What are the disadvantages and advantages of gamma rays?

Answer 1

1. cheap x-rays adv.

2. easy to do

3. fast results

4. can be done anywhere even in bedside

disavd.

1. radiation

2. has limited detection ability, can't detect small nodes or deeper structures very well

CAT scan - a higher version, uses also xray

adv.

1. better than x-ray, esp. if with contrast

2. non-invasive and good

3. OK for claustrophobics

disavd.

1. may require contrast which should be injected, therefor, can't have it if you have Allergies to iodine (shellfish, etc.)

2. more expensive than xray

3. some radiation

MRI avd.

1. far better than CT scan, esp when it involves smaller structures (can detect tumor as small as 0.5 cm)

2. non-invasive, uses magnetic energy, no radiation

disadv.

1. magnetic, can't do if you have metals inside (pins, prosthesis, pacemakers)

2. you'll be put inside a cylindrical thing, not good for claustrophobics (although they may be sedated prior)

3. Humming sound makes you paranoid or annoyed (you're alone, confined inside a cylinder)

4. more expensive

Nuclear imaging - ex. Positron emission tomography

adv.

1. excellent imaging, precise

2. shows not only structure, but also on how and when these structures will function

disadv.

1. very expensive

2. lots of preparation on patient

3. not all hospitals have it, cause maintenance costs are high.

4. radioactive isotopes poses risks for technicians (but not if they are careful).

Answer 2

advantage is that we can find out if there is a fracture in the bone.

disadvantage is that our body gets exposed to harmful rays and our cells can get mutated . so one should not have his or her x ray taken more than 3 or 4 times

Answer 3

Pros:

Can see broken bones

Useful diagnosis tool

Quick and easy to use

Painless

Can look inside the body without cutting flesh

Cons:

Very expensive - about £4000 to £4500

Can make you ill if you get an x-ray too often

Answer 4

Gamma rays are the highest forms of electromagnetic radiation. They are a type of ionizing radiation, and they can damage tissue. This can lead to radiation sickness or, in sufficient doses, it can kill.

---------------------------------------------------------------

Gamma Rays are able to kill living cells so it's used as medicine to kill cancerous cells. If there's an overdose though, it could kill you. It is a hazardous radiation so if you're not specialized in it, then DO NOT mess with Gamma Rays because again, too much could kill you.

Answer 5

Advantages of X-Rays :

One advantage of X-rays is that they are cheaper than similar medical procedures.

An advantage to X-rays is that they are easier to use than MRIs or CT scans.

The use of X-rays as a treatment is known as radiation therapy and is largely used for the management (including palliation) of cancer; it requires higher radiation energies than for imaging alone.

Computed tomography (CT scanning) is a medical imaging modality where tomographic images or slices of specific areas of the body are obtained from a large series of two-dimensional X-ray images taken in different directions. These cross-sectional images can be combined into a three-dimensional image of the inside of the body and used for diagnostic and therapeutic purposes in various medical disciplines.

Disadvantages of X-Rays :

They do not give detailed images of the body.

Radiation exposure is probably the biggest concern patients have with X-rays.

X-rays can cause genetic mutations in both body cells and sex cells.

Biological radiation effects is very destructive to any sort of living tissue and in a person it can cause DNA mutation.

Answer 6

you can see through opaque objects

it gives off radiation
