MedicīnaVeselības aprūpeMedicineHealth CareDarba mērķis. Difūzijas uzsvērto attēlu sekvence (DWI) ir magnētiskās rezonanses metode, kam ir augsts potenciāls galvas smadzeņu bojājumu diagnostikā. Lai izvērtētu DWI sekvences īpašības, darba mērķis bija izvērtēt, vai intereses apgabala (ROI) lokalizācija, izmērs un slāņa lokalizācija ietekmē acīmredzamo difūzijas koeficientu (ADC). Materiāli un metodes. Tika izveidots 5% saharozes-agara smadzeņu parenhīmas imitācijas fantoms (diametrs - 21 cm, vidējais ADC - 1.87 x 10-3 mm2/s ), kas saturēja četrus cilindrus (diametrs - 2.7 cm) ar četrām vielām - 50% saharozes-agars, rapšu eļļa, 2.5% mannīts un ūdens. Šīs vielas reprezentē dažāda tipa audus. Datu mērījumi tika veikti ar 3T MRI aparatūru. ADC-...
