If you are measuring doses from vials, do not reuse needles and syringes. If you are using the cartridges or pens, use a new needle each time. Learn how to discard needles and medical supplies safely. Consult your pharmacist for more information.
1 Pulmonary nodules appear in about one of every 200 chest X-rays and most chest CT scans. 2  At least 60% of pulmonary nodules seen on chest X-rays turn out to be benign, and 99% of those on chest CT are benign. 3  Pulmonary nodules are much more commonly found than are lung cancers or benign lung tumors. A way to tell the difference between a benign and malignant lung nodule is to chart the rate of growth of the nodule. 2  Benign nodules will grow very slowly, if at all, while cancerous nodules on average can double in size every four months or less.
A solitary pulmonary nodule is not an uncommon finding on a chest x-ray. A solitary pulmonary nodule can result from a wide range of causes. Most nodules are benign but some can be malignant. The CT image above shows a right lower lobe centrally calcified nodule, consistent with a benign granuloma.
