• Patients with adenocarcinoma of the biliary tree (n = 26), with benign lesions of the bile ducts (n = 8), and 20 control patients underwent FDG-PET (370 MBq [18F]-FDG, Siemens ECAT EXACT HR(+)) [2].
• Dose-response relationships of serum lipid measurements with the extent of coronary stenosis. Strong, independent, and comprehensive. ECAT Angina Pectoris Study Group [3].
• Short-term prognostic value of lipid measurements in patients with angina pectoris. The ECAT Angina Pectoris Study Group: European Concerted Action on Thrombosis and Disabilities [4].

High impact information on ECAT1

• Two-thirds of the region pairs showed significant regressions, although percent differences were quite variable, with measures of glucose utilization ranging from 30 to 120% higher on the PC1024 compared to those from the ECAT II [5].
• METHODS: Twenty-one patients with coronary artery disease referred for (18)F-FDG PET underwent an imaging protocol of nongated 2D (2D-NG) and gated 2D (2D-G) acquisitions for 15 min each, followed by 3D gated acquisitions for 10 min (3D-10) and 5 min (3D-5), using an ECAT Exact HR+ scanner [6].
• Haemostasis factors in angina pectoris; relation to gender, age and acute-phase reaction. Results of the ECAT Angina Pectoris Study Group [7].
• Levels of ECAT from 0.30 to 0.90 mug/m(3) were significantly associated with infant wheezing [8].
• Twenty-seven patients (1 female, 26 males, age 62+/-9 years) with lung cancer or indeterminate pulmonary nodules were studied on the same day with a full-ring PET scanner (Siemens ECAT EXACT) and a coincidence gamma camera system (ADAC Vertex MCD) [9].

Chemical compound and disease context of ECAT1

• Global cortical CBF and CVR in 60 patients (66 +/- 12 yrs) with chronic hydrocephalus were investigated before, one week (7 d) and 7 months (7 m) after shunting by 15-O-H2O PET (Siemens ECAT 951/31) at rest and after application of acetazolamide (1 g) [10].
• METHODS: Fifty-eight patients with clinical suspicion of prostate cancer underwent (11)C-choline PET (25/58, Siemens ECAT Exact HR+) or PET/CT (33/58, Philips Gemini) scanning [11].

Biological context of ECAT1

• ECAT ART - a continuously rotating PET camera: performance characteristics, initial clinical studies, and installation considerations in a nuclear medicine department [12].
• Measurements were made using a positron emission tomography (ECAT II) and arterial blood sampling, during the sequential constant inhalation of C15O2 and 15O2 [13].
• In contrast, in spite of their lack of pluripotency, male germline stem (GS) cells expressed most ECATs and exhibited hypomethylation of ECAT promoter regions [14].
• Involvement of the hemostatic system in the insulin resistance syndrome. A study of 1500 patients with angina pectoris. The ECAT Angina Pectoris Study Group [15].

Anatomical context of ECAT1

• We observed a similar hypomethylation of ECAT loci in adult testis and isolated sperm [14].
• Emission transmission scans of the extra-cranial head, neck and thorax were obtained using an ECAT Exact 47 at least 60 min after injection [16].

Associations of ECAT1 with chemical compounds

• PET-TM was performed on an ECAT EXACT HR+ (CTI/Siemens) equipped with three rod sources of germanium-68 (380 MBq total) and extended septa [17].
• 18FDG (0.8 mCi/kg; 29.6 MBq) was given i.v. and PET (ECAT 953/31, Siemens) was performed for 90 min [18].
• Glucose metabolism was studied using an ECAT EXACT 47 positron emission tomography (PET) camera and fluorine-18 fluorodeoxyglucose (18F-FDG); 123I-IMT uptake was measured with the triple-headed single-photon emission tomography (SPET) camera, MULTISPECT 3 [19].
• The FDG images were acquired with two dedicated PET tomographs [Siemens ECAT 933, CTI (Knoxville, TN) and GE Advance, General Electric Medical Systems (Milwaukee, WI)] one hour after the intravenous administration of 10 mCi of FDG [20].
• Quantitative imaging of yttrium-86 PET with the ECAT EXACT HR+ in 2D mode [21].

Analytical, diagnostic and therapeutic context of ECAT1

• A study of injected dose for brain mapping on the ECAT HR+: activation maps for a parametric verbal working memory task [22].
• A dose of about 185 MBq (5 mCi) of these ligands was administered intravenously and a dynamic PET scan with an ECAT 931/08 PET camera was carried out [23].
• The PET/CT scanner was developed as a combination of a Siemens Somatom AR.SP spiral CT and a partial-ring, rotating ECAT ART PET scanner [24].
• PET studies in seven healthy human volunteers were performed on a Siemens ECAT EXACT whole-body scanner after injection of 100-280 MBq [L8F]FEF [25].
• Evaluation of the ECAT EXACT HR+ 3-D PET scanner in H2(15)O brain activation studies: dose fractionation strategies for rCBF and signal enhancing protocols [26].
