what does the x mean in x ray?
unknown type of radiation
x-rays make up x-radiation, a form of high-energy electromagnetic radiation. most x-rays have a wavelength ranging from 0.01 to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (3×10 hz to 3×10 hz) and energies in the range 100 ev to 100 kev. x-ray wavelengths are shorter than those of uv rays and typically longer than those of gamma rays. in many languages, x-radiation is referred to as röntgen radiation, after the german scientist wilhelm röntgen who discovered it on november 8, 1895. he named it "x-radiation" to signify an unknown type of radiation. spelling of "x-ray(s)" in the english language includes the variants "x-ray(s)", "xray(s)", and "x ray(s)".
x-ray
retrograde pyelogram (rpg). x ray study of the kidney, focusing on the urine-collecting region of the kidney and ureters.









































antegrade nephrostogram.









































ct scan. a special imaging technique that uses a computer to collect multiple x ray images into a two-dimensional cross-sectional image.









































mri with intravenous gadolinium. a special technique used to image internal structures of the body, particularly the soft tissues. an mri image is often superior to a routine x ray image.
