Skeletal In children it is common to perform multiple planar acquisition, rather than whole-body images, because... Camera is far away from the child during acquisition Children are more likely to move during acquisition SNR is higher in multiple planar acquisition Count rate is higher in multiple planar acquisition None 2. Cardiology A two-dimensional illustration of a three-dimensional allocation of the radiotracer in the myocardium which allows visualization of perfusion defects in a compressed format is known as: Counts profile Short axis display Polar map Volume curve None 3. Skeletal There is only one substitute technique for visualization of bone remodeling activity and that is Fluorine-18 Fluciclovine Fluorine-18 Flortaucipir Fluorine-18 Sodium Fluoride Fluorine-18 Florbetaben None 4. Skeletal In bone scan, the recommended scanning speed for whole-body delayed acquisitions is? 1 to 1.5 cm per minute 10 to 15 cm per hour 10 to 15 cm per minute 1 to 1.5 cm per hour None 5. Cardiology More than a few of the main imaging modalities use ionizing radiation for cardiovascular diagnosis and/or treatment. Which of the following modalities is used for coronary artery plaque and calcification imaging? Myocardial Perfusion Imaging (SPECT MPI). X-ray Fluoroscopy. Cardiac Computerized Tomography (CCT). Cardiac Positron Emission Tomography (PET). None 6. Cardiology What does Cardiomegaly mean? Coronary artery disease Cardiac enlargement Myocardial infarction Congestive heart failure None 7. Cardiology Which of the following arteries supplies the myocardium? Carotid Pulmonary Coronary Subclavian None 8. Skeletal Which of the following terms best describes an abnormal lateral curvature of the spine? Sclerosis Lordosis Scoliosis Kyphosis None 9. Cardiology Myocardial ischemia could be distinguished from myocardial infarction by analysis of PET images of the perfusion tracer N-13-labeled ammonia and the glucose analogue FDG. Region with “flow-metabolism mismatch” – decreased flow with normal increased FDG activity – represents: Infarcted myocardium. Viable myocardium. Stunned myocardium. Hibernating myocardium. None 10. Cardiology If a patient has an irregular heart rate, the total number of cardiac cycles acquired for each projection will be the same if each projection is acquired for: The same number of beats The same number of counts The same length of time The same acceptance window None 1 out of 10 Time's upTime is Up! بواسطة ناصر المطيري|2021-09-30T13:08:23+03:00سبتمبر 30th, 2021|لا توجد تعليقات شارك هذه الصفحة, واترك رأيك حول الموضوع باستخدام وسيلة التواصل التي تناسبك FacebookXLinkedInWhatsAppPinterestEmail عن: ناصر المطيري كبير أخصائيي الطب النووي في مستشفى حفر الباطن المركزي و مؤسس موقع نيوكليرمد. اضف تعليقا إلغاء الردتعليق Δ
