The blank scan is performed daily on Positron Emission Tomography (PET) scanners using a Ge-68 transmission source. The term blank scan reflects: The absence of patient. The absence of any material in the field of view (FOV). The absence of technologist. The absence of emission data. None 2. Well Counter (WC) and Uptake Probe (UP) are two detectors commonly configured to a single computer. Which of the following statements describing their properties is INCORRECT? They are solid sodium iodide crystal detectors. WC counts activity within the patient, UP counts patient samples. They measure activity in units of counts or counts per minute. WC counts patient samples, UP counts activity within the patient. None 3. If generator elute contains 635 mCi of Tc-99m, what is the maximum amount of Mo-99 allowed? (0.15 uCi Mo-99 per mCi Tc-99m) 64.2 uCi 0.54 uCi 95.3 uCi 0.15 mCi None 4. The quality control procedure performed on the dose calibrator with all the dose configurations used in the nuclear medicine department is called: Geometry Accuracy Linearity Constancy None 5. The daily quality control for dose calibrator includes a constancy check typically performed with small amounts of Cobalt-57 or Cesium-137. Cs-137 has a half-life of 30 years and produces: 662 keV gamma ray 637 keV gamma ray 388 keV gamma ray 133 keV gamma ray None 6. Well-counter calibration data of a positron emission tomography (PET) scanner are applied for: Attenuation correction. Standardized uptake value (SUV) calculation. Energy window calibrations. Image reconstruction. None 7. If expected value of the long-lived source is 120 mCi and actual reading obtained from dose calibrator is 122 mCi, what is the percentage error of that reading? - 1.7 + 1.7 + 2.0 - 2.0 None 8. All of the following quality control (QC) tests are performed in nuclear medicine department to assess the reproducibility of radiation counter EXCEPT: The relative error The reliability factor The constancy test The chi-squared test None 9. All of the following single photon emission computed tomography (SPECT) quality control procedures can be performed by the technologist EXCEPT: SPECT phantom Uniformity correction matrix Center of rotation (COR) calibration Multiple head registration (MHR) validation None 10. When performing daily intrinsic floods, a point source of Tc-99m is placed five crystal dimensions away and centered over the detector. A point source should produce a measured counting rate not greater than: 15,000 cps 35,000 cps 25,000 cps 5,000 cps None 1 out of 10 Time's upTime is Up! بواسطة ناصر المطيري|2021-03-25T11:27:42+03:00مارس 25th, 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
