OBJECTIVE: Conventional Single-photon emission tomography (SPET) myocardial perfusion imaging (MPI) is performed in the supine position range RAO 45o -LPO 45o , but the effect of other acquisition arcs on imaging quality have not been well described. In this study, we compared the radioactivity over left ventricle walls as measured by different acquisition arcs to identify the best specific applications. SUBJECTS AND METHODS: A total of 125 low-risk coronary heart disease patients underwent technetium-99m methoxy isobutyl isonitrile (99m Tc-MIBI) stress MPI, of which 52 received 360o acquisition with reconstruction using different 180o projections and the remaining 73 received conventional 180o (LPO 45o -RAO 45o ) and left-side 180o (POST 180o -ANT 0o ) acquisition consecutively...

Dear Editor, This rather original investigation was performed some time ago but is still unpublished. Its aim was to estimate the effect of low or high temperature cow's milk given to breast feeding rats in order to study possible influence of this diet to rats, to their physical growth and also esophageal mucosal pathology. Ten white female Wistar rats, 20 days of age were separated from their mothers and divided in 2 groups of 5 members each. Five of them were fed with milk kept at 42o C by using a special warming device...

Erdheim-Chester disease (ECD) is a rare non-Langerhans cell histiocytosis with lipid-laden macrophages and fibrosis. Although ECD is a multisystemic disease, the most common finding is sclerotic bone involvement in the diametaphyseal regions of bilateral distal femur and in proximal and distal tibia. We present a 40 years old woman who for the last two years had various systemic symptoms, especially knee pain, polyuria and polydipsia. Although a "hot knee" pattern was seen in bone scintigraphy (BS), a femur biopsy was performed, due to the preliminary diagnosis of haematologic malignancy...

The use of hyaluronic acid nanoshells has been proposed to encapsulate prodrugs and exploit the mechanisms of interactions between living cells, like endocytes or cancer cells and hyaluronic acid, which is a natural component of the extracellular matrix. In this review we describe the potential and the limits of this promising research trend and discuss the theoretical advantages of such an engineering approach. Is it a possible scalability to increase the efficacy and biodegradability of molecules like contrast media and radiotracers especially for neuroradiology and nuclear medicine studies...

A 3 years old boy was hospitalized with a month's history of polydipsia, polyuria and low fever. There was no relevant family history. This is a rare case of Langerhans cell histiocytosis (LCH) with both bone and pituitary infiltration shown on the technetium-99m methylene diphosphonate (99m Tc-MDP) scan and brain magnetic resonance imaging (MRI). Sagittal and coronal T1-weighted images on MRI showed the typical lack of high signal intensity of the posterior pituitary which corresponded to the central signs of diabetes insipidus (DI)...

BACKGROUND: Congenital erythropoietic porphyria (CEP) is a rare autosomal recessively inherited disorder with chronic and relatively stable presentation. Till now brain blood flow derangements have been described only in acute hepatic porphyrias. We describe the first findings of brain perfusion defects, studied by single photon emission tomography/computed tomography (SPET/CT), in two patients affected by CEP, by using a semi-quantification anatomic-standardized voxel-based program compared with magnetic resonance imaging (MRI) results...

Little was written in the stars above the city of Tabriz in Iran on March 15, 1938 indicating that a newborn citizen would immigrate to America and become a master of modern mo-lecular imaging with a sharp focus on 18 F-FDG PET to the benefit of millions of people around the world. Nonetheless, that's what happened. A gifted boy who lost his farther early and grew up with his uneducated mother and two siblings in humble circumstances to become a premium student, nationally no. 1 in mathematics while in school, and later a medical doctor before he decided in 1966 to seek his fortune in the US...

LETTER
Elias Mazokopakis
Dear Editor, I read with great interest the article by Son et al about the radioprotective effect of selenium (Se) supplementation for the salivary glands from 131 I treatment in patients with differentiated thyroid cancer (DTC). In this study, 8 patients received 300μg of Se (as inorganic sodium selenite; selenase®) orally for 10 days, 3 days before to 6 days after 131 I treatment. On the occasion of the use of Se among these patients, I want with this letter to remind the differences among the prescribed Se supplements in clinical practice, such as the possible health consequences of Brazil nut consumption as another choice for the preparation of DTC patients for radioactive iodine (RAI) therapy...

Ankylosing spondylitis (AS) is a form of arthritis that affects the spine, the sacroiliac joints and sometimes the hips and shoulders. Andersson lesion (AL), was first described by Andersson in 1937 as a destructive vertebral body and discovertebral portion of the spine in AS. In this case, we report a 50 years old man with medical history of AS diagnosed AL by fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (18 F-FDG PET/CT).

Inflammatory myofibroblastic tumor (IMT) is an uncommon neoplasm that has been described in various locations throughout the body, but is rarely observed in systemic lymph nodes. We present a case of a 63 years old woman with left inguinal lymphadenopathy accompanied by low-grade fever. Fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (18 F-FDG PET/CT) revealed abnormal higher 18 F-FDG uptake on the neck, axillar, pulmonary hilar, mediastinal, mesenteric, retroperitoneal, pelvic and inguinal lymph nodes...

Retroperitoneal pleomorphic liposarcoma (RPLS) is the least common but the most aggressive subtype of liposarcoma. We herein report a case of tumor embolism (TE) to the inferior vena cava (IVC) and pulmonary arteries in a 54 years old woman with RPLS. The case suggests that fusion fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (18 F-FDG PET/CT) can accurately detect occult TE. It also illustrates the usefulness of computed tomography (CT) and high 18 F-FDG uptake by PET/CT imaging for diagnosing such findings as filling defect in the veins and beaded pulmonary arteries as TE...
