Answer to Question 1

Peripheral nerves, meninges, cells within the brain or spinal cord

Answer to Question 2

Both are used to diagnose a pulmonary embolism. An x-ray will only visualize and thereby diagnose if the pulmonary embolism had caused a pulmonary infarct, usually seen as wedge-shaped area of increased density in the lungs. Pulmonary angiography is the gold standard for the diagnosis of PE, as it allows for the visualization of the pulmonary artery and its branches. Occlusion of an artery shows as a filling defect, and impairment in blood flow is also determined based on the flow of the contrast material.
