The other potential application of the Axumin scan, apart from its usefulness for determining the area of PSA relapse, is for men who have undergone chemo-hormonal treatment for advanced metastatic disease. The beauty of the Axumin PET scan is that it offers the possibility of detecting small metastatic lesions in the lymph nodes with PSA levels in the 1 to 10 range. It came back with no hot spots. According to an article recently published in the Journal of the National Cancer Institute, positron emission tomography (PET) scans may improve the accuracy of imaging in lung cancer. Therefore, PET/CT colonography may be considered at least as accurate as CT + PET in patients with colorectal cancer. Choi JE. • CT/MRI and bone scan are not recommended for prostate cancer staging until PSA level has reached 10 or 20 ng/mL because of low accuracy and sensitivity (Wollin et al, BJU Int.
