Which of the following radionuclides has the highest kinetic energy of the positron? C-11. N-13. Rb-82. F-18. None 2. Radioactive decay is the process by which an unstable atomic nucleus loses energy by emitting ionizing radiation. The emission is described as spontaneous meaning: The nucleus decays after collision with shielding material The nucleus decays after collision with another particle or atom The nucleus decays without collision with another particle or atom The nucleus decays without collision with shielding material None 3. Dual time-point imaging (DTPI) can improve accuracy of positron emission tomography (PET) imaging. DTPI technique is a specialized protocol in which: Two days delay imaging is performed Flow study is performed followed by static imaging Delay imaging is performed Dual-isotope technique is applied None 4. When only image quality is considered, the best possible distance between the collimator and the patient’s body for a gamma-camera equipped with HRES collimator is: Half the collimator diameter 10 cm Contact 1 in None 5. The ratio of net counts in the photopeak to net counts in the entire spectrum is called: Energy constant Energy resolution Photopeak efficiency Photopeak window None 6. Technetium-99m and Technetium-99 are: Isotones Isobars Isotopes Isomers None 7. Elements with same atomic number and different atomic mass number are called? Isotopes Isotones Isomers Isobars None 8. The minimum amount of energy needed to overcome the forces holding the atom together is called: Binding energy Kinetic energy Holding energy Thermal energy None 9. The nucleus is composed of two types of particles called: Quarks and protons Electrons and quarks Protons and electrons Neutrons and protons None 10. Image representation of raw data obtained from projections of the object for image reconstruction is called: Blank scan Star artifact Sinogram Uniformity projections None 1 out of 10 Time's upTime is Up! بواسطة ناصر المطيري|2021-09-20T14:26:04+03:00أبريل 15th, 2021|معلومات عامة|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. منشورات متعلقة اختبار: أساسيات الطب النووي اختبار: أساسيات الطب النووي أبريل 15th, 2021 | لا توجد تعليقات اختبار: رعاية المريض اختبار: رعاية المريض مارس 10th, 2021 | لا توجد تعليقات اختبار: الصيدلة النووية اختبار: الصيدلة النووية مارس 10th, 2021 | لا توجد تعليقات اختبار: الإختصارات والمصطلحات الطبية اختبار: الإختصارات والمصطلحات الطبية مارس 8th, 2021 | لا توجد تعليقات اترك تعليقاًإلغاء الرد
