Table 5 Comparison of Y-90 PET/CT vs. 99mTc-MAA imaging-based LSFs for the 20 patients that had post-therapy imaging

From: The value of 99mTc-MAA SPECT/CT for lung shunt estimation in 90Y radioembolization: a phantom and patient study

  LSF, mean (range) P * Maximum absolute difference in LSF (%)
99mTc-MAA planar imaging 4.1% (1.2–15.0) 0.0002 12.3
99mTc-MAA SPECT/CT (AC and SC) 1.0% (0.4–1.6) 0.968 1.6
90Y PET/CT 1.0% (0.3–2.8)   
  1. *P value for significance of difference between mean LSF from indicated method and Y-90 PET/CT
