highlight inconsistencies immediately and will help diagnose any problems so they can be resolved

emphasizes the testing necessary to uncover defects and establishes tolerance levels for adequate performance of equipment

A

quality control

23
Q

included the examination of equipment, films and processing, image quality and facility personnel

A

mammography accreditation program (MAP)

24
Q

this was a major breakthrough in standardizing the quality of mammography

A

mammography quality standards act (MQSA)

25
involves film archiving and sharing patient records, reports and films with colleagues as requested by the patient
record keeping
26
according to MQSA, patient films and reports must be retained for at least __ years
5 years
27
suggests standardized terminology for mammographic findings and assigned category numbers for the assessment
breast imaging and reporting data system (bi-rads)
28
category that need additional imaging evaluation and or prior mammograms
category 0
29
category that there is nothing to comment on the breasts are symmetric, and no masses, architectural distortion or suspicous calcifications are present
category 1 negative
30
like category 1, this is a normal assessment but the interpreter chooses to describe a benign finding in the mammography report
category 2 benign findings
31
category that should have less than 2% risk of malignancy
category 3 benign finding - initial short interval follow up suggested
32
category that is reserved for findings that do not have the classic appearance of malignancy but have a wide range probability of malignancy that is greater than those in category 3
category 4 suspicious abnormality - biopsy should be considered
33
most recommendations of breast interventional procedures will be placed within this category
category 4 suspicious abnormality - biopsy should be considered
34
category have these lesions that have a high probability (95%) of being cancer this category contains lesions for which one stage surgical treatment could be considered without preliminary biopsy
category 5 highly suggestive of malignancy - appropriate action should be taken
35
category that is reserved for lesions identified on the imaging study with biopsy proof of malignancy prior to definitive therapy
category 6 known biopsy - proven malignancy - appropriate action should be taken
36
for any QA program to work, it must be reviewed ______ to check its effectiveness against updated technology
periodically
37
the most time consuming component of a QA program is the testing performed on the equipment also known as QC
equipment testing
38
the physicists and the ____ perform all the QC tests, and the results must be reviewrd quarterly by the radiologist
technologist
39
also knoen as processor QC ensures that the delicate chemical balance used for processing films remains consistent
sensitometry
40
sensitometry testing of the processor must be performed ____ and before clinical films are processed to obtain an accurate assessment of the consistency of processing quality
daily
41
the counters and processor film tray should be cleaned ____ to help reduce dust
daily
42
all places where dust accumulates should be thoroughly cleaned once a ____
week
43
one of the most important aspects of a QA program is ______ ______
phantom imaging
44
is a square acrylic block with a wax insert containing simulated masses, fibrils and calcium specks of varying sizes
mammography phantom
45
the phantlm approximages a breast of _._cm thickness
4.5 cm
46
to ensyre that the unit is mechanically stable and properly working
visual checklist
47
any equipmeny that is malfunctioning should be reported immediately to the _____ _____ to prevent possible harm to patients
service engineer
48
it is a way to evaluate the reason films in a department are repeated or thrown out it points out insufficiencies or waste in the imaging chain that might otherwise go unnoticed
repeat/reject analysis
49
the _______ check is performed as an image QA test and as a safety test technologists checks the pressure applied to the breast
compression check
50
according to MQSA, a compression force of at least __ pounds (111 newtons) is necessary for a unit to obtain good quality images
25 pounds
51
for patient safety, the maximum amount of force allowed by MQSA is __ pounds (209 newtons)
47 pounds
52
is done to assure that fogging on the film is not occurring from cracks in safe lights or from other sources that might filter in white light
darkroom integrity and fog test
53
______ of mammographic film caused by incidental exposure to white light will reduce the contrast on the film
fogging
