Prospective Evaluation of Next Generation CT Reconstruction
Background:
- Computed Tomography (CT) is a scan that makes detailed pictures of the body. It uses
radiation to do that. In 2011, about 85.3 million CT scans were done in the United States.
But there is growing concern about the health effects of radiation. There are new and
different ways to make CT pictures that use less radiation. Researchers want to learn whether
these new methods create images that are similar to images from a traditional CT.
Objective:
- To learn if new CT imaging methods with less radiation make images that are similar to
traditional ways.
Eligibility:
- Adults 18 years of age and older who are scheduled for a CT of the chest, abdomen and
pelvis with contrast.
Design:
- Researchers will review participants medical records to see if they can be in this
study.
- Participants may have blood drawn from an arm vein by a needle stick. The blood will be
used to make sure they can be in this study and that it is safe for them to have
contrast.
- During the participants CT scan appointment, one extra scan will be done using low
radiation methods.
- During a CT scan, the participant lies on a table. A large x-ray machine takes pictures
of the body.

Computed Tomography uses ionizing radiation to make pictures of the body. Different methods
of creating CT pictures have been developed that allow reductions in the amount of radiation.
The purpose of this research study is to learn whether these new imaging methods using less
radiation to create images are similar to the traditional and current method.
