Sets with similar termsTerms in this set (75)Which of the following technical factors is recommended for an adult chest radiography? Sets with similar termsHow many posterior ribs should be visualized above the diaphragm in order for a PA chest to be evaluated for adequate inspiration?Ten posterior ribs are visible above the diaphragm. There is a sharp outline of the heart and diaphragm. A faint shadow of the ribs and superior thoracic vertebrae is visible through the heart shadow. Lung markings are visible from the hilum to the periphery of the lung.
How many ribs should be visible above the diaphragm on a PA chest?Position of part The top of the lungs should be visible. The exposure should be made at full inspiration and should show rib 10 posteriorly above the diaphragm and rib 6 anteriorly.
How many ribs is good for inspiratory effort?Assessment of inspiratory effort and lung volumes. Ideally 7-9 ribs should be visible. Less than 7 suggests poor effort by the patient and/or low lung volumes as in restrictive lung disease, atelectasis, etc. 10 or more ribs typically suggests hyperinflation as in COPD, asthma, bronchiectasis.
At what level should the central ray be centered for anteroposterior ribs above the diaphragm?The central ray (CR) for an anteroposterior (AP) supine, adult chest projection, should be centered: 3 to 4 inches (8 to 10 cm) below the jugular notch.
