Design and development of 6-hydrazinonicotinyl-fatty acid-mimetic 99mTc-complex as a potential myocardial imaging agent

Abstract The goal of this work is to identify new fatty acid-mimetic 99mTc-complexes to be used as myocardial imaging agents that allow studying heart abnormalities in high-risk patients. In this sense, we designed a fatty acid-mimetic substructure including an amide moiety that, among other properties, ...

Applicability of [18F]FDG/PET for investigating rosmarinic acid preconditioning efficacy in a global stroke model in mice

ABSTRACT Positron emission tomography (PET) is a non-invasive nuclear imaging technique that uses radiotracers to track cell activity. The radiopharmaceutical 18F-fluoro-2-deoxyglucose ([18F] FDG) is most commonly used in nuclear medicine for the diagnosis of various diseases, including stroke. A stroke ...

The impact of multimodality integrated positron emission tomography-computed tomography on improving the staging and management of head and neck malignancy: a cross- sectional study

Säo Paulo med. j; 140 (3), 2022
ABSTRACT BACKGROUND: Clinical assessment of head and neck cancers is highly challenging owing to the complexity of regional anatomy and wide range of lesions. The diagnostic evaluation includes detailed physical examination, biopsy and imaging modalities for disease extent and staging. Appropriate imagi...

Aporte de la centellografía con trazadores tecneciados fosfatados al diagnóstico de amiloidosis cardíaca

Rev. urug. cardiol; 37 (1), 2022
Las amiloidosis son enfermedades causadas por el depósito patológico extracelular de un material proteico fibrilar e insoluble denominado amiloide, que puede estar vinculado a cadenas livianas (AL) o transtirretina (TTR). La amiloidosis cardíaca provoca una cardiomiopatía restrictiva de carácter pro...

Aportes de la tomografía por emisión de positrones con 18F-fluorodesoxiglucosa/tomografía computada en el diagnóstico de compromiso extramedular por mieloma múltiple en Uruguay

Rev. méd. Chile; 150 (2), 2022
BACKGROUND: 18F-fluorodesoxyglucose positron emission tomography/ computed tomography (PET-CT) has a high sensitivity and specificity to detect medullary and extramedullary lesions in multiple myeloma (MM). AIM: To describe the findings of PET-CT in extramedullary multiple myeloma (EMM) at diagnosis and ...

Estratificação de Risco e Avaliação da Atividade Simpática Cardíaca Utilizando Imagem Miocárdica com [123I] MIBG na Denervação Renal

Arq. bras. cardiol; 118 (2), 2022
Resumo A hiperativação do sistema nervoso simpático desempenha um papel central na fisiopatologia da hipertensão. O objetivo deste estudo foi avaliar a atividade simpática cardíaca e investigar o papel da cintigrafia miocárdica com metaiodobenzilguanidina com 123I ([123I] MIBG) na estratificação...

68Ga-Prostate-specific membrane antigen (PSMA) positron emission tomography (pet) in prostate cancer: a systematic review and meta-analysis

Int. braz. j. urol; 47 (4), 2021
ABSTRACT Introduction: Prostate cancer (PC) is the second most commonly diagnosed cancer in males. 68Ga-PSMA PET/CT, a non-invasive diagnostic tool to evaluate PC with prostate-specific membrane antigen (PSMA) expression, has emerged as a more accurate alternative to assess disease staging. We aimed to ...

PET-CT FDG en el diagnóstico y seguimiento de vasculitis de grandes vasos

Rev. méd. Chile; 149 (5), 2021
Vasculitides are a broad group of diseases that can involve any kind of vessel in any organ. These can be classified according to the size of the affected vessels. The most used classification categorizes them in small, medium, and large vessel vasculitis. Large vessel vasculitis can be further divided i...
