How they work
The way that X-Rays work.
Using a source of ionizing radiation (x-ray tube) and something to record (digital reader). (Can be done with or without contrast.
The common use of X-Ray.
What is chest x-rays, abdomen, and skeletal images?
The pros and cons of X-Ray.
What is advantages for X-rays are that they are inexpensive, portable, and widely used, and disadvantages is that they use ionizing radiation (can cause mutations in genetic material leading to cancer) and they have a limited range in density?
The five basic densities of X-Ray fromo least to most dense.
Air (darkest), fat, soft tissue or fluid, calcium (bone), and metal (lightest; can be contrast media, aesthetic, something abnormal).
A picture archiving, communications, and storage- used to share across facilities and platforms
What is PACS systems?
The way that CT works.
What is a rotating x-ray beam (ionizing radiation) and detector rays, that generates imaging's in pixels and allows for more shades than x-rays?
The common use of US.
What is to look at soft tissue and blood flow, as well as differentiate cystic (sac) vs solid lesion (tumor)?
The pros and cons of CT imaging.
What is the advantages of CT imaging is that it is fast and cornerstone of cross section imaging, and the disadvantage is the expensive equipment, not portable, need viewing room, and ionizing radiation?
Allows for windowing and multiple planes and 3D options.
What is CT imaging?
What is conventional radiography (X-ray imaging, computed tomography (CT), ultrasonography (US), magnetic resonance imaging (MRI), nuclear medicine imaging, and fluoroscopy?
The way that US works.
What is uses acoustic energy, a probe/transduce + gel that allows for the spread of sound and produces a signal to record the sound bouncing back?
Common use of a CT.
What is cross-sectional imaging?
The pros and cons of US.
What is the advantages of ultrasound are safer in children/pregnant women, less expensive, and portable, while the disadvantages is that it does not do the same as CT?
The PA and AP X-Ray views are done.
What is posterior closest to source and anterior against x-ray film/detector for PA, and anterior closest to source and posterior against x-ray film/detector?
The orientation for imaging.
What is anatomical position?
The way that MRI works.
What is that MRI utilizes potential energy stored in body's hydrogen ions, the magnetic field causes hydrogen ions to flip and flip back to another form that releases energy with the flip?
Dense tissue appears really dark.
What is MRI imaging picture?
The pros and cons of MRI imaging.
What is the advantages of MRI is that it is similar to CT with more tissues differentiation, reconstruct in any plane, does not use ionizing radiation, and the disadvantages are that it is expensive?
One Highlights fat, and the other highlights fat and water.
What is the difference between T1 and T2 MRI images?
When viewing an image the position is standing at the feet looking up.
What is cross section orientation?
The way that nuclear medicine imaging works.
What is a radioactive isotope is administered, targeting a particular tissue and emits positrons for detection?
The common use of nuclear imaging.
What is used for physiological and finding cancer 90% of the time?
The pros and cons of nuclear imaging.
What is the advantages are that it is relatively safe, and the disadvantages is that you are exposing others to radioactive particles?
The difference between PET and SPECT.
What is positron emission tomography (radioactive isotopes: short half life), and single photon emission computed tomography (r isotope-longer half life and cheaper)?
When viewing an image the patient is at the left.
What is sagittal section orientation?
