Ym mis Medi 2021, cyhoeddodd Coleg Brenhinol y Seiciatryddionastudiaeth achos o ddenhddio sganio FDG-PET i gynorthwyo â diagnosis dementia. Roedd yr astudiaeth achos hon yn manylu ar brosiect peilot a sefydlwyd ddiwedd 2019 gan Fwrdd Iechyd Prifysgol Aneurin Bevan, gyda chefnogaeth y Coleg Brenhinol a Chanolfan Ymchwil a Diagnosteg Delweddu PET Cymru. Nod y prosiect oedd bod o fudd i gleifion yn ardal Gwent, gan gynyddu diagnosis cynharach a chyfraddau diagnosis ar gyfer dementia, sicrhau diagnosis mwy dibynadwy o is-deip dementia, gan alluogi triniaeth gynharach sy'n benodol i glefydau, a mynediad at gymorth seicogymdeithasol a lleihau baich gofalwyr. Mae'r gwaith hwn bellach yn cael ei wneud ar raddfa fwy ac mae Pwyllgor Gwasanaethau Iechyd Arbenigol Cymru yn comisiynu sganiau FDG-PET ar gyfer dementia yn genedlaethol.
In September 2021, the Royal College of Psychiatrists issued acase study of the utility of FDG-PET scanning to aid dementia diagnosis. This case study detailed a pilot project that was established by Aneurin Bevan University Health Board, supported by the Royal College and the Wales Research and Diagnostic PET Imaging Centre, in late 2019. The project aimed to benefit patients in the Gwent area, increasing earlier diagnosis and diagnostic rates for dementia, achieving more reliable diagnosis of dementia subtype, enabling earlier disease-specific treatment and access to psychosocial support and reduction of carer burden. This work is now bring scaled up, with the Welsh Health Specialised Services Committee commissioning FDG-PET scans for dementia nationally.
