Positron emission tomography combined with computed tomography (PET/CT) is a method, capable of evaluation of not only structural, but also metabolic alterations in organs and tissues. 18F-fluorodeoxyglucose (18F-PDG) PET/CT is widely used in diagnostics of various malignant tumors, but its role in renal cell carcinoma (RCC) remains obscure.Despite its limited effectiveness in primary and differential diagnosis of RCC, PET/CT can be used to determine the grade of malignancy and the histological type of tumor. According to various authors, 18F-FDG standardized uptake value (SUV) of a renal neoplasm can serve as an independent prognostic factor of overall survival.18F-FDG PET/CT is widely used to detect local recurrence and metastatic lesions in various neoplastic processes. Numerous studies confirm the high efficiency of PET/CT in detection of metastases and recurrence discernment for RCC.The ability to assess the metabolic activity of neoplastic foci using PET/CT may allow for evaluation of RCC therapy effectiveness, which is confirmed by clinical studies of various targeted therapy agents, such as tyrosine kinase inhibitors, mammalian target of rapamycin inhibitors, and monoclonal antibodies.Thus, there is growing evidence that 18F-FDG PET/CT is a useful tool in diagnostics of RCC.ΠΠΎΠ·ΠΈΡΡΠΎΠ½Π½Π°Ρ ΡΠΌΠΈΡΡΠΈΠΎΠ½Π½Π°Ρ ΡΠΎΠΌΠΎΠ³ΡΠ°ΡΠΈΡ, ΡΠΎΠ²ΠΌΠ΅ΡΠ΅Π½Π½Π°Ρ Ρ ΠΊΠΎΠΌΠΏΡΡΡΠ΅ΡΠ½ΠΎΠΉ ΡΠΎΠΌΠΎΠ³ΡΠ°ΡΠΈΠ΅ΠΉ (ΠΠΠ’/ΠΠ’), ΡΠ²Π»ΡΠ΅ΡΡΡ ΠΌΠ΅ΡΠΎΠ΄ΠΎΠΌ ΠΎΡΠ΅Π½ΠΊΠΈ Π½Π΅ ΡΠΎΠ»ΡΠΊΠΎ ΡΡΡΡΠΊΡΡΡΠ½ΡΡ

Low-Energy Optical Conductivity of TaP: Comparison of Theory and Experiment
The ab-plane optical conductivity of the Weyl semimetal TaP is calculated from the band structure and compared to the experimental data. The overall agreement between theory and experiment is found to be best when the Fermi level is slightly (20 to 60 meV) shifted upwards in the calculations. This confirms a small unintentional doping of TaP, reported earlier, and allows a natural explanation of the strong low-energy (50 meV) peak seen in the experimental ab-plane optical conductivity: this peak originates from transitions between the almost parallel non-degenerate electronic bands split by spin-orbit coupling. The temperature evolution of the peak can be reasonably well reproduce by calculations using an analog of the Mott formula
