Perforated Meckel's Diverticulum in an Adult
Camelo, R; Santos, P; Mateus Marques, RMeckel's diverticulum is the commonest congenital anomaly of the gastrointestinal tract. Its complications have an extensive variety of clinical and imaging manifestations, extending from benign and indolent findings to acute life-threatening conditions. Complicated Meckel's diverticulum often constitutes a challenging diagnosis for both the clinician and the radiologist. Therefore, imaging techniques play an i...
Ki-67 Proliferation Index in Gastric Cancer - Biologic Significance
Nabais, C; Caldeira Fradique, A; Oliveira, M; Quaresma, L; Gualdino Silva, J; Vasconcelos, V; Sacadura, J; Costa, L; Cabrita, F; Mateus Marques, RObjectives/Introdution: Ki-67 protein has been used as an indicator of proliferation activity in tumor cells. In gastric cancer the prognostic value has not been fully understood. This study was designed to assess the biologic significance of Ki-67 proliferation index (PI) in gastric cancer. Material/Methods: Seventy-two patients with gastric cancer were evaluated. These patients underwent gastric resection, an...

Post-Treated Prostate Cancer: Normal Findings and Signs of Local Relapse on Mul...
Lopes Dias, J; Lucas, R; Pina, J; João, R; Costa, N; Leal, C; Bilhim, T; Campos Pinheiro, L; Mateus Marques, RThe use of multiparametric magnetic resonance imaging (mp-MRI) for prostate cancer has increased over recent years, mainly for detection, staging, and active surveillance. However, suspicion of recurrence in the set of biochemical failure is becoming a significant reason for clinicians to request mp-MRI. Radiologists should be able to recognize the normal post-treatment MRI findings. Fibrosis and atrophic remna...
Prostate Cancer: The Role of Multiparametric Magnetic Resonance Imaging
Lopes Dias, J; Pina, J; João, R; Fialho, J; Carmo, S; Leal, C; Bilhim, T; Mateus Marques, R; Campos Pinheiro, LMultiparametric Magnetic Resonance Imaging has been increasingly used for detection, localization and staging of prostate cancer over the last years. It combines high-resolution T2 Weighted-Imaging and at least two functional techniques, which include Dynamic Contrast–Enhanced Magnetic Resonance Imaging, Diffusion-Weighted Imaging, and Magnetic Resonance Imaging Spectroscopy. Although the combined use of a pelv...
Índice Proliferativo Ki-67 no Cancro Gástrico
Nabais, C; Fradique, AC; Costa, L; Cabrita, F; Pupo, A; Quaresma, L; Silva, G; Mateus Marques, R; Esteves, J; Guedes da Silva, J; Oliveira, M; Pina, FIntrodução: O cancro gástrico representa ainda uma das principais causas de mortalidade por doença oncológica a nível mundial, apesar da evolução substancial no seu tratamento. Diversos marcadores biológicos têm sido introduzidos com intuito prognóstico da doença. A proteína Ki-67 através de técnicas imunocitoquímicas tem sido utilizada como um indicador da actividade proliferativa tumoral. No cancro gástrico o...
