What are the advantages and disadvantages associated next to X-rays,CAT scan, nuclear imaging, and MRI technique
Answers: Some of them...
x-rays adv.
1. cheap
2. easy to do
3. hurriedly results
4. can be done anywhere even in bedside
disavd.
1. radiation
2. have limited detection competency, can't detect small nodes or deeper structures very economically
CAT scan - a higher reworked copy, uses also xray
adv.
1. better than x-ray, esp. if with contrast
2. non-invasive and honourable
3. OK for claustrophobics
disavd.
1. may require contrast which should be injected, therefor, can't have it if you enjoy 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 perkiness, no radiation
disadv.
1. magnetic, can't do if you own metals inside (pins, prosthesis, pacemakers)
2. you'll be put inside a cylindrical thing, not apposite for claustrophobics (although they may be sedated prior)
3. Humming sound make 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 single structure, but also on how and when these structures will function
disadv.
1. very expensive
2. lots of preparation on lenient
3. not all hospitals own it, cause preservation costs are high.
4. radioactive isotopes poses risks for technicians (but not if they are careful).
in attendance you have it...not really complete but those are most of the must-knows...
