Static bone imaging is routinely performed how long after tracer administration to an adult: A)30min B)1hr C)2-3hr D)24hr C)2-3hr. Static bone imaging performed with a labeled diphosphonate compound is routinely performed 2-3hr after tracer administration. Which of the following structures normally appear as areas of increased activity on the bone images of adults: A)anterior iliac crests B)glenoid fossa C)sternoclavicular joints D)all of the above D)all the above. On bone images of adults, areas of normally increased tracer activity include all those listed as well as the sacroiliac, hip, and acromioclavicular joints and vertebral column. Which of the following conditions is visualized on a bone image as a photopenic area: A)attenuation B)tracer infiltration C)acute myocardial infarction D)osteomyelitis A)attenuation. A photopenic area is one in which a smaller number of photons is visualized-a cold spot. A material that absorbs photons may cause an attenuation artifact, an area of falsely decreased tracer concentration(jewelry, belt buckles, pacemaker) It is safe to block a portion of the pulmonary circulation with MAA particles in patients with suspected PE because: A)# of injected particles block only a small number of precapillary arterioles B)particles are made from albumin isolated from human serum TestTrackers: Unlock Your Exam Potential! | Quality Practice Materials | Boost Your Confidence Today! | Thank You for Choosing Us! © 2024 TestTrackers Customer Support: [] Resources & Updates: [Testtrackers - Stuvia US] Your Success is Our Mission! A)# of injected particles blocks only a small number of precapillary arterioles. Less than 1% of the precapillary arterioles are blocked with the MAA particles; therefore, there is no adverse effect on the patient. A nebulizer is used to administer which of the following lung ventilation radiopharmaceuticals: A)81mKr gas B)133Xe gas C)99mTc-pentetate D)99mTc-MAA C)99mTc-pentetate. A nebulizer is a device that uses ultrasound or pressure to create airborne (aerosol) particles from a liquid. Which of the following radiopharmaceuticals may be used to image acute deep vein thrombosis in the lower extremities: A)99mTc-MAA B)99mTc-arcitumomab C)131I-iobenguane D)111In-oxyquinoline A)99mTc-MAA is used to image acute deep-vein thrombosis in the lower extremities. In performing radionuclide venography with 99mTc-MAA, the radiopharmaceutical is administered at what site: A)antecubital of either arm B)either femoral vein C)dorsal veins on top of each foot D)either basilic vein C)dorsal vein on to of each foot. The tracer is introduced into the deep venous system of the legs. Therefore, the tracer is administered into the dorsal vein of each foot. After total thyroidectomy, total-body imaging with radioiodine normally will demonstrate tracer concentration in which areas: A)liver, lungs, bones B)salivary glands, stomach, and bladder C)liver, salivary glands, stomach, lungs D)bladder, liver, brain TestTrackers: Unlock Your Exam Potential! | Quality Practice Materials | Boost Your Confidence Today! | Thank You for Choosing Us! © 2024 TestTrackers Customer Support: [] Resources & Updates: [Testtrackers - Stuvia US] Your Success is Our Mission! B) The salivary glands and saliva in the mouth, the gastric mucosa and secretions into the intestine, and the urinary bladder are sites that normally concentrate radioiodine. Concentrations in other sites indicate areas of functioning thyroid metastases. A parathyroid adenoma will concentrate which of the following radioparmaceuticals: A)123Isodium iodide B)99mTc-pertechnetate C)99mTc-sestamibi D)99mTc-pertechnetate or 99mTcsestamibi C)99mTc-sestamibi When positioning a patient for an LAO view of a gated equilibrium ventricular function study, tilting the camera toward the patient's feet separates what two structures: A)left ventricle and aorta B)left ventricle and left atrium C)left and right atria B)left ventricle and left atrium. The left atrium is partially hidden by the aorta and pulmonary artery. Tilting the detector caudally visually brings the left atrium out from under these structures and separates it from the left ventricle. Which tracer is excreted primarily via the hepatobiliary system: A)99mTc-sestamibi B)99mTcexametazime C)99mTc-medronate D)201Tl-thallous chloride A)99mTc-sestamibi A cardiac stress test requires the placement of how many electrodes on the patient's body: A)3 B)6 C)10 D)12 C)10. A cardiac stress test requires a 12-lead ECG tracing, which uses 10 electrodes attached to the patient. 2 arm, 2 leg, and 6 chest leads.

Visualization of bone marrow uptake on a 99mTc-sulfer colloid liver/spleen image is most likely the result of: A)improper colloid particle size B)insufficient tracer circulation time C)liver dysfunction D)overactive bone marrow C)liver dysfunction. Bone marrow uptake is visualized on liver/spleen images when severe liver dysfunction, such as advanced cirrhosis, is present. During hepatobiliary imaging, which structure will NOT be visualized if cystic duct obstruction is present: A)common hepatic duct B)common bile duct C)gallbladder D)small intestine C)gallbladder. If cystic duct obstruction is present, the tracer will be unable to enter the gallbladder. The cystic duct is the passage between the common bile duct and the gallbladder. How long after the administration of 99mTc-pertechnetate does imaging begin for the localization of a Meckel's diverticulum: A)immediately B)15-20min C)1hr D)2-3hr A)immediately. For localization of a Meckel's diverticulum, imaging begins immediately after administration of
