										Radiograph ClassificationSubset 3Radiograph #33
Answer Key #33
Note that large opacities may occur in the middle and lower lung zones. The obligatory symbol for a rib fracture (**fr**, posterolateral right ninth) should be checked for this image. Concern for malignancy was raised regarding the large opacity on the right and **ca** was checked in 4B. The worker’s personal physician should therefore be notified. Sternal wires should be mentioned in 4C.
Radiograph #34
Answer Key #34 (Updated 9/28/2023)
In this example, chest wall pleural plaque (in profile and face on) is recognized mainly by the presence of calcium; the soft-tissue shadow of the plaque is less apparent. In this circumstance, plaque is presumed to be present and both the site and calcification must be recorded in Section 3B. Note: small pneumoconiotic opacities are simulated on the right by nodular pleural calcification, and the rolled-edge appearance of a calcified face-on plaque is illustrated in the left middle lung zone. (see comments on Radiograph # 21 for additional findings.)
Radiograph #35
Answer Key #35 (Updated 9/28/2023)
Radiograph #35 presents multiple pleural findings.RADIOGRAPHS #31 AND #32Page 3 of 4RADIOGRAPHS #36, #37 AND #38
