Issue Date: | 3-Feb-2014 | Publication information: | Frontiers in Oncology 2014; 4(): 11 | Abstract: | High resolution yttrium-90 ((90)Y) imaging of post-radioembolization microsphere biodistribution may be achieved by conventional positron emission tomography with integrated computed tomography (PET/CT) scanners that have time-of-flight capability. However, reconstructed (90)Y PET/CT images have high background noise, making non-target activity detection technically challenging. This educational article describes our image assessment technique for non-target activity detection by (90)Y PET/CT, which qualitatively overcomes the problem of background noise. We present selected case examples of non-target activity in untargeted liver, stomach, gallbladder, chest wall, and kidney, supported by angiography and (90)Y bremsstrahlung single-photon emission computed tomography with integrated computed tomography (SPECT/CT) or technetium-99m macroaggregated albumin SPECT/CT. | Gov't Doc #: | 24551594 | URI: | http://ahro.austin.org.au/austinjspui/handle/1/12086 | DOI: | 10.3389/fonc.2014.00011 | URL: | https://pubmed.ncbi.nlm.nih.gov/24551594 | Type: | Journal Article | Subjects: | SIR-spheres bremsstrahlung SPECT/CT diagnostic reporting technique non-target activity selective internal radiation therapy yttrium-90 PET/CT yttrium-90 radioembolization yttrium-90 resin microspheres |
