Described below are some points on an approach to the assessment of the chest x-ray technical adequacy.Rarely, a technically inadequate chest x-ray will prohibit diagnostic interpretation but knowledge of the limitations will impact on diagnostic confidence. The CXR may be normal, especially in children, if laryngospasm (diving reflex) occurs. Increases heart size 3. On repeat exam with improved inspiration, the right heart border is normal. On the lateral view, you can look for proper penetration and inspiration by observing that the spine appears to be darken as you move caudally. Not sure where the bullet is in PA CXR. Soft tissue and bony cage Subcutaneous emphysema, fractures4.Trachea Position, Outline5. Terms and Conditions It is often quicker to assess for hyperexpansion by looking at the hemidiaphragms. The lung bases are white - Is there consolidation? A deep inspiration causes the diaphagm to move downward, resulting in elongation of the heart. Picture: 2. Normal anatomy 47. Spinous processes= Equal distance from medial clavicles. STEP 1 No imaging can help you to come to a diagnosis without the clinical information of the patient. as interstitial lung disease) Adequate exposure? Normal anatomy 15. Inspiration Assessment of inspiratory effort and lung volumes. Adequate inspiration is when: 5 – 6 anterior ribs, 9 – 10 ribs posteriorly in the mid-clavicular line, the lung apices, both costophrenic angles and the lateral rib edges are all visible : Projection: AP vs. PA film: Exposure: Left hemidiaphragm visible to the spine and vertebrae visible behind the heart: Table 5.3 – ‘RIPE’ Acronym. AP versus PA The Effect of Magnification. document.write(theYear) | Adequate inspiration? 91 terms. If the patient's inspiratory result when the film was obtained was suboptimal, then the vascular structures may appear crowded and indistinct, giving an appearance that can mimic congestive heart failure.

Near drowning. 6-7 ribs visible. CHEST X-ray. The major exception is when seeking a small pneumothorax as this will show best on full expiration. INSPIRATION. 2. The Normal CXR • Standard CXR is taken: – PA – minimal magnification of the heart – Patient standing – Full inspiration • In ill patients, the CXR is usually taken: – AP – magnifies cardiac shadow – Often supine – diaphragms higher, lung volumes lower, pathology often obscured 6. The pulsation of the hilus and the exact localization of the lesion on the projected chest or any visible pathologic pulmonary changes can be noted. It is possible to assess for hyperexpansion by counting ribs, or by checking for flattening of the hemidiaphragms. The hilus moves towards the obstructed lung during inspiration, while during expiration it moves in the other direction towards the entire lung, which crushes its air out. Look at the case below - on the first film, the loss of the right heart border silhouette would lead you to the diagnosis of a possible pneumonia. 3.
