In this article the role of molecular imaging with SPECT and PET in patients with movement disorders is reviewed. It is mentioned that SPECT and PET imaging with cocaine analogues ((123)I-beta-CIT,(123)I-FP-CIT, (18)F-DOPA), radioligands labeling the presynaptic dopamine transporters, is of value for the differentiation of patients with PD or Parkinson-plus syndromes with individuals with essen...
Proteases play important roles during tumor angiogenesis, invasion, and metastasis. Various molecular imaging techniques have been employed for protease imaging: optical (both fluorescence and bioluminescence), magnetic resonance imaging (MRI), single-photon emission computed tomography (SPECT), and positron emission tomography (PET). In this review, we will summarize the current status of imag...
Brain imaging has progressed from exclusion of rare treatable mass lesions to a specific antemortem diagnosis. MR imaging-derived hippocampal atrophy and WMH are regarded as imaging biomarkers of AD and CVD respectively. Abnormal FP-CIT SPECT or cardiac iodobenzamide SPECT is a useful supportive imaging feature in the diagnosis of DLB. Frontal and/or anterior temporal atrophy and anterior defec...
The need to study dynamic biologic processes in intact small-animal models of disease has stimulated the development of high-resolution nuclear imaging methods. These methods are capable of clarifying molecular interactions important in the onset and progression of disease, assessing the biologic relevance of drug candidates and potential imaging agents, and monitoring therapeutic effectiveness...
Breast cancer radioimmunoscintigraphy targeting HER2/neu expression is a growing fieldof work in nuclear medicine research. In this study, trastuzumab was successively labeledwith [67Ga] GaCl3 after conjugation with DOTA-NHS-ester.The conjugates were purified by molecular filtration, the average number ofDOTA conjugated per mAb was calculated and total concentration was determined byspectrophot...

Integrated SPECT/CT scanners are gaining popularity as hybrid molecular imaging devices which can acquire SPECT and CT in a single exam. CT can be a low dose non-contrast enhanced scan for attenuation correction and anatomical localization, or a contrast enhanced diagnostic quality scan for additional anatomical characterization. We present a pictorial review highlighting the usefulness of this...
برش نگاری رایانه ای گسیل تک فوتون (spect) یک روش تصویربرداری بر اساس تزریق یک رادیوداروی گسیلنده گاما به بدن بیمار است. یک سامانه spect شامل دوربین (یا دوربین های) گاما است که با چرخش حول بدن بیمار و ثبت پرتوهای گامای ساطع شده از آن به جمع آوری اطلاعات در زوایای متفاوت (نگاره) می پردازد. این نگاره ها سپس به کمک الگوریتم های بازسازی، پردازش گشته تا در نهایت یک توزیع سه بعدی از توزیع پرتوزایی در ...
Today the majority of clinical molecular imaging procedures are carried out with single photon emitters and gamma cameras, in planar mode and Single Photon Emission Computed Tomography (SPECT) mode. Thanks to the development of advanced multi-pinhole collimation technologies, SPECT imaging of small experimental animals is rapidly gaining in popularity. Whereas resolutions in routine clinical SP...
