A new study shows that combining high resolution and high sensitivity collimation provides better quality images when using single photon emission computed tomography (SPECT) scans, said researchers at SNM's 56th Annual Meeting. Collimators - devices that filter a stream of rays so that only those travelling parallel to a specified direction are allowed through - are used in SPECT because it is not yet possible to focus radiation with such short wavelengths into an image with the use of lenses. Using the two types of collimation in tandem is especially effective for better imaging of small tumours, the study indicates...
