What does "ct scan w/o contrast" mean?

CT W/O CONTRAST: This is a CT scan pf the body WITHOUT the need of intravenous (IV) contrast. This does not automatically mean that the study may be done without oral contrast (typically in the setting of a CT of the abdomen and pelvis). Depends on what specifically the doctor is trying to assess.

It means: that the CT scan will be performed without the injection of intravenous contrast material.
