Is image guided sinus surgery like having another CT scan of head/sinuses? Should one worry about commulative radiological exposure?
Yes and no: Image guided sinus surgery allows your surgeon to more accurately identify where they are working in an effort to reduce the chance of surgical injury and to assure that the sinus issues you suffer from are treated as effectively as possible. This does require additional radiation exposure for the scans, something that one should keep to a minimum. For many, benefits outweigh the risk. ...Read moreSee 2 more doctor answers
Ct scan 2013 no nodules-2 on CT scan 10/2014 ago-ct scan 11/2014 3 nodules-all around 5 mm-diagnosed w/stage 1b breast ca 9/2013 triple+ is this mets?
Suspicious for mets: Your doctor can verify and confirm it one of two ways. Do a PET scan now or do one more CT scan of chest in 6-8 weeks from now. Biopsy may be needed but the nodules are too small for a biopsy right now...they need to be close to 10-12 mm in size. Good luck. ...Read moreSee 1 more doctor answer
Should I do & how much radiation CT scans for one dental implant causes vs regular chest/head CT scan or one digital tooth x ray. I am curious to know
Radiation dose chart: We only want to take the minimum number and type of x-rays or scans in order to properly diagnose and treatment plan. Without that we might either miss something or the final result might be compromised. Here is a good website for you to look at: http://www.Ans.Org/pi/resources/dosechart/. ...Read moreSee 2 more doctor answers

In : In a word, no. A single ct scan is exceedingly unlikely to cause you any problem of any kind at any point in your life. It is not possible to say that there is no risk at all, because any exposure to radiation (including cosmic radiation from the sun or from naturally occurring radiation that's all around us) can potentially cause a cancer. ...Read moreSee 1 more doctor answer

Ct scan false negative? 2012 renal US found 5mm solid lesion (likely aml). New US found bilateral lesions, avascular. 5mm now 7mm. New 1cm, CT normal
Renal cysts: Renal cysts are common in people over the age of 50, and are not significant. I don't know what AML stands for. A solid lesion needs a repeat study after a few months to show that it is not getting larger. You should review the CT report with your physician ...Read more
My dad 73 yr old quit smoking 18 yr old. His CT scan shows infection & one 7 mm nodule. Should we go for pet scan or biopsy? Any pros cons of each?
Comparisons?: 1st, are there any old cds to compare? If so, is the nodule truly new? The 7 mm nodule could be infectious. Consider waiting a month and repeating the ct scan. Given remote smoking history and nodule size, would lean towards pet/ ct 1st. Biopsy may still be needed to prove cause. ...Read moreSee 2 more doctor answers
Is this too much in a 2 month period, 1 pet scan, i ct, 6 x-rays , a brain scan now doctors wants another pet .Lung nodule 1.4 -2.7 suv?
My sister had a uppper rt lung lobectomy last year ...Has non small cell adeonocarcinoma....Ct scans and pet scans every 3 months...Past 2 recent CT scans plus pet scan are showing an increased pleural based nodular density in the rt lower lobe anteriorly
Could be recurrence: This needs to be worked up - it could be recurrent cancer, or possibly reactive, especially if radiation therapy was performed. See the oncologist and ask for specifics about this finding. Was the pet scan positive in the same area? If so, that raises the concern, but it still could be reactive. ...Read moreSee 1 more doctor answer
No: SUV has no bearing on the aggressiveness of the cancer. It is a relative measure of the glucose metabolism. In fact, some very aggressive tumors have no FDG uptake at all. Some benign conditions like infection can have high uptake. The standard uptake value depends on many factors like patient body size and serum glucose level and the normal uptake in the tissue surrounding the target lesion. ...Read more

What can one do to minimize negative impact of CT scan on body if one has already had abdominal ct scans?
CT Scan: Other than avoiding CT scans when possible when a non-radiation imaging study is possible (MRI or ultrasound), would ensure a very good hydration status before and after scan to help clear the IV contrast through your kidneys. Regarding the oxidative stress during CT scan, some would also recommend good nutrition status and a vitamin supplement prior to scanning. ...Read more
No, not even 2 scans: Patients get CT scans all over the world, every day. As long as there is a good reason for the scan, it is fine to do. If repeated scans are planned, to follow some sort of serious illness, a patient can ask his doctor what other options there are, in order to decrease the total number of scans in his lifetime. Having repeated CT scans, over and over, can add up to too much x-ray exposure. ...Read more
