DMSO 1110 MIDTERM SOLVED 100% CORRECT.
CT - (ANSWER)An X-ray exam using multiple beams which produce a cross sectional image.
MRI - (ANSWER)-Uses the property of protons aligning themselves in a magnetic field and their reaction
to radio frequency waves.
-The machine scans the body by turning small magnets on and off.
Nuclear Medicine/ Pet Scan - (ANSWER)Uses small amounts of radioactive materials called radiotracers,
a special camera and a computer to help evaluate organ and tissue functions.
PACS - (ANSWER)-All diagnostic imaging is saved to PACS
-Picture archiving and communication system
-Saves images in Dicom format
-Allows interface with RIS (radiology information system) which populates the patient information.
-Allows for query/retrieve function to compare exams.
prone position - (ANSWER)lying on abdomen, facing downward.
supine position - (ANSWER)lying on back, facing upward
Ultrasound - (ANSWER)A mechanical wave. The Physical principals of the transmission of high frequency
mechanical sound waves.
Sonography - (ANSWER)Uses ultrasound to produce images.
Medical Use - (ANSWER)Typical medical use is 2 MHz to 20 MHz.
Benefits of Ultrasound - (ANSWER)-Does not use radiation
-Operator dependent
-Dynamic
, DMSO 1110 MIDTERM SOLVED 100% CORRECT.
-Portable
-Less expensive than other modalities
Sonographer Role/Duties - (ANSWER)*Check patient's chart to investigate prior exams and notes
*Verify patient's DOB and Name
*Perform exam based on appropriate protocols
*Summarize findings using sonographic terminology to provide the radiologist with an overview of the
exam
*The Scope of Practice and Clinical Standards for the Diagnostic Sonographer States "The sonographer
integrates medical history, previous studies and current symptoms in determining the appropriate
diagnostic protocol"
*Sonographer salary between $70,000 and $74,00.
Compression - (ANSWER)the part of a sound wave in which the molecules are pushed closer together.
Rarefraction - (ANSWER)the part of the sound wave in which the molecules are pulled apart.
Gain - (ANSWER)Amplification of the returning echoes received by the transducer.
Resolution - (ANSWER)ability to discriminate between two adjacent structures.
Piezoelectric Effect - (ANSWER)An electrical pulse is applied to each of the elements, and they expand
and contract producing mechanical energy.
Units of depth - (ANSWER)in centimeters
How is the echo created? - (ANSWER)by reflection between different tissue types.
Sound travels faster through? - (ANSWER)Denser mediums.
