Accuracy of magnetic resonance imaging for diagnosing hallux valgus

Abstract Objective: To assess the accuracy of magnetic resonance imaging (MRI) for the diagnosis of hallux valgus using radiography during weight bearing as the gold standard. Materials and Methods: This was a retrospective analysis of all patients undergoing MRI of the foot and radiography of the foot during weight bearing at our institution between January and June of 2015. The hallux valgus angle (HVA) was m...

Fighting the invisible enemy: providing support and structure to radiology resi...

Abstract The objective of this article is to share the strategy we used in order to restructure the radiology and diagnostic imaging department of a referral institution during the coronavirus disease 2019 pandemic, on the basis of the current recommendations. It is essential to integrate the work of supervisors, preceptors, and residents, maintaining communication and sharing decisions, with mutual support, as...

Is possible to rule out clinically significant prostate cancer using PI-RADS v2...

ABSTRACT Objectives To evaluate the diagnostic performance and interobserver agreement of PI-RADS v2. Materials and Methods In this Institutional Review Board approved single-center retrospective study, 98 patients with clinically suspected PCa who underwent 3-T multiparametric MRI followed by MRI/TRUS fusion-guided prostate biopsy were included from June 2013 to February 2015. Two radiologists (R1 and R2) with...

Positron emission tomography/magnetic resonance imaging (PET/MRI): An update an...

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-compatible silicon photomultipliers of PET, permitted an increase in the diagnostic performance of PET/MRI transl...

Paracoccidioidomycosis in a liver transplant recipient

ABSTRACT Paracoccidioidomycosis is a granulomatous systemic mycosis that is endemic in Latin America; it is an extremely rare infection following solid organ transplantation. In this study, we describe the first report of disseminated paracoccidioidomycosis in a 3-year-old girl who underwent liver transplantation 2 years previously. The radiologic diagnosis and patient follow-up are described. In addition, we r...

Cancer care network: Structure analysis of enabled services

Summary Introduction: Cancer has now become part of the agenda of health managers, prompting them to consider new models of system organization. Objective: To study the cancer care network of the Brazilian public health system (SUS, in the Portuguese acronym) in the state of São Paulo by analyzing the structure of the installed and enabled network for treatment and its characteristics. Method: A single, integra...

Hepatocyte-specific contrast agent-enhanced magnetic resonance cholangiography:...

Abstract A large number of gadolinium chelates have recently been tested in clinical trials. Some of those have already been approved for clinical use in the United States and Europe. Thus, new diagnostic perspectives have been incorporated into magnetic resonance imaging studies. Among such gadolinium chelates are hepatobiliary-specific contrast agents (HSCAs), which, due to their property of being selectively...
