We wish to report an unusual cause of chest pain and hemoptysis. A 62-year-old woman presented with persistent cough and mild substernal chest discomfort. She had previously noted one episode of blood-tinged sputum. Physical examination was completely normal. Initial laboratory data included a normal CBC, chest x-ray film, and sputum analysis. Bronchoscopy revealed the anterior midtrachea to be...
Existing vertebral fractures are often missed because they are clinically difficult to diagnose, because recognition of the fractures on radiological images is difficult or because the clinical relevance of the diagnosis of vertebral fractures may be underestimated by the treating physician. There is every reason to focus on the diagnosis and treatment of vertebral fractures: they are strong pr...

It is documented that well-modeled Monte Carlo dose calculation algorithms are more accurate than traditional correction-based algorithms or convolution algorithms at predicting dose distributions delivered to heterogeneous volumes. This increased accuracy has clinical implications for CyberKnife, particularly when comparing dose distributions between the ray-tracing and Monte Carlo algorithms....
