Bladder herniation is an uncommon condition mimicking suspicious metastasis on PET/CT imaging. We report a 67 y/o man with prostate cancer referred for recurrence evaluation with 68Ga-PSMA-11 PET/CT. The scan showed an asymmetric site of intense tracer accumulation in the left inguino-scrotal region with the same SUVmax to the pelvic bladder. Reviewing cross sectional CT i...
In this research, sunflower oil that was extracted and refined at Shiraz Narges Oil Company was packed in four different containers, namely, clear PET (polyethylene terephtalate), yellow PET, yellow HDPE (high density polyethylene), and metal can. Samples were kept at ambient temperature in the shelf exposed to normal light for a period of 1 year. Peroxide values were determined at 45-day inter...
Combined PET/CT scanners now play a major role in medicine for in vivo imaging in oncology, cardiology, neurology, and psychiatry. As the performance of a scanner depends not only on the scintillating material but also on the scanner design, with regards to the advent of newer scanners, there is a need to optimize acquisition protocols as well as to compare scanner ...

در این تحقیق ژن np با استفاده از سایت www.encorbio.com/protocols/codon.htm به گونه ای طراحی شده است که حاوی نوکلئو تیدهای تغییر یافته مناسب میزبان ( e.coli) باشد. توالی ژن از طریق شرکت ندای فن سنتز گردید . ساب کلونینگ np در pet-22b: ابتدا ژن np و وکتور pet-22b با آنزیمهای noti و hindiii برش داده شده و ژن np از pge-vector خارج گردید.سپس وکتور و ژن فوق در واکنش ligation وارد گردیده و در e.coli ...
conclusion the fdg pet/ct showed a high sensitivity and a high negative predictive value for identifying malignancies in thyroid nodules with indeterminate fnab results. therefore, the fdg pet/ct may be a helpful tool in the clinical management of these nodules. when an fdg positive lesion is detected, further examination is recommended. background thyroid nodules with indeterminate fine-needle...
Interim 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (I-PET/CT) is a powerful tool for monitoring the response to therapy in diffuse large B-cell lymphoma (DLBCL). This retrospective study aimed to determine when and how to use I-PET/CT in DLBCL. A total of 197 patients treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) w...
background: positron emission tomography (pet) scan is a non-invasive, complicated and expensive medical imaging technology used for diagnosis and treatment of various diseases including cancers. this study aimed to evaluate the safety and effectiveness of this technology in iran. methods: the major medical electronic databases including cochrane library, google scholar, medline and iranmedex w...
Translational and Molecular Imaging Institute, Icahn School of Medicine at Mount Sinai, NY, NY, USA Current MR/PET systems employ segmentation of MR images and subsequent assignment of empirical attenuation map values for quantitative PET reconstruction. In this current study we examine the quantitative differences between our carotid artery imaging protocol on both a PET/CT and an MR/PET scann...
as a nuclear approach, positron emission tomography (pet) is a functional imaging technique which is based on the detection of gamma ray pairs emitted by a positron-emitting radionuclide. there are certain limitations to this technique such as normal tissue uptake. therefore, it has been recommended that patients prepare before scanning. fasting for a short while before pet imaging is an exampl...
