Placental magnetic resonance imaging: normal appearance, anatomical variations,...
Novis,Maria Inês; Moura,Ana Paula Carvalhal; Watanabe,Agnes de Paula Fernandes; Pereira,Luciana Carla Longo e; Warmbrand,Gisele; D'Ippolito,GiuseppeAbstract Placental magnetic resonance imaging (MRI) has been increasingly requested, especially for the evaluation of suspected cases of placental adhesive disorders, generally known as placenta accreta. Abdominal radiologists need to become familiar with normal placental anatomy, anatomical variations, the current terminology, and major placental diseases that, although rare, are important causes of maternal a...
Proposal for a structured computed tomography report in the evaluation of pancr...
Lopes,Paulo Gustavo Maciel; Matsumoto,Carlos Alberto; Lobo,Edson José; D'Ippolito,GiuseppeAbstract Objective: To create a structured computed tomography (CT) report for the systematic evaluation of pancreatic ductal adenocarcinoma (PDAC), based on the opinions of clinicians and surgeons. Materials and Methods: This was a prospective study in which we applied a 21-item questionnaire to experts in pancreatic diseases in order to create a model of a structured abdominal CT report. The questionnaire add...
Using computed tomography enterography to evaluate patients with Crohn's diseas...
Burlin,Stênio; Favaro,Larissa Rossini; Bretas,Elisa Almeida Sathler; Taniguchi,Lincoln Seiji; Loch,Ana Paula; Argollo,Marjorie CostaAbstract Objective: To assess the impact that examiner experience has on the reproducibility and accuracy of computed tomography (CT) enterography in the detection of radiological signs in patients with Crohn's disease. Materials and Methods: This was a retrospective, cross-sectional observational study involving the analysis of CT enterography scans of 20 patients with Crohn's disease. The exams were analyzed ...
Mapping the different methods adopted for diagnostic imaging instruction at med...
Chojniak,Rubens; Carneiro,Dominique Piacenti; Moterani,Gustavo Simonetto Peres; Duarte,Ivone da Silva; Bitencourt,Almir Galvão VieiraAbstract Objective: To map the different methods for diagnostic imaging instruction at medical schools in Brazil. Materials and Methods: In this cross-sectional study, a questionnaire was sent to each of the coordinators of 178 Brazilian medical schools. The following characteristics were assessed: teaching model; total course hours; infrastructure; numbers of students and professionals involved; themes address...
What radiologists should know about tomographic evaluation of acute diverticuli...
Naves,Aline de Araújo; D'Ippolito,Giuseppe; Souza,Luis Ronan Marquez Ferreira; Borges,Sílvia Portela; Fernandes,Glênio MoraesAbstract Acute diverticulitis of the colon is a common indication for computed tomography, and its diagnosis and complications are essential to determining the proper treatment and establishing the prognosis. The adaptation of the surgical classification for computed tomography has allowed the extent of intestinal inflammation to be established, the computed tomography findings correlating with the indication f...
Abdominal vascular syndromes: characteristic imaging findings
Cardarelli-Leite,Leandro; Velloni,Fernanda Garozzo; Salvadori,Priscila Silveira; Lemos,Marcelo Delboni; D'Ippolito,GiuseppeAbstract Abdominal vascular syndromes are rare diseases. Although such syndromes vary widely in terms of symptoms and etiologies, certain imaging findings are characteristic. Depending on their etiology, they can be categorized as congenital-including blue rubber bleb nevus syndrome, Klippel-Trenaunay syndrome, and hereditary hemorrhagic telangiectasia (Rendu-Osler-Weber syndrome)-or compressive-including "nutc...
Value of renal cortical thickness as a predictor of renal function impairment i...
Yamashita,Samia Rafael; Atzingen,Augusto Castelli von; Iared,Wagner; Bezerra,Alexandre Sérgio de Araújo; Ammirati,Adriano LuizObjective: To determine the presence of linear relationship between renal cortical thickness, bipolar length, and parenchymal thickness in chronic kidney disease patients presenting with different estimated glomerular filtration rates (GFRs) and to assess the reproducibility of these measurements using ultrasonography. Materials and Methods: Ultrasonography was performed in 54 chronic renal failure patients. Th...
The role of gadoxetic acid as a paramagnetic contrast medium in the characteriz...
Bormann,Renata Lilian; Rocha,Eduardo Lima da; Kierzenbaum,Marcelo Longo; Pedrassa,Bruno Cheregati; Torres,Lucas Rios; D'Ippolito,GiuseppeRecent studies have demonstrated that the use of paramagnetic hepatobiliary contrast agents in the acquisition of magnetic resonance images remarkably improves the detection and differentiation of focal liver lesions, as compared with extracellular contrast agents. Paramagnetic hepatobiliary contrast agents initially show the perfusion of the lesions, as do extracellular agents, but delayed contrast-enhanced im...
Readjustment of abdominal computed tomography protocols in a university hospita...
Romano,Ricardo Francisco Tavares; Salvadori,Priscila Silveira; Torres,Lucas Rios; Bretas,Elisa Almeida Sathler; Bekhor,Daniel; Caldana,Rogério PedreschiAbstractObjective:To assess the reduction of estimated radiation dose in abdominal computed tomography following the implementation of new scan protocols on the basis of clinical suspicion and of adjusted images acquisition parameters.Materials and Methods:Retrospective and prospective review of reports on radiation dose from abdominal CT scans performed three months before (group A – 551 studies) and three mon...
Spontaneous rupture of ovarian cystadenocarcinoma: pre- and post-rupture comput...
Salvadori,Priscila Silveira; Bomfim,Lucas Novais; von Atzingen,Augusto Castelli; D'Ippolito,GiuseppeAbstractEpithelial ovarian tumors are the most common malignant ovarian neoplasms and, in most cases, eventual rupture of such tumors is associated with a surgical procedure. The authors report the case of a 54-year-old woman who presented with spontaneous rupture of ovarian cystadenocarcinoma documented by computed tomography, both before and after the event. In such cases, a post-rupture staging tends to be l...
