a Bronchioles b Lungs c Bronchial tree d Alveoli 17 The aerosol is generated from an ultrasonic nebulizer or a positive pressure nebulizer; it is inhaled through a mouthpiece or facemask. a True b False 18 What is the biggest concern during a DTPA ventilation study. a Technologist can get contaminated from dose b Patient can spit out radioactive material causing contamination on their chest c Difficulty in obtaining accurate images due to patient movement d Risk of allergic reaction to the radiotracer 19 What is the Dose for a DTPA radio aerosol ventilation study? a 35 mCi b 20 mCi c 25-40 mCi d 10-15 mCi 20 How much of the Dose for a DTPA radio aerosol ventilation study gets to the patient? a 35 mCi b 20 mCi c 25-40 mCi d 10-15 mCi 21 During a DTPA Ventilation study what diseases show little or no peripheral distribution? a Bronchitis b Severe Bronchial Asthma c Cystic fibrosis d Mild Asthma 22 Less central and patchy peripheral filling tends to be seen in ______ for DTPA ventilation studies? a Mild Asthma b Chronic Bronchitis c Cystic Fibrosis d All of these e None of these 23 Smokers have slower removal of tracer activity then nonsmokers. a True b False 24 Abnormal perfusion and Normal ventilation means? a PE b Pneumonia c COPD d Emphysema e Chronic bronchitis f Asthma 25 Abnormal perfusion and Abnormal ventilation means? a All of these b None of these c COPD d Emphysema e Chronic bronchitis f Asthma 26 Chronic Bronchitis and Emphysema have a variety of defects in blood flow and ventilation a True b False 27 In Chronic bronchitis? a Ventilation much worse than blood flow, and some changes in the pattern of ventilation and blood flow is visible as disease gets worse b The defects in ventilation and blood flow match up more closely and tend to remain the same over time c V/Q scan can be used to establish individual lung function when pneumonectomy is planned d Calculation of lung function; technologist draws ROI using NM computer to analyze counts in vent and/or perfusion images; can be used to determine lung function and for donors of lung tissue 28 In Emphysema? a Ventilation much worse than blood flow, and some changes in the pattern of ventilation and blood flow is visible as disease gets worse b The defects in ventilation and blood flow match up more closely and tend to remain the same over time c V/Q scan can be used to establish individual lung function when pneumonectomy is planned d Calculation of lung function; technologist draws ROI using NM computer to analyze counts in vent and/or perfusion images; can be used to determine lung function and for donors of lung tissue 29 In Primary Lung cancer? a Ventilation much worse than blood flow, and some changes in the pattern of ventilation and blood flow is visible as disease gets worse b The defects in ventilation and blood flow match up more closely and tend to remain the same over time c V/Q scan can be used to establish individual lung function when pneumonectomy is planned d Calculation of lung function; technologist draws ROI using NM computer to analyze counts in vent and/or perfusion images; can be used to determine lung function and for donors of lung tissue 30 In Quantitative VQ scan? a Ventilation much worse than blood flow, and some changes in the pattern of ventilation and blood flow is visible as disease gets worse b The defects in ventilation and blood flow match up more closely and tend to remain the same over time c V/Q scan can be used to establish individual lung function when pneumonectomy is planned d Calculation of lung function; technologist draws ROI using NM computer to analyze counts in vent and/or perfusion images; can be used to determine lung function and for donors of lung tissue 31 What is Stripe sign? a Thin line or stripe of activity which indicated perfused lung tissue between a perfusion defect and the adjacent pleural surface b Perfusion defects which correlate to interlobal pulmonary fissures, both major and minor c Accumulation of fluid in the alveoli and interstitial spaces of the lungs d Fluid accumulation in body cavities due to increased vascular permeability 32 What is Fissure sign? a Thin line or stripe of activity which indicated perfused lung tissue between a perfusion defect and the adjacent pleural surface b Perfusion defects which correlate to interlobal pulmonary fissures, both major and minor c Accumulation of fluid in the alveoli and interstitial spaces of the lungs d Fluid accumulation in body cavities due to increased vascular permeability Feedback 12 2000 mL = 2 L which is the amount it is diluted in. 23 They have faster clearance due to more alveolar membrane permeability.
