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
Metastases: PET CT is often utilized to identify metastases from melanoma. Utilizes isotope F18 FDG for glucose metabolism of malignant lesions to identify them. Most malignant neoplasms have increased metabolic activity. CT portion compares anatomic lesion with area of increased uptake shown by PET. ...Read moreSee 2 more doctor answers
My father has metastatic melanoma, 1 lymph node involvement. Pet scan and CT scan shows no other metastasis at this time. Does this mean he is cured?
Melanoma...: Melanoma is a very tricky disease and must be followed closely. It can metastasize to odd places. It is good news that only 1 lymph node is seen on pet/ct rather than many lymph nodes but one should note that micrometastases or very small lesions may be below the resolution of pet imaging. ...Read moreSee 1 more doctor answer

What is the likelihood of a new subpleural nodule (1 cm by 1 cm) being malignant? Showed up in annual CT scan. Have had sarcoma, breast, and melanoma
It depends1: In a patient with prior history of cancer, lung or pleural based nodule can be due to cancer especially if the nodule is new(not seen in prior CT scan/s of your chest). A short follow up CT scan(2 monts from now) can be very helpful to determine if it is growing in which case it would indicate likely metastasis from one of your previous cancers. PET scan is another test that can helpful to define ...Read more

Hypothetically if somebody had melanoma on their lower back and had a CAT Scan of abdomen and pelvis 4 other reasons.Would melanoma show up on CAT?
It could: potentially show up on an abdomen/pelvis CT, depending on the size. There are no specific features of melanoma on CT, so, if small, it would look the same as the myriad of benign nevi, keratoses, cysts, etc... that are so common, and might not be mentioned as a relevant finding in the report. ...Read moreSee 1 more doctor answer
What is the risk that an adult who is 29yr old will get (blood/lung/skin) cancer from one chest CT scan?
0.05-0.25%: Nicely discussed here: http://www.Scientificamerican.Com/article/how-much-ct-scans-increase-risk-cancer/ however, there is no real science at the low doses used in medicine. This number is extrapolated from a higher dose measure with the assumption it will be the linear relationship at the lower dose level. ...Read more
Should i be concerned about a positive mage a 4 test? Mage= melenoma antigen gene? I had early cdt lung cancer blood test. Ct of lungs clear
MAGE A4 Tesring : The mage a4 antigen, even though it was named the melanoma associated antigen, is a non-specific antigen that has been linked to a wide variety of tumors. It's efficacy is still being debated as a stand alone predictor. Your physician should investigate and rule out the most likely malignancies for your age and family history, including early breast and oral cancer, as well as others less likely. ...Read moreSee 1 more doctor answer
What would cause a pet scan to not detect malignant melanoma that was about the size of a chocolate easter egg? I also have type II diabetes.
Many Factors: No test is always right, pet/ct included. Every patient's tumor is unique, too. How a particular tumor will take up the primary pet/ct tracer, called f-18 fdg, is also not perfectly known. Some consistently fail to take up FDG that pet/ct is rarely used to image them, but this is not true for melanoma. Finally, smaller tumors are always harder to see, no matter which imaging technique is used. ...Read moreSee 1 more doctor answer

Diagnosed- malignant melanoma 5/2017 Diagnosed - treated for anal cancer 5/2016. Pet scan done in March '16. If MM has spread, wouldn't PET scan show?
PET scan is a good t: PET scan is a good test to detect metastatic cancer. In fact it is our best imaging test to catch metastases early. Yet it has some limitations in that it can not show microscopic tumors/ small # of cells in the body...it only shows tumors that are bigger than half a centimeter (>5 mm). That is why this test has to be repeated every 3 to 4 months when there is a risk for the tumor to come back. ...Read more
