Nuc Med Old Qs

Fill in the blanks 1) the syunnonyms for radilonuclide imaging include isotope imaging, scintigraphy , nuclear scaning,isotope scanning , gamma scinti graphy, 2) there are three kinds of radiation gamma rays particle can be detected by SPECT . The most widely used isotope in the nuclear medicine is tecnitium -99 . B-rays particle can be used to treat disease . For eg I-131 can be used to treat hypothyroidism . 3) the main radiopharmacuitals of cerebral oerfusion imaging are TC 99m HMPAQ TC 99m ECD I 123 IMP >they cant cross the intact blood brain barrier During the ictal phase of epilepsy the characters of ceisures focus on cerebral perfusion imaging is hyper perfusion of affected temporal lobe .The clinical application of cerebral perfusion imaging include epilepsy , transient ischemic attack, acute CNS ischmia /infraction , brain death and so on 4) In thyroid imaging ,we can find several kinds of nodules ,which include hot nodules , cold nodules ........... . we can use I-123 , - I-131 and Tc -99m to image thyroid 5) with the equillibrium multigated pool imaging we can obtain the quantitative measuremnet of cardiac function include ejection fraction , peak emptying rate , peak filling rate .Wall motion charactersutics of Aneurysin with this examination is obscure 6) We can usually find randomly distributed hot spots on imaging of patient with metasstatuc disease 7) On the liver colloid imaging if there is a cold spot we can make a diagnosis hemoangioma and cold spot can be found on the patient with abses , malignant tumour , cysts ,avascular liver lesion etc

multiple choice 1) which of the following are the contents of nuclear medicine ? (A) nuclide imaging (B) radio immuniassay (c) CT abd MRI (d) treatment of hypothyroidism with 131-I 2) which of the following are isotopes of 131-I ans - (a) 123-I 3) which of the following is isomer of isotope 99m -Tc ans (c) 99-TC 4) which one of the following is the unit of radio activity ans (a) mCi 5) to take dynamic reanl imaging which statement is in correct ans (a) using slow transiting radiolableled tracer we can take dynamic reanl imaging 6) indications of dynamic renal imaging include ....................................... 7) to diagnose hemaangioma which state ment ius correct ans (b) there is cold spot on colloid liver and hot spot in liver blood pool imaging 8) abnormal radioactivity distribution on bone imaging includes (a) hot spots (B) cold spots

(c) hot spots outside of bone (D0cold spots outside of bone

9 ) the clinical use of scan includes

ans (A) metabollic bone disease 10) On V/Q scaning the characteristics of pulmonary embolism is ans (a) normal ventillation and decreased or basent perfusion normal perfusion and decreased or absent ventillation

long question (10 X 4 ) 1) how many radio nuclide technique have gained widely clinical acceptance ? which technique are used for patient in rest/exercise ? why it is performed in patient in exercise? 2) what is reversible ischemic ? what is irreversible infraction? what are the clinical applications of myo cardila perfusion? 3) why we use 131_ Iodine to treat hypothyroidism ? what is hot nodule ? 4) please detail thr main principal of competitive binding reaction of radia ammini assay ?
