b-destructive c- decreased d- ablative Magnetic Resonance Imaging (MR) is the modality of choice for demonstrating: -
CORRECT ANSWER -a- information from one parameter
b- skull fracture c- central nervous system and spine d- bone mineral density _____________ enlargement causes expansion and erosion of the sella turcica. -
CORRECT ANSWER -a- adrenal
b-amygdala c- hippocampus d- pituitary The pathology most often demonstrated in the upper lobes and lung parenchyma with a radiographic appearance of multiple, well-defined, scattered nodules of uniform density
is: - CORRECT ANSWER -a- asbestosis
b- silicosis c- anthracosis d- tuberculoma
- Failure of the technologist to obtain an adequate patient history may result in a
repeatable error in technical factors due to: - CORRECT ANSWER -a- existing
pathologic conditions b- fluctuation in voltage c- fluctuation in amperage d- existing digital conditions CT can detect tissue density differences as low as ____% or less aiding in differential diagnosis of pathologies compared to conventional radiography that have at least a
_____% difference. - CORRECT ANSWER -a- 5:
b- 1: c- 10: d- 1: The technique of using Magnetic Resonance Imaging (MR) makes use of the radio portion of the electromagnetic spectrum with _________ wavelengths of 103 to 10-
meters which are considered _________ wavelengths. - CORRECT ANSWER -
a- electron long b- electron short c- photon long d- photon short CT and conventional radiography measure the ____________ of the x-ray beam; MR uses a technique that stimulates the body to produce a _____________signal and a
receiver coil to measure the signal. - CORRECT ANSWER -a- attenuation
placement b- resolution placement c- attenuation radiofrequency d- resolution radiofrequency The ability to show soft-tissue contrast is referred to as contrast resolution; _________ demonstrates this better than _______________; ____________ is the imaging system that is more sensitive to slight differences in tissue compensation of the white and gray
matter of the brain. - CORRECT ANSWER -a- CT conventional radiology MR
b- MR CT conventional radiology c- conventional radiology CT NM d- conventional radiology MR NM Left untreated, interstitial pneumonia may cause "honeycomb lung"; on CT this is demonstrated as _______________ spaces and dense _______________ walls. -
CORRECT ANSWER -a- fibrotic cystlike
b- cystlike fibrotic c- parenchyma cystlike d- cystlike parenchyma The examination of choice for a stroke patient is _________ or ______________; as the infarct ages a combination of MR and _________is more sensitive than _______ in
detecting an infarct or ischemic edema. - CORRECT ANSWER -a- US non
contrast CT MR MRA b- CT US CT MRA c- NR non contrast CT MRA CT d- MR US MRA CT
CT, radionuclide imaging, angiography, and MR are best used to demonstrate the presence and extent of __________________ disorders of the cardiovascular system. -
CORRECT ANSWER -a- functional
b- primary c- secondary d- positioning The 2D or 3D imaging technique that relies primarily on flow-related enhancement to distinguish moving from stationary spins in creating MRI angiograms is termed: -
CORRECT ANSWER -a- time of flight angiography
b- contrast resolution c- radiofrequency d- rephrasing gradient __________________ is the term used to describe the method by which images acquired in the axial plane may also be reconstructed in the coronal or sagittal plane. -
CORRECT ANSWER -a- matrix
b- multiplanar reconstruction c- linear attenuation coefficient d- voxel
