Personalized predictive lung dosimetry by technetium-99m macroaggregated albumin SPECT/CT for yttrium-90 radioembolization
BACKGROUND For yttrium-90 ((90)Y) radioembolization, the common practice of assuming a standard 1,000-g lung mass for predictive dosimetry is fundamentally incongruent with the modern philosophy of personalized medicine. We recently developed a technique of personalized predictive lung dosimetry using technetium-99m ((99m)Tc) macroaggregated albumin (MAA) single photon emission computed tomogra...
متن کاملDirect comparison of 99mTc-PSMA SPECT/CT and 68Ga-PSMA PET/CT in patients with prostate cancer
Objective(s): 99mTc-PSMA SPECT/CT is a cost effective alternative for 68Ga-PSMA PET/CT. The aim of this study was to directly compare these two techniques in patients with prostate cancer. Methods: 28 man with prostate cancer were studied using 99mTc-PSMA SPECT/CT and 68Ga-PSMA PET/CT in a shor...
متن کاملQUANTITATIVE PRETREATMENT 99mTc-MAA SPECT/CT AND FDG PET/CT VOI ANALYSIS OF LIVER METASTASES: RELATIONSHIP WITH TREATMENT RESPONSE TO SIRT
PURPOSE: In this study, using quantitive VOI analysis, the percentage Tc-MAA uptake and SUVmax and mean values of liver metastases obtained prior to SIRT by means of Theraspheres were related to treatment response. METHODS: Pretreatment FDG PET/CT scans and Tc-MAA SPECT/CT scans as well as post-treatment FDG PET/CT scans were coregistered and spherical VOI’s drawn around FDG positive liver lesi...
متن کاملComparison of SPECT/CT, SPECT, and planar imaging with single- and dual-phase (99m)Tc-sestamibi parathyroid scintigraphy.
UNLABELLED Various methodologies for (99m)Tc-sestamibi parathyroid scintigraphy are in clinical use. There are few direct comparisons between the different methods and even less evidence supporting the superiority of one over another. Some reports suggest that SPECT is superior to planar imaging. The addition of CT to SPECT may further improve parathyroid adenoma localization. The purpose of ou...
متن کاملQuantitative SPECT reconstruction using CT-derived corrections.
A method for achieving quantitative single-photon emission computed tomography (SPECT) based upon corrections derived from x-ray computed tomography (CT) data is presented. A CT-derived attenuation map is used to perform transmission-dependent scatter correction (TDSC) in conjunction with non-uniform attenuation correction. The original CT data are also utilized to correct for partial volume ef...
