Hounsfield unit value has null effect on thyroid nodules at 18F-FDG PET/CT scans

ABSTRACT Objectives: Detection rate of thyroid nodules is increasing with the use of new imaging modalities, especially in screening for malignancies. Positron emission tomography/computed tomography (PET/ CT)-positive thyroid nodules should be differentiated for malignancy to avoid unnecessary operatio...

Practical Implications of Myocardial Viability Studies

Arq. bras. cardiol; 110 (3), 2018
Abstract Many non-invasive methods, such as imaging tests, have been developed aiming to add a contribution to existing studies in estimating patients' prognosis after myocardial injury. This prognosis is proportional to myocardial viability, which is evaluated in coronary artery disease and left ventric...

Individualized threshold for tumor segmentation in 18F-FDG PET/CT imaging: The key for response evaluation of neoadjuvant chemoradiation therapy in patients with rectal cancer?

Summary Introduction: The standard treatment for locally advanced rectal cancer (RC) consists of neoadjuvant chemoradiation followed by radical surgery. Regardless the extensive use of SUVmax in 18F-FDG PET tumor uptake as representation of tumor glycolytic consumption, there is a trend to apply metabol...

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...

Clinical perspectives of PSMA PET/MRI for prostate cancer

Clinics; 73 (supl.1), 2018
Prostate cancer imaging has become an important diagnostic modality for tumor evaluation. Prostate-specific membrane antigen (PSMA) positron emission tomography (PET) has been extensively studied, and the results are robust and promising. The advent of the PET/magnetic resonance imaging (MRI) has added m...

Rev. chil. pediatr; 88 (6), 2017
Resumen El cáncer en la población pediátrica representa la segunda causa de muerte en niños mayores de 5 años en nuestro país, después del trauma. La tomografia por emisión de positrones/tomograña computada (PET/CT) es una técnica hibrida que involucra radiación y que progresivamente se está ...

Avaliação das cardiopatias congênitas no adulto: ecocardiografia, ressonância e tomografia

Avanços recentes na cardiologia pediátrica permitem que uma população crescente com cardiopatias congênitas chegue à idade adulta, muitos deles necessitando de seguimento por toda a vida. Um elemento chave desse seguimento é a avaliação seriada com métodos diagnósticos por imagem. O cardiologi...
