Brief episodes of pulsatile tinnitus left ear only upon standing up? . Multiple normal 3t mri/a cta head neck for headaches. Normal BP and weigh.
CTA of head and neck. what are other scans that are useful with this CT technology that differs from MRI technology when scanning the brain/lympth ?
2 CTA & 9 head CT. Studies online say going to get brain cancer.upset.Thought only large radiation doses at once was bad. MD scared me over amount.
Can be a problem: Cumulative radiation exposure over time can increase your risk of getting cancer. At 38, you are young to have had so many CT's. You don't say what your symptoms are to drive so many tests, but if they are all done for the same symptoms and are repeatedly normal, I would stop getting them. ...Read moreSee 1 more doctor answer
I've had 6 CT scans in a year. Is this really dangerous for me? Should I be worried about getting cancer now? The CTa were: 1 head, 2 abdomen, 3 chest
Almost no risk of Ca: Please see: http://www.scientificamerican.com/article/how-much-ct-scans-increase-risk-cancer/ also: 1) Risk of induced Ca from 6 CTs is very, very low. 2) There may be cellular repair at doses as low as CT, limiting cancer induction. (We don't know how much). 3) Whatever the theoretical risk, there must be a good reason to do the CT in the first place. I would worry more about why so many CTs. ...Read more
Didn't know how dangerous head CTs were. 15-20 lifetime, 10 in past ten years, some w/ contrast. 1or2 CTA. What cancers am I at risk? How high Risk?
Low cancer risk: I can only estimate your exposure because it is dependent on the way the tests were done and your body size. More importantly is why the test was ordered. Both you and your doctor should consider the risk and benefit of each test. Did you talk to your doctors about this? Chances are that a test was important for your care and the risk was consider less than the need. see attached chart ...Read more
Had a lot of head CTs (7-8) & CTAs (2) due to TIA / stroke symptoms over the years and injuries associated to illness. Scared of brain cancer.
Induced Ca unlikely: I worry more about history of "TIA/stroke" and "injury" in a 38 yo. Radiation risk for the listed studies is well under 1 in 500 or so and "brain cancer" is even less likely. MRI is a great test for the brain and vessels as there is no ionizing radiation, BUT you must be able to have the test. For example no metal shavings in your eye from an injury and no unstable implanted ferrous metal. ...Read more
31/m c/o bilateral sharp CP x 6 mos., no known cause. Recent cta, ekgs, holter, echo, MRI chest, CT head are all negative. No prior history of any kind.?
Chest wall pain: A healthy 31 Y.O. Male with above testing all negative rules out most serious causes. What could be left includes a chronic pleurisy (perhaps part of a connective tissue disease), costochondritis (inflammation of the conncection between the bony and cartilage parts of the rib cage). Consider a routine dose of an anti-inflammatory medication with your md's advice. ...Read moreSee 1 more doctor answer
