Radioembolization images. Different imaging sessions for two patients (A and B) with HCC: 99mTc-MAA SPECT (left), bremsstrahlung SPECT (center), and 90Y-PET (right). The reference lines cross a tumor lesion for the two patients. Imaging sessions for the second patient (B) show a clear discrepancy between pre-therapeutic (left) and post-therapeutic (right) imaging sessions. Tumor uptake was detected with 90Y-PET (right) but not with bremsstrahlung SPECT (center). Measurement of the tumor lesion for patient B is illustrated in red (right).
