Chest pain evaluation in the emergency department: can MDCT provide a comprehensive evaluation?
The purpose of our study was to determine whether MDCT can provide a comprehensive assessment of cardiac and noncardiac causes of chest pain in stable emergency department patients. ⋯ ECG-gated MDCT appears to be logistically feasible and shows promise as a comprehensive method for evaluating cardiac and noncardiac chest pain in stable emergency department patients. Further hardware and software improvements will be necessary for adoption of this paradigm in clinical practice.

16-MDCT of the posttraumatic pediatric elbow: optimum parameters and associated radiation dose.
Our objective was to investigate a low-radiation-dose protocol for 16-MDCT of the posttraumatic pediatric elbow using z-axis automatic tube-current modulation, based on optimum scanning parameters determined in a porcine fracture model, and to report the radiation dose from this technique in nine children with acute elbow trauma. ⋯ For the posttraumatic pediatric elbow, 16-MDCT using z-axis automatic tube-current modulation was optimal at 100 kVp with a noise index of 20 and a minimum amperage of 25 mA.

Endobronchial actinomycosis associated with broncholithiasis: CT findings for nine patients.
Our objective was to assess the CT findings for endobronchial actinomycosis associated with broncholithiasis. ⋯ Endobronchial actinomycosis associated with broncholithiasis manifests as a proximal obstructive calcified endobronchial nodule associated with distal post-obstructive pneumonia of the involved lobe or segment on CT. The possibility of endobronchial actinomycosis should be entertained when broncholithiasis is seen on CT in tuberculosis-endemic areas.
