A vial of 99m Tc MDP has a concentration of 45 mCi/ml at 9 am. A 20 mCi dosage is needed for 11 am. What volume of this radiopharmaceutical is needed for dosing? a. 0.44 ml b. 0.56 ml c. 1.8 ml d. 2.3 ml

Answer 1

191:Rose Bengal is used in hepatobiliary scan or imaging

Orthoiodohippurate is used in the imaging of renal system

Tge fibrinogem is used in the imaging of deep vein thrombosis

Iodocholestrol is used in the imaging of adrenal gland

Ans:d.iodocholestrol

192.The radionucleid agent will be injected into the vein ,then it passes through the arteries of the renal system .Now the arteries can be seen.Along with this thr size and location of the kidney can be seen,it has to drain out do the filtering formation can be seen.The radionucleid completely eliminates from the body in about a day

Ans:a.arterial perfusion of the kidney

193.Dead time refers to absence of recording by the system or system cannot record

S phase is the radio resistant phase

Inactivation phase refers to exposure but no symptoms have occurred

Latent phase is the symptoms experienced for about 2 to 3 weeks.Here the symptoms are often hidden.

Ans:Latent phase

194The formation of z pulse in the electronic device is possible when there is a X and Y circuit.They are in proportional with kinetic energy.To this to be possible a summing circuit is necessary .This collects the pulse from the preamplifier.The output pulse are delivered by anticoincidence circuit

Ans:b.summation circuit
