Definition A magnetic resonance imaging (MRI) scan of the chest is a noninvasive imaging method that uses powerful magnets and radio waves to create detailed pictures of the chest (thoracic) area. Unlike x-rays and computed tomographic ( CT ) scans, which use radiation, MRI uses powerful magnets and radio waves. The MRI scanner contains the magnet. The magnetic field produced by an MRI is about 10 thousand times greater than the Earth's. The magnetic field forces hydrogen atoms in the body to line up in a certain way (similar to how the needle on a compass moves when you hold it near a magnet). When radio waves are sent toward the lined-up hydrogen atoms, they bounce back, and a computer records the signal. Different types of tissues send back different signals. Single MRI images are called slices. The images can be stored on a computer or printed on film. One exam produces dozens or sometimes hundreds of images.

The gallbladder is a pear-shaped pouch that sits just under the liver. It's main function is to store the bile made by the liver. The gallbladder then releases bile into the intestines as needed to digests fats. The more fat in the meal, the more the gallbladder works. Most "gallbladder diets" aim to reduce the workload on the gallbladder. They remove foods that could cause gallstones and reduce painful symptoms caused by gallbladder disease. As you can imagine, reducing high-fat foods is one of the main tenants of a diet to deal with gallbladder disease. The following foods should be avoided on the gallbladder diet:
Fried or greasy foods
Whole-fat dairy and whole milk
Processed ("junk") foods
Healthy foods for gallbladder issues include:
Whole foods, fruits and vegetables
Lean, low-fat meats
Low-fat dairy and low-fat or skim milk
*Some research also indicates that moderate alcohol, drinking (caffeinated) coffee and eating...
