3. Comparison to prior studies

Thoracic MR (considered separately from cardiac MR) can be useful for examination of the mediastinum, occasionally the pleura, but is generally not very useful for examination of the lungs. As no clear significant lung or mediastinal pathology is evident at chest radiography, bronchoscopy and 18FDG-PET scanning are not indicated at this point. A functional fluoroscopic, or “sniff” test”, is appropriate to evaluate for the possibility of either  weak or paralyzed left diaphragm, given the left diaphragm elevation, but, as is almost always the case, comparison to remote studies is the first priority when chest radiographic abnormalities are encountered.).

Prior chest radiography from 2008 (Figure 3) was located.

Which of the following represents the most accurate assessment of the current and prior chest radiographic findings? (click on the correct answer to be directed to the fourth of eleven pages)

1. Chest radiography shows linear and reticular abnormalities suggesting fibrosis on the prior (Figure 2) that had resolved as of the current study (Figure 1)
2. Chest radiography shows multifocal consolidation on the prior (Figure 2) that had resolved as of the current study (Figure 1)
3. Chest radiography shows multifocal pleural disease on the prior (Figure 2) that had resolved as of the current study (Figure 1)
4. Chest radiography shows nodules on the prior (Figure 2) that had resolved as of the current study (Figure 1)
5. Chest radiography shows persistent elevation of the left diaphragm on the prior (Figure 2) and the current study (Figure 1), essentially unchanged
