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

Mnday i had a routine mammogram and a CT scan on my back; thursday routine xrays at dentist. Is this too much radiation? I am a 46 yr old african am. Woman in good health on no medications.

Probably just fine: We all want the least cumulative x-ray exposure always. However, the ability to provide an accurate assessment and diagnosis often requires these studies. Because the area of exposure with the dentals is dictant from the rest, there is no need for worry. About them. If your dentist has digital x-rays, the exposure is decreased by 60 - 70 %. You might want to spread out the other 2 if possible. ...Read more

What to do with conflicting CT scan results? I had a mammogram and a CT scan done. The CT scan showed a lump in my breast but the mammogram didn't show anything. What is done in situations like these? Should another test be done other than CT or mamogra

What to do with conflicting CT scan results? I had a mammogram and a CT scan done.  The CT scan showed a lump in my breast but the mammogram didn't show anything.  What is done in situations like these? Should another test be done other than CT or mamogra

Dedicated : Dedicated ct imaging of the breast is essentially only performed in a few research facilities, so i will assume that something was found in your breast incidentally during a ct of your chest. First, make sure that the radiologist performing the mammogram had the ct scan for comparison. If you feel the lump that was seen on ct, then you should probably have an ultrasound performed in the area for further evaluation. If you do not feel the lump and the radiologist compared the mammogram with the ct and was not concerned, then the ct finding was probably incidental and no further evaluation would be indicated. However, if you are still concerned you could have a follow-up mammogram in six months to ease your concern. ...Read more

If a CT scan shows a breast lump and the mammogram does not should another test be performed?

If a CT scan shows a breast lump and the mammogram does not should another test be performed?

Maybe: If the radiologist looks at both studies and determines that a normal structure on the mammogram accounts for what looks like an abnormality on CT, then no. If the mammogram can't account for the CT finding, then yes. Ultrasound would likely be the next test, then possibly MRI if there is still uncertainty. ...Read more

I am 35 year old female. Had 6 CT plus 2 mammograms and a few x rays in the last 2 years. Just learned about radiation danger. Now I am terrified.What can I do to repair cell damage. Please so scared?

I am 35 year old female. Had 6 CT  plus 2 mammograms and a few x rays in the last 2 years. Just learned about radiation danger. Now I am terrified.What can I do to repair cell damage. Please so scared?

Radiation damage: The past is the past. Antioxidants and healthy living are the best recommendations for you. If down the road you get systemic symptoms such as weight loss or chronic headaches please see your physician. An MRI is a radiation free test that if you need one you should have instead of ct or x-ray. Relaxation techniques may be of benefit to you as well. ...Read more

Lesion on mammogram. Nodule on xray. Clear ct. Swollen lnodes. Likely cancer? Lump w/o mobility nor pain. Pain @ site of nodule. Biopsy? Smoker 20 yr

Hard to tell: whether these findings are related or not. All need to be evaluated. Is the mammo lesion the same as the lump? What is the radiologist's recommendation? Is there a lung nodule? Speak with your doctor about all of these results, and the next steps. ...Read more

Mammogram yearly @ 65? Since 35, diagnostic, reg mam & ultrasound. Dx yrs ago fibrocystic. Punctuate calcifications both breasts. CT MRI 2xyr re CRC.

Mammogram yearly @ 65? Since 35,  diagnostic, reg mam & ultrasound. Dx yrs ago fibrocystic. Punctuate calcifications both breasts. CT MRI 2xyr re CRC.

Calcifications: Microcalcifications of the breasts are suspicious findings and usually require a minimally invasive breast biopsy. The majority of the biopsies will return a benign result but we can't assume that based on mammogram. MRI use in the US is very user dependent and should be reserved for high risk individuals or those with a proven cancer. ...Read more

Mammogram, ct, MRI and ultrasound tests for breast cancer - what is best?

Mammogram, ct, MRI and ultrasound tests for breast cancer - what is best?

Situational: For screening: mammograms are the most valuable. For diagnosis (palpable mass, mammographic density): ultrasound can be very helpful. Mris are the most sensitive test for breast cancer, but their prohibitive cost makes this unaffordable for large-population screening. It is best used in high-risk patients, those with very dense breast tissue, and for evaluating the extent of a known breast cancer. ...Read more

Upper back pain one year. Ct of chest in nov 12 ok. Mri spine ok. Could this be missed breast cancer? I had mammogram sept 12 ok. Not present at rest

No, not Realy: Pain in the back with movement is usually linked to posture of the spine or ribs. Cancer at your age is usually found within the breast, and the testing you have undergone already is reassuring. Continue to be medically examined for your concern of cancer, but seek a musculoskeletal physician to help with your chest wall pain. ...Read more

Had a sore, very painful swollen knotted ab for 5 mos.Xrays, ct,lung scan, mamagram clear.Still no diagnosis. Would a MRI be too much radiation?

No radiation in MR: MRI uses magnets and radio waves, no x ray dose at all. MRI is an excellent tool for soft tissue mass eval. Lung scan for a "knotted ab" suggests that your history is more complex, so work with your provider. ...Read more

I have had 2 cat scans and have multiple lung nodules with no changes in the last 6 months. Mammogram and colonoscopy are good. I am a 37 yr f.

The lack of change: of the lung nodules suggests they are benign. There may still need to be additional follow up for a year or two to confirm it, so speak with your doctor. ...Read more

How likely am i to have a malignancy. Up rt back pain deep in shoulder chest CT ok. Throstic MRI ok. Mamagram ok. Us right breast ok. Temps off and on?

Sounds very unlikely: All your imaging studies are normal, so likelihood of malignancy seems incredibly low. You might investigate this pain as musculoskeletal. Very common to have pain on the medial, or inside portion of the scapula, where it attaches to the vertebral column. A chiropractor or massage therapist might be of help to help isolate this pain and address it musculoskeletally. Just an idea. ...Read more

Does a positive magea4  melenoma antigen gene suggest that I do have  cancer? Ct of lungs clear. Mamaagram clear. Ct of pelvis and abdomen clear.

No one knows: Magea4 is an as of yet unproven tumor marker. I'm not sure why it was tested in your case. An elevated level does not mean that you have cancer. The test is simply not that sensitive or specific. ...Read more

What happens if an ultrasound scan seems clear is it possible that a mammogram will still show a problem?

What happens if an ultrasound scan seems clear is it possible that a mammogram will still show a problem?

Yes,: they are complementary tests. At times an abnormality will be seen on one, and not the other. In particular, mammographic microcalcifications, which can be a sign of cancer, are difficult to discern on an ultrasound. ...Read more

Should I be seeking a second opinion when the radiologist stated an area on my baseline breast scan to be within normal tissue after a repeat mammogram and ultrasound? He would like to see me again in 6 months to compare scans.

Should I be seeking a second opinion when the radiologist stated an area on my baseline breast scan to be within normal tissue after a repeat mammogram and ultrasound? He would like to see me again in 6 months to compare scans.

Check with your Doc: A mammogram is a screening tool & an ultrasound and magnified views of a breast area would have given the radiologist more information. If no concerning areas are found, your doc has to correlate your risk factors with your clinical exam to decide if a repeat in 6 months is appropriate. Do this first & if still concerned, then feel free to seek a second opinion. Take good care of yourself. ...Read more

Mammogram (Definition)

A mammogram is the "gold standard" screening test for breast cancer. It's well established that yearly 'grams will DX cancers well before they are palpable, leading to earlier diagnoses and saved lives. All experts agree to begin yearly mammograms by age 50; many (including myself) believe the pro's outweigh the con's to begin at 40. Regrettably, less than half of all women ...Read more
