Does decreased skeletal uptake of 99mTc-methylene bisphosphonate in irradiated bone indicate the absence of bone metastases?
Reduced uptake of 99mTc-methylene bisphosphonate (99mTc-MBP) was found in irradiated bone in all of 13 tumour-free patients who had undergone radiotherapy (30-40 Gy) due to seminoma 3-8 years prior to bone scintigraphy. Decreased uptake of 99mTc phosphate compounds can not per se be interpreted as a sign of absence of metastases or reduced tumour burden.
