Last month, the American Pain Society added to its recommendations to health care providers regarding the diagnosis and treatment of low back pain .
In addition, the Society decided to discuss openly procedures that could be risky to sufferers of low back pain, including recommendations on surgery and other invasive therapies.
Unfortunately, there is not a significant body of good evidence to justify unquestioningly embracing these new recommendations. It is difficult to find well-done clinical studies which support the use of a number of the more invasive treatments used for chronic low back pain.
The initial set of guidelines for the management of chronic low back pain were published in "Annals of Internal Medicine" last October. However, these recommendations dealt more with the initial evaluation of a low back pain patient, and included thoughts on what type of x-rays to order in addition to more conservative treatments such as massage/manipulation and exerci...
Abdominal ultrasound is an imaging procedure used to examine the internal organs of the abdomen, including the liver, gallbladder, spleen, pancreas, and kidneys. The blood vessels that lead to some of these organs can also be looked at with ultrasound.

How the test is performed
An ultrasound machine creates images that allow various organs in the body to be examined. The machine sends out high-frequency sound waves, which reflect off body structures to create a picture. A computer receives these reflected waves and uses them to create a picture. Unlike with x-rays or CT scans, there is no ionizing radiation exposure with this test.
You will be lying down for the procedure. A clear, water-based conducting gel is applied to the skin over the abdomen. This helps with the transmission of the sound waves. A handheld probe called a transducer is then moved over the abdomen.

Definition An abdominal MRI (magnetic resonance imaging) scan is a imaging test that uses powerful magnets and radio waves to create pictures of the inside of the belly area. It does not use radiation (x-rays). 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. Alternative Names Nuclear magnetic resonance - abdomen; NMR - abdomen; Magnetic resonance imaging - abdomen; MRI of the abdomen How the test is performed You may be asked to wear a hospital gown or clothing without metal fasteners (such as sweatpants and a t-shirt). Certain types of metal can cause blurry images. You will lie on a narrow table, which slides into a large tunnel-shaped scanner. Some exams require a special dye (contrast). The dye is usually given before the test through a vein (IV) in your hand or forearm. The dye helps the radiologist see certain areas more clearly. During the MRI, the person who operates the machine wi...
