2518 Objectives Iterative PET image reconstruction modeling the camera response offers the advantage of improving the spatial resolution while maintaining image noise. As such algorithms are becoming more widely used, in this study we evaluate the clinical applicability of such algorithms for lesion detectability and SUV measurements Methods PET/CT studies in 10 oncologic subjects consisting of 6 females and 4 males with an average age of 57.2 years (18F-FDG in 9 and 64Cu-ATSM in 1) previously p...

Despite early detection programs, many patients with prostate cancer present with intermediate- or high-risk disease. We prospectively investigated whether 11 C-acetate PET/CT predicts lymph node (LN) metastasis and treatment failure in men for whom radical prostatectomy is planned. Methods: 107 men with intermediate- or high-risk localized prostate cancer and negative conventional imaging findings underwent PET/CT with 11 C-acetate. Five underwent LN staging only, and 102 underwent LN staging a...

1001 Learning Objectives FDG-PET-CT is routinely performed as part of the imaging work up for many primary malignancies. Incidental finding of cardiovascular involvement can change both disease staging as well as intended patient management and thus significantly influence the final outcome. Purpose: Many of the cardiovascular masses remain undiagnosed due to a lack of clinical suspicion. By virtue of their location, these can cause a range of cardiovascular complications, which could be life th...

Patients with rising prostate-specific antigen (PSA) levels after definitive local therapy of prostate carcinoma present a diagnostic dilemma. A local recurrence would be amenable to additional local therapy with curative intent, whereas metastatic disease would require palliative androgen ablation therapy. In this study, we evaluated the effectiveness of PET with 11 C-acetate (AC PET) for evaluation of patients with rising PSA after radical prostatectomy or radiation therapy. We also compared t...

Transmyocardial laser revascularization (TMR) reduces anginal class and is indicated for severely symptomatic patients who are not candidates for conventional revascularization. This report describes a 72-year-old man who presented 4 years following initially successful TMR with recurrent angina refractory to maximal medical management. Reoperative TMR was performed with substantial improvement in angina and functional class.

OBJECTIVE: To assess the utility of intravenous dipyridamole thallium testing for predicting major cardiac events following acute myocardial infarction in older patients. DESIGN: Prospective cohort study with a median follow-up of 18 months. SETTING: A university teaching hospital. PARTICIPANTS: 73 patients aged 65 years and older with enzymatically confirmed acute myocardial infarction (mean age 75 years, 56% male, 71% white). MEASUREMENTS: All patients underwent a detailed clinical assessment,...
