Introduction: Prostate-specific antigen (PSA) kinetics (PSA velocity [PSAV] and PSA doubling time [PSADT]) are predictors of positivity in Choline PET/CT, but this correlation has not been correctly established in PSMA PET/CT. Objective: To evaluate the diagnostic correlation between PSA kinetics and positivity of 18F PSMA PET/CT in patients with relapsed prostate cancer (RPC). Material and methods: We performed an observational cross-sectional study of 54 patients with RPC that were evaluated with 18F-PSMA PET/CT. The concordance between 18F-PSMA PET/CT and PSA kinetics was analyzed. Results: The mean age was 68 ± 8 years. Time to relapse had a median (Q1-Q3) of 29 (8; 48) months. The trigger PSA

Abstract The typical imaging appearance of hepatocellular carcinoma (HCC) is widely recognized and consists in hyper enhancement in the arterial phase with lavage in the portal and late venous phases, as on computed tomography (CT) as on magnetic resonance imaging (MRI). This pattern is observed in 60% of cases and has been incorporated into the diagnostics directi-ves of the different organizations which participates in the hepatic diseases studies and its presence avoid the necessity of a biopsy. Besides, are auxiliar signs useful on the HCC diagnostic, T2 hyperintensity, presence of grease, venous tumor thrombosis and the growth between intervals in follow up studies. However, not all HCC patients harbor these characteristics and in 40% of cases the atypical introduction proposes a diagnostic and handling challenge of patients.

Resumen Introducción: La imagen ponderada en difusión es una técnica de imagen funcional que aporta información complementaria a las secuencias convencionales de resonancia magnética. El coeficiente de difusión aparente (CDA) se valora junto con la secuencia de difusión, calculando el logaritmo negativo de la proporción de intensidades de dos conjuntos de imágenes, lo que permite el análisis cuantitativo de la restricción a la difusión. Objetivo: Determinar si existe una diferencia significativa entre los valores de CDA de las lesiones musculoesqueléticas benignas y malignas, correlacionando los resultados con los hallazgos histológicos. Método: Estudio prospectivo, observacional y descriptivo. Se incluyeron en el trabajo pacientes con sospecha de lesiones tumorales del sistema musculoesquelético de cualquier edad y sexo, sin antecedentes de radioterapia previa o cirugía, evaluados con resonancia magnética y con posterior biopsia o cirugía. Resultados: Se incluyeron 170 pacientes, de los cuales 80 (44 benignos) eran hombres y 90 (43 benignos) eran mujeres. El total fue de 87 lesiones benignas y 83 lesiones malignas, con Abstract Introduction: Diffusion-weighted imaging is a functional imaging technique that provides complementary information to conventional magnetic resonance imaging sequences.
