- What is nuclear medicine? According to Merriam-Webster
dictionary nuclear medicine is a branch of medicine dealing with
the use of radioactive materials in the diagnosis and treatment of
disease

- MIBG When a CT scan doesnt give a definite answer, a MIBG scan
is used Idoine-131 is injected through your vein, and then later
you go through a scan. The scan can take up to 1-2 hours, and may
take several days to complete. The MIBG can locate
neuroblastoma.
- Slide 5
- What are the types of nuclear medicine? Bone scan PET Scan
Gallium scan MIBG Scan CT Scan
- Slide 6
- What elements are involved in these scans? Iodine-131 This
isotope of Iodine is used to help cancers in your thyroid gland.
The thyroid gland takes iodine on a regular basis to help it
function. The physician puts a small amount of this radioactive
material to help kill the damaged cells. Coblat-60 Coblat-60 helps
to treat brain tumors with minimal damage to the surrounding
tissues. Gama Knife uses cobalt-60 to shoot this radiation into the
specific targets of the brain to destroy the tumor. Strortium-89
This type of radiation focuses on the deeper tumors found inside
the body. If the physician needs to pass radiation through health
tissue, such as a bone tumor, they would probably use strortium-89
as it will reach the targeted tumor and neutralize it without
effecting the healthy tissue too much.

- CT Scans British engineer Sir Godfrey Hounsfield and Dr. Alan
Cormack discovered the CT scan First used in 1974. Used because can
quickly give an accurate cross-sectional image of what the doctor
wants to see. Commonly used to identify injuries to the lungs,
heart and vessels, liver, spleen, kidneys, bowel, head or other
internal organs in cases of trauma.

- Radiologist Radiologist are medical doctors who specialize in
reading and understanding the images provide from the scans, and
how to diagnose what they see, and how to treat it. A key factor to
becoming a Radiologist is being excellent in Chemistry and other
mathematic classes. Schooling is long and rigors but it pays off.
The median salary is $382,129 a year. 1. 4 year bachelor degree,
typically in a science major like chemistry 2. Take MCAT to get
accepted into medical school. 3. 4 year medical school. 4. Complete
a residency in Radiology 5. May choose to do a fellowship in
Radiology, about 1-2 years 6. Take the board exam to become a
Radiologist.

- What are the risks? Depending on how much exposure youve
received and where youve received the radiation will determine the
risk involved. If exposed to the head, can result in loss of hair
To abdomen, results in vomiting To chest, results in shortness of
breath, or difficulty swallowing.
- Slide 11
- Summary Different scans shows different images of the body.
Depending on what needs to be seen the Radiologist will order for a
specific scan. This radiologist understands about diagnosing and
treating what he/she sees from the images provide. There are many
aspects of chemistry involved including different types of elements
to trace certain diseases.
