Diagnostic imaging test UPDATED ACTUAL
Exam Questions and CORRECT Answers
X-Ray allows for view of only what type of tissue well? - CORRECT ANSWER - bone
When can X-Rays be useful? - CORRECT ANSWER - detecting fractures of skull and
vertebrae, and abnormal structures
T/F: Different tissues absorb different amounts of radiation - CORRECT ANSWER - true
What absorbs the most radiation? What color does it appear? - CORRECT ANSWER -
calcium, white
CT images what bodily structures? - CORRECT ANSWER - bone and soft tissue
What image test uses x-ray images in a tube that travels around the patient to obtain "slices"? -
CORRECT ANSWER - Computerized Tomography (CT)
When can a CT be useful? - CORRECT ANSWER - diagnosis of hemorrhage, tumors,
tissue trauma, dementia
What imaging device is precise, sensitive, fast and can use contrast dye for a clearer image? -
CORRECT ANSWER - Computerized Tomography (CT)
MRI produces high/low contrast of soft tissue? - CORRECT ANSWER - high
When can an MRI be useful? - CORRECT ANSWER - diagnosis of brain and spinal cord
lesions: stroke, tumor, trauma, dementia, multiple sclerosis & infections
, T/F: MRIs used radiation - CORRECT ANSWER - false
When is MRI contraindicated? Why? - CORRECT ANSWER - over metal implants due to
magnetic fields
What are the 2 types of weights for MRI? - CORRECT ANSWER - T1 and T2
How does CSF appear in T1 weighted MRIs? - CORRECT ANSWER - dark
How does CSF appear in T2 weighted MRIs? - CORRECT ANSWER - bright
How does inflammation appear in T1 weighted MRIs? - CORRECT ANSWER - dark
How does inflammation appear in T2 weighted MRIs? - CORRECT ANSWER - bright
What 3rd commonly used MRI weight is similar to a T2-weighted whereas abnormalities remain
bright, but normal CSF fluid is attenuated and made dark? - CORRECT ANSWER - Fluid
Attenuated Inversion Recovery (Flair)
What are Fluid Attenuated Inversion Recovery (Flair) MRIs sensitive to? - CORRECT
ANSWER - pathology (makes the differentiation between CSF and an abnormality much
easier)
