gives some idea

Thank you Mushtaq Ahmad

Thank you so Olena Polyakova

yes my question is about the sampling size how many patients that I have to take for each scan ( renal - bone - lung - thyroid - parathyroid - cardinal

Whole body )

my research will be for adult patients only

and I will do the study for stander size ( 70 - + 10 kg)

so the more patients that I take , the better results I will have

Is their any body did similar study in his / her country can share me his / her experience or the research paper ?

yes my study will include renal scan also

Shall I category the age as follow

20-40 years 50-80 patients

40-60 years 50-80 patients

or

20-30 years 50-80 patients

30-40 years 50-80 patients

50-60 years 50-80 patients

What do you think is better ?

Thank you so my much Olena Polyakova

I read the article but the author did not mentioned the sampling size for the patients , he mentioned sampling size for hospitals and I sent him a message to ask about the sampling size for the patients bout he has not answered until now
