Ch. 4 Mammo Flashcards
Which of the following statements is true ?
Q.1 pg124
Compression increases the uniformity of the breast, making diagnosis easier
The maximum compression force applied to the breast should not exceed
Q.2 pg124
None of the above
In assessing the degree of compression for any one patient, the technologist should take into consideration
1. The maximum to which the patient’s breast can actually be compressed
2. The amount of compression the patient can tolerate
3. Compression that should be just sufficient to immobilize the breast
1 & 2 only
Manual compression in mammography
Q.4 pg124
Depends on breast size and the patient’s pain tolerance
Some considerations that could be given to women with painful breasts include
1. Having the patient take ibuprofen prior to mammography
2. Scheduling mammography during the menstrual cycle
3. Explaining, before the examination, the importance of compression
Q.5 pg124
1 & 3
If a lesion is seen only on MRI of the breast, which of the following can be used to biopsy the lesion
Q.6 pg 124
MRI-guided code biopsy
Compression allows reduced radiation to the breast by
Q.7 pg124
Decreasing breast thickness
What principle does compression use to visualize the borders of circumscribed lesion
1. It brings the lesion closer to the detector
2. It spreads apart overlapping tissue
3. It separates superimposed areas of glandular tissue
Q.8 pg125
1,2,3
Ideally, breast compression is maximized when
1. Accompanied by a thorough explanation to increase patient cooperation
2. The exposure is made on arrested inspiration to reduce motion
3. The patient recognizes the advantage of compression in reducing radiation dose
Q.9 pg125
1&3 only
Magnification can be used to assess the
Q.10 pg125
Margins of a lesion
With calcifications, magnification can be used to assess
1. The number
2. Morphology
3. Tissue distribution
Q.11 pg125
1,2&3
The last degree of compression should be applied
Q.12 pg125
As gentle as possible or by using manual compression
Which of the following projections is used to determine whether a lesion is medial or lateral to the nipple?
Q.13 pg125
Craniocaudal (CC)
If any breast tissue is poorly imaged on the mediolateral oblique (MLO) projection, it is likely to be
Q.14 pg125
Medial breast tissue
The length of the posterior nipple line (PNL) visualized on CC projection, should be within how many centimeters of the PNL on MLO projection
Q.15 pg125
1.00
Which of the following conditions must be met when imaging the breast in MLO projection?
1. The pectoral muscle should extend to or below the PNL
2. Visualized fat should be posterior to all the fibroglandular tissues
3. The inframammary fold (IMF) should be open
Q.16 pg126
1,2,3
In positioning for the CC projection, If the C-Arm of the mammography unit is raised too high, the inframammary fold (IMF) is over elevated, resulting in loss of
- Superior breast tissue
- Inferior breast tissue
- Posterior breast tissue
Q.17 pg 126
2 & 3 only
Which of the following single projections will best visualized the maximum amount of breast tissue ?
Q. 18 pg126
MLO
In general, when imaging tall, thin patients, the angulation is adjusted to
Q.19 pg126
Close to 60 degrees
Which of the following positions is used to determine whether an abnormality is superior or inferior to the nipple?
Q.20 pg126
MLO
The principle of mobile versus fixed tissue is use in mammography positioning to image the maximum
Q.21 pg126
Medial breast on the MLO projection
In the CC projection of the breast, the detector is positioned
Q.22 pg126
At the level of the raised inframammary fold (IMF)
In positioning for MLO projection, the tube is always angled
Q.23 pg126
None of the above
What position is shown in Fig. 4-1?
