I HAN AN ULTRASOUND DONE ON MY NECK..  NOW THE DOC WANTS A CT SCAN.  SHOULD I BE WORRIED?

See below: Based on only the information provided it's impossible to give you specific guidance. Would need to know why the tests were done?, any symptoms? and the result of the ultrasound........But I understand your concern as it's only natural to worry about the possibility of discovering a serious condition in your body.

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

Got an ultrasound on my neck for an enlarged node I've had for 6 years. They found a 7mm mass but not sure if it was a node or not.. going for a Ct scan. If not node what else could this be?

Got an ultrasound on my neck for an enlarged node I've had for 6 years. They found a 7mm mass but not sure if it was a node or not.. going for a Ct scan. If not node what else could this be?

?Too much testing?: I do not think that a node present for 6 years is reason for imaging tests like Ultrasound and CT scans. Unless you or your doctor feel a lump on examination, there is little reason for doing such tests as their finding can be misleading and the doctors can go for a wild goose chase which carries further risks to you as a patient. Unless your node/ tumor is over one CM in size it is not of concern ...Read more

D dimer .63, negative ultrasound of leg. Please explain WHY the test is elevated with NO other reasons for elevation. Should I ask for CT scan?

D dimer .63, negative ultrasound of leg. Please explain WHY the test is elevated with NO other reasons for elevation. Should I ask for CT scan?

Unremarkable : First off there are multiple reasons for d dimer elevations other than a DVT or pe. Also- the number you quoted (63) to my knowledge is not considered to be a positive result for the test. Ct scan of the chest is a good test if you have suspicion for a pulmonary embolus or if you have a very hight risk score. If symptoms are minimal and risk is minimum then you are likely ok without a ct scan. ...Read more

Why is an ultrasound better at detecting gallstones than a ct scan?

Ultrasound said I had an loop bowel but CT scan didn't show it up,I'm in content pain please help?

Ultrasound said I had an loop bowel but CT scan didn't show it up,I'm in content pain please help?

I'm not: sure I understand the question. Did the ultrasound show a hernia that was not seen on CT? Otherwise, an ultrasound report might mention a loop of bowel that technically interferes with the scan, but is otherwise normal and wouldn't be mentioned on a CT report. ...Read more

Pain on left kidney. Ct scan shows nothing and ultrasound shows mild hydronephrosis. What would cause this?

Pain on left kidney. Ct scan shows nothing and ultrasound shows mild hydronephrosis. What would cause this?

UPJ stenosis: Ultrasound may detect early obstruction better than ct, and sometime the other way around. It depends. Anyway, left flank pain with mild hydronephrosis, and no stone is usually due to a narrowing of the joint between the ureter (pipe to the bladder) and the renal pelvis (holding area for urine). If there is a mild or partial "blockage" that could explain everything. ...Read more

Is an bladder ultrasound/ not a CT scan sufficient enough to show if you have bladder stones in your bladder?

Yes: The ultrasound can actually show non-calcified stones that may be more difficult to see on ct. Plus, there is no radiation exposure to your ovaries! ...Read more

What's the minimum size of liver and/or kidney lesions (in mm) that can be detected on CT scan and ultrasound?

What's the minimum size of liver and/or kidney lesions (in mm) that can be detected on CT scan and ultrasound?

About 10mm: About 10mm, but at that size it can depend a lot on how good the study was done. (if the operators were able to get ideal positioning for image capture), the anatomy of the patient (it's harder to get enough resolution on obese patients), and it can depend on what the lesion is - if it is solid, a simple vs complex fluid, calcified, etc. Hope this helps ...Read more

Is there a chance a bothersome hernia may go undetected with physical exam, ultrasound & CT scan? If so..what do I do?

Not likely: if ultrasound was a dedicated study done in various positions. Consult with a surgeon regarding options for treatment, such as injection or even surgical exploration, if you have continued symptoms. ...Read more

I have a 5mm stone in my left lower kidney bowl 2-11-13 had the pain and CT scan and the stone was there ultrasound 4-9 its still there ?

Probable: It is probably still there since the ultrasound shows it. Us and ct however are different in showing kidney stones. Comparing a ct to a ct study is more accurate. Your doctor or a urologist should be able to help. ...Read more

Ct scan showed upper left adnexal region cystic mass 4.2x3.2x4.2cm with thickened enhancing rim, suggested follow up ultrasound.  What does this mean?

Depends : If you are still having periods, it may just be a prominent functional follicular cyst. In a post menopausal patient it may be more concerning. I’d see a gyn and get an endovaginal us to further characterize. ...Read more

I had a CT scan about a month ago that showed a 3.5cm cyst on my spleen. Today, I went for an ultrasound to see if the cyst had changed sizes, but I was told that the ultrasound showed no cyst. Can splenic cysts disappear this quickly?

I had a CT scan about a month ago that showed a 3.5cm cyst on my spleen. Today, I went for an ultrasound to see if the cyst had changed sizes, but I was told that the ultrasound showed no cyst. Can splenic cysts disappear this quickly?

Yes: Cysts can come and go. The other aspect to consider is that u had a CT scan first which is a 3D picture with more image details initially and for follow up an US, which is reasonable to do as they should have the initial CT can results and can correlate this with the US to make sure they have the same spot. Otherwise, if they don't, then that could be the issue. ...Read more

What can a CT scan show that an ultrasound can't show?

What can a CT scan show that an ultrasound can't show?

Better details: The resolution, details shown, on ct is more effective than that of ultrasound. Ultrasound shows liquids e.g. Cysts and effusion better and is cheaper but in obese patients ultrasound has limited penetration. Accordingly, ultrasound, in these patients, is usually replaced by ct that views fatty tissues better and penetrates as deep as needed for better resolution. ...Read more

If I have CT scan and it was normal, do I need an ultrasound too?

OF WHAT? FOR WHAT?: Answer depends on what is being examined and what is being looked for. A normal ct of the chest would likely not provide information about the heart that an ultrasound could. A ct might miss some masses in the liver that an ultrasound could show and vice versa. ...Read more

Computed Tomography (Definition)

Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! the image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more

Ct Scan (Definition)

Ct scan uses data from a beam of xrays and reconstructs a cross sectional image of your body. It is a high dose of xrays and used only when the benefits outweigh the risk. Cancer risk is 1 in 500 in children. Also using iodinated contrast might cause transient renal failure in about 5% of patients. (contrast induced nepropathy) most do not explain this to the patient as ...Read more
