How effective are CT scans in finding nodules?
After two chest X-rays on the same week showed a 5MM benign module I went for a CT scan which did not even show the nodule anymore. They think it was just a blood vessel showing on both X-rays. But Doctor also did blood work. All is normal. She said no more follow up needed. But I'm wondering if maybe the CT scan just missed the module and if I should have this situation checked out again in a year or so. Smoker no more.
Hi.
Not all CT scans are the same, so there are some differences with their abilities. In general CT scans can detect changes as small as 3-5 mm, whereas a high-resolution scan can detect measurements up to 0.3 mm. I think its unlikely that the repeat would miss it. Take note also that the description on the initial scan was benign (so its no surprise that it is not there anymore) - if this was read as suspicious for malignancy, then more testing may have been recommended.
Screening for Lung cancer is still controversial - it has not shown clear advantages, and there is a concern of radiation exposure from CT scans. Work is being done however, inquire from your doctor if there is a chance for you to participate in studies done in academic centers to address this specific issue.
Stay positive.
