Summary
The follow up of brain scans in 530 consecutive patients is presented. Positive results have been obtained using Hg 203-Neohydrin in 170 out of 203 (84%), intracranial tumours in 24 out of 61 (40%) cerebrovascular disorders and in 7 out of 23 (30%) head injuries.
The possibility of differentiating between tumours and infarcts is discussed: for this purpose, the morphology and the intensity of the positive focus, repetition of the scan at various intervals after the onset of the disease and after the injection of the tracer are valuable.
Zusammenfassung
Bericht über die szintigraphischen Untersuchungen bei einer Serie von 530 Fällen. Es wurde Hg-203-Neohydrin verwendet. Bei 203 intrakraniellen Tumoren ergaben sich 170 (84%) positive Befunde. Unter 61 zerebrovaskulären Schädigungen waren die Befunde 24mal (40%) positiv. 23 Fälle mit Schädelverletzungen ergaben 7mal (30%) Aktivitätsanreicherungen.
Die Möglichkeit einer Differentialdiagnose zwischen Hirntumoren und zerebralen Infarkten wird diskutiert. Von Bedeutung sind dabei die Gestalt und Intensität der Aktivitätsanreicherung, Wiederholung der Szintigraphie zu verschiedenen Zeitpunkten nach Einsetzen der Krankheitserscheinungen und zu verschiedenen Zeitpunkten nach Injektion der Aktivität.
Résumé
L'étude du «scanning» de 530 malades est présent`e. Des résultats positifs ont été obtenus en utilisant le Néohydrine-Hg 203 dans 170 sur 203 (84%) tumeurs intracrâniennes, dans 24 sur 61 (40%), désordres cérébrovasculaires, et dans 7 sur 23 (30%) traumatismes crâniens.
La possibilité de différencier les tumeurs et les infarctus est discutée: dans ce but, l'aspect et l'intensité du foyer, la répétition du scanning à intervalles variés après le début de l'affection et après l'injection du traceur, ont une réelle valeur.
Riassunto
Gli Autori discutono i risultati ottenuti con la fotoseintigrafia cerebrale con Neohydrin-Hg 203 in 530 pazienti. Scintigrafie positive sono state ottenute in 170 casi di tumori endocranici su 203 (84%), in 24 vasculopatie cerebrali su 61 (40%) ed in 7 traumi eranici su 23 (30%). Gli Autori discutono anche le possibilità di diagnosi differenziale scintigrafica tra tumori cerebrali ed infarti sulla base della morfologia e dell'intensità di captazione, e sui dati ottenuti da ripetute letture nel tempo dopo la somministrazione del tracciante e dopo l'instaurarsi della malattia.
Resumen
Se presenta un estudio del “scanning” de 530 enfermos. Se obtuvieron reaultados positivos con el empleo de Neohydrina Hg 203 en 170 tumores intracraneales de los 203 estudiados (84%). En 24 de 61 (40%) se observaron trastornos cerebro-vasculares y en 7 de 23 (30%) traumatismos craneales.
Se discute la posibilidad de diferenciar los tumores de los infartos, en este sentido el aspecto y la intensidad del foco, la repetición del scanning a intervalos diferentes después del comienzo de la affección y después de la inyeeción del vector tienen un valor apreciable.
