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 to do if I did a penile duplex ultrasound and it revealed I have venous leakage, what should I do?

Venous leak: This is a common cause of erectile dysfunction. The treatment is pde-5 inhibitors (viagra, cialis, levitra) or other medical therapies. Generally surgery is not recommended. See your urologist.

I have ED and I made penile duplex ultrasound and its ok and I have obsession that I have venous leak could I have it despite the duplex is normal?

Yes: As good as ultrasound is, it is still possible that there is venous leakage. There are some direct ways to see venous drainage for a definitive answer. Talk to a urologist for more details

Cysts: They could be some kind of cystic like lesions, for example sebaceous, lipomas or fibromas which are simple and non malignant. They should cause you no harm. Good luck

Could duplex ultrasound replace arteriography in screening for mesenteric ischemia?

Could duplex ultrasound replace arteriography in screening for mesenteric ischemia?

No screening: There is nothing called screening for mesenteric stenosis. If you have no symptoms then you no need to screen for occlusion. If you have chronic symptoms then duplex ultrasound is a good starting test but has a lot of limitations. In cases of acute ischemia then ct scan is best to start with.

Carotid artery disease, different results from duplex ultrasound vs. Ct angiogram (cta), is that possible?

Carotid artery disease, different results from duplex ultrasound vs. Ct angiogram (cta), is that possible?

Results: Because these are two different imaging modalities, it is possible to get divergent results. Generally however these two studies show congruent data.

Carotid artery disease, what to believe, if different results from duplex ultrasound vs. Ct angiogram (cta)?

Carotid artery disease, what to believe, if different results from duplex ultrasound vs. Ct angiogram (cta)?

CTA better: Although cta is more accurate but it also depends on image quality done by radiology. If there is two conflicting studies of the carotid artery, then you should get the gold standard conventional arteriography if clinically indicated.

What exactly is a doppler ultrasound?

What exactly is a doppler ultrasound?

Doppler ultrasound: A doppler ultrasound uses sound waves to measure flow through vessels. When blood goes through a vessel it changes the sound waves in a way that will give us an idea if there is any obstruction or reduction in flow. This is very noninvasive and very helpful.

Why couldn't my baby heartbeat be found on a Doppler at 9 weeks and 4 days? Now I'm very scared and nervous waiting on my ultrasound appointment which is in a week.

Why couldn't my baby heartbeat be found on a Doppler at 9 weeks and 4 days? Now I'm very scared and nervous waiting on my ultrasound appointment which is in a week.

Heartbeat on doppler: In most cases, everything is ok. It may be that the lie of the fetus is so that it's hard to detect its heartbeat with a doppler machine. It's not that uncommon not to hear heart beat with a doppler machine at this gestational age. I agree things like miscarriage happen, but again in most cases, it's ok.

Is there something they will give me for anxiety when I'm doing the doppler ultrasound?

Is there something they will give me for anxiety when I'm doing the doppler ultrasound?

Not necessary: A doppler ultrasound is a painless exam. There should be no need for an anxiolytic medication. If you have a condition that will cause you to have undue anxiety for an ultrasound exam, you should discuss it with your physician so that proper measures can be taken, and medication prescribed in the rare event that it is needed.
