Additive Pathologies v Destructive Pathologies S 50 Additive

Additive Pathologies v. Destructive Pathologies S 50 ➔ Additive pathologies increase absorption characteristics, making the part more difficult to penetrate, requiring an increase in radiographic technique. kj Additive and destructive conditions that result in change of normal bony structures, soft tissue, air or fluid content of the patient require technical adjustments to compensate for the exposure change. Bronchiectasis is a irreversible dilation of bronchi or bronchioles that may result from repeated multiple pulmonary infections or obstructions. -Results in increased production of mucus collecting in dilated regions which appear radiodense with less air in pus-filled regions Paget’s Disease (osteitis deformans) is a non-neoplastic bone disease that disrupts new bone growth; resulting in over production of very dense yet soft bone. -Appears as mixed areas of sclerotic and cortical thickening, resulting in cotton wool appearance Osteochondroma (exostosis) is a benign, neoplastic bone lesion that is caused by consolidated overproduction of bone at a joint -Tumor grows parallel to the bone ➔ Destructive pathologies decrease absorption characteristics, making the part less difficult to penetrate, requiring a decrease in radiographic technique. Pneumothorax is an accumulation of air in the pleural space that may result in partial or complete collapse of the lung -Lung displaced from chest wall, no lung markings Emphysema is an chronic lung disease in which air spaces in the alveoli become enlarged as a result of alveolar wall destruction and loss of elasticity. -Increased lung dimensions, barrel chest, flattened diaphragm, radiolucent lungs Multiple Myeloma is the most common type of primary cancerous bone tumor that arises from bone marrow or marrow cells. - Multiple punched out osteolytic regions throughout affected bone
