A solitary pulmonary nodule (SPN) or coin lesion, [1] is a mass in the lung smaller than three centimeters in diameter. A pulmonary micronodule has a diameter of less than three millimetres. [2] There may also be multiple nodules. One or more lung nodules can be an incidental finding found in up to 0.2% of chest X-rays [3] and around 1% of CT ...
Well-demarcated, nodular lesions ranging 2–5 mm in pulmonary parenchyma. Type II pneumocytes without nuclear atypia lined thickened alveolar septa and proliferated papillary structures. Enlarged cuboidal cells lining mildly thickened alveolar septa. [11] Enlarged cuboidal cells have abundant, eosinophilic cytoplasm and large, round nuclei. [12]
Pulmonary function testing is a safe procedure; however, there is cause for concern regarding untoward reactions and the value of the test data should be weighed against potential hazards. Some complications include dizziness, shortness of breath, coughing, pneumothorax, and inducing an asthma attack. [13] [14]

Spirometry (meaning the measuring of breath) is the most common of the pulmonary function tests (PFTs). It measures lung function, specifically the amount (volume) and/or speed (flow) of air that can be inhaled and exhaled.
A defect in the perfusion images requires a mismatched ventilation defect to indicate pulmonary embolism. [8] In the ventilation phase of the test, a gaseous radionuclides such as xenon-133, krypton-81m, or technetium-99m DTPA in an aerosol form is inhaled by the patient through a mouthpiece or mask that covers the nose and mouth.
