Question

High-resolution CT studies of the chest require a slice thickness to be reduced to?

a) 2.5 mm
b) 0.625mm
c) 1.25 mm
d) 5mm

Answer 1

High-resolution CT chest studies typically require a slice thickness of 0.625 mm to achieve greater detail in imaging.

Step-by-step explanation:

High-resolution CT (computed tomography) studies of the chest require that the slice thickness be reduced to 0.625 mm. This very fine slice thickness allows for greater detail and is particularly important for detecting small lesions and providing clear images of the lung's anatomy. Reducing the slice thickness improves the resolution of CT images, which is crucial in diagnosing various chest diseases and conditions.
