State of the art in vulvar cancer imaging
Abstract Vulvar carcinoma is an uncommon tumor that predominantly affects postmenopausal women. Currently, there is no screening procedure for vulvar carcinoma; in most cases, it is diagnosed only when symptoms appear. The most widely used staging system is that developed by the International Federation of Gynecology and Obstetrics. Lymph node status is the most important prognostic factor. We searched the PubMed/Medline database to identify relevant English-language articles on vulvar cancer, with a special focus on its imaging evaluation. Magnetic resonance imaging is useful for local and nodal staging, as well as facili...

Accuracy of breast magnetic resonance imaging in evaluating the response to neoadjuvant chemotherapy: a study of 310 cases at a cancer center
Conclusion: Breast MRI showed good accuracy in the prediction of a pathological complete response after NAC. The sensitivity and positive predictive value were highest for the HER2 and triple-negative subtypes.Resumo Objetivo: Avaliar a acur ácia da ressonância magnética (RM) das mamas na identificação de resposta patológica completa em pacientes com câncer de mama submetidas a quimioterapia neoadjuvante (QTN). Materiais e Métodos: Teste de validação diagnóstica, realizado por meio de estudo observacional, unicêntrico e ret rospectivo.

Quantitative evaluation of brain volume among elderly individuals in São Paulo, Brazil: a population-based study
Conclusion: We have corroborated the findings of studies conducted in the United States and Europe. The total brain volume/intracranial brain volume ratio is higher in men, representing a potential bias for the conventional radi ological assessment of atrophy, which is typically based on the evaluation of the cerebrospinal fluid spaces.Resumo Objetivo: Analisar, quantitativamente, o volume cerebral de idosos em uma amostra de base populacional em S ão Paulo. Materiais e Métodos: O estudo é uma avaliação radiológica e análise quantitativa baseada em voxel com alinhamento de superfície de 525 imagens de ressonâ...

Microvascular invasion in hepatocellular carcinoma: is it predictable with quantitative computed tomography parameters?
Conclusion: Quantitative dynamic CT parameters measured in the preoperative period do not appear to correlate with MVI in HCC.Resumo Objetivo: O objetivo deste estudo foi investigar se par âmetros quantitativos da tomografia computadorizada (TC) podem predizer invasão microvascular (IMV) no carcinoma hepatocelular (CHC). Materiais e Métodos: Foram analisados, retrospectivamente, 200 CHCs comprovados de 125 pacientes submetidos consecutivamente a transplante ou ressecção hepáti ca entre março/2010 e novembro/2017. Foram realizadas medidas quantitativas da densidade das lesões e do parênquima hepático adjacent...

Differences in negative predictive value of prostate MRI based in men with suspected or known cancer
Conclusion: The NPV of multiparametric MRI for GS ≥ 3+4 is higher in men with suspected prostate cancer than in men under AS. PSA density ≤ 0.15 improved the prediction of intermediate to high-grade disease in patients without known cancer.Resumo Objetivo: Comparar o valor preditivo negativo (VPN) da RM multiparam étrica da próstata para o diagnóstico de tumores escore de Gleason (EG) ≥ 3+4 e avaliar os preditores desses tumores em homens com suspeita de doen ça e nos sob vigilância ativa (VA). Materiais e Métodos: Este estudo retrospectivo incluiu 38 homens com suspeita de câncer de próstata e 38 em VA ...
