An abdominal aortic aneurysm is when a weakened part of the aorta - the largest blood vessel in the human body - begins to bulge in the abdomen. If untreated, the vessel could burst, causing severe internal bleeding. Blood clots could also form inside the aneurysm, and then travel to the lower extremeties and restrict blood flow, causing severe pain, and if left untreated, could result in amputation.

Symptoms of AAA include:

• a throbbing sensation in the abdomen, similar to a heartbeat
• Sudden sharp pain in the abdomen and lower back
• discoloration of the toes and feet, as well as sores

Crystal Imaging uses abdominal ultrasounds to detect AAA. If a problem is detected, one should seek medical attention immediately.

One the day of the screening, participants should:

• Wear a comfortable two-piece outfit consisting of loose clothing.
• Fast for 4 hours prior to your screening.
• Make sure the meal you eat 4 hours prior to your screening is a light one (less than 1/2 of what you normally eat of non-gassy food).
• If you are thirsty during your fasting period, you may have 1/2 cup of coffee or tea and a moderate amount of water.
• If you take medication, take it as prescribed.
• If you are diabetic and are not comfortable fasting for 4 hours, please limit yourself to a "diabetic meal" (piece of toast, 1 cup of any kind of juice and 1/2 cup coffee or tea). If you are in doubt, please follow your diabetic care plan.
