Layers of lead sheet
X Ray film emulsions are sensitive to light.
If the patient's hands are in the field of the xray they will appear on the film, so even if they are on the stomach they will appear as if they are over or near the spine. If someone has helped immobilise the patient for the xray, then their hands may appear on the film.
Everything fades. However, old Xray films are the same as black-and-white photographic film. They last 100 years plus and counting. There is a big business in converting Xray films to computer files and then harvesting the film for the silver.
If by XRAY, you mean a plain film, which is to say a modality that uses Rontgen radiation, then, no. The adrenals need either CT, ultrasound or MRI to visualize the adrenals.
It will depend on who says it, but often "plain x-ray" or "plain film" images are used to describe procedures using xray excluding things like CT or Fluoroscopy. If a single images is taken it will usually be considered "plain".
Crust, Mantle, and Core are the 3 layers in the earth.
Jewelry can cause "artifacts" on film, that may make it difficult to see the rest of the film. There can be bright streaks on film due to xray beams being reflected off the metal.
what are the three layers of a vein
There is no antonym. An xray is a wavelength. There is no opposite.
If the film is too dark, the xray needs to be retaken with lower kV and mAS settings. Xrays that are only marginally too dark can be looked at under a bright light.
Jupiter has 3 layers of clouds.
