Patients were studied in a PET/CT scanner (Biograph True Point PET/CT 64-Multislice Scanner; Siemens Medical, Erlangen Germany). Myocardial perfusion was assessed at rest and during adenosine stress. Rest imaging acquisitions started with a 740 MBq 13N-ammonia injection. After 30 min, pharmacologic stress was performed with an injection of adenosine during a 6 min period (140 g/kg/min). A second dose of 740 MBq of 13N-ammonia was injected at the third minute and imaging acquisitions started immediately with the injection, as described previously [8 (link)]. Two computed tomography-based transmission scans (120 kVp; 20–30 mA; pitch 1.5) were obtained prior to the rest perfusion studies and after the stress perfusion studies for positioning and correction of photon attenuation by soft tissue, respectively. Static, dynamic and gated datasets were obtained at rest and stress for further software analysis with automated QPET software (Cedars Sinai, Los Angeles, CA, USA). Ischemia was considered as a stress MBF < 1.85 mL/g/min in any vascular territory (left anterior descending artery (LAD), left circumflex artery (LCX) and right coronary artery (RCA)) [9 (link),10 (link),11 (link)]. In a different analysis, ischemia was considered as MFR <2.00 in each vascular territory [9 (link),10 (link),11 (link)].

Manufactured by Siemens
Sourced in Germany
The Biograph True Point PET/CT 64-Multislice Scanner is a medical imaging device that combines positron emission tomography (PET) and computed tomography (CT) technologies. It provides high-resolution, three-dimensional imaging of the human body by detecting the distribution of a radioactive tracer administered to the patient.

Scans were performed in a PET/CT scanner (Biograph True Point PET/CT 64-Multislice Scanner; Siemens Medical, Erlangen, Germany). Patients underwent an overnight fast and refrained from caffeine and theophylline 24 hours prior to the study. Dynamic data were acquired at rest and during adenosine stress, as previously described. 10 The 10-minute rest imaging acquisition started with a 740 MBq of 13 Nammonia i.v. injection. Pharmacological stress was performed after 30 minutes of the rest acquisition with an i.v. injection of adenosine during a 6-minute period (140 lgÁkgÁmin). A 10minute stress imaging acquisition started few seconds before the second dose of 740 MBq of 13 N-ammonia was injected i.v. at the third minute of the pharmacological stress. Static, dynamic, and gated datasets were obtained at rest and stress. 11 (link) Dynamic data were obtained during 6 minutes in 16 frames to calculate MBF (13 9 10, 2 9 30, and 1 9 60 seconds). A standard reconstruction (2D attenuation-weighted OSEM) was used with 3 iterations, 14 subsets, and 3D post-filtering with a 5-mm Gaussian kernel filter. Transverse data were reformatted to a 168 9 168 9 47 matrix with 2 mm pixels for each dynamic frame.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
