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.

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.

Multicenter Study Comparative Study
Minor head injury: CT-based strategies for management--a cost-effectiveness analysis.
To compare the cost-effectiveness of using selective computed tomographic (CT) strategies with that of performing CT in all patients with minor head injury (MHI). ⋯ Selecting patients with MHI for CT renders cost savings and may be cost-effective, provided the sensitivity for the identification of patients who require neurosurgery is extremely high. Uncertainty regarding long-term functional outcomes after MHI justifies the routine use of CT in all patients with these injuries.

To evaluate a technique to perform fluoroscopically directed thoracic transforaminal epidural injections. ⋯ This study evaluated an innovative technique to perform fluoroscopically directed thoracic intraforaminal nerve blocks that showed few complications and anatomically avoided transgression of structures in the posterior mediastinum.

Comparative Study
Carotid intraplaque hemorrhage imaging at 3.0-T MR imaging: comparison of the diagnostic performance of three T1-weighted sequences.
To compare the diagnostic performances of three T1-weighted 3.0-T magnetic resonance (MR) sequences at carotid intraplaque hemorrhage (IPH) imaging, with histo logic analysis as the reference standard. ⋯ The magnetization-prepared RAGE sequence, as compared with the fast spin-echo and TOF sequences, demonstrated higher diagnostic capability for the detection and quantification of IPH. Potential limitations of 3.0-T IPH MR imaging are related to hemorrhage size and coexisting calcification.
