Correct!
1. Enhanced chest CT
Contrast-enhanced chest MRI could be performed but probably would not provide any benefit over the more commonly chosen cross sectional evaluation method for chest disease- enhanced chest CT; the latter also provides more optimal assessment of the lung parenchyma than MR. 18FDG – PET scan could be of benefit, but regardless of whether tracer activity in the pleural space is present or not, the nature of the pleural effusion should first be assessed with dedicated anatomic imaging. Pulmonary function testing may provide useful information at some point, but the current information suggests that investigation should be directed towards defining the nature of the right pleural space abnormality.
The patient underwent enhanced chest CT (Figure 2).
