Introduction: The malignant lymphomas are the fifth most common neoplasm in both men and women. Staging, re-staging and treatment response evaluation pose a difficult task in many patients of lymphomas. Histological variants in both Hodgkin’s and Non-Hodgkin’s types of lymphoma greatly affect the response to treatment and overall prognosis. Objective: This study was conducted to correlate the d...

Introduction: Despite widespread use of 67Gallium for lymphoma evaluation, timing of imaging after injection is a matter of controversy and to the extent of our knowledge no direct comparison has been made between early and delayed gallium images. We aimed to compare 24 and 48 hours post injection planar gallium imaging for evaluation of lymphoma recurrence. Methods: 255 pa...

The synthesis of gallium nitride nanowires (GaN NWs) by plasma enhanced chemical vapor deposition (PECVD) are successfully demonstrated in this work. The simple and green synthesis route is to introduce gallium oxide (Ga2O3) and nitrogen (N2) for the growth of nanowires. The prepared GaN nanowires have a single crystalline wurtzite structure, which the length of some nanowires is up to 20 μm, w...

Introduction Gallium-67 ( 67 Ga) has been used as a radionuclide for imaging a variety of solid tumors since 1969. Since then use of various gallium-based radiotracers has been reported. Recently, 67 Ga-labeled acetylacetate bis(thiosemicarbazones) ( 67 Ga-AATS) complex with significant tumor accumulation and fast blood clearance has been employed. Materials and Methods In this study, the absor...

Background: Diagnosis of active pulmonary and paranasal involvement in patients with Wegener’s granulomatosis (WG) can be difficult. The diagnostic value of gallium-67 scintigraphy in WG is unclear. Objective: To evaluate the added diagnostic value of gallium-67 scintigraphy in patients with WG with suspected granulomatous inflammation in the paranasal and chest regions. Methods: Retrospectivel...
