The right answer is ultrasound.
Ultrasound is an imaging technique that uses ultrasound. It is used routinely in human and veterinary medicine, but can also be used in research and industry.
Contrast ultrasound is one that uses a contrast medium. The contrast medium composed of microbubbles is injected into the bloodstream intravenously at the time of the ultrasound examination of the patient. The microbubbles of the contrast medium are highly reflective to ultrasound during ultrasound examination; thus making it possible to image the blood vascularization of the organs for diagnostic purposes.
It is very important to not inhale chemicals because when strong acids and bases get into your lungs, they mix with the water in your lungs and can cause burns. Your lungs are sensitive to many chemicals because the alveoli sacs are on one cell layer thick.
Even though they say you can waft, it is really not good to even do that if it has any toxicity. Carcinogenic means something that can give you cancer, but it does not harm you right away, same thing with chemicals.
Lead for example is sweet, but toxic. The Romans used to flavor their food with lead compounds. If there is any doubt read a Material Safety Data Sheet! It will tell how it is toxic and what is is safe for.
