OBJECTIVE The aim of this study was to determine whether tube feeding affects the rate of gastric emptying determined by gastroesophageal reflux scintigraphy in pediatric patients. METHODS Gastroesophageal reflux scintigraphy studies of 700 pediatric patients aged 1 week to 16 years were retrospectively analyzed. From these, 350 subjects received their(More)
BACKGROUND AND PURPOSE Secondary hyperparathyroidism (SHPT) is a frequent and challenging issue in patients undergoing dialysis for chronic kidney disease. Surgical intervention in the form of parathyroidectomy is generally considered only in cases of severe SHPT. However, identification of the exact location of the parathyroid glands (PTGs) before(More)
OBJECTIVE Iodine-123 metaiodobenzylguanidine (I-123 MIBG) scintigraphy is gradually replacing I-131 MIBG scans in the diagnostic workup of neuroblastoma. High-dose I-131 MIBG, however, is commonly used for subsequent therapy in patients with proven MIBG-avid lesions. The objective of this study was to compare the sensitivities of pretherapy I-123 MIBG and(More)
A 16-year-old adolescent girl post total thyroidectomy for papillary thyroid carcinoma presented for postsurgical radioablative therapy. A whole-body I scintigraphy revealed not only expected activity in the thyroid bed but also asymmetric tracer distribution in the mandible and 2 foci of increased I accumulation in the distal left lower extremity. SPECT/CT(More)
BACKGROUND Spondylolysis is a defect of the pars interarticularis and is most commonly encountered in the lower lumbar spine of pediatric patients. Stress reaction of the pars interarticularis was regarded as an early stage of this pathological diagnosis in which no obvious anatomical change is detected. Both SPECT with (99m)Tc MDP and CT of the lumbar(More)
BACKGROUND Ventilation perfusion single photon emission computed tomography (V/Q SPECT) and CT pulmonary angiography have all been used in the diagnosis of acute PE. Previous studies have shown higher sensitivity and specificity and a marked decrease in the non-diagnostic rate of V/Q SPECT than planar scan. PURPOSE To systematically review and perform a(More)
BACKGROUND Gallium-68 somatostatin receptor positron emission tomography (PET) has been used in the diagnosis of neuroendocrine tumors (NETs). The compounds often used in molecular imaging of NETs with PET are 68Ga-DOTATOC, 68Ga-DOTATATE, and 68Ga-DOTANOC. There is varying affinity to different somatostatin receptors. PURPOSE To systematically review and(More)
PURPOSE The aim of this study was to systematically review and perform a meta-analysis of published data on the diagnostic value of F-fluorodeoxyglucose (F-FDG) PET/CT in the diagnosis of patients with fever of unknown origin (FUO). MATERIALS AND METHODS A comprehensive computer literature search of studies published through 31 March 2012 on the use of(More)
BACKGROUND Anti-1-amino-3-[18F]fluorocyclobutane-1-carboxylic acid (anti-3-18F-FACBC) positron emission tomography/computed tomography (PET/CT), 11 C-choline PET/CT, 111In-capromab pendetide, and T2-weighted magnetic resonance imaging (MRI) have been used for detecting prostate carcinoma relapse. PURPOSE To systematically review and perform a(More)
Constraint satisfaction problems (CSPs) in artificial intelligence have been an important focus of research and have been a useful model for various applications. Most CSP solving techniques rely on a single processor. With the increasing popularization of multiple processors, parallel search methods are becoming alternatives to speed up search processing.(More)
