简要总结
This clinical trial studies how well yttrium-90 (Y90) glass microspheres positron emission tomography (PET)/computed tomography (CT) works in imaging patients with liver tumors . Images produced by PET/CT may provide better information about the distribution of particles, such as Y90 glass microspheres, delivered for selective internal radiation therapy (SIRT) as compared to regular medical care images useing technetium Tc-99m albumin-aggregated single photon emission computed tomography (SPECT)/CT images.
详细描述
PRIMARY OBJECTIVES:
I. To evaluate the image quality of yttrium-90 (Y90) microspheres PET/CT post SIRT images as compared to technetium Tc-99m albumin aggregated (99mTc MAA) SPECT/CT.
SECONDARY OBJECTIVES:
I. To determine the superior accuracy in both distribution and dosimetry of Y90 PET/CT post-SIRT imaging compared to 99mTc MAA planar and SPECT/CT imaging.

结局指标
主要结局
Image Quality for 90-Y PET/CT Scans
时间窗: 1 day
Image quality for 90Y PET/CT scan images was assessed relative to the expected image quality of Standard of Care (SoC) 99mTc-MAA SPECT/CT scans obtained from the same participant. Assessments were conducted at 5, 10, 15 and 20 minutes after infusion. Scans were assessed on a 1 to 5 Likert scale by 2 Nuclear Medicine physicians who were blinded to patient information. The Likert scale for image quality was established as follows: 1. = Non-diagnostic 2. = Suboptimal 3. = Acceptable 4. = Good 5. = Excellent, equivalent to a SoC 99mTc-MAA SPECT/CT scan The scans for each individual participant at each timepoint was scored on the Likert scale, as determined by the 2 Nuclear Medicine physicians. The outcome is reported as the overall mean of the physician determinations for each time point, with standard deviation.
