Question

Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A) : In a lateral thoracic radiograph, solid lesions in the dependent lung may not be visualized.
Reason (R) : The non-dependent lung suffers atelectasis, and hides the lesion beneath it.
In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A).
• B. Both (A) and (R) are correct but (R) is NOT the correct explanation of (A).
• C. (A) is correct but (R) is not correct.
• D. (A) is not correct but (R) is correct.

Hint:

To ensure complete evaluation of both lung fields:
Always take three radiographic views (Right Lateral, Left Lateral, and Ventrodorsal/Dorsoventral).
A lesion in the left lung is best seen in a right lateral view because the left lung is non-dependent (well-aerated) in that position.

Answer 1

The Correct Option is C
