The radioisotope 67Ga (T 1/2 = 78 h) in extensively used as single photon marker for detecting the presence of malignancy and the diagnosis of inflammatory diseases. The high tumor specificity of carrier-free 67Ga make it one of the most interesting radionuclides in nuclear medicine for in vivo scanning studies. 67Ga is a cyclotron produced radioisotopes and is one of the radiopharmaceuti...
در سال های اخیر خواص ساختاری و الکتریکی نانو لوله های متنوعی در علوم مهندسی و کاربردی و تئوریکی مورد بررسی قرار گرفته است. هدف از مطالعه این پروژه بررسی اثر جذب گاز هیدروژن سیانید بر روی (4و4) آرمیچر و (0و8) زیگزاگ خالص و جایگزین شده با گالیوم ، نیتروژن و گالیوم- نیتروژن بر روی نانو لوله بور فسفید است. کلیه محاسبات با استفاده از تئوری dft و در سطح b3lyp/6-31g و نرم افزار گوسین 9 انجام شده است. ...
Background/Aim. Determining the value of Gissane?s angle (GA) plays a role in diagnosis and prognosis heel fractures, determining treatment methods, assessing outcome surgical treatment. Normal values GA vary relation to ethnicity, age, gender examined group, which indicates its anthropometric significance. The aim this study was determine range normal population Central Serbia.

UNLABELLED Cardiac PET using (18)F-FDG under fasting conditions (fasting (18)F-FDG PET) is a promising technique for identification of cardiac sarcoidosis and assessment of disease activity. The aim of this study was to investigate the usefulness of fasting (18)F-FDG PET in detecting inflammatory lesions of cardiac sarcoidosis from a pathophysiologic standpoint. METHODS Twenty-two patients wi...
Compton scatter, lead X-rays, and high-energy contamination are major factors affecting image quality in Ga-67 imaging. Scattered photons detected in one photopeak window include photons exiting the patient at energies within the photopeak, as well as higher energy photons which have interacted in the collimator and crystal and lost energy. Furthermore, lead X-rays can be detected in the main e...
