Sentence examples for bold imaging from inspiring English sources

To accomplish this, simultaneous arterial spin labeling and BOLD imaging were used to measure the CBF and BOLD responses to flickering checkerboards with contrasts that oscillated continuously with frequencies of ~ 0.02 0.16 Hz.

An oncological radiologist inspected the images, and the slice location for BOLD imaging was chosen.

Thus, deoxygenated blood causes more signal loss on T2*-weighted images, a phenomenon exploited in blood oxygen level-dependent (BOLD) imaging (Howe et al, 2001) and brain activation studies (Hennig et al, 2003).

BOLD imaging uses the endogenous magnetic properties of deoxyhaemoglobin as a source of image contrast (Ogawa et al, 1990).

The scanner parameters were identical to those used in our previous study.48 T2* weighted images were obtained with a single-shot GE-EPI sequence used for BOLD imaging.

The combined use of BOLD imaging with animal models of drug addiction will be useful in determining the neuronal pathways associated with this mental disease.

Resting-state BOLD images were collected utilizing an echo planar imaging (EPI) sequence.

Although involvement of midbrain regions should be treated with caution in BOLD fMRI, MR-based perfusion imaging with gradient echo acquisitions has been shown to substantially decrease the risk of susceptibility artefacts and signal drop-outs compared to BOLD images because a minimum time of echo (TE) is used [26] [28], [16].

In this study, we first used simultaneously acquired ADC and BOLD functional imaging signals to identify brain voxels activated by ADC only, by both ADC and BOLD and by BOLD only, thereby delineating voxels relatively dominated by the arterial, capillary, and draining venous neurovascular compartments, respectively.

BOLD functional imaging utilized a gradient echo EPI sequence (32 slices 4.0 mm thick; slice gap 0.1 mm; field of view 230 × 230 mm; in-plane acquired resolution 2.9 × 2.9 mm; repetition time 3.0 s; echo time 35 ms; flip angle 90°; SENSE factor 2). Slices were oriented parallel with the inferior border of corpus callosum covering the whole brain.

Whole brain, dual-echo, BOLD GE-echoplanar imaging (EPI) images (repetition time (TR) = 2 s, echo time (TE1) = 13 ms, TE2 = 31 ms, voxel-size 3.5 × 3.5 × 3 mm, 36 slices) were collected during a breath-hold task (see below).
