Question

if you suspect a chest mass on x - ray, what follow up imaging modality would you recommend?
ultrasound
chest ct
chest mri
oblique chest x - rays

Explanation:

Chest CT (Computed Tomography) provides detailed cross - sectional images of the chest, which is highly effective in evaluating suspected chest masses. Ultrasound has limited use in chest mass evaluation due to poor penetration through air - filled lungs. Chest MRI is not the first - line follow - up as it is more expensive and has longer acquisition times compared to CT. Oblique chest x - rays do not provide the detailed anatomical information that CT does for characterizing a mass.

Answer:

Chest CT
