Nuclear imaging for functional evaluation and theragnosis in liver malignancy and transplantation

Figure 4 Pretreatment planning and post-treatment evaluation using single photon emission computed tomography and positron emission tomography. In a patient with a large hypervascular tumor in the right lobe of the liver (A; contrast-enhanced CT), pretreatment SPECT/CT using ^99mTc-labeled macroaggregated albumin shows well-localized accumulation of the radiotracer (B). After treatment evaluation using ⁹⁰Y-microsphere, ⁹⁰Y PET/CT image shows a similar uptake pattern in the liver (C). SPECT: Single photon emission computed tomography; CT: Computed tomography; PET: Positron emission tomography.
