Question

20. Briefly describe the significance of the invention of the transistor and microprocessor to the advancement of nuclear medicine. If the next generation of nuclear medicine incorporates "nanoprocessors" and has unlimited storage capability in cloud systems) what do you imagine this would be like? 21. What is meant by the "oxygen enhancement ratio" as a factor that affects the radio sensitivity of tissues or cells to ionizing radiation? What do the terms "radiosensitizer" and "radioprotector" mean with respect to the effects that chemicals may have on cell and tissue ionizing radiation effects?

Answer 1

20) Significant of investion of transistor and microprocessor in nuclear medicine are as follow:-

- Helps to provide sufficient diagnostic information which ultimately hepls in better management,ttreatment and prevention of serious diseases.

-Plays an important role in nuclear medicine imagine procedure often identify abnormalities very early in the prognosis of a disease long before some medical problems are apparent with other diagnosis test.This early detection allows a disease to be early on its course when there may be a better prognosis.

-It is easier to manage a complex diagnosis for a patient who may be suffering from several disease or condition simultaneously.

Feature of nanoprocessossser in nuclear medicine:-

--It can improve diagnostic imaging techniques even at the level of single cells before overall symptoms appears.

-Multimodality imaging using nanoparticles may have better intrinsic and extrinsic resolution and higher accuracy.

21) Oxygen enhacemeenh ration :-

It is enhancement of therapeutic or detrimental effects of ionizing radiation due to the presence of oxygen.

Radiosensitizer:-

It is an agent that make tumor cells more sensitive to radiation therapy.

Radioprotector:-

They are compounds that are designed to reduce the damage in normal tissue caused by radiation .They are basically antioxidants in nature.
