Question no. 1:
Nuclear medicine producers involve the usage of radioactive elements, also known as radiopharmaceuticals, that aids in locating and treating the disease. A small dose of radiotracers is generally swallowed, inhaled in the form of gas, or infused into the bloodstream. Most of the time, these radiotracers give off their energy in the form of “gamma rays”, which are detected by special sensors, known as gamma detectors CITATION DrC17 \l 2057 (Dr. Cain, 2017). The healthcare worker identifies different conditions, such as hematomas and tumors, by judging the behavior of the radiotracer in the body through the scan.
Question no. 2:
Different type of set of instructions is provided to patients of different conditions. However, here are some of the common preparations in all the procedures.
* During the procedure, the patient is asked to wear a gown.
* Inform the doctor about any medication (herbal or vitamins) that the patient is taking, recent illness, or any sort of allergies.
* Metallic items or jewelry are removed before starting the procedure.
* Women need to inform their doctor if they are pregnant or breastfeeding.
* Different types of scans have various guidelines, such as no eating or drinking a few hours before the exam or no caffeine products.
Question no. 3:
Before the emergence of this specialized field in radiology, it was very difficult for physicians to locate and diagnose various ailments, but nuclear medicine has provided a new ray of hope to cure different illnesses. However, it has its advantages and limitations that are discussed below.
Advantages:
* It helps to get the images of internal organs that can hardly be seen otherwise. This is achieved by using techniques such as tomography or three-phase scanning that are not just efficient, but also safe CITATION Jim15 \l 2057 (Jimenez MD, 2015).
* Malignant and benign tumors can be detected via PET scan, thus saving the patient from more expensive and serious surgery.
* One of the best advantages of nuclear medicine is its accuracy due to which many complex procedures have been turned into simpler ones.
Limitations:
* The radiation used in nuclear medicine can be extremely harmful to pregnant women and aged patients.
* Despite the fact that it provides accuracy, there is still a doubt in the complete cure of the illness.
* There could be allergic reactions in response to radiopharmaceuticals. However, this is very rare and moderate.
The advantages of nuclear medicine are far more than its limitations, as a very small amount of radioactive element is used and the risk is very low when compared to its blessings.
Question no. 4:
Nuclear medicine treatment uses radiopharmaceuticals to draw attention to internal organs and veins. It is used for the diagnosis and treatment of several diseases such as cancer, metabolic disorders, the diseases of heart and gall bladder, helps to diagnose various brain conditions such as Alzheimer’s and dementia CITATION Bra17 \l 2057 (Brazier, 2017).
Question no. 5:
Applications of Nuclear Medicine in MRI:
* Radiation is used in nuclear medicine to get the image of the place to detect the disease and this is also the basic principle of MRI.
* In order to produce a vivid image of the internal organs, radioactive material is infused in the blood in nuclear medicine. However, to produce a clear and high-quality image, magnetic fields (strong) and radio waves are utilized in MRI.
* In nuclear medicine, radiotracers are put into the body either
