CCP 349 Radiology

Question 1

Confirming ETT via CXR in peds

Answer 1

1. Between the thoracic inlet (clavicles) and carina
2. Between T2 to T3
3. 1 to 2cm above the carina

Question 2

describe the typical CXR for MAS

Answer 2

MAS → bilateral diffuse grossly patchy opacities. The areas of the CXR are patchy because of areas of total atelectasis, as well as areas of air trapping within the alveoli

Question 3

discuss changes to CXR that occur during pregnancy

Answer 3

1. The gravid uterus should be shielded when performing imaging studies that use ionizing radiation
2. The enlarged uterus in the 3rd trimester may prevent full inspiration when obtaining a chest X-ray
3. Uterine distention during pregnancy results in an elevation of the diaphragm that can be seen on chest X-ay.
4. A broadened cardiac silhouette and prominence of the pulmonary vasculature are also expected due to an increased blood volume and cardiac output.
5. Pulmonary edema and cephalization are abnormal findings in pregnancy.
