OBJECTIVE The objective of our study was to evaluate the performance of MRI for the diagnosis of adhesive capsulitis using signal intensity changes of the inferior glenohumeral ligament on T2-weighted fat-saturated sequences. MATERIALS AND METHODS MR images of 34 shoulders with a final clinical diagnosis of adhesive capsulitis were compared with those of(More)
PURPOSE To compare the dose and image quality of a standard dose abdominal and pelvic CT with Filtered Back Projection (FBP) to low-dose CT with Adaptive Iterative Dose Reduction 3D (AIDR 3D). MATERIALS AND METHODS We retrospectively examined the images of 21 patients in the portal phase of an abdominal and pelvic CT scan before and after implementation(More)
Bone marrow edema is easily identified on MRI. The terminology suggests that the water content of bone marrow is increased when it is T1W hypointense and T2W hyperintense. It is a misnomer since, histologically, the abnormality does not correspond to marrow edema. The histological findings vary based on the underlying etiology and the presence of fibrosis(More)
OBJECTIVE The purpose of our study was to define the diagnostic value of tomosynthesis compared with standard radiography and CT in wrist injuries. MATERIALS AND METHODS One hundred consecutive patients with acute wrist trauma were investigated with standard radiography, tomosynthesis, and CT. Reference results were those obtained with CT; follow-up(More)
OBJECTIVE To evaluate the relationship between multiple MR perfusion parameters and symptoms of patients with osteoid osteomas after percutaneous laser therapy. METHODS MR perfusion studies of 20 patients diagnosed with an osteoid osteoma, treated with CT-guided percutaneous laser therapy, were retrospectively evaluated. Multiple perfusion parameters(More)
With an improvement in the temporal and spatial resolution, computed tomography (CT) is indicated in the evaluation of a great many osteoarticular diseases. New exploration techniques such as the dynamic CT and CT bone perfusion also provide new indications. However, CT is still an irradiating imaging technique and dose optimisation and reduction remains(More)
PURPOSE To compare the enhancement dynamics of osteoid osteomas with other benign and malignant lytic bone lesions using CT perfusion. PATIENTS AND METHODS CT perfusion parameters of 15 patients with a final diagnosis of osteoid osteoma, 15 patients with lesions that mimic osteoid osteomas and 26 patients with other bone lytic lesions were compared.

A progressive increase in the detector width in CT scanners has meant that advanced techniques such as dynamic, perfusion and dual-energy CT are now at the radiologist's disposal. Although these techniques may be important for the diagnosis of various musculoskeletal diseases, data acquisition and interpretation can be challenging. This article offers a(More)
OBJECTIVE To describe the association between linear T2 signal abnormalities in the subchondral bone and structural knee lesions. MATERIALS AND METHODS MR studies of patients referred for the evaluation of knee pain were retrospectively evaluated and 133 of these patients presented bone marrow edema pattern (BMEP) (study group) and while 61 did not(More)
Neuropathies of the shoulder are considered to be entrapment syndromes. They are relatively common, accounting for about 2% of cases of sport-related shoulder pain. Many instances involve suprascapular neuropathy, but the clinical diagnosis is often delayed because of nonspecific symptoms. Classically, EMG is the gold standard investigation but MRI(More)
