We used 11 clinical SPECT and 12 clinical CT images in this study. The SPECT scans were acquired on a Siemens Symbia T16 SPECT/CT system. The bone SPECT acquisitions were performed using our clinical bone SPECT protocol (120 views per bed position, and two energy windows with widths of 15% and centered at 140 KeV and 119 keV with the latter serving as a scatter window), followed by CT acquisition. The clinical CT images were acquired from 12 patients, with 8 on the Siemens SPECT/CT system and 4 on a GE CT system. Both SPECT and CT images were reconstructed using scanner software. The SPECT reconstructions were obtained using Flash 3D/OS-EM (with default numbers of iteration and subsets) with attenuation, energy-window-based scatter, and geometric collimator-detector response compensations enabled. Bone and lesion in the SPECT and CT images were manually delineated by consensus of two experienced radiologists, where the initial segmentation was produced by a radiology fellow and verified by an attending physician. Two different fellows produced the initial segmentations.
Spect ct system
Manufactured by GE Healthcare
The SPECT/CT system is a medical imaging device that combines Single Photon Emission Computed Tomography (SPECT) and Computed Tomography (CT) technologies. It is designed to capture both functional and anatomical information about the patient's body in a single examination.

Planar anterior and posterior gamma camera images were obtained on a GE SPECT/CT system 5–7 days after administration of 177Lu-J591 or 111In-J591. SPECT combined with low-dose CT of an area of interest was also performed but not used for the visual score assessment. For PSMA-PET imaging, the small molecular compound PSMA-11 (ABX Advanced Biochemical Compounds, Radeberg, Germany), also known as PSMA-HBED-CC, was utilized. PSMA-11 was conjugated to 68Ga. Study subjects received 5 mCi of 68Ga-PSMA-11 during the screening visit and prior to administration of radionuclide therapy. PET-CT, from vertex of skull to mid-thighs, was obtained 1–3 h after completion of infusion.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
