Accepting the importance of accurate collimation to the area of interest as a method of reducing dose is further emphasised in the European Guidelines on Quality Criteria for Diagnostic Radiographic Images in Paediatrics5. These guidelines state that the maximum field size tolerance should be less than 2 cm greater than the area of interest and this is further reduced to a tolerance of 1 cm in neonates. Consequently, appropriate quality assurance testing of mobile and stationary radiographic equipment to ensure that the light beam diaphragm correlates with the radiation beam is vital if consistent and accurate collimation is to be achieved.
This number increases to nearly 300 million alveoli by the age of 8 years4, but after this age the alveoli grow in size rather than number. From this information it can be deduced that a relatively minor respiratory pathology in an 8-year-old child can cause severe respiratory distress in an infant and therefore radiographers should be aware of the varied appearances and clinical presentations of common respiratory disorders. g. the bifurcation of the trachea, which is seen at the level of the fifth/sixth thoracic vertebra in an adult, lies opposite the third thoracic vertebra in an infant and descends to the level of the fourth thoracic vertebra by approximately 8 years of age).
Plain film radiography of the chest will display increased radioopacification of the deflated lung, evidence of the lung edge medial to the wall of the thorax and increased radiolucency lateral to the lung. Treatment is typically by insertion of a chest drain to remove the air from the pleural space and allow the lung to re-inflate. A small pneumothorax will generally resolve without medical intervention. A tension pneumothorax (Fig. 16) is an acute surgical emergency and usually occurs as a result of traumatic injury to the chest wall.
