Study Design: Retrospective study.Purpose: This study aims to semiquantitatively evaluate the standardized uptake value (SUV) of <sup>99m</sup>Tc-methylene diphosphonate (MDP) radionuclide tracer in the normal vertebrae of breast cancer patients using an integrated single-photon emission computed tomography (SPECT)/computed tomography (CT) scanner.Overview of Literature: Molecular imaging techniques using gamma cameras and stand-alone SPECT have traditionally been utilized to evaluate metastatic bone diseases. However, these methods lack quantitative analysis capabilities, impeding accurate uptake characterization.Methods: A total of 30 randomly selected female breast cancer patients were enrolled in this study. The SUVmean and SUVmax values for 286 normal vertebrae at the thoracic and lumbar levels were calculated based on the patients’ body weight (BW), body surface area (BSA), and lean body mass (LBM). Additionally, 106 degenerative joint disease (DJD) lesions of the spine were also characterized, and both their BW SUVmean and SUVmax values were obtained. A receiver operating characteristic (ROC) curve analysis was then performed to determine the cutoff value of SUV for differentiating DJD from normal vertebrae.Results: The mean±standard deviations for the SUVmean and SUVmax in the normal vertebrae displayed a relatively wide variability: BW=3.92±0.27 and 6.51±0.72, BSA=1.05±0.07 and 1.75±0.17, and LBM=2.70±0.19 and 4.50±0.44, respectively. Generally, the SUVmean had a lower coefficient of variation than the SUVmax. For DJD, the mean±standard deviation for the BW SUVmean and SUVmax was 5.26±3.24 and 7.50±4.34, respectively. Based on the ROC curve, no optimal cutoff value was found to differentiate DJD from normal vertebrae.Conclusions: In this study, the SUV of <sup>99m</sup>Tc-MDP was successfully determined using SPECT/CT. This research provides an approach that could potentially aid in the clinical quantification of radionuclide uptake in normal vertebrae for the management of breast cancer patients.

Myocardial perfusion imaging (MPI) with single photon emission computed tomography (SPECT) is generally used to evaluate myocardial ischemia in patients with known or suspected coronary artery disease. Cardiac CT, on the other hand, enables non-invasive visualization of the coronary vessels. Myocardial bridging (MB) is a congenital anomaly characterized by an intramyocardial route of a coronary artery. It is commonly considered benign and rarely requires further evaluation or intervention. However, its clinical complications can be hazardous. We report a patient whose SPECT MPI study demonstrated a mild reversible perfusion defect at the apical anterior segment of the left ventricle that was later attributed to MB visualized on cardiac CT.
