Your report said no evidence of FDG avid disease, this means no uptake, no cancer reacting to the tracer. The uptake value is not always an indication of progression or a success rate. Its not a black and white indication. To confirm, an FDG PET scan is performed. [DocPanel] What role does an FDG PET scan play in cancer staging? Google Scholar.
