In brief: Yes

It depends on what you are looking for. CT scans without contrast are very good at evaluating for kidney stones, evaluating lung nodules, looking at the spine and bones and looking for acute bleeding in the brain.
Contrast is better when looking at the solid organs of the abdomen, looking for infections and looking for tumors. Ask your doctor.

In brief: Depends.

For kidney stones we use no contrast, but we don't get as good a look at the solid organs.
Contrast is usually helpful, but not always necessary.
