To test the hypothesis that T2 signals in lesions and normal-appearing tissue are sufficiently similar that signal variations represent true variations in metabolite concentration. ⋯ For the purpose of metabolic quantification at 3.0 T and echo times of less than 100 msec, an average T2 value per metabolite should suffice for any brain region and lesion regardless of disease duration, age, or disability in any RR MS patient and their controls.

To document the spectrum of misleading thin-section computed tomographic (CT) diagnoses in patients with biopsy-proved idiopathic pulmonary fibrosis (IPF). ⋯ In the correct clinical setting, a diagnosis of IPF is not excluded by thin-section CT appearances more suggestive of NSIP, chronic HP, or sarcoidosis. (c) RSNA, 2010.

To evaluate intra- and interobserver agreement for the interpretation of lumbar 1.5-T magnetic resonance (MR) images in a community setting. ⋯ http://radiology.rsna.org/lookup/suppl/doi:10.1148/radiol.09090706/-/DC1.

To prospectively evaluate the potential value of fluorocholine (FCH) positron emission tomography (PET)/computed tomography (CT) in the preoperative staging of patients with prostate cancer who had intermediate or high risk of extracapsular disease. ⋯ http://radiology.rsna.org/lookup/suppl/doi:10.1148/radiol.09090413/-/DC1.

To evaluate the feasibility, efficacy, and safety of percutaneous vertebroplasty (PV) in the treatment of pathologic fractures owing to malignancy with epidural involvement, with or without neurologic symptoms of spinal cord or cauda equina compression. ⋯ The feasibility, efficacy, and safety of PV were confirmed in patients experiencing pain related to malignant spinal tumors with epidural extension, with a low complication rate. PV should become part of the palliative analgesic treatment for such patients. (c) RSNA, 2010.
