Warren Janowitz MD's Expert Contributions
Do radiologists do ultrasounds?
Yes, most do. Cardiac US usually done by cardiologists. READ MORE
Can CT scans cause thyroid problems?
The amount of radiation is minimal and unlikely to cause any damage. Iodide in contrast could conceivably cause short term issues, but unlikely. READ MORE
Is a CT scan without contrast effective?
Depends on what the CT is for. Some need contrast or will not be diagnostic. READ MORE
Risk of cancer from CTs?
There is a slight risk of cancer from CTs. There is usually a delay of about 10 years before a cancer develops. Most doctors think the benefits outweigh the risks. I would recommend that you ask your doctors if there is an alternative such as US or MR. If not I would have the CT if it is necessary. READ MORE
Does a neck CT scan show your thyroid?
Yes. READ MORE
Ultrasound vs CT scan with contrast?
Depends on who is interpreting each study. READ MORE
Covid and radiology (mammogram)?
No restriction before booster. May be enlarged lymph nodes for some time after booster. READ MORE
What is the best imaging for kidney stones?
Non-contrast CT is probably most sensitive. Downside is radiation. Ultrasound has no radiation and will detect most stones. READ MORE
How long after radiation can you be around a pregnant woman?
Unless you are getting injected with or orally taking a radioactive drug there is no need to avoid pregnant women. If you are, you need to check with the physician administrating the drug to find out. Also some radiotherapy procedures involve radioactive implants and also need to to be discussed with your doctor. READ MORE
Is radiation from the sun dangerous?
Yes. It causes skin cancer. READ MORE
How long are you radioactive after a PET scan?
Half-life of F-18 is about 2 hours. 8 half-lives, or 16 hours would leave only a minimal amount of radiation. READ MORE
What happens if you eat sugar before a PET scan?
If your sugar in the blood is too high the PET will be rescheduled since the drug injected s a form of sugar and the scan will not be accurate. READ MORE
Is there radiation in a PET scan?
Yes. There is radiation from the drug injected and from the CT scan that is used with the PET in most cases. The radiation is low risk for future problems, and the benefit outweighs the risk, especially if it is being done for cancer. READ MORE
Where do you stand during fluoroscopy?
Mostly done remotely. Sometimes need to be in room next to patient. READ MORE
Does fluoroscopy require contrast?
Oral contrast if it’s for the GI tract (stomach, bowel). Some kidney studies may need contrast. READ MORE
Can an x-ray show brain swelling?
No. Need CT or MR. READ MORE
Do you lose your hair with radioactive iodine treatment?
No READ MORE
Can you get an MRI or CT scan while pregnant?
MRI is OK. CT can be done if necessary if pelvis is shielded, better after 1 st trimester. If pelvis is scanned risk is low, but not zero. Should discuss risks with radiologist. READ MORE
How much radiation is in an ultrasound?
There is no radiation in ultrasound. READ MORE
Can a CT scan affect early pregnancy?
Prefer not to do a CT in early pregnancy unless there is a medical necessity. Head and neck and chest CTs would have minimal exposure to the pelvis which can be shielded. Abdominal and pelvic CTs would have a higher risk. Risk to fetus is minimal but not zero in the first trimester. An MRI or ultrasound could be a substitute, but not always. If there is a significant medical problem the CT may need to be done. You would probably need to sign a consent if pregnant and could talk to the radiologist about possible risks. READ MORE
