Nuclear
Engineering focuses on solving several of the world's most important
grand-challenge problems. The last three years have seen much happen
for Nuclear Engineering.
Nuclear Engineering is all about devising
how to use radioactive materials in manufacturing, agriculture, medicine, power
generation, and many other ways, perhaps the most important being in medicine,
where over 1/3 of all procedures in the United States use nuclear techniques.
In nuclear medicine, small amounts of
radioactive materials called radiopharmaceuticals are used for diagnosis and therapy. Radiopharmaceuticals are medicinal products
that are radioactive when used in patients. They are used in specialised
hospital departments, primarily for diagnostic purposes. Nuclear processes are
used to provide images inside the human body, to detect and measure biochemical
processes, and to provide therapy. The radiation from the radiopharmaceutical
makes it possible to photograph the distribution of the medicinal product
throughout the body. The radiation is usually very low, lower than the level of
radiation from X-ray investigations.
A major event in 2000
was the FDA approval of the first Monte-Carlo code for use by doctors to design
radiation therapy for cancer. Based on nuclear reactor design methods, this new
tool now allows doctors to take detailed magnetic resonance imaging data
(another nuclear technique) and predict with great accuracy how to deposit
precisely enough radiation to kill cancer tumours without damaging surrounding
tissue. Previous crude calculation methods often forced doctors to cause damage
to substantial amounts of healthy tissue, or to miss completely killing tumours.
The use of
radiopharmaceuticals
is expected to increase rapidly as new diagnostic methods are developed. Nuclear medicine
is being considered for use in infection imaging, neurology and other fields.
At this time, most therapeutic radiopharmaceuticals
involve the treatment of cancer. On-going research is being conducted to expand
nuclear
medicines to treat other diseases as well.
Nuclear
diagnostic testing can be performed on almost every organ of the body. There
are currently over 100 nuclear medical exams, with more being developed. Some
of these include brain scans, bone scans, cardiac stress tests and thyroid
studies. Prior to the test, the radiopharmaceutical is administered to the
patient orally, intravenously, or by inhalation. The radioactive material is
short-lived, and either converts to a non-radioactive substance, or passes
quickly through the body.
Advancements in
nuclear medicine technology is expected to represent a key strategic factor in
opening up new clinical opportunities for radiopharmaceutical agents. Growth in
Radiopharmaceuticals market
will be based on the development of new products, and robust demand for
cardiology procedures, sales of oncology products, in particular, FDG for PET imaging.
Establishment as well as expansion of FDG-PET reimbursement to all cancer types
and also for non-oncology applications is expected to further boost the demand
for radiopharmaceuticals.
