Intro to Radiology Flashcards
how many modalities are there in radiology?
-7
which modality of radiology shoots X-rays at patients, which get blocked to varying degrees
- Xray
which modality of radiology utilized real time xrays
- fluoroscopy
which modality of radiology uses X-rays of vessels using IV contrast
- angiography
which modality of radiology uses an X-ray machine that swivels around the patient and gives a 3D image
- CT
which modality of radiology images using magnets to excite protons
- MRI
which modality of radiology images using echoes from sound waves
- ultrasound
which modality of radiology injects something radioactive and looks at the radiation emitted from the patient
- nuclear medicine
in Xrays, structures that are denser or have a higher atomic number are
- lighter
X-rays are good for
- high contrast structures
which modality of radiology is an X-ray that uses low energies to bring out differences between fat and soft tissue?
- mammogram
which is a real time x-ray that uses barium or some other contrast agents to fill the viscous and provide contrast. These are also good for GI investigations
- fluoroscopy
which modality of radiology is best for spatial resolution
- X-ray
which modality of radiology is best for soft tissue contrast
- MRI
which modality of radiology is best for low radiation
- MRI
- ultrasound
which modality of radiology is fastest
- X-ray
- Fluoro
- Angiography
- CT
which modality of radiology is the most affordable cost
- X-ray (cheapest)
- ultrasound
which is best for heart, lungs, bowels with air
- Xray
which is best for GI investigations
- fluoro
which is best for vessels and interventions
- angiography
which is best for most body parts
- CT
which is best for soft tissues and if the patient is young or pregnant
- MRI
which is best for fluid-filled structures, superficial parts or if the patients is young or pregnant
- ultrasound
which is best for functional/physiologic imaging; whatever the specific target of the study is
- nuclear medicine
which is best for contrast resolution
- MRI
which have ionizing radiation
- X-ray
- fluoro
- Angiography
- nuclear medicine
- CT
which uses magnetic resonance
- MRI
which uses sound waves
- ultrasound
which has the best spatial resolution
- X-rays
which has the worst spatial resolution
- nuclear medicine
in which type are physiologic and anatomic data gained simultaneously
- nuclear medicine
in nuclear medicine, which scan uses radio labeled glucose in the diagnosis of cancers
- PET scan
