Positron emission tomography/magnetic resonance imaging (PET/MRI): An update and initial experience at HC-FMUSP

Summary The new technology of PET/MRI is a prototype of hybrid imaging, allowing for the combination of molecular data from PET scanning and morphofunctional information derived from MRI scanning. Recent advances regarding the technical aspects of this device, especially after the development of MRI-comp...

Interregional correlations of glucose metabolism between the basal ganglia and different cortical areas: an ultra-high resolution PET/MRI fusion study using 18F-FDG

Braz. j. med. biol. res; 51 (1), 2018
Basal ganglia have complex functional connections with the cerebral cortex and are involved in motor control, executive functions of the forebrain, such as the planning of movement, and cognitive behaviors based on their connections. The aim of this study was to provide detailed functional correlation pa...

PET/MRI: a novel hybrid imaging technique. Major clinical indications and preliminary experience in Brazil

Einstein (Säo Paulo); 15 (1), 2017
ABSTRACT In recent years, medical imaging with hybrid techniques has widely accepted and employed in clinical routine. PET/MRI offers significant advantages, including excellent contrast and resolution and reduced ionizing radiation, as compared to well-established PET/CT. Therefore, PET/MRI is a promisi...

Anatomo-radiological correlation using 18-FDG-PET in abdominal sepsis model in rats. A preliminary study

Acta cir. bras; 32 (3), 2017
Abstract Purpose: To examine a correlation of micro-PET images with photographic images of the digestive organs in abdominal sepsis model. Methods: Male Wistar rats weighing 265±18g were used. Abdominal sepsis was induced by ligature and cecal puncture. Micro-PET Images from abdominal cavity septic f...

Doenças autoinflamatórias em adultos: abordagem prática ao diagnóstico baseada em um caso clínico

As doenças autoinflamatórias são doenças inflamatórias raras cujo cerne imunológico baseia-se na imunidade inata. A maioria das doenças autoinflamatórias tem início na idade pediátrica, mas pouco se sabe sobre as doenças que se iniciam na vida adulta. O diagnóstico é feito por exclusão, e, ...

Estudos de aterosclerose experimental utilizando tomografia por emissão de pósitrons ( PET-Scan )

A aterosclerose é caracterizada como uma doença imune-inflamatória crônica das artérias devido ao grande acúmulo de lipídios na íntima. Um dos fatores envolvidos na progressão da aterosclerose é a presença de uma subfração de partículas de lipoproteína de baixa densidade (LDL) com um grau ...
