Why Is Ultrasound Safer Than X Rays
An ultraound, also known as a sonogram, is a painless and relatively inexpensive imaging test that utilizes sound waves instead of ionizing radiation. There are no side effects. Ultrasound can give us two-dimensional, and in some applications three-dimensional, images of structures and organs in virtually any part of the body. In addition to diagnostic uses, such as evaluating abnormalities in the abdomen, pelvis, and breast, ultrasounds are commonly used to guide needle and catheter placement in a variety of surgical ...Read more
20yo. Calf pain. Ultrasound normal, blood work normal. Went to ER, SOB, CT w/dye normal, X-ray normal, EKG normal. Anxiety? Flying in the AM safe?
I think it is safe.: Apparently they looked for blood clot in your legs and lungs and did not find any. It could be anxiety or myalgia or something similar to it. If otherwise you are a healthy person then there is no reason for not flying. During flying I would suggest streching your legs by moving around whenever you get an opportunity as a preventive measure for the DVT. ...Read more
The gallbladder contracts in response to certain stimuli, most physiologic is the presence of food (fat) in the stomach/small intestine. However ultrasound, looking for stones, is best done when the gallbladder is full, of bile, so that the ultrasound waves can penetrate into the gallbladder.

What do the following instruments detect (i want to understand the differences among them): ultrasound, mri, & an x-ray?
Different physics: Ultrasound images come from reflected sound waves so show "echogenicity" of tissues. X-ray images are like shadows - x-rays are blocked by denser materials ("radio-opaque" like bone, metal) and give "shadows" of what is not as dense. Mri images reflect differences in the chemical composition of the tissue (brain's gray matter v white; heart v lung; fat v muscle) via magnetic fields ; radio waves. ...Read more
Is it true that PT like ultrasound, tens, laser expose the body to radiation? Is it like X-Ray? What is the approx dose from 10 visits?
Physical Therapy: Uses non-ionizing radiation. Xray and CT are ionizing radiation, which you should seek to reduce exposure to whenever possible. However, ultrasound, TENS and laser use sound, electricity and light energy which are generally regarded as safe in these therapeutic amounts. ...Read more

Could be gallbladder: Your gallbladder lives just under your right ribcage; pain often radiates to the right shoulder, right armpit - but I've seen it radiate to the back, too. While gallbladder stones will show up on an ultrasound, sludge may not. The test that looks at the efficiency of the gallbladder's emptying is a hida scan - and it isn't typically done within the scope of an er visit. Talk to your doctor. ...Read more
