(a) Baseline PET/CT images obtained in a Biograph Duo LSO (Siemens) 75 minutes after injection of 405 MBq of ¹⁸FLT in a 47‐year‐old woman with a right‐sided infiltrating ductal carcinoma (SUVmax = 5.42) (arrow) and lymph node uptake (SUVmax = 1.85) (arrowhead). Physiological bone marrow uptake was identified. (b) PET/CT images obtained 75 minutes after injection of 529 MBq of ¹⁸FLT after one cycle of neoadjuvant therapy. SUVmax decreased to 3.57 in the primary tumor and to 0.80 in the lymph node, consistent with metabolic response.
