Question

Radiology deals with the study of
(a) UV rays
(b) Gamma rays
(c) Cosmic rays
(d) X-rays

Answer 1

Hint: High energy electromagnetic radiation with a wavelength of 10picometers to 10nano nanometers used in first-line medical imaging techniques of radiology.

Complete answer:
To diagnose or treat disease in the body of the animal as well as the human body doctors or health care professionals used medical imaging. Radiology is the branch of science that deals with medical imaging techniques. Various medical imaging techniques used to diagnose or treat disease are X-rays, a computed tomography(CT), ultrasound, positron emission tomography(PET).

Additional Information: - A medical doctor who completed a postgraduate in radiology is called a radiologist. He or she communicated with the physician by reports verbally about medical imaging and they can perform minimally invasive procedures using medical imaging techniques.
- Radiographs are generally referred to as images of a person’s internal body created by passing a beam of X-rays with calculated frequency.
- when X-rays are passed through a person, based on the X-rays passed through the body versus X-rays absorbed by the body(X-rays scattered), an image is formed.
- Because of its availability, speed, and low cost compared to other medical imaging techniques, X-rays are used as a first-line choice for the diagnosis of a disease.
So, the correct answer is ‘X-rays’.

Note: -X- rays were discovered by a german mechanical engineer and physicist Wilhelm Conrad Rontgen in 1895, awarded the Nobel prize in physics in 1901 for the discovery of X-rays.
-Applications of low energy projectional radiography are mammography used to detect breast cancer and Dual-energy x-ray absorptiometry that is used for diagnosis of osteoporosis.
