- Dynamic patterns of [ 68 Ga]Ga-PSMA-11 uptake in recurrent prostate cancer lesionsAbstract Purpose Dual-time point PET/CT scanning with [68Ga]Ga-PSMA-11 in the diagnosis of prostate cancer (PC) has been advanced as a method to increase detection of PC lesions, particularly at early stages of biochemical recurrence and as a potential means to aid the discrimination between benign and pathological prostate-specific membrane antigen (PSMA) uptake. However, the assumpti
- Adaptive phase correction of diffusion-weighted imagesPublication date: Available online 17 October 2019Source: NeuroImageAuthor(s): Marco Pizzolato, Guillaume Gilbert, Jean-Philippe Thiran, Maxime Descoteaux, Rachid DericheAbstractPhase correction (PC) is a preprocessing technique that exploits the phase of images acquired in Magnetic Resonance Imaging (MRI) to obtain real-valued images containing tissue contrast with additive Gaussian noise, as opposed to magnitude images which follow a non-Gaussi
- Brain networks, dimensionality, and global signal averaging in resting-state fMRI: Hierarchical network structure results in low-dimensional spatiotemporal dynamicsPublication date: Available online 17 October 2019Source: NeuroImageAuthor(s): Stephen J. Gotts, Adrian W. Gilmore, Alex MartinAbstractOne of the most controversial practices in resting-state fMRI functional connectivity studies is whether or not to regress out the global average brain signal (GS) during artifact removal. Some groups have argued that it is absolutely essential to regress out the GS in order to fully remove head motion, respiratio
- Relationships between depressive symptoms and brain responses during emotional movie viewing emerge in adolescencePublication date: Available online 16 October 2019Source: NeuroImageAuthor(s): David C. Gruskin, Monica D. Rosenberg, Avram J. HolmesAbstractAffective disorders such as major depression are common but serious illnesses characterized by altered processing of emotional information. Although the frequency and severity of depressive symptoms increase dramatically over the course of childhood and adolescence, much of our understanding of their neurobi
- Radioembolización en tumores hepáticosPublication date: Available online 16 October 2019Source: Revista Española de Medicina Nuclear e Imagen MolecularAuthor(s): L. Carrion-Martin, J. Orcajo Rincón, A. Rotger, M. Gonzalez-Leyte, L. Márquez Pérez, M. Echenagusia, A. MatillaResumenLa enfermedad hepática tumoral es cada vez más frecuente. Su peculiar forma de irrigación, predominantemente arterial, a diferencia del resto del hígado con flujo fundamentalmente por vía portal, hace a los t
