Why might it be important to ask the patient if they have had had radiation therapy? because scarring caused by radiation therapy mimics lung disease.
What are the two types of lab results important to CT? 1. renal function 2. blood's ability to coagulate
What are the two tests that determine renal function? BUN and creatinine
What does BUN provide? it provides information about the kidney’s ability to remove impurities from the blood.
What does an elevated BUN indicate the possibility of? renal disease
What is the normal/acceptable range for BUN values? 5 to 25 mg/dl

What are the three tests that determine the bloods ability to coagulate? 1. prothrombin time (PT) 2. partial thromboplastin time (PTT) 3. platelet count

What are the typically accepted values for PT? 10 to 14 seconds
What are the typically accepted values for PTT? 20 to 40 seconds
What are the typically accepted values for platelet count? 150,000/mm³ to 400,000/mm³

rem and Sievert are a measurement of what? effective dose or dose equivalent

The ____ is an indicator of radiation dose which includes the radiation located within the intended slice thickness as well as that from the penumbra. CTDI
The ____ assumes that consecutive slices are contiguous. CTDI
In order to account for gaps or overlaps between adjacent slices there is another indicator of dose called the ____. MSAD
Manufacturers claim that their dose-optimizing software which automatically varies the mA allows for dose reductions ranging from ____% to ____%. 15% to 55%
If a patient is sedated, what type of monitoring device is recommended? pulse oximeter
