About

The purpose of this study is to use the Squid magnetometer (Superconducting QUantum Interference Device) to help diagnose electrical and mechanical abnormalities of the stomach and intestines.

Full description

The Squid magnetometer is a non-invasive investigational device that measures the electrical activity in the smooth muscle of the intestines. Volunteers with normal bowel activity, those with gastric problems, and diabetics with gastric problems will be studied under the SQuid to determine normal and abnormal activity. Diabetics with an abnormal gastric emptying study will be asked to participate.

Enrollment: 78 patients

Sex: All

Ages: 14 to 65 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Normal volunteers, those with stomach problems, and Diabetics with abnormal gastric emptying study

Exclusion criteria

• Diabetics with a normal gastric emptying study
• Participants with claustrophobia

Trial design

78 participants in 2 patient groups

poor blood flow

Description:

Group with partial ischemia to the small intestine

Good blood flow

Description:

Group with normal blood flow, given different conditions to effect electrical currents in normal smooth muscle
