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...
A 46-year-old woman with multiple myeloma presented with neurological symptoms in the right upper extremity. After MR imaging of the cervical spine failed to show the cause of her symptoms, Ga-67 scintigraphy demonstrated increased uptake in multiple areas including the right supraclavicular region and bilateral lower extremities. Histology of the specimen obtained from the left thigh proved so...
نانوذرات ابر پارامغناطیسی اکسید آهن (SPION) پس از تهیه شدن، با هدف بررسی پراکنش زیستی این ذرات در بدن موش صحرایی، با گالیم-67 نشاندار شدند تا Ga]-SPION67[ به دست آید. نانوذرات ابر پارامغناطیسی اکسید آهن با دانهبندی کوچک با روش همرسوبی با استفاده از نمکهای آهن 3Fe+ و 2Fe+ با نسبت مولی 2 به 1 سنتز شدند. از روشهای شناسایی XRD، TGA، DSC، V...
tc-99m mibi has recently been used in the functional imaging of various tumors. this prospective study was performed to evaluate the role of tc-99m mibi imaging at the time of the initial staging, assessment of treatment response, follow-up studies and survaillance in hodgkin’s and non-hodgkin’s iymphoma. 25 patients (14 with hodgkin’s and 11 with non-hodgkin’s iymphoma) underwent 32 studies. t...
In order to develop a possible C-X-C chemokine receptor type 4 (CXCR4) imaging agent for oncological scintigraphy, [(67)Ga]-labeled 1,1'-[1,4-Phenylene-bis(methylene)]bis(1,4,8,11-tetraazacyclotetradecane) ([(67)Ga]-AMD3100) was prepared by using [(67)Ga]GaCl3 and AMD-3100 for 2 h at 50 °C (radiochemical purity: >95% ITLC, >99% HPLC, specific activity: 1800-2000 TBq/mmol) in acetate buffer. The...
he introduction of computed tomography (CT) has greatly improved lymphoma staging procedures and is presently the most common and most important radiologic technique employed for this purpose and for evaluating the response to treatment. However, since CT only gives an anatomic measure of the tumor, in some cases (particularly those with bulky mediastinal involvement), it is not useful in disti...
