Inspiration-sleep-rest and nuclear medicine.

To the Editor: With great interest I have read the article under the title “Inspiration during the sleep stages without and after preceding exercise, as a factor supporting circulation of blood and the “resting procedure” by Grammaticos P, Daskalopoulou E, Grammaticou-Zilidou E, Kallistratos E, Daskalopoulos E. I think after testing this on a greater number of subjects it may be of major impact in sleep research in general. I would be especially interested if you wrote some words on the essential impact of this work in Nuclear Medicine in terms of routine protocols in brain and cardiac imaging.
