[Therapy] A lone “cold” nodule in an otherwise normal thyroid gland warrants: Surgical removal. Radiation therapy. Fine needle aspiration biopsy. Chemotherapy. 2. [PET] Before FDG administration, the patient relaxes in a waiting room to minimize muscular activity, and in so doing minimizes any physiological uptake of FDG in the muscles. Hyperventilation may cause increased uptake in the: The diaphragm The peritoneum Leg muscles Arm muscles 3. [Therapy] According to the Society of Nuclear Medicine “SNM Procedure Guideline for Therapy of Thyroid Disease with I-131 (Sodium Iodide),” typically administered activity for treatment of presumed thyroid cancer in the neck or mediastinal lymph nodes is in the range: 200–250 mCi. 150–200 mCi. 100–150 mCi. 50–100 mCi. 4. [Therapy] Which of the following property of radiation is principally used in the treatment of tumors? Photographic effect Chemical effect Biologic effect Fluorescent effect 5. [CNS] Which of the following arteries supply the brain? External carotid and vertebral. Internal carotid and vertebral. Subclavian and common carotid. Brachial and common carotid. 6. [PET] The usefulness of F-18 FDG PET in infection imaging is based on the fact that granulocytes and macrophages in infectious foci: Have high glucose consumption Have high mitotic rate Have high insulin production Have short life span 7. [Therapy] The hematologic toxicity of Y-90 Zevalin therapy is common. All of the following can be a sign of hematologic toxicity EXCEPT: Fever Anemia Arrhythmia Bruising 8. [PET] The elevated serum glucose level at the time of fluorodeoxyglucose (FDG) administration may decrease the sensitivity of the FDG-PET study. Althoguh intravenous bolus of insulin may effectively lower the serum glucose level, however induced hyperinsulinemia will: Shunt glucose to skeletal and cardiac muscles. Decrease heart rate. Induce hyperglycemia. Increase blood pressure. 9. [PET] All of the following cellular mechanisms are responsible for malignant cells increased F-18 fluorodeoxyglucose accumulation EXCEPT: Low mitotic rate. Increased membrane transporters. Low glucose-6-phosphatase. Increased intracellular hexokinase. 10. [CNS] The brain consists of two hemispheres and each hemisphere has four lobes. Which of the following structures is NOT the brain’s composition? The parietal lobe The frontal lobe The temporal lobe The lateral lobe 1 out of 10 Time's upTime is Up!
