AR 2:00 1A", the area described is : - answerAntiradial 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 : - answerIn the lateral breast A transducer that can operate at multiple frequencies is said to have : - answerBroad bandwidth All of the following statements about high-frequency transducers are true : - answer- Axial resolution is increased - Lateral resolution is increased - Sound penetration is decreased - Best for breast imaging The following statement about high-frequency transducers is false : - answerSound travels faster Decreasing depth will : - answerIncrease the frame rate Increasing the overall gain control will : - answerCause artifactual echoes What allows for better demonstration of small, tortuous vessels ? - answerPower doppler What affects the frame rate ? - answerNumber of focal zones and size of image Ideally, the elevational focus for breast imaging should be fixed at : - answer1.5 cm An increase in the intensity of echoes beneath a structure is called : - answerEnhancement What is not a good indication for performing a breast sonogram? - answerEvaluate a mass for microcalcifications When setting the TGC control for breast imaging, the following tissue should demonstrate a medium level of gray. - answerFat The lactiferous ducts are best seen when scanning : - answerRadial The orthogonal (defined as perpendicular) view from the longitudinal scan is : - answerTransverse Adequate penetration of the breast is determined by imaging the : - answerPectoral muscles If a mass is isoechoic with surrounding tissues, what maneuver would accentuate the mass to make it show up better ? - answerApply harmonics What transducer feature would not be good for breast imaging ? - answerCurved linear array format Lateral resolution is best at the : - answerFocal zone Which technique would eliminate useful artifacts such as posterior enhancement and shadowing? - answerSpatial 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 ? - answerPatient's social security number What is considered an appropriate annotation method for breast imaging ? - answer- Side / Quadrant - Clock face - 123-ABC What statement would be false when considering doppler artifacts ? - answerIf 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 the 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 : - answerTransducer frequency What would not be part of the examination preparation? - answerPresent the informed consent to the patient for signature What would be part of the examination preparation? - answer- Obtain pertinent clinical information from the patient. - Explain the examination to the patient. - Review the pertinent correla
