The study was approved by the institutional review board and written informed consent was obtained prior to subject participation in the study. The sequence was evaluated on 9 healthy volunteers (age: 25–41 years, 4 females) for brain perfusion imaging and in 5 healthy volunteers (age: 23–39 years, 2 females) for kidney perfusion imaging. All imaging was performed on a 3T Ingenia MR scanner (Philips Healthcare, Best, The Netherlands). Subjects were placed in the supine, head-first position with a 32-channel head coil for brain imaging, while they were positioned supine, feet-first with a 16-channel anterior torso coil and respiratory bellows for kidney imaging.

Neurofeedback for Emotion Regulation

Check if the same lab product or an alternative is used in the 5 most similar protocols
Neurofeedback was performed at the International Tomography Center at Novosibirsk using a 3 T Philips Ingenia MR scanner. Each session consisted of two parts (the first one 15 min and the second one 10 min). In each odd sessions, both parts were using the neurofeedback condition, while in each even sessions, the second part was a transfer session without feedback signal.
Both, the neurofeedback and the transfer sessions comprised alternating blocks of up- and down-regulation of the hemodynamic activity in the target area, with a duration of 40 and 20 s, respectively. Participants were not provided with predetermined strategies, yet they were told that optimal strategies for upregulation would be related to positive emotions. In order to downregulate the target RoI emotionally, neutral strategies were recommended.

Brain Imaging: T1-weighted MRI and SPECT

Check if the same lab product or an alternative is used in the 5 most similar protocols
For anatomical reference, a T1-weighted (T1w) MRI scan of the brain was obtained on a 3.0-T Ingenia MR scanner (Philips Healthcare, Best, The Netherlands) using a 32-channel receive-only head coil and the following scan parameters: TR/TE 7/3.18 ms; flip angle 9°; 1 mm isotropic resolution. Individual SPECT scans were co-registered to individual MRI scans using 6-parameter rigid body registration in SPM12 (Wellcome Centre for Neuroimaging, London, UK) (Fig. 2). To optimize registration, a high-intensity striatal mask was superimposed on the T1w scan to resemble the contrast on the SPECT scan.

High-resolution structural imaging and magnetic resonance spectroscopy were acquired using a 3.0 Tesla Philips Ingenia MR scanner (Philips Medical System, Bests, Netherlands). For spectroscopic voxel localization and tissue segmentation, high resolution T1-weighted images were acquired using a three-dimensional T1-weighted magnetization-prepared rapid gradient echo sequence with the following parameters: repetition time (TR) = 7.4 ms, echo time (TE) = 3.4 ms, flip angle (FA) = 8°, field of view (FOV) = 220 × 220 mm2, slice thickness = 1 mm, number of excitation (NEX) = 1,180 contiguous sagittal slices. GABA+ and Glx levels in the VOI were measured using the Mescher-Garwood point-resolved spectroscopy (MEGA-PRESS) sequence with the following parameters: TR = 2,000 ms, TE = 68 ms; number of signal averages = 320, scan duration = 11 min, water suppression method = multiple optimizations insensitive suppression train, second-order pencil beam shimming. During odd-numbered acquisitions, Gaussian inversion pulse was applied at 1.9 ppm3 CH2 resonance of GABA, influencing the J-coupled peak at 3.02 ppm (EDIT-ON). The same pulse was provided symmetrically to the other side of the water peak at 7.5 ppm for even-numbered acquisitions (EDIT-OFF).

Pelvic MRI Segmentation Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
Pelvic MRI was performed by a Philips INGENIA™ MR scanner with a field strength of 3.0 T and the patient in the supine position. The scanning parameters included: Repetition time = 3565 ms; echo time = 80 ms; layer thickness = 5 mm; image matrix = 312 ´ 357, field of view = 250 ´ 340 ´ 166 mm.
The sequence of fast spin-echo (FSE) T2-weighted MRI with a large field of view with fat suppression obtained in the axial plane of the entire pelvis was retrieved from the Picture Archiving and Communication System for image segmentation. A total of 9476 T2-weighted MR images were collected from the enrolled patients. Fifteen patients in the training set were randomly selected by random number tables and 367 images from these patients served for manual labeling. A radiological expert with > 15 years of experience in pelvic MRI labeled three target regions (pelvis, mesorectum, and tumor body) on each of the consecutive T2-weighted images. These regions were represented by drab, yellow, and green, respectively (Supplementary Figure 1), using an open annotation tool named Labelme (available at labelme.csail.mit.edu)[31 ]. Data were transformed into the Common Objects in Context (COCO) dataset format[32 ].

MR imaging was performed using a 1.5T Ingenia MR scanner (Philips Healthcare, Best, The Netherlands). The integrated RF body coil was used for transmission and a torso‐sized RF array coil was used for reception. Transverse T1‐weighted images were acquired using a 3D spoiled gradient‐echo sequence (TR/TE = 7.6/4.6 ms, flip angle = 10◦, voxel size = 1.33 × 1.33 × 2 mm3, field of view = 320 × 320 × 240 mm3, receiver bandwidth = 271 Hz/pixel) with an acquisition time of 3 min and 39 s. Images were reconstructed using vendor‐supplied routines for image‐based intensity normalization and three‐dimensional gradient nonlinearity correction.

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.
