Chapter 6: Lange Mammography Practice Test 1 Already Passed Radiation therapy is a treatment that utilizes (A) drugs to treat cancer that may have spread (B) high-energy radiation to destroy cancer cells (C) radioactive tracers to track the path of cancer to the lymph nodes (D) potent pain medication to treat the severe pain from cancer B Between ages 20 and 30 years, an asympto- matic woman should be undergoing mammo- graphy every (A) year (B) 2 years (C) 3 years (D) none of the above D Medical history may include questions on hormone use because (A) treatment with synthetic hormones, such as hormone replacement therapy (HRT), will always cause breast cancer (B) the use of reproductive hormones can increase risk factors for breast cancer (C) family history of hormone use predis- poses a woman to cancer (D) personal history of hormone use decreases a woman's risk for breast cancer B In imaging implants, some of the projections taken will include an image of the implant. In these projections, compression is used (A) to allow a uniform tissue density (B) for immobilization only (C) to separate the breast tissue (D) to separate and spread out the implant B The glandular dose is a measure of (A) the radiation dose to the skin of the breast (B) the dose to the radiosensitive cells of the breast (C) the significant background dose recorded in the US (D) the radiation dose to the gonads B In digital imaging, "high detective quantum efficiency" means that (A) the system is more efficient in convert- ing input x-ray signals and/or the system needs higher exposure factors to create an image (B) the system needs higher exposure factors to create an image and/or the system has a high fill factor on the TFT array (C) the system is more efficient in converting input x-ray signals and/or the system has a high fill factor on the TFT array (D) all of the above C In digital imaging, a graph of the optical den- sity range to the log of relative exposure is a (A) shallow sloping curve (B) steep sloping curve (C) linear response (D) curvilinear response C In the new 2016 American College of Radiology (ACR) Digital Mammography Quality Control Manual, the approved accreditation phantom has a total of (A) 5 fibers, 5 speck groups, and 5 masses (B) 5 fibers, 6 speck groups, and 5 masses (C) 6 fibers, 5 speck groups, and 5 masses (D) 6 fibers, 6 speck groups, and 6 masses D The circular pigmented area around the nip- ple is called the (A) skin (B) areola (C) Montgomery gland (D) ampulla B Keratosis is demonstrated mammographically as a (A) sharply outlined multilobulated lesion (B) sharply outlined lesion with a halo (C) mixed radiolucent and radiopaque cir- cular lesion with a radiolucent center (D) mixed radiolucent and radiopaque oval lesion A Figure 6-1 indicates (A) mammographically benign calcifications (B) malignant calcifications (C) keratosis (D) fibroadenomas *no image* A The advantages of a quality assurance program, such as the Mammography Quality Standards Act (MQSA), includes all of the following except (A) increased efficiency (B) cost-effectiveness (C) permission for manipulation of the final image (D) improved patient satisfaction C In magnification, what immediate role does the large object-to-image receptor distance (OID) play in reducing scattered radiation? (A) It allows the use of lower peak kilovolt- age (kVp) values. (B) There is increased source-to-object dis- tance (SOD), which allows for absorp- tion of the scattered radiation. (C) Most of the scattered radiation misses the detector. (D) The larger OID utilizes a smaller source- to-image receptor distance (SID). C Using
