Comparison between STIR and T2-weighted SPAIR sequences in the evaluation of in...
Dalto,Vitor Faeda; Assad,Rodrigo Luppino; Lorenzato,Mario Müller; Crema,Michel Daoud; Louzada-Junior,Paulo; Nogueira-Barbosa,Marcello HenriqueAbstract Objective: To compare two different fat-saturated magnetic resonance imaging (MRI) techniques-STIR and T2 SPAIR-in terms of image quality, as well as in terms of their diagnostic performance in detecting sacroiliac joints (SIJ) active inflammation. Materials and Methods: We included 69 consecutive patients with suspected spondyloarthritis undergoing MRI between 2012 and 2014. The signal-to-noise ratio ...
Diagnostic performance of magnetic resonance imaging in the assessment of perio...
Sá Neto,José Luiz de; Simão,Marcelo Novelino; Crema,Michel Daoud; Engel,Edgard Eduard; Nogueira-Barbosa,Marcello HenriqueAbstract Objective: To evaluate the performance of magnetic resonance imaging (MRI) in detecting periosteal reactions and to compare MRI and conventional radiography (CR) in terms of the classification of periosteal reactions. Materials and Methods: Retrospective study of 42 consecutive patients (mean age, 22 years; 20 men) with a confirmed diagnosis of osteosarcoma or Ewing's sarcoma, MRI and CR images having ...
Diagnostic performance of 3D TSE MRI versus 2D TSE MRI of the knee at 1.5 T, wi...
Chagas-Neto,Francisco Abaeté; Nogueira-Barbosa,Marcello Henrique; Lorenzato,Mário Müller; Salim,Rodrigo; Kfuri-Junior,Maurício; Crema,Michel DaoudAbstract Objective: To compare the diagnostic performance of the three-dimensional turbo spin-echo (3D TSE) magnetic resonance imaging (MRI) technique with the performance of the standard two-dimensional turbo spin-echo (2D TSE) protocol at 1.5 T, in the detection of meniscal and ligament tears. Materials and Methods: Thirty-eight patients were imaged twice, first with a standard multiplanar 2D TSE MR technique...
Imaging assessment of glenohumeral dysplasia secondary to brachial plexus birth...
Chagas-Neto,Francisco Abaete; Dalto,Vitor Faeda; Crema,Michel Daoud; Waters,Peter M.; Gregio-Junior,Everaldo; Mazzer,NiltonAbstract Objective: To assess imaging parameters related to the morphology of the glenohumeral joint in children with unilateral brachial plexus birth palsy (BPBP), in comparison with those obtained for healthy shoulders. Materials and Methods: We conducted a retrospective search for cases of unilateral BPBP diagnosed at our facility. Only patients with a clinical diagnosis of unilateral BPBP were included, and...
THE SEVERAL FACES OF SCHMORL'S NODE: PICTORIAL ESSAY
Nogueira-Barbosa,Marcello Henrique; Crema,Michel Daoud; Herrero,Carlos Fernando Pereira da Silva; Pasqualini,Wagner; Defino,Helton Luiz AparecidoThe aim of this review is to present the imaging features of Schmorl's node (SN) occurring in conjunction with several etiologies. The SN is a relatively common finding in diagnostic spinal imaging. This condition is usually asymptomatic and its etiology is not always clear. Any disorder that weakens the subchondral bone of the vertebral body may lead to endplate disruption and consequent intravertebral disc he...
