Udayasankar MD, FRCR : Nothing to Disclose Guiyun Wu MD : Nothing to Disclose Stephen Edward Jones MD, PhD : Nothing to Disclose TEACHING POINTS 1. Emphasize the clinical significance of simultaneous PET/MRI in the improving the detection of epilepsy foci. 2. Illustrate with simultaneous fused-FDG-PET/MRI findings of epileptic foci. TABLE OF CONTENTS/OUTLINE 1. Briefly review the role of MRI in epilepsy a. Discuss current MRI imaging findings and limitations in the evaluation of epilepsy foci. Limited to focal cortical dysplasia, meso temporal sclerosis, polymicrogyria and heterotopia. 2. Describe current technical advances in PET/MRI and its use in neuroimaging. 3. Discuss the clinical utility of fused-FDG-PET/MRI for evaluation of epilepsy foci and advantages over structural MRI. Fused-PET/MRI is a modality that offers superior diagnostic advantages. Patients with medically refractory epilepsy may be candidates for surgery. This cohort of patients may have a positive surgical outcome with the identification of epileptic foci on MRI. However, some patients show indeterminate or no evidence of structural abnormality on MRI. In these subset of patients, fused-FDG-PET/MRI is increasing being used as a tool to enhance pre-surgical identification of epileptic foci. Learn the clinical utility of fused-FDG-PET/MRI and its advantages - such as new regions of hypometabolic epileptic foci not seen on MRI and ability to delineate anatomic boundaries of hypometabolism not identified on PET.

Werner : Nothing to Disclose Abass Alavi MD : Nothing to Disclose TEACHING POINTS To review different molecular imaging techniques for diagnosis and assessment of venous thromboembolism (VTE). To review applications of clinical routine molecular imaging techniques for diagnosis of VTE and tumor thrombosis. TABLE OF CONTENTS/OUTLINE Venous thromboembolism (VTE) is a blood clotting disorder mostly presenting as deep vein thrombosis (DVT) and pulmonary embolism (PE) which affects up to 600,000 individuals in United States each year. Clinical symptoms of VTE are nonspecific and sometimes misleading. Additionally, side effects of available treatment plans for VTE are significant. Therefore, medical imaging plays a crucial role in proper diagnosis and avoidance from over/under diagnosis, which exposes the patient to risk. Molecular imaging techniques with different tracers have been studied for diagnosis of VTE and have shown promise in aiding the conventional structural imaging of VTE. In this exhibit we will briefly review following topics: 1. Molecular imaging methods for diagnosis of VTE i. SPECT / scintigraphy a. Ventilation-perfusion scan b. Anti D-Dimer c. GP IIb/IIIa Cyclic RGD Peptide d. Antifibrin antibodies ii. PET/CT a. FDG b. EP-2104R iii.

TABLE OF CONTENTS/OUTLINE 18F-FDG PET/CT is a noninvasive, accurate and reproducible imaging modality that can identify and quantify inflammatory processes and prognosticate the risk for acute cardiovascular disease. Imaging vascular calcification by sodium 18F fluoride PET/CT can possibly improve cardiovascular risk stratification by detecting calcification in vascular wall and also differentiate active from indolent calcification. In this review, we will discuss advances and improvements in application of FDG-PET/CT and sodium 18F Fluoride PET/CT in atherosclerotic plaque inflammation and effects of methodological factors on accurate quantification of vessel wall inflammation. 1) FDG-PET/CT 2) Sodium 18F Fluoride 3) Methodological factors i.

  • Renal Phosphate Wasting Due to Tumor-Induced (Oncogenic) Osteomalacia
    Open Access Case Report DOI: 10.7759/cureus.15507 Renal Phosphate Wasting Due to Tumor-Induced (Oncogenic) Osteomalacia Eluwana A. Amaratunga 1 , Emily B. Ernst 1 , James Kamau 1 , Ragarupa Kotala 1 , Richard Snyder 1 1. Internal Medicine, St. Luke’s University Health Network, Easton, USA Corresponding author: Eluwana A. Amaratunga, [email protected] Abstract Osteomalacia is a widely prevalent bone disorder that is caused by an imbalance in body calcium and phosphate. Tumor-induced osteomalacia (TIO) is a rare form of osteomalacia that is associated with mesenchymal tumors. It is caused by overproduction of fibroblast growth factor 23 (FGF-23), a hormone involved in phosphate regulation. A 59-year-old male with a history of factor V Leiden mutation, pulmonary embolism, and deep vein thrombosis was diagnosed with oncogenic osteomalacia in 2008 following laboratory findings significant for low phosphorus and elevated FGF-23 levels. He underwent a resection of a right suprascapular notch mass with the biopsy confirming a phosphaturic mesenchymal tumor. He was maintained on oral phosphorus and calcitriol replacements with a regular follow-up with oncology and nephrology. Eight years later, the patient’s phosphorus levels started declining despite replacement. A repeat test showed FGF-23 levels once again elevated. A whole-body magnetic resonance imaging (MRI) scan showed no significant findings. The patient was continued on oral replacement therapy with a close follow-up. Two years later, urine phosphorus excretion was elevated at 2494 mg per 24 hours with low plasma phosphorus (1.2 mg/dL) and an elevated FGF-23 level of 1005 relative units (RU)/mL.

Abstract Oncogenic osteomalacia is a rare paraneoplastic syndrome resulting from an increased secretion of a fibroblast growth factor 23 (FGF23), generally by a benign mesenchymal tumor. We report a case of a 60 years old female patient who had chronic bone pain.

Investigations revealed hypophosphataemia, phosphaturia, undetectable serum 1,25- dihydroxyvitamin D and severe osteomalacia on bone biopsy, suggestive of a diagnosis of oncogenic osteomalacia. Thorough physical examination did not locate a tumour. Support for the diagnosis was obtained by detection of phosphate uptake inhibitory activity in a blinded sample of the patient's serum using a renal cell bioassay. On the basis of detection of this bioactivity, a total body magnetic resonance (MR) examination was performed. A small tumour was located in the right leg. Removal of the tumour resulted in the rapid reversal of symptoms and the abnormal biochemistry typical of oncogenic osteomalacia.

Doshi, MDb, Michael C. Roarke, MDa, Ba D. Nguyen, MDa a Department of Radiology, Mayo Clinic, AZ b Division of Endocrinology, Department of Internal Medicine, Mayo Clinic, AZ Tumor induced osteomalacia (TIO) is a rare paraneoplastic syndrome caused by overproduction of fibroblast growth factor 23 (FGF23) secreted by benign mes- enchymal neoplasm. Due to its nonspecific clinical presentation or lack of awareness, the diagnosis of TIO is often significantly delayed resulting in patients' prolonged physical suffering or psychological distress. Successful detection or complete surgical resection of the causative tumor typically leads to rapid resolution of symptoms or reversal of biochemical imbalance. Nuclear medicine and molecular imaging have been playing a promising role as the first- line imaging modalities in the diagnosis and localization of occult FGF23 secreting mesenchymal tumor, especially with the emerging whole-body, head-to-toe Ga68-DOTATATE PET/CT technique. Combined focused diagnostic CT and/or MRI are imperative for accurate delineation of tumor and surgical guidance. © 2018 Elsevier Inc. All rights reserved.
