Valor del PET/CT semicuantitativo (SUVmax) en el estudio de nódulo pulmonar sólido

OBJETIVO: Determinar el rendimiento diagnóstico del PET/CT en el estudio de nódulo pulmonar (NP) utilizando SUVmax. MÉTODO: Se revisó la base de datos de PET/CT, seleccionando aquellos solicitados para estudio de NP sólido. Se incluyeron sólo aquellos NP confirmados como malignos o benignos. Se ex...

Enhancing PSMA-uptake with androgen deprivation therapy - a new way to detect prostate cancer metastases?

Int. braz. j. urol; 45 (3), 2019
ABSTRACT Purpose: 68Ga-PSMA PET/CT imaging is a promising modality for the staging of recurrent prostate cancer (PCa). Current evidence suggests limited diagnostic value of the 68Ga-PSMA PET/CT in PSA-levels ≤0.3ng/mL. Experimental data have demonstrated an increase in PSMA-expression in PCa metas...

Utilidad de la 18f-colina pet/tc en hiperparatiroidismo primario persistente o recurrente: experiencia inicial
Usefulness of 18f-choline pet / tc in persistent or recurrent primary hyperparathyroidism: initial experience

Actual. osteol; 15 (1), 2019
El hiperparatiroidismo persistente/recurrente representa un desafío en la localización del tejido paratiroideo hiperfuncionante. En esta subpoblación, los métodos convencionales ofrecen un menor rédito diagnóstico. La 18F-colina PET/TC podría ser una buena alternativa dada su mejor resolución esp...

PET/CT com 18F-FDG como ferramenta de avaliação do desenvolvimento de carcinoma hepatocelular secundário a doença hepática gordurosa não alcoólica em modelo experimental

Arq. gastroenterol; 56 (1), 2019
ABSTRACT BACKGROUND: Hepatocellular carcinoma (HCC) can be the last step of non-alcoholic fatty liver disease (NAFLD) evolution. Experimental models are crucial to elucidate the pathogenesis of HCC secondary to NAFLD. The 2-deoxy-2-(18F)fluoro-D-glucose (18F-FDG) positron emission tomography/computed t...

Dramatic polarization in genitourinary expert opinions regarding the clinical utility of positron emission tomography (PET) imaging in prostate cancer

Int. braz. j. urol; 45 (1), 2019
ABSTRACT Objectives: To ascertain the opinions of North American genitourinary (GU) experts regarding inclusion of technologies such as prostate - specific membrane antigen (PSMA) and C - 11 choline positron emission tomography (PET) into routine practice. Materials and Methods: A survey was distribute...

PET-CT para el manejo de pacientes con cáncer testicular tipo seminoma con masa residual post quimioterapia

Medwave; 19 (4), 2019
INTRODUCCIÓN En pacientes con cáncer testicular avanzado tipo seminoma que tienen lesiones residuales post quimioterapia de más de 3 cm, el PET-CT podría seleccionar un subgrupo susceptible de ser manejado con seguimiento, evitando una resección quirúrgica innecesaria de tumor no viable. MÉTODOS R...

Dynamic 11C-Choline PET / CT for the primary diagnosis of prostate cancer

Int. braz. j. urol; 44 (5), 2018
ABSTRACT Objectives: To test the ability of dynamic 11C-PET / CT to discriminate cancerous tissue from background tissue in patients with localized prostate cancer. Materials and Methods: Twenty-four consecutive patients with prostate cancer were prospectively evaluated with dynamic 11C-choline PET / C...

Impact of 68GA-PSMA PET / CT on treatment of patients with recurrent / metastatic high risk prostate cancer - a multicenter study

Int. braz. j. urol; 44 (5), 2018
ABSTRACT Purpose: The purpose of our study was to evaluate the clinical impact of 68Ga-PSMA PET / CT in the setting of biochemical recurrence of prostate cancer. Materials and Methods: We retrospectively evaluated 125 prostate cancer patients submitted to the 68Ga-PSMA PET / CT due to biochemical recur...
