What radiology scans have white backgrounds and which ones have black backgrounds?

What radiology scans have white backgrounds and which ones have black backgrounds?

Can be either way: Historically most studies are read with a black background due to the nature of film developing process. However most images are digital and black on white and white on black can be changed with a click of the mouse. Most radiologists prefer white on black, with the exception of live fluoroscopy ...Read more

How long is the ideal time between one pet scan and another?

Depends disease/time: Pet scan may be obtained for different purpose: staging disease, assessing treatment response or surveillance. Prior to assess tumor response your physician may want you to receive variable x number of treatments.

Can one do whole body scan to check any kind of cancer?

Can  one  do  whole  body  scan  to  check  any  kind  of  cancer?

Resolution of scan.: It depends on which scan we are talking. In general the resolution i.e the ability of a "scan" depends on the nature of the test.
For a CT scan to detect an abnormal finding the lesion has to be greater than a cm, MRI can give an abnormal signal, a PET CT may be more sensitive.
Blood tests measuring DNA or circulating cancer cells may be a more sensitive but it may not reveal the location. ...Read more

I want to have an upcoming PET scan compared to the one 3 months earlier. Do I request a comparative report or a comparative study? What exactly?

I want to have an upcoming PET scan compared to the one 3 months earlier. Do I request a comparative report or a comparative study? What exactly?

I don't: know any facility that would perform a PET scan without a physician's order, so you probably don't need to worry about how to word the request. If you already have the order and want to make sure the facility has the proper information, when you call to schedule the test, tell them that you had a prior PET scan(when and where) and that this is a follow up study. ...Read more

One enlarged testesi have had a scan but nothing was found , only fluid?

Testicles: In general one of your testicles will always be bigger than the other one. One is more dominant. As men age they often have scarring in the tubing or the testicle that can collect fluids and ache at times. Without any more information from you that is all i can comment on now. It sounds like you are normal to me. ...Read more

Have been diagnosed with pof and had a scan showing one follicle on ovary, what does this mean?

Have been diagnosed with pof and had a scan showing one follicle on ovary, what does this mean?

Follicle = egg: Often the term follicle is used synonymously with egg. They are technically not the same but it just means they saw what looked like a follicle/egg in your ovary. Pof as you know results in low estrogen and high follicle stimulating hormone fsh. Fsh usually has a quick spike right in the middle of the menstrual cycle and this usually causes the ovary to release an egg. ...Read more

If i had rai uptake scan done 6 months ago, should I have another one done if my symptoms still persist?

Depends: Usually radioiodine uptake and scan are performed for hyperthyroidism or hypothyroidism. Medications are usually prescribed for these diseaes. Radioiodine therapy is sometimes used for hyperthyroidism. Unless your physician feels because of therapy issues or change in symptoms, the test is not usually repeated on regular basis. If following thyroid cancer, that scan is done for surveillance. ...Read more

my dating scan 1st August 2014 dated me 12w 5days who is the dad?  the one on the 20th april or  the second on the 29th april til middle of may?

Second one: Thirteen weeks is a trimester, or 91 days, which puts your date if conception around the 3rd of May. Since there is an error factor of +/- 5d - 2weeks, you will probably need to do paternity testing, since within this error factor, either one could be the dad, within the error if the testing technique. Dad #2 is the front runner in this calculation, but can't rule out #1 by dates alone ...Read more

One month post medical abortion TVS scan shows endometrial thickness of 3 MM and no RPOC. and Two months post abortion the endometriom shows RPOC.

One month post medical abortion TVS scan shows endometrial thickness of 3 MM and no RPOC. and Two months post abortion the endometriom shows RPOC.

Unclear: You did not ask a question so it is unclear what you are asking. If abnormal endometrial tissue is noted on a transvaginal sonogram then it should be investigated by hysteroscopy, D and C or at least an endometrial biopsy. Retained products of conception are certainly one possibility but that diagnosis can not be made exclusively by sonogram ...Read more

Can I take something for Diarrhea before a HIDA scan? I'm having one tomorrow but I stay sick even though I barely eat. Would meds to stop it be OK?

Can I take something for Diarrhea before a HIDA scan? I'm having one tomorrow but I stay sick even though I barely eat. Would meds to stop it be OK?

Some meds avoided: Do not take any pain medications prior to test. Pain medications interfere with scan. Peptobismol should not be take because contains metal that can interfere with results. Barium studies should not be performed within several days of HIDA study. ...Read more

Dr. just ordered a bone scan to find out the density I guess never had one before can you please tell me how this test is done or all about it and why?

Bone Density: I'm assuming you mean a DEXA scan for bone density? It is a quick, simple, painless test. It is essentially equivalent to getting an X-ray. You lay on the scan table, the tech takes the scan, and you are done. No preparation necessary. ...Read more

I find a lot of conflicting evidence on the average radiation dose from a CTPA scan. I had one back in 2012 and was curious as to an estimatd rad dose?

I find a lot of conflicting evidence on the average radiation dose from a CTPA scan. I had one back in 2012 and was curious as to an estimatd rad dose?

You are wise to be: aware of your radiation dose, but don't let it scare you too much. Seek to keep your exposure low, but don't refuse a study which is medically necessary. Most imaging centers keep track of the radiation dose you received. Call and ask them for your radiation dose on file. If you have the CT on a CD, I can review it at HealthTap Concierge healthtap.com/saurbornmd. It might have dose information. ...Read more

My scan looks just like the one below. Is that bone mets?

Not your call: There are some ringers for metastatic disease. Don't self-diagnose based on something you saw on the internet. If you are having a scan done, I understand how difficult this time must be and you have my sympathy. But the report by the radiologist should be available by the time you get this. ...Read more

21 weeks preg. Had my scan yday and found the bub is 320 grams. Is it a good weight? One of the kidneys diallating showed 4.2 mm. Is something wrong?

36%tile; pyelectasis: The estimated fetal weight is at the 36%tile for 21 weeks (i.e. Normal). The fluid in the fetal kidneys is at the maximum normal (4 mm) at this stage and merits follow-up ultrasound at 32 weeks to make sure it is not getting worse. You should be content that things are going well and keep all prenatal care appointments. Best of luck! ...Read more

Is it possible for a scan to reveal only one baby when there are twins?

Is it possible for a scan to reveal only one baby when there are twins?

Yes: In general an experienced sonographer can detect two sacs or two fetuses in the first trimester and beyond. Sometimes one twin will be missed if it is not developing normally (eg, stuck twin) or is in one corner (horn) of an abnormally shaped uterus or if the woman is very large. Those would be very rare exceptions at most centers today. ...Read more
