I had a PET Scan performed yesterday. I have a nodule that was 7 mm in 2009 and now is 11 mm in 2011. The PET Scan said the SUV was 0.7. Since the nodule in 4 mm larger than 2 years ago they have recommended a biopsy and want me to see a Thorsaic Surgeon. This is never ending for me. 4 CT Scans later and a PET Scan and still cannot tell what the nodule is and I still need a biopsy. What is SUV 0.7? I am a former smoker. Thanks.
