NUCLEAR MEDICINE BOARD REVIEW EXAM QUESTIONS AND VERIFIED SOLUTIONS 2024 LATEST GUIDE GRADED A+. 2 / 14 1. Gas Ventilation: Xe 133, 81 KeV, 5.3 half life; reactor produceddose: 10-20 mCi imaging: posterior position negative pressure room required uses activated charcoal trap to accumulate the exhaled xenon gas until decayed tobackground single breath: during inhalation wash in / equilibrium : collected while the xenon distributes through aerated portionsof the lung wash out : while radioactivity is cleared from lungs 2. Sr 89 Chloride: Strontium Chloride, Metastron 1.46 MeV max, .58 Mev meanhalf life = 50.5 days 40-60 uci/kg IV for skeletal mets, depresses bone marrow shouldn't be used if leukocyte count below 2400/ul or platelet below 60,o00/ulexcretion : urinary 3. I 131Tositumomab: Bexxarhalf life = 8.04 days 606.3 KeV max energy treatment of patients with NHL before treatment, patient must receive 650 mg acetaminophen and 50mg diphy-dramine orally thyroid uptake should be minimized with SSKI activity initially seen in blood pool, liver and spleen later times, activity in liver, spleen, thyroid, bladder, and tumor sites 4. Y 90 ibritumomab tiuxtetan: Zevalinhalf life = 2.67 days 2.281 MeV treatment of patients with NHL (disseminated follicular B-Cell)monoclonal antibody against lymphoma antigens before treatment, patient must receive 650 mg (imaging) acetaminophen and 50mgdiphydramine orally max dose = 32 mci 3 / 14 platelets must be at least 100,000/mm3 5. Sm 153 EDTMP: ethylenediaminetetra methylene phosphonicQuadramet half life = 46.7 hours 0.81 MeV maximum 4 / 14 concentrates in bone marrow for patients with more metabolically activate metastases from prostate or breastcancer, as well as those from osteogenic sarcoma 1.0mci/kg urinary excretion 6. Bone therapy blood requirements: 60,000-100,000/ul platelet/ul leukocyte 2000/ul granuolyte 7.
