Real-time vs static scoring in musculoskeletal ultrasonography in patients with inflammatory hand osteoarthritis.

Objectives: Agreement between real-time and static ultrasonography has not been studied in musculoskeletal diseases. We studied this agreement in inflammatory hand OA.

Methods: Ultrasonography was performed blinded to clinical information of 30 joints of 75 patients with hand OA, treated with prednisolone in a randomized placebo-controlled double-blind trial.

A prospective study on MRI findings and prognostic factors in athletes with MTSS.

In medial tibial stress syndrome (MTSS) bone marrow and periosteal edema of the tibia on the magnetic resonance imaging (MRI) is frequently reported. The relationship between these MRI findings and recovery has not been previously studied. This prospective study describes MRI findings of 52 athletes with MTSS.

CT and MR assessment of tumors of the nose and paranasal sinuses, the nasopharynx and the parapharyngeal space using ROC methodology.

Neoplastic disease of the nose and paranasal sinuses, the nasopharynx and the parapharyngeal space requires thorough assessment of location and extension in order to plan appropriate treatment. This study evaluates computer tomography and magnetic resonance imaging in the workup of malignant and non-malignant tumors of the nose and paranasal sinuses, the nasopharynx and the parapharyngeal space in 76 patients. An attempt is made to characterize histopathology on magnetic resonance images by analyzing the signal intensities on T1- and T2-weighted images relative to muscle and brain tissue.

Neurocutaneous melanosis associated with intraspinal lipoma.

A case of neurocutaneous melanosis developing a leptomeningeal melanoma is described in a ten year old girl in whom an intraspinal lipoma had been resected seven years earlier. Standard and CT myelographic findings are described and the complementary role of Gadolinium-enhanced MRI is discussed. The literature is reviewed and the association of a lipoma and neurocutaneous melanosis has not been encountered.

Imaging of brain metastases. Comparison of computerized tomography (CT) and magnetic resonance imaging (MRI).

For the demonstration of brain metastases both CT and MRI are available as diagnostic modalities. To compare both imaging methods as to their sensitivity in detecting brain metastases CT scans and MR images of 60 patients with suspected brain metastases were evaluated. Comparing contrast-enhanced CT and plain MRI neither modality was found to be clearly superior in this respect.
