Immunology Images obtained shortly after injection of white blood cells labeled with In-111 or Tc-99m are characterized by intense activity-up to 4 hours, but disappearing prior to 24 hours imaging-pulmonary activity. This phenomenon is caused by the fact that: The pulmonary capillaries have an average diameter bigger than that of neutrophils. The mean driving pressure across the pulmonary circulation is higher than that in the systemic circulation. During the labeling procedure, neutrophils are deformed and became bigger. Activated neutrophils adhere to the pulmonary capillaries for a longer period than do nonactivated neutrophils. None 2. Cardiology What is the way that the blood return to the heart from small intestine? Hepatic portal vein -> Vena cava -> Hepatic vein Hepatic vein -> Vena cava -> Hepatic portal vein Vena cava -> Hepatic portal vein -> Aorta Hepatic portal vein -> Hepatic vein -> Vena cava None 3. Immunology Tc-99m-labeled leukocytes and Tc-99m sulfur colloid accumulate in the reticuloendothelial cells of the bone marrow. The distribution of marrow activity is similar for both radiopharmaceuticals with the exception of an acute or chronic bone infection. Osteomyelitis: Stimulates uptake of sulfur colloid but suppresses uptake of leukocytes. Stimulates uptake of leukocytes but suppresses uptake of sulfur colloid. Stimulates uptake of leukocytes but does not affect uptake of sulfur colloid. Stimulates uptake of sulfur colloid but does not affect uptake of leukocytes. None 4. Skeletal In bone scan, Diffusely increased soft-tissue uptake can be caused by... Drug interference Failed Tc-99m labeling Renal failure or Dehydration Severe osteoporosis 5. Immunology Images obtained shortly after injection of leukocytes labeled with In-111 or Tc-99m are characterized by intense pulmonary activity that clears and approaches background level by: 4 hours after injection. 2 hours after injection. 1 hour after injection. 0.5 hour after injection. None 6. Cardiology The venous blood returning via the superior vena cava (SVC) and inferior vena cava (IVC) enters the heart at the: Left ventricle (LV). Right atrium (RA). Left atrium (LA). Right ventricle (RV). None 7. Respiratory The Collimator used for V/Q scan is: LEAP MEAP Pin-Hole HEAP None 8. Skeletal In children it is common to perform multiple planar acquisition, rather than whole-body images, because... Count rate is higher in multiple planar acquisition Children are more likely to move during acquisition Camera is far away from the child during acquisition SNR is higher in multiple planar acquisition None 9. Immunology Tc-99m and In-111-labeled leukocyte imaging (WBC) are established procedures for diagnosing inflammation and infection. All of the following wounds appear as areas of intense activity on WBC images EXCEPT: Skin grafts wounds. Surgical incision wounds. Tracheostomies wounds. Ileostomies wounds. None 10. Respiratory Which of the following terminology for sensation of breathlessness in recumbent position? Hyperpnoea. Tachypnea. Orthopnea. Oligopnea.
