Can a CT scan of the neck without contrast give meaningful information on a lump? I am breastfeeding.

Can a CT scan of the neck without contrast give meaningful information on a lump?  I am breastfeeding.

Yes: It can definitely help. A ct with contrast is better. If you're worried about breast feeding with the contrast, its not an issue. The amount that is actually eventually absorbed by the baby from the stomach is extremely small. Much less than we give babies actually getting a ct scan. ...Read more

If a head & neck CT with contrast didn't show anything 6 months ago, what is the likelihood it would now? Still having pain and still no diagnosis.

If a head & neck CT with contrast didn't show anything 6 months ago, what is the likelihood it would now?  Still having pain and still no diagnosis.

Unlikely: Repeating a head CT would probably not show anything different if it was clear 6 mos ago. If the pain is severe your doctors might want to consider MRI which shows the soft tissue of the brain better than CT and gives you no radiation exposure. I hope you get some relief soon. ...Read more

Ear infx 2.5 months. Was told all kinds of infx. nothing really work. Pinching,achy feeling around ear/neck when flares up. Should i get contrast CT?

See Ear Doctor: An ear infection lasting that long should be evaluated by an ear specialist first, because you need a good exam of the ear with a microscope. This is one of the most helpful tools for figuring out what is going on in an ear. You may just need a special culture or the ear/neck pain might be something else altogether. Let an ear doctor look and decide if you need a CT... Usually don't need contrast. ...Read more

Sonogram shows 2.2cm, (2) 1cm in neck lymph's. CT contrast scan doesn't identify lymph's. I'm told its inflammation. CT does not pick up inflammation?

CT can: identify soft tissue inflammation, and can identify lymph nodes. Hard to speculate as to why the CT scan didn't show the lymph nodes, but I suspect if they looked normal the radiologist decided not to mention them. The only way to be certain is to have the radiologist look at the CT and ultrasound side by side and reconcile the discrepancy. ...Read more

Groin & cervical enlarged ln's that are visible just looking at me. Neck CT w/ contrast said they are not enlarged. Why/ how?Doc didn't get groin ct.

Need to ask your ...: Physician about these suspected enlarged lymph nodes. A ct scan of the abdomen and pelvis may be useful to further evaluate this finding depending on a physical exam.

A "hypo-dense foci in the left thyroid lobe" was found during CT w/ contrast of head and neck. What does this mean?

A "hypo-dense foci in the left thyroid lobe" was found during CT w/ contrast of head and neck.  What does this mean?

Hypo:Low; Hyper:High: Most medical terminology just descriptive, not implying any great understanding or insight. Foci means “spot”, location. Go slow, look up terms. The thyroid is a cystic gland, i.e. Cells which manufacture & secrete proteins into the water around the cells & producing accumulations of extracellular material. Lower density than surrounding tissue c/c/w cyst, just ? Larger than usual, ca ??? likely. ...Read more

Will a head and neck CT with contrast rule out a tumor? Reason I had it is constant head and neck pain on left side X6months. Normal results.

Will a head and neck CT with contrast rule out a tumor? Reason I had it is constant head and neck pain on left side X6months. Normal results.

It will rule: out a neck mass with a relatively high degree of confidence, but no test is 100%. It is likely enough to start thinking of other etiologies for your pain rather than a neck tumor, unless there is a palpable mass, in which case additional imaging may be warranted. ...Read more

Have been having pressure in right side of head behind ear for 2 months with dizziness and stiff neck on that side. Ct w/o contast?

Scan, yes: Because you are young the statistics shift toward less serious problems. However, a lesion of some type involving the mastoid or skull base near the mastoid might give you these symptoms. So, yes; you should have scan. Type of scan questionable. For bone CT is best. For other structure MR is best. Talk to your doctor. Contrast helps but we avoid in some conditions. ...Read more

I have undiagnosed mod blood and 1+  protein in my urine. I'm   supposed to get a neck CT w contrast tomorrow. Normal cmp. Should i get the ct?

Should be fine: Having normal renal function (normal cmp) makes you eligible to have a ct scan with contrast. The blood and protein in your urine do not prevent you from getting the scan, but these things need to be further evaluated by your primary care doctor. ...Read more
