This[edit]

This comment may or not be debateable, however, use of the word "harmless" in relation to a contrast agent is misleading for these reasons:

 All radioisotope injections [contrast agents] carry some risk to certain patients. 

Therefore, if the contrast agent is described as "harmless" then it infers that there are no risks involved to any patients. 2] One risk is that the patient may be allergic to the contrast agent. There may be other risks but will not be mentioned here. The the object of this edit is to avoid reliance on the word "harmless." Gammarama 22:06, 24 May 2007 (UTC)

500µCi[edit]

This should be expressed primarily in SI units = 20MBq (actually its really 18.5 but we round it.)Squid57squid (talk) 14:34, 29 May 2009 (UTC)

Geiger Counter[edit]

The device used is usually called a intra-operative gamma probe, it does not contain a Geiger tube which would be much too insensitive and would not provide energy discrimination and so be less directionally sensitive. The detector in an intra-operative gamma probe is usually a cadmium-zinc-telluride radiation sensitive diode, i.e. a solid state device that converts ionization directly into an electrical signal. Less commonly they have a detector comprising a scintillant crystal such as caesium iodide optically coupled to a photmultiplier tube. Squid57squid (talk) 14:34, 29 May 2009 (UTC)

old science[edit]

The disadvantages section notes that lymph node removal may not even be effective. Indeed, as it is believed metastases rarely come from node growths (Weinberg 2013, The Biology of Cancer). Perhaps more of this research should be highlighted. — Preceding unsigned comment added by 96.232.103.102 (talk) 00:02, 5 December 2013 (UTC)
