, Hoofdstuk 1: Medische Beeldvorming
= een onderzoek , waardoor een beeld (plaatje) van het inwendige lichaam gemaakt wordt.
= een belangrijk hulpmiddel bij stellen van diagnose & ook voor wetenschappelijk onderzoek.
1.1 Overzicht soorten van binnen uit
1.1.1.Van binnen uit:
1. Radionuclide (radiofarmacon) toedienen aan patiënt
2. Verdeling gemeten met extern detectiesysteem
1.1.1.1. Soorten apparatuur
Gamma-camera: verzameling van scintillatietelles met vaste detectoren.
- Teltechnieken NaI-kristal + elektronenvermenigvuldigers
Centrum van lichtdistributie bepalen
Plaats binnendringen -straal in kristal opp.
- Projectie van activiteitsverdeling in het lichaam op vlak van camera
d.m.v. multihole collimator tussen patiënt en kristal
NADELEN: Boven elkaar liggende organen worden op elkaar geprojecteerd
Attenuatie van straling in het lichaam: Bot absorbeert meer dan longweefsel
- Onderdelen:
o Detector
NaI-kristal (dikte = 0,5-2 cm; grootte =
50-60 cm)
Functie: gammastraling omzetten naar
lichtflits
o Collimator Pb (hoge Z-waarde)
groot aantal gaten 5000-4000 loodrecht
op detector
=> alleen gamma’s die loodrecht
staan op, vallen in op detector
o PMT buizen
X-Y positie bepaling
Z= pulshoogte van signaal
o Elektronische circuits
detector wordt ingedeeld in matrix
een kleurschaal wordt toegekend in functie van hoeveelheid straling die ingevallen is –
semikwantitatief werk
- Soorten opnames:
o Statisch
o Total body
o Dynamisch
SPECT = Single Photon Emission Computed Tomography
- Tomografische doorsneden geen superpositie
