Hi,
"For example, the second most commonly used radionuclide is Tc-99m, following the most commonly used radionuclide, F-18 (which is produced by accelerator bombardment of O-18 with protons."
I do NOT agree with this.. for me the most used radionuclide is by far Tc-99m, maybe followed by F-18 — Preceding unsigned comment added by 66.218.148.129 ( talk) 15:36, 9 November 2011 (UTC)
Arguments to that :
1) wikipedia; Article on Tc-99m : Technetium-99m in Nuclear Medicine
Technetium-99m is used in 20 million diagnostic nuclear medical procedures every year.
and
2) Report 280: MARKET FOR PET RADIOPHARMACEUTICALS AND PET IMAGING (from BIO-TECH SYSTEMS inc.):
(link: www.biotechsystems.com/reports/280/default.asp)
The demand for PET continued to grow in 2007 reaching 1.8 million procedures, an increase of 21% for the year. Growth should continue with procedure volume increasing 20% in 2008. By 2015, PET procedure volume should rise to 7.1 million procedures.
3) 90% of all nuclear medicine exams use Tc-99m (my radiopharmacy course!)
NOTE (F-18 is around 90% of PET procedures) so that means that in 2008 there was 10 fold more nuclear medicine procedures using Tc-99m than F-18...
Perhaps you should add some references concerning the number of exams for each radionuclide.
Good luck

Given some of the talk on this page, it seems that this article has been subjected to some vandalism, apparently due to misguided concerns about nuclear energy, nuclear weapons, etc. Maybe the articles could be resticted to editing, or maybe even the title could be changed somehow to avoid attacks of this kind.

"Nuclear Medicine" is the name of this field of medical science. It makes no sense to change the title of the article because of a few nuclear-phobic vandals. Good idea about restricting editing, though. -Rob 5 JAN 2007
There's also been some 6th-grade style vandalism--search for "penis" to find it. They clearly had destroyed some words at the end of the sentence, and I wasn't quite sure what was missing, or I would have just fixed this.

Hi All,
I'm of the opinion that the entire following section should be moved to "Gamma-camera", as this seems to be a specific topic within a broad-titled article. There is already a link within the article for further explanation of a gamma-camera if the reader is interested and wants to explore further.
I'd originally written this to be a layperson's article, without wishing to delve too deeply into instrumentation, nuclear physics, physiology, etc. under this title.
Opinions? Comments? If I don't hear any objections, I'll move that slab to gamma-camera.
- Adam
Proposing to move this:
Traditionally, gamma-cameras have consisted of a gamma-ray detector, such as a single large sodium iodide scintilation crystal, coupled with an imaging sub-system such as an array of photo-multiplier tubes and associated electronics. Solid-state gamma-ray detectors are available, but are not yet commonplace. Currently, a company called Digirad ( http://www.digirad.com) ® is the primary producer of the Solid-state gamma camera. Gamma-cameras employ lead collimators to form an image of the radionuclide distribution in the body on the gamma-ray detector.
Gamma-camera performance is usually a balance of spatial resolution against sensativity. A typical gamma-camera will have a resolution of 4 to 6 mm and will be able to capture several hundred thousand gamma-ray 'events' per second. The gamma-camera will detect the X an Y position of each gamma-ray event, and these coordinates will be used to build an image, as shown above. In nuclear medicine, the value of an image pixel is the integral of gamma-ray events in that pixel position over time. In non-tomographic images, the pixel can also be thought of as the line integral of radionuclide distribution of a perpendicular line extending from the pixel position through the body of the patient. The units of a raw nuclear medicine image is 'counts' or 'kilocounts', refering to the number of gamma-ray events detected.
Since each nuclear medicine radionuclide has a unique gamma-ray emission energy spectrum, and since the energy of a gamma-ray is detected in a gamma-camera by the brightness of the scintilation associated with an event, gamma-cameras employ energy 'windows' to gate or limit the imaging process to gamma-ray events of particular energies. An energy window is usually tailored to the peak of the energy spectrum of a particular radionuclide, and to ignore other gamma-rays that would otherwise contribute noise to the image. This allows noise caused by compton scattering to be gated out.
This article is now very general, and does not actually mention any common scans (V/Q scintigraphy, bone scan, thyroid studies, SestaMIBI scans). I do not have access to a nice list. Does anyone else? JFW | T@lk 13:43, 2 Dec 2004 (UTC)
This article is hard to understand for those who don't have a background in radiology, maybe a few sections that are easier for the common audience to understand, for example those who are debating a career in radiology and would like to know their options

What entails nuclear medicine? Is radiation therapy part of it? Or it is mostly only nuclear imaging? fnielsen 08:13, 13 May 2005 (UTC)
Nuclear medicine encompasses diagnostic tests and therapeutic examinations. A large proportion of the diagnostic work involves imaging, and a smaller proportion (depending on the nuclear medicine department) involves non-imaging (e.g. the assay of blood samples to measure the glomerular filtration rate of the kidneys). Therapies with unsealed sources are also performed and are part of the field of nuclear medicine. -- AjAldous 14:42, 13 May 2005 (UTC)
The introduction should be updated so that the reader can clearly see that nuclear medicine refers to imagining, diagnostics, etc., NOT therapy for things like cancer treatment. Ajnosek ( talk) 23:34, 2 December 2011 (UTC)
A point was brought up in nuclear power - there's no discussion of the source of the specific radioisotopes mentioned in this article. Simesa 01:44, 19 August 2005 (UTC)
Page claimed that Chalk River produced two thirds of world supply of medical radioisotopes. Every other reference I've seen to Chalk River says it produces one third and Petten (Netherlands) produces another third - so when both were offline, two thirds of the world supply was offline. Corrected. 109.153.163.58 ( talk) 23:37, 31 August 2010 (UTC)
Hello I come from the french Wikipédia, I just warn you i upload a image. Enjoy!
1st line reference to exclusively "unsealed" sources is too specific since diagnostic imaging seems to be also included in this article - methods of which use sealed sources... ...and highlights the general confusion in this article which does not make a clear disctinction between imaging methods (i.e. where is PET?), diagnostic methods, and therapies; or between the various subdisciples of each.

Hey I'm new to this whole thing so I didn't want to change it myself but I believe new legislation in the US at least prevents most hospitals from doing their own radiopharmacy stuff (ie using a reactor to make tc 99m from molibdinum )but I'm just a nuc med student and don't necessarily trust myself as an authority, anybody know for sure? Here's the text I'm referring to:
Nuclear medicine diagnostic tests are usually provided by a dedicated department within a hospital --and may include facilities for the preparation of radiopharmaceuticals--. The specific name of a department can vary from hospital to hospital, with the most common names being the nuclear medicine department and the radioisotope department

Dear all,
This article needs updating and reorganization of information that would be more relevant to patients, clinicans, researchers, medical students or a general public with an interest in Nuclear Medicine. Since NM is a medical specialty, the article should focus more on the clinical aspect of NM, rather than the physics of NM or research topics. I am a member of the Society of Nuclear Medicine and will be editing the article over the next few weeks to bring relevant and updated information to Wikipedia. Thank you. Please let me know if you any suggestions. Thank you. Myohan ( talk) 21:26, 13 May 2009 (UTC)

Dear all,
I am a nuclear medicine physician in US. I have spent a lot of time over the last few weeks (as mentioned in above discussions) to make this article more relevant for the general public and provide useful information for patients, medical students, and technolgists. I am also working closely with the Society of Nuclear Medicine on this article to highlight and educate the general public about nuclear medicine. I appreciate the effort of previous authors and instead of deleting contents that were already available before, I have incorportated and reorganized the previous content into the current article. I didn't touch the section on "source of radioisotopes", "analysis", and "radiation dose". I also uploaded a few pictures of common NM scans. I hope people will find this article useful and informative. Thank you.

Radionuclide imaging or nuclear scintigraphy deserves a specific article, because nuclear medicine is a very broad field of study. It would facilitate all links to it - it's confusing when it's redirected to the whole field of study. Mikael Häggström ( talk) 19:10, 19 March 2010 (UTC)
