What are the two routine projections/views for mammography imaging? - ANSWER-MLO (Mediolateral Oblique) & CC (Craniocaudal)
A trauma patient has a CT scan for their head and an augmented Chest, Abdomen, Pelvis. Why is the head done first? - ANSWER-Because a brain bleed or other pathologies can be identified prior to contrast being introduced since the contrast appears white and similar to that of a fresh brain bleed; the contrast study of the Chest, Abdomen, would leave contrast stuck in the Blood Brain Barrier for up to 10 hours before it clears out
What does the acronym DICOM stand for and what are four functions that it performs? - ANSWER-Digital Imaging and Communication in Medicine (DICOM) is a standard for handling, storing, printing and transmitting information in medical imaging
What is the Fowler's position? - ANSWER-Patient recumbent with head of the bed raised 40-60 degrees
Which mammography view requires the pectoral muscle on the posterior edge of the breast, retromammary tissue, and the nipple in profile? - ANSWER- Craniocaudal View
An AP left lateral decubitus image is done on a patient that is having a double contrast barium enema. This position best demonstrates what structure(s)? - 1 / 4
pg. 2 ANSWER-When doing a double contrast study the side that has air will be best demonstrated, thus the lateral side of the ascending colon and the medial side of the descending colon will be best demonstrated
In regards to radiographic contrast, what does the term viscosity refer to? - ANSWER-The viscosity of a fluid or contrast is a measure of its thickness (for example, honey has a higher viscosity than water)
What do you do if you accidentally pull a line out of a patient while taking a portable chest x-ray? - ANSWER-Apply pressure to insertion site, call for assistance (nurse), may have to fill out incident report
What grid error has occurred when the image is light on one side and dark on the other? - ANSWER-Off-center, off-focus, or a combination of the two
How many joints are associated with one thoracic spine vertebra? - ANSWER-12 total joints: two superior costal facet joints, two inferior costal facet joints, two superior articular process joints, two inferior articular process joints, two transverse costal facet joints, and two intervertebral disk space joints
True or False: An image that displays vignetting will be dim around the periphery.
- ANSWER-True
What two statistical methods are used with bone densitometry studies? - ANSWER-T-score and Z-score
When is a small bowel follow-through considered to be complete? - ANSWER- When the contrast reaches the cecum (typically takes about 2 hours for a patient with normal intestinal motility)
- / 4
pg. 3 Why is 72" SID necessary for a PA chest x-ray? - ANSWER-Minimize magnification of the heart and to obtain greater recorded detail of the delicate lung structures
What is a Ureterocele? - ANSWER-A cystic dilation (outpouching or ballooning) of the distal ureter near its insertion into the urinary bladder
What pathologies are observed on the below CT slice from an abdominal scan? - ANSWER-A renal calculus is represented by the white arrow on the image and the left kidney is demonstrating signs of Hydronephrosis (dilation of the renal pelvis and calyces caused by an obstruction)
True or False: For all CT imaging of the spine, the patient enters the gantry feet first. - ANSWER-False- the patient will enter the gantry head first for C-spine imaging and feet first for T- & L- spines
An ER stretcher patient's leg is medially rotated 15 degrees; the leg cannot be moved. Do you angle the tube 30 degrees medially or laterally to open up the proximal tibia articulation? - ANSWER-Medially
True or False: An 18 gauge needle is larger than a 24 gauge needle. - ANSWER-
True, the smaller the gauge the larger the needle
What cranial bones are best demonstrated on the 15-degree occipitofrontal projection? - ANSWER-Frontal Bone
What are the names of the two flexures of the large intestine? - ANSWER-Left Colic Flexure (Splenic Flexure) and the Right Colic Flexure (Hepatic Flexure)
- / 4
pg. 4 When doing an axiolateral mandible what side is best demonstrated? - ANSWER- The side that is closest to the IR will be best demonstrated while the side furthest from the board will be projected superiorly
What is the difference in angle between the OML and IOML for a skull image? - ANSWER-About 7 degrees
When doing an axiolateral temporomandibular articulation image, what side is best demonstrated? - ANSWER-The side closest to the IR will be best demonstrated while the side furthest from the board will be projected inferiorly
A patient arrives to your department on spinal precautions and needs a lateral image done for orbits. What cranial structure would you use to assess if you had
any tilt or rotation on your image? - ANSWER-Tilt: ensure the superior orbital
margin of the left and right sides are superimposed
Rotation: ensure that the left and right zygomatic processes of the maxilla are
superimposed
Which exam has the highest gonadal dose: L-spine, BE, Abdomen Image, Upper
GI? - ANSWER-Barium Enema
Is Entrance Skin Exposure the same as absorbed dose? - ANSWER-No:
Entrance Skin Exposure= quantity of radiation, given in SI units of coulombs per kilogram or traditional units of Roentgens, incident upon an object (excluding backscatter radiation)
