Low contrast is defined by:

Explanation:
In radiography, contrast depends on how many gray tones the image shows. Low contrast means there are many subtle differences between tissue densities, so the image displays a broad range of brightness levels with lots of midtones. This is described as a long gray-scale with many shades of gray, which makes distinguishing similar tissues harder because the transitions between them are gradual. The other descriptions don’t fit: a short gray-scale implies few brightness levels and high contrast; short-gray-scale with many shades or long-gray-scale with few shades mix incompatible terms and don’t reflect the broad range of tones characterizing low contrast.
