OBJECTIVE We examined the relationship between the response to treatment and prognosis of patients with aggressive lymphoma. METHODS We reviewed 33 patients with aggressive lymphoma treated with chemotherapy consisting of the CHOP regimen followed by radiotherapy. Twelve patients had Stage I, 13 had Stage II, 6 had Stage III and 2 had Stage IV disease. According to the International Prognosti...

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: 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 patients suspicious of...

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 In patients with Hodgkin's disease, the use of gallium-67 scintigraphy (Ga-67) compared to conventional staging and restaging techniques is still controversial. In particular, in a combined modality treatment with chemotherapy and radiotherapy given in sequence, its role in detecting active disease after chemotherapy may be useful in planning the subsequent radiotherapeutic strategy....

There are numerous imaging tests for diagnosing musculoskeletal infection. Radiographs are routinely performed, because even when not diagnostic, they provide an anatomic overview of the region of interest that could influence subsequent procedure selection and interpretation. Magnetic resonance imaging is sensitive and provides superb anatomic detail. Bone scintigraphy accurately diagnoses ost...
