OBJECTIVES The aim of this study was to evaluate whether an increased capsular width evidenced by ultrasound (US) could be an indirect marker of temporomandibular joint (TMJ) effusion. METHODS 138 TMJs were evaluated by US and magnetic resonance imaging (MRI) by two blinded calibrated investigators. US measures of capsular width (in mm) and MRI diagnosis(More)
AIM The aim of this study was to assess the accuracy of ultrasonography (US) in the evaluation of temporomandibular joint (TMJ) effusion compared with magnetic resonance imaging (MRI) findings, assumed as the gold standard. METHODS The study group consisted of 44 patients with signs and symptoms of temporomandibular disorders (TMD). Each joint (N=88) was(More)
Latent semantic analysis (LSA) is a tool for extracting semantic information from texts as well as a model of language learning based on the exposure to texts. We rely on LSA to represent the student model in a tutoring system. Domain examples and student productions are represented in a high-dimensional semantic space, automatically built from a(More)
Thirty-two patients with post-traumatic myelopathy were examined with a 0.5 T MRI system within 4 days of injury and the MRI findings analysed with respect to the immediate and residual functional deficit and (in 20 patients) the MRI appearances of the spinal cord in the chronic phase. In the acute phase a normal spinal cord was associated with only slight(More)
PURPOSE Anterolateral fibrous impingement of the ankle is one of the causes of post-traumatic pain in the foot. We investigated the comparative accuracy of US and MRI in this condition. MATERIAL AND METHODS Fourteen patients were submitted to arthroscopy, plain radiography, US and MRI of the foot. The patients, all sportsmen, had a clinical history of(More)
OBJECTIVE The aim of this study was to analyze the potential usefulness of MR signal intensity in differentiating malignant from benign pleural disease. SUBJECTS AND METHODS Forty-five patients with pleural lesions identified on CT scans were subsequently examined by MR imaging at 0.5 T. T1-weighted, proton density-weighted, T2-weighted, and enhanced(More)
CT and MR potentials were compared in 30 patients submitted to anterior cruciate ligament reconstruction using the patellar tendon. In each patient the clinical data were correlated with the following radiologic parameters: the course of the tibial and femoral tunnels, their intraarticular outlet sites and their shape, the shape of the intercondylar notch(More)
The CT and MR findings are reported in a case of biopsy proven rhabdomyosarcoma of the skull base. The tumor presumably originated in a pneumatized petrous ridge and had an atypical presentation of multiple cranial nerve palsy. The lesion exhibited a soft tissue density and a nonexpansile bone destruction on unenhanced CT. On MR imaging the lesion showed(More)
OBJECTIVES To test the effectiveness of a combined approach to an early diagnosis of neuro-osteoarthropathy (NOA) of the diabetic foot, we studied a group of outpatients with active NOA, presenting for the first time to our Diabetic Foot Clinic in 1998, by means of an integrated approach designed to assess bone turnover. PATIENTS AND METHODS Fifteen(More)
PURPOSE In the cranial humeral end, osteochondral injuries localize in a circular crown including part of the humeral head and part of the major and minor tuberosities. Since this region is easy to depict with US, we investigated the potentials of this technique in detecting osteochondral injuries. MATERIALS AND METHODS Seventy-five osteochondral injuries(More)
