Question

1. which of the following produces a radio frequency radiation pulse image of soft and hard tissue in multiple planes?

mri
x - ray
cat scan
pet scan

1. lasik laser surgery can be used to correct:

ocular styes
dry eye
myopia
conjunctivitis

Explanation:

• MRI (Magnetic Resonance Imaging) uses radio - frequency radiation pulses to create images of soft and hard tissues in multiple planes. X - rays use ionizing radiation and mainly show bone structures. CAT scans (CT scans) use X - rays and computer processing for cross - sectional images. PET scans use radioactive tracers to show metabolic processes.
• LASIK (Laser - Assisted In Situ Keratomileusis) is a laser eye surgery used to correct refractive errors like myopia (nearsightedness). Ocular styes are infections of the eyelid glands, dry eye is a condition related to tear production, and conjunctivitis is an inflammation of the conjunctiva, none of which are corrected by LASIK.

Answer:

1. MRI
2. myopia
