If the differential diagnosis between these diseases was the case, other examinations are much more accurate, such as PET (Positron Emission Tomography) with 18F-Fluorodeoxyglucose (FDG) and cardiac scintigraphy with123I- MIBG. Moreover, in the case the clinical picture fully matches the criteria for the diagnosis of Parkinson\u2019s disease and the patient responds to dopaminergic treatment in the proper way, diagnostic confirmation with SPECT and DAT radiopharmaceutical is not needed. This examination should be limited to the cases in whom the clinical picture and\/or the poor response to dopaminergic treatment raise the question whether the patient is really affected by Parkinson\u2019s disease (or another degenerative Parkinsonism) or instead by a non-degenerative Parkinsonism (i.e., .: jatrogenic, psycogenic, or vascular). The inappropriate use of brain SPECT with DAT radiopharmaceuticals has contributed to cause long waiting lists that are ususally of several months, thus enlonging the diagnostic procedure for those patients who instead really need the result of this examination in order to receive a correct diagnostic judgment and subsequent proper treatment.<\/p>\n","protected":false},"featured_media":2435,"template":"","meta":{"_edit_lock":["1570005929:5"],"_edit_last":["5"],"_thumbnail_id":["2435"],"_wpml_word_count":["{\"total\":402,\"to_translate\":{\"it\":402}}"],"_yoast_wpseo_primary_eta":[""],"_yoast_wpseo_primary_disciplina":["103"],"_yoast_wpseo_primary_tipologia":[""],"wpcf-pacchetto":["AIMN #1"],"wpcf-bibliografia":["1.
