Increasing tissue contrast for bone assessment on magnetic resonance imaging has been the aim of several recent studies, and various techniques have proposed that purpose, including ultrashort echo time sequences, zero gradient sequences in acquisition forms. In this article, we discuss fast field resembling a computed tomography using restricted echo-spacing (FRACTURE) sequence, which started to use routinely our practice. The FRACTURE are based with different times specific postprocessing....
Resumo Aumentar o contraste tecidual nas imagens obtidas com a ressonância magnética para avaliação óssea tem sido objetivo de vários estudos recentes e diversas técnicas têm propostas este fim, incluindo sequências tempo eco ultracurto, zero, além gradiente, em variadas formas aquisição. Neste artigo trazemos uso da sequência FRACTURE (acrônimo do inglês fast field echo resembling CT using restricted spacing), que passamos utilizar rotineiramente no nosso serviço. Esta técnica se baseia na...
Purpose To evaluate the diagnostic performance of free breathing three‐dimensional gradient echo‐sequence with radial data sampling (radial 3D‐GRE) in MR imaging normal and diseased pancreas, using standard 3D‐GRE for comparison cooperative patients, to perform a preliminary assessment noncooperative patients. Materials Methods One hundred eight consecutive patients underwent 1.5 Tesla abdomen that included pre‐ postcontrast 3D‐GRE. The sequences were evaluated by two radiologists...
Abstract Purpose: To evaluate the relative enhancement of liver, pancreas, focal nodular hyperplasia (FNH), pancreas‐to‐liver index, and FNH‐to‐liver index in hepatic arterial dominant phase (HADP) after injection hepatocyte‐specific MRI contrast agents, gadoxetic acid gadobenate dimeglumine, on 3 1.5 Tesla (T) same patient. Materials Methods: The database was retrospectively searched to identify consecutive patients who underwent abdominal at 3T 1.5T systems, using both 0.025 mmol/kg...
The aims of this study were to evaluate the intra- and interobserver reproducibility manual segmentation bone sarcomas in magnetic resonance imaging (MRI) studies compare semiautomatic methods. This retrospective included twelve osteosarcoma eight Ewing sarcoma MRI performed prior any therapeutic intervention. All cases histopathologically confirmed. Three radiologists used 3D-Slicer software perform a blinded independent manner. One radiologist segmented manually also with GrowCut tool....
To evaluate the degree of similarity between manual and semiautomatic segmentation soft-tissue sarcomas on magnetic resonance imaging (MRI).This was a retrospective study 15 MRI examinations patients with histopathologically confirmed acquired before therapeutic intervention. Manual segmentations were performed by three radiologists, working independently, using software 3D Slicer. The Dice coefficient (DSC) Hausdorff distance calculated in order to segmentation. compare two modalities terms...
To describe magnetic resonance imaging (MRI) findings in musculoskeletal paracoccidioidomycosis (PCM).Retrospective case series study after IRB approval. Two radiologists reviewed consensus the MRI of 11 patients with microbiologically and/or pathologically proven osteoarticular PCM. The evaluation included discrimination abnormalities joints, bones and soft tissues.Mean age was 29 years (10-55 years), eight men three women. Musculoskeletal involvement only or primary presentation disease...
To compare enhancement of the liver and pancreas quantitatively on late hepatic arterial phase images among various gadolinium-based contrast agents (GBCAs) at 1.5 Tesla (T) MRI.Patients underwent consecutive MR studies with following GBCAs: gadopentetate dimeglumine (0.1 mmol/kg) gadobenate (0.05 mmol/kg), gadoxetic acid, gadobutrol group. The was evaluated phase. Relative pancreas-to-liver ratio also calculated.Mean % 21.57 55.40, mean relative to 2.23. Mean for gadopentetate, gadobenate,...
OBJECTIVE: To evaluate a comprehensive MRI protocol that investigates for cancer, vascular disease, and degenerative/inflammatory disease from the head to pelvis in less than 40 minutes on new generation 48-channel 3T system. MATERIALS AND METHODS: All MR studies were performed scanner. A 20-channel head/neck coil, two 18-channel body arrays, 32-channel spine array employed. total of 4 healthy individuals studied. The designed included combination single-shot T2-weighted sequences,...
To evaluate the anatomical variations of attachment inferior glenohumeral ligament (IGHL) to anterior glenoid rim.This was a retrospective review 93 magnetic resonance arthrography examinations shoulder. Two radiologists, who were blinded patient data and working independently, read examinations. Interobserver intraobserver agreement evaluated. The pattern IGHL its position on rim recorded.In 50 (53.8%), classified as type I (originating from labrum), whereas it II neck) in 43 (46.2%)....
