Correct Answer
C. LympHoscintigrapHy
Explanation
Lymphoscintigraphy is a technique used to inject a radioisotope directly into the tumor bed to track the extent or spread of a cancer. This procedure helps in identifying the lymph nodes that are draining the tumor and provides valuable information about the spread of cancer cells through the lymphatic system. By visualizing the movement of the radioisotope, lymphoscintigraphy helps in planning the surgical removal of the tumor and determining the appropriate treatment strategy for the patient.
7.
Calcifications seen on the mammogram are suspected to be in the skin. The best projection necessary to prove this theory is the
Correct Answer
B. TAN
Explanation
The correct answer is TAN because the TAN projection (Tangential) is the best way to visualize calcifications in the skin. This projection involves positioning the breast so that the nipple is pointing towards the detector, allowing for a clear view of the skin and any calcifications present. The LMO projection (Latero-medial oblique) and LM projection (Latero-medial) are used to visualize different areas of the breast, while the AT projection (Anterior-Posterior) is used to visualize the breast from front to back. Therefore, TAN is the most appropriate projection for confirming the presence of calcifications in the skin.
8.
The breast meets the abdominal wall at approximately the:
Correct Answer
D. Seventh rib
Explanation
The breast meets the abdominal wall at approximately the seventh rib. This is because the breast tissue extends from the second to the sixth rib in the mid-axillary line, and then curves downward to meet the abdominal wall at the seventh rib. The other options, such as the mid-sternum, clavicle, and mid-axillary line, do not accurately represent the location where the breast meets the abdominal wall.
9.
The advantages of the MQSA include all of the following except:
Correct Answer
C. Allows manipulation of the final image
Explanation
The MQSA (Mammography Quality Standards Act) has several advantages, including increasing efficiency, being cost-effective, and improving patient satisfaction. However, one advantage that it does not provide is the ability to manipulate the final image. The MQSA focuses on ensuring the quality and accuracy of mammography screenings, rather than allowing for image manipulation.
10.
The specimen is compressed to
Correct Answer
C. Reduce tissue thickness
Explanation
The correct answer is "reduce tissue thickness". When a specimen is compressed, it reduces the thickness of the tissue, allowing for clearer imaging and reducing the potential for motion unsharpness. This compression technique is commonly used in mammography to improve image quality and enhance the detection of abnormalities. It also helps to reduce radiation exposure as thinner tissues require less radiation to penetrate. Additionally, by reducing the tissue thickness, it minimizes the magnification factor, resulting in more accurate measurements and evaluations.
11.
At higher magnification factors there is
1.) higher skin dose
2.) increased scatter
3.) decreased source-to-object distance (SOD)
Correct Answer
C. 1 and 3 only
Explanation
At higher magnification factors, there is an increased skin dose because the radiation is focused on a smaller area, resulting in a higher dose per unit area. Additionally, there is a decreased source-to-object distance (SOD) which can also contribute to a higher skin dose as the radiation has less distance to travel before reaching the skin. Increased scatter is not necessarily a direct consequence of higher magnification factors, so it is not included in the explanation.
12.
One of the minor risk factors for breast cancer could include
Correct Answer
D. Not breast-feeding
Explanation
Not breast-feeding is considered a minor risk factor for breast cancer. Breast-feeding has been shown to have a protective effect against breast cancer, as it helps to reduce the number of menstrual cycles a woman has in her lifetime. This, in turn, decreases the exposure to estrogen, a hormone that can promote the growth of breast cancer cells. Therefore, not breast-feeding may slightly increase the risk of developing breast cancer.
13.
What cancer accounts for a large percentage of potential malpractice suits for failure to detect breast cancer because it is difficult to diagnose?
Correct Answer
A. Lobular carcinoma in situ
Explanation
Lobular carcinoma in situ is a type of breast cancer that is difficult to diagnose because it does not form a lump or mass that can be detected through a physical examination or imaging tests. Instead, it involves abnormal cells in the lobules of the breast that have not spread to surrounding tissues. Due to its subtle nature, lobular carcinoma in situ can be easily missed during routine screenings, leading to potential malpractice suits if not detected in a timely manner. This explains why it accounts for a large percentage of potential malpractice suits for failure to detect breast cancer.
14.
The projection best used to demonstrate the true representation of medial breast structures in relation to the nipple is the
Correct Answer

The principle of elastography is that:
Correct Answer
A. Cancers are relatively hard compared with surrounding breast tissue
Explanation
The principle of elastography is based on the fact that cancers are relatively hard compared with the surrounding breast tissue. This means that when pressure or compression is applied to the breast, the cancerous tissue will not deform or compress as much as the surrounding normal tissue. By measuring and comparing the stiffness or elasticity of different areas of the breast, elastography can help to identify and locate potential cancerous tumors.
28.
In mammography, collimation is to:
Correct Answer
A. The detector
Explanation
Collimation in mammography refers to the process of restricting the X-ray beam to a specific area of interest. It involves adjusting the size and shape of the X-ray beam to match the size and shape of the detector. By collimating the X-ray beam to the detector, unnecessary radiation exposure to surrounding tissues is minimized, resulting in a clearer and more accurate image. Therefore, the correct answer is "the detector."
29.
Ultrasound uses
Correct Answer
A. High-frequency sound waves to image the breast
Explanation
Ultrasound uses high-frequency sound waves to image the breast. These sound waves are emitted by a transducer and penetrate the breast tissue. When the sound waves encounter different tissues, they bounce back and create echoes. These echoes are then converted into images by a computer, allowing healthcare professionals to visualize the internal structures of the breast. High-frequency sound waves are used because they can provide detailed images and are safe for the patient as they do not involve ionizing radiation.
30.
Using a small focal spot size is recommended for magnification
Correct Answer
A. To reduce the resultant loss of image detail
Explanation
Using a small focal spot size is recommended for magnification to reduce the resultant loss of image detail. This is because a small focal spot size produces a sharper image with better resolution, allowing for more accurate visualization of small structures and details. Using a larger focal spot size can result in a loss of image detail, as the larger size may cause blurring or smudging of the image. Therefore, using a small focal spot size helps to minimize this loss and improve the overall quality of the magnified image.
31.
A lesion moved up on the ML projection from it's original position on the MLO. The location of the lesion within the breast is
Correct Answer
B. Medially
Explanation
The lesion moved up on the ML projection, indicating a vertical movement. Since it moved from its original position, which was on the MLO (mediolateral oblique) projection, the lesion shifted towards the center of the breast. Therefore, the location of the lesion within the breast is medially.
32.
The patient will not have to authorize the release of biopsy results as required under HIPAA regulation because:
Correct Answer
B. HIPAA regulations allow a person subject to FDA jurisdiction to collect patients' biopsy information for MQSA medical outcome audits.
Explanation
The correct answer is HIPAA regulations allow a person subject to FDA jurisdiction to collect patients' biopsy information for MQSA medical outcome audits. Under HIPAA regulations, the release of medical information requires the patient's authorization. However, in this case, the person collecting the biopsy information is subject to FDA jurisdiction and is conducting medical outcome audits under MQSA. Therefore, they are allowed to collect the patients' biopsy information without the patient's authorization.
