9 Respiratory System Scintigraphy 9331) Ventilation images are usually performed:a. with the patient supine so that perfusion is relativelyuniform throughout the lungsb. anteriorly, because more emboli occur anteriorly thanposteriorlyc. posteriorly to reduce soft tissue attenuation anddecrease distance to detectord. with the patient erect, so that perfusion is relativelyuniform throughout the lungs32) The use of a nebulizer is required with which of thefollowing radiopharmaceuticals during lung imaging?a. 99m Tc DTPAb. 99m Tc MAAc. 127 Xed. 133 Xee. all of the above except b33) Perfusion and ventilation lung imaging removesthe need for a chest x-ray.a. trueb. false34) When performing a V/Q lung study with 99m Tc MAA and133 Xe, which portion of the exam should be performedfirst?a. ventilationb. perfusionc. either may be performed firstd. they may be performed simultaneously35) Trapping systems for 133 Xe should be installed at thelevel of the , because 133 Xe is than air.a. ceiling, heavierb. ceiling, lighterc. floor, heavierd. floor, lighter
949 Respiratory System Scintigraphy36) Stomach visualization on a ventilation scan performedusing 99m Tc DTPA aerosol indicates:a. there was turbulent air flowb. the nebulizer is not functioning properlyc. the patient is a smokerd. the patient swallowed some of the radiopharmaceuticale. the patient has a right to left cardiac shunt37) The radiopharmaceutical used for ventilation scanningwith the highest administered dose is:a. 133 Xe gasb. 99m Tc DTPA aerosolc. 127 Xe gasd. 81m Kre. 99m Tc MAA38) Only half of the administered dose of 99m Tc DTPAaerosol is delivered to the patient.a. trueb. false39) Patient education prior to a ventilation scan may:a. improve image qualityb. relax the patient and thereby speed washoutc. reduce the radiation dose to the technologistd. all of the abovee. a and c only40) The liver may be seen in the washout phase of aventilation study because:a. 99m Tc DTPA aerosol was swallowed and then enteredthe bloodstream via the stomachb. 133 Xe gas is fat solublec. particle size is too smalld. air flow is turbulent
