Si potranno prevedere anche lesioni che si svilupperanno in futuro
Una telecamera termica per la dignosi in dermatologia

Una camera ad alta tecnologia simile a quelle che compiono rilevazioni termiche per individuare anomalie su un paesaggio, come foreste infettate da un organismo patogeno, potrebbe essere usata per aiutare a identificare problemi dermatologici. “I medici spesso diagnosticano la psoriasi attraverso valutazioni visive che sono molto soggettive, ma si può agire per usare imaging tecnologico che potrebbe ssere molto più accurato”, ha dichiarato Francisco Tausk, della University of Rochester, autore dello studio.
In alcuni trial preliminari, delle camere termiche sono state usate per quantificare l’arrossamento dovuto all’incremento di circolazione sanguigna sotto le lesioni alla pelle, che la rende più calda. Poi attraverso fotografie alla luce ultravioletta, gli scienziati sono stati in grado di individuare placche piu’ dure, che i ricercatori dicono contenere un aminoacido responsabile della fluorescenza. L’approccio che si basa su queste due fasi aiuterà a guardare la pelle molto meglio di quanto si faccia a occhio nudo, in modo da poter prevedere lesioni che si svilupperanno in futuro.
