(5.1) A(t) = the radioactivity at time t. A 0 = the radioactivity at time t = 0. λ = the decay constant characteristic of each radionuclide. e = the…

Fig. 16.1 Incorrect quantification of the 18F-FDG activity in the brain due to the head motion causing misregistration between the CT and PET on the left. Software registration of the…

Fig. 12.1 The two rows, referring to an individual patient with primary cervical cancer, show texture maps for FDG (metabolic marker) and Cu-ATSM (hypoxia marker) alone and overlapping texture maps…

Fig. 18.1 A 67-year-old man had a right upper lobe NSCLC resected. (a) FDG-PET/CT scan (i) MIP, (ii) PET, (iii) CT and (iv) fused PET/CT axial images through the thorax…

Fig. 9.1 The model implemented in Philips PET/MR system. The two modules are located at adequate far distant apart, minimizing mutual interference between the two systems, and data are acquired…

Fig. 22.1 Image fused 4D-PET/CT of patient with pancreatic tumor for radiotherapy planning. Standard planning target volume (STD-PTV) is correlated with 4D-CT image (red outlines) and 4D-planning target volume (4D-PTV)…

where D T = absorbed dose (Gy) in target organ T Ã S = the number of nuclear transitions in a source organ S, sometimes referred to as the “cumulated…

Fig. 17.1 A young male patient with a mediastinal germ cell tumour. 18F-FDG-PET/CT (a) and PET/MRI (b) transaxial images through the upper thorax 17.3 Underlying Tumour Biology and FDG The…

Fig. 13.1 The figure shows the structure of three-compartment model to quantitatively assess the transportation rate constants related to FDG metabolism, where Cp, C1, and C2 are the compartments for…

Fig. 20.1 For orientation, macroanatomical structures are delineated on the left hemisphere of the Collin standard brain. Shown are a view from mesial (left), two axial sections 11 mm below…
