Which application is not useful for routine breast cancer screening because it does not consistently detect certain early signs of cancer such as microcalcifications of calcium in the breast that cannot be felt but can be seen on a conventional mammogram?
Flouroscopy
PET
Sonography
MRI
Which of the following is NOT true about Sonography?
Safest of all imaging modalities
It is effective at imaging body parts that have gas in them or are hidden by bone, such as the lungs or head
It is the least expensive imaging modality
It utilizes a noninvasive imaging test and has no known complications
The SSD to the PT should not be less than 38cm when using stationary fluoroscopic units
True
False
This imaging modality is most useful in detecting brain cancer.
MRI
Sonography
CT Sim with Contrast
Flouroscopy
This image as acquired via which of the following imaging modalities
MRI with contrast
PET
CT Sim with contrast
Fluoroscopy
FDG - Fluorodeoxyglucose...
s a radionuclide that is administered during PET.
is a glucose analog
will congregate to any place where cells are turning over quickly, such as a location with metastatic tumor(s).
All answers are correct
has a 110-minute half life
Which of the following statement are false about an Electronic Portal Imaging Device - (EPID) ?
is mounted opposite the head of the gantry
converts x-ray information to digital information that can be displayed as an image on a computer screen.
These imaging systems rapidly produce static or real-time images of treatment volumes and computer manipulation of digital information enhances visualization, particularly beneficial to megavoltage (MV) imaging.
requires contrast material and or agent
Megavoltage computed tomography (MVCT) is used in the TomoTherapy treatment unit.
TRUE
FALSE
Which of the following is true about Computed Tomography (CT)?
Uses a fan beam created from an x-ray tube that rotates around the patient.
Single projection images are acquired at certain degree intervals while the gantry rotates resulting in a 2D extended digital array.
Results in a 3D data set with axial, sagittal and coronal planes that provide bony and soft tissue visualization.
Images are slightly offset from one another and are the foundation for which a 3D volumetric data set is produced.
This is a/an
Conventional Simulator
CT Simulator
CBCT
Fluoroscope
Positron Emission Tomography is NOT used in
Diagnosing many cancers
Sim in Radiation Oncology
Staging
Follow-up once treatment has concluded
Imaging the patient before treatment and matching the anatomy with the treatment plan
FDG is NOT useful in showing increased areas of metastatic disease and nodal activity.
TRUE
FALSE
What type of imaging modality is utilized for this image?
CT with contrast
Fluoroscopy
MRI
IVP
Contrast is NOT used in which of the following:
MV Imaging
PET
Fluoroscopy
MRI
