X-Ray Basics
This part of the body appears white on an X-ray because it absorbs more radiation than soft tissue.
Bones
The abbreviation “CT” stands for this type of imaging scan.
What is Computed tomography
MRI is unique among imaging techniques because it does NOT use this.
What is radiation?
This imaging method uses high-frequency sound waves instead of radiation.
What is ultrasound?
Doctors who specialize in interpreting medical images.
Who are radiologist?
Doctors most commonly order this imaging test first when they suspect a fracture.
What is an X-ray?
CT scans are especially useful for quickly detecting this dangerous condition after trauma.
What is internal bleeding?
MRI machines use extremely powerful versions of these to create images.
What are magnets?
Ultrasound imaging is commonly used to monitor this during pregnancy.
What is fetal development?
The hospital department responsible for performing imaging tests.
What is the radiology department?
This protective material is worn during X-rays to reduce radiation exposure.
What is lead apron?
CT scanners create images by combining many X-ray images taken from different directions into these.
What is cross sectional slices?
MRI scanners detect signals primarily from this element found in water molecules in the body.
What is hydrogen?
This imaging scan uses a small radioactive tracer to show how organs function.
What is a PET scan?
This safety principle in radiology means keeping radiation exposure “as low as reasonably achievable.”
What is the ALARA principle
This discovery in 1895 led to the development of modern radiology. (And who discovered it)
What is the discovery of X-rays by Wilhelm Conrad Röntgen?
This injected substance helps highlight blood vessels and organs during many CT scans.
What is contrast dye?
Patients with certain metal implants cannot undergo MRI because of this powerful component of the machine.
What is the string magnetic field?
PET scans are frequently used to detect and monitor this disease.
What is cancer?
CT scans expose patients to more radiation than this simpler imaging method.
What is an X-ray?
The type of radiation used in X-ray imaging that has enough energy to remove electrons from atoms.
What is ionizing radiation?
This major advantage of CT scanning makes it critical in emergency medicine compared to MRI.
What is speed or rapid imaging?
Compared to CT scans, MRI is generally better at imaging these types of tissues.
What are soft tissues
PET imaging works by detecting areas of high use of this substance, which many cancer cells consume rapidly.
What is glucose?
This medical specialty uses imaging guidance to perform minimally invasive treatments such as placing stents.
What is interventional radiology?
