SPECT leads for cardiac imaging of obese patients
Monday, November 28 | 3:40 p.m.-3:50 p.m. | SSE16-05 | Room S505ABIn this study from Brazil, researchers found that SPECT can overcome inherent limitations of other imaging modalities in myocardial perfusion imaging of obese patients. The findings are particularly important given that overweight people are at greater risk for adverse cardiac events.

Why utilization of SPECT MPI is on the decline
Monday, November 28 | 3:20 p.m.-3:30 p.m. | SSE16-03 | Room S505ABReductions in reimbursement and the subsequent closure of many private cardiology offices has led to a substantial contraction in the utilization of standard SPECT myocardial perfusion imaging (MPI) procedures, researchers from Philadelphia have found.

SPECT/CT can be valuable in abdominal emergencies
Monday, November 28 | 11:00 a.m.-11:10 a.m. | SSC10-04 | Room S505ABWhen faced with a gastrointestinal or genitourinary imaging emergency, adding SPECT/CT to the standard imaging options can help identify the source of the problem and lead to an appropriate intervention, according to this study.

PET tracers show when prostate cancer relapses
Sunday, November 27 | 11:55 a.m.-12:05 p.m. | SSA16-08 | Room S505ABThis presentation will discuss the efficacy of the PET tracers fluorocholine and carbon-11 acetate in patients with recurrent prostate cancer and low prostate-specific antigen levels.

PET offers important information for prostate cancer
Sunday, November 27 | 11:35 a.m.-11:45 a.m. | SSA16-06 | Room S505ABEven though PET imaging with fluorocholine or sodium fluoride provides different information on patients with prostate cancer, either PET option appears to be better than CT for assessing the extent of active metastatic skeletal disease.

Dynamic PET/CT and pathologic images for a 66-year-old male participant. (A) Axial dynamic PET/CT image acquired during intravenous administration of Ga-68 PSMA-11 demonstrates the hypermetabolic primary prostatic tumor. The right-sided portion of the lesion used for volume of interest (VOI) analysis is outlined in pink, reflecting the margins seen on a prior T2-weighted MRI scan. Tumor radiotracer uptake extends across midline into the left anterior apex (*). (B) Axial dynamic PET/CT image acquired during selective right prostatic arterial administration of Ga-68 PSMA-11 demonstrates intense radiotracer uptake in the VOI outlined in pink. There is comparatively minimal uptake in the unperfused left-sided portion of the tumor (*). The arterial sheath and catheters in the right groin are partially visualized (arrow). (C) Photomicrograph (hematoxylin-eosin stain; unmagnified) of the prostatic apex after radical prostatectomy. The midline (dotted line) and dominant tumor margins (solid line) are shown. Small additional areas of carcinoma (■) without T2-weighted MRI correlates were also identified at pathologic examination.
