An Eminence SET-3000GCT/X (Shimadzu Corporation, Kyoto, Japan) PET scanner was used to measure radioactivity in the striatum. Dynamic PET scanning was performed for 30 to 60 minutes after i.v. bolus injection of 211.1 to 234.6 MBq/1.04 [0.44] (mean [SD]) μg [¹¹C]raclopride. The specific radioactivity of [¹¹C]raclopride was 33.5 to 163.3 GBq/μmol, and the injected mass of [¹¹C]raclopride was 0.47 to 2.35 μg. MRI of the brain was acquired with 1.5T MR imaging, Intera 1.5T Achieva Nova (Philips Medical Systems, Best, the Netherlands) as proton density image (echo time = 17 milliseconds; repetition time = 6000 milliseconds; field of view = 22 cm, 2-dimensional, 256 × 256; slice thickness = 2 mm; number of excitations = 2). These images were used for analysis of the PET scans.

A 1.5 T magnetic resonance (MR) scanner (Intera 1.5 T Achieva Nova, Philips Medical Systems, Best, Netherlands) was used to acquire a high-resolution 3D fast spoiled gradient echo T1WI sequence (180 slices, 1 mm thickness, TR = 9.3 ms, TE = 4.6 ms, flip angle 10°, field of view 25 × 25 cm). The images were used as a reference for drawing volumes of interest (VOIs) on SPECT or PET images.

We tested the method on a phantom and a human in a 1.5-T whole-body scanner (Intera Achieva 1.5-T Nova, Philips, The Netherlands) with a maximum gradient strength of 66 mT/m and a gradient slew rate of 160 mT/m/msec using a Philips 8-channel SENSE head coil.
We measured T₁ values using magnitude image. The maps of

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.
