivity and specificity meaning they are very good at picking up a DVT. There is a 2% chance of somebody having a negative scan and having one found 1 week later according to studies, although repeating it is often done if there is strong suspicion. D-dimer values are not universal so that may be high but values can be high in a lot of disease.

What to do if I have a possible dvt, have had an ultrasound, it did not show, has anyone experienced this?

What to do if I have a possible dvt, have had an ultrasound, it did not show, has anyone experienced this?

Ultrasound can miss: A venous doppler ultrasound is good test for finding a dvt. However it is possible that it can miss a small or incomplete dvt. This is not an uncommon event so if you still have symptoms and think it might have missed a DVT follow up with you doctor to discuss options such a repeat test or other tests.

Please tell me, could a free clinic do an DVT ultrasound?

Not in the clinic: Most free clinics are not capable of doing a DVT ultrasound but they can refer you to a diagnostic facility or an hospital out patient department whwre it can be done and may be done under charity care if you qualify for charity care. Discuss the options with the doctors at the free clinic as they have the knowledge where it can be done only if it is medically indicated.

Should a known dvt in the leg be monitored with regular ultrasounds to ensure dvt has not moved or got bigger or no new dvt's have developed?

Should a known dvt in the leg be monitored with regular ultrasounds to ensure dvt has not moved or got bigger or no new dvt's have developed?

Not useful: The DVT can take up to 6 months to dissolve completely on blood thinners (Coumadin or 1 of the newer agents) for the time period specified by your doctor. While ultrasound is useful in detecting a DVT (due to Doppler), it is less useful in showing how big/small the clot is over time. Your best bet is warfarin: that has shown to prevent migration of even small flecks of the clot. Se HealthTap Prime

My leg been hurting for 3 weeks from my calf up. .... 2 ultrasounds came back negative for dvt. I'm worried are these test pretty accurate? Help

My leg been hurting for 3 weeks from my calf up. .... 2 ultrasounds came back negative for dvt. I'm worried are these test pretty accurate? Help

They are: They are highly accurate for detecting a blood clot in the leg, 97% accurate by most studies which is excellent. There are many causes of leg pain, and in fact, a clot typically won't cause pain unless the vessel becomes inflamed. A clot in the leg most often manifests as new significant swelling of one leg relative to the other, often after a period of immobilization such as a long flight.

Pinch feeling in same spot of inner thigh. I've had ultrasounds but still scared of dvt. What could this be.

Pinch feeling in same spot of inner thigh. I've had ultrasounds but still scared of dvt. What could this be.

Doubt dvt: What you have described is unlikely a dvt. The "inner thigh" is a big region but in my view any leg pain should lead ones doc to rule out a 'pinched' or irritated nerve. You did not mention back pain but we have all seen nerve root compression with little or no back symptoms. This said, you are very young to have this as a problem but I would still rtulle it out.

What can cause deep calf pain?, I've had it for a month and its been getting worse. I had an ultrasound 2days ago to rule out DVT that was clear.

What can cause deep calf pain?, I've had it for a month and its been getting worse. I had an ultrasound 2days ago to rule out DVT that was clear.

Calf pain: Many things can cause calf pain aside from a blood clot. Venous insufficiency, arterial disease, lymph-edema, sprains, strains to name a few. I would recommend evaluation by your primary care physician

Is it true that using ultrasound below the knee to check for DVT isn't very accurate?

Is it true that using ultrasound below the knee to check for DVT isn't very accurate?

It's true it's limit: The gold standard for DVT diagnosis is an IVP but are rarely necessary. A clinically significant DVT but the technician can miss it of course. Evaluate all the information you have to decide if thrombus is present or not

2 ultrasounds in a week 3 ddimers of 307. Dr says no dvt. I still have leg pain after 2 weeks. What are chances it's still a clot? Worried.

Needs further eval.: D-dimer is a very non specific blood test. A negative d-dimer and a negative venous ultrasound rule out DVT. Your leg pain does not seem to go along with a DVT especially with 2 normal ultrasounds. Since the d-dimer can be elevated for many reasons, a ct of the iliac and proximal femoral veins would complete your evaluation and definitively make or rule out the diagnosis.

I had a ultrasound of the leg cause we had a scare that it could be a dvt. But they found a poppliteal lymph node that is painful. Should I worry?

I had a ultrasound of the leg cause we had a scare that it could be a dvt. But they found a poppliteal lymph node that is painful. Should I worry?

Do not worry: An ultrasound is the gold standard for evaluation of a clot from the groin to below the knee. Since it did not show dvt, you do not have any clots which would have been a worry. A popliteal lymph could very well be a normal finding and could also be the result of any inflammation in your leg. Follow up with your md.

4 yrs. Ago had leg pain, ultrasound performed and told no DVT. Now seeing report says lesser saphenous occluded, should I be worried,? no one told me!

4 yrs. Ago had leg pain, ultrasound performed and told no DVT. Now seeing report says lesser saphenous occluded, should I be worried,? no one told me!

Not a lot: The saphenous is a superficial vein, and not DVT. However, any clot is abnormal and you should be evaluated for platelet function, clotting issues, varicose veins. The cause of your superficial venous thrombus may still be important in your life! While no DVT we generally would tell someone about any abnormality. It may also have been very chronic and scarred at the time.

Do I have DVT if my leg hurts I have no swelling but constant pain, I had an ultrasound and it was negative but I have since then taken another flight?

Possibly: I would recommend another ultrasound to rule out a dvt, especially if the pain is worse. If its negative, look into other causes for your leg pain.

Got ultrasound on leg-groin for leg pain suspecting dvt found nothing but would like second ultrasound for assurance how do I get second without refer?

Got ultrasound on leg-groin for leg pain suspecting dvt found nothing but would like second ultrasound for assurance how do I get second without refer?

You will need a: Physician's order to obtain a repeat and if you are insured it is unlikely that the second one will be paid for. In other words you will have a big bill to pay. It is not reasonable to obtain a second study as the likelihood of it being any different is extremely small. Talk to your health care provider about your concerns.
