BREAST ARDMS Exam Questions And Answers (Verified And Updated) Which artifact may cause structures to look deeper than they actually are? - answer✔✔Propagation speed error The optimum operating frequency for a broad -bandwidth transducer would be : - answer✔✔10 MHz In breast sonography, what is NOT significantly affect ed by the limited field of view when imaging superficial structures? - answer✔✔Temporal resolution Which of the following affects the actual intensity of the sound utilized for imaging? - answer✔✔Output power The dynamic range of a display is the : - answe r✔✔Number of gray shades Using color/power doppler while a patient hums to better dilineate a mass is called : - answer✔✔Fremitus A standoff pad thicker than 1 cm is not recommended because it will : - answer✔✔Affect the optimal placement of the fixed elev ation plane focus Which type of transducer does NOT allow the sonographer to vary the focusing capabilities? - answer✔✔Mechanical sector When taking patient history for a breast sonogram, what information from a previous mammogram would not be considered r elevant? - answer✔✔Name of radiographer Image of amplitude is affected by : - answer✔✔Power, overall gain, and time gain compensation (TGC) High -frequency transducers used in breast imaging provide excellent resolution of breast tissues but limited : - answer✔✔Penetration When using the 123 -ABC method of annotation, "B" would indicate : - answer✔✔Mass is in the mammary zone In the 123 -ABC method of annotation, the number denote the : - answer✔✔Distance from the nipple Which method of patient positioning is the best for evaluation the medial aspect of the breast ? - answer✔✔Supine The two -handed technique is used to image : - answer✔✔The main breast duct and nipple Which of the following transducers would be the best choice for breast imaging ? - answer✔✔10 MHz linear array Selecting multiple focal zones will : - answer✔✔Decrease frame rate When viewing a mammogram, one always sees the marker in the region toward : - answer✔✔Axilla If a breast sonographic image is labeled "Rt. AR 2:00 1A", the area described i s : - answer✔✔Antiradial scan of the right breast, upper inner quadrant near the nipple, under the skin When viewing a mammogram, a mass is marked near the CC marker in the right breast. This will indicate to the sonographer that the mass is located : - answer✔✔In the lateral breast A transducer that can operate at multiple frequencies is said to have : - answer✔✔Broad bandwidth All of the following statements about high -frequency transducers are true : - answer✔✔- Axial resolution is increased - Lateral re solution is increased - Sound penetration is decreased - Best for breast imaging The following statement about high -frequency transducers is false : - answer✔✔Sound travels faster Decreasing depth will : - answer✔✔Increase the frame rate Increasing the ove rall gain control will : - answer✔✔Cause artifactual echoes What allows for better demonstration of small, tortuous vessels ? - answer✔✔Power doppler What affects the frame rate ? - answer✔✔Number of focal zones and size of image Ideally, the elevational focus for breast imaging should be fixed at : - answer✔✔1.5 cm An increase in the intensity of echoes beneath a structure is called : - answer✔✔Enhancement What is not a good indication for performing a breast sonogram? - answer✔✔Evaluate a mass for microcalcifications When setting the TGC control for breast imaging, the following tissue should demonstrate a medium level of gray. - answer✔✔Fat The lactiferous ducts are best seen when scanning : - answer✔✔Radial The orthogonal (defin ed as perpendicular) view from the longitudinal scan is : - answer✔✔Transverse Adequate penetration of the breast is determined by imaging the : - answer✔✔Pectoral muscles If a mass is isoechoic with surrounding tissues, what maneuver would accentuate the mass to make it show up better ? - answer✔✔Apply harmonics What transducer feature would not be good for breast imaging ? - answer✔✔Curved linear array format Lateral resolution is best at the : - answer✔✔Focal zone Which technique would eliminate useful a rtifacts such as posterior enhancement and shadowing? - answer✔✔Spatial compound imaging According to AIUM standards, all of the following information should be indicated on sonographic images : - answer✔✔- Patient's name / ID # - Patient's age - Facility name - Date What information should not be indicated of sonographic images ? - answer✔✔Patient's social security number What is considered an appropriate annotation method for breast imaging ? - answer✔✔- Side / Quadrant - Clock face - 123-ABC What stateme nt would be false when considering doppler artifacts ? - answer✔✔If the gain and filter settings are too low, it can cause noise What statements are true when considering doppler artifacts ? - answer✔✔- If the filter setting is too high, it will inhibit th e ability to detect low -velocity blood flow. - A PRF / velocity scale that is too low will cause aliasing. - If the doppler angle is perpendicular to flow, no flow will be detected. - Spectral mirroring causes a duplication of the waveform on the opposite side of the baseline What is true about propagation speed error ? - answer✔✔- If the propagation speed is slower than 1540 m/sec, posterior echoes will be displayed on he sonogram deeper than they actually are. - If the propagation speed is faster than 1540 m/sec, reflectors will appear closer to the transducer than they actually are. The brightness of echoes on an ultrasound image is affected by : - answer✔✔- Overall gain - Power output - Dynamic range - TGC The brightness of echoes on an ultrasound image is not affected by : - answer✔✔Transducer frequency What would not be part of the examination preparation? - answer✔✔Present the informed consent to the patient for signature What would be part of the examina tion preparation? - answer✔✔- Obtain pertinent clinical information from the patient. - Explain the examination to the patient. - Review the pertinent correlative imaging tests. - Know the indication for the exam. The supine oblique postition : - answer✔✔- Evenly distributes the breast tissue - Allows better evaluation of the outer breast. - Places the nipple in the center. - Minimizes breast thickness for better penetration Echo palpation is used to : - answer✔✔- Localize a mass. - Determine if a mass is c ompressible or not. For general breast scanning, which patient position is considered the best? - answer✔✔- Supine oblique. - Contralateral posterior oblique.
