Reduced whole brain volume81,82, with greater reductions more frequently observed in the frontal lobes have also been reported in relation to impaired insight52,83. Of note, a few other studies have reported no association between reduced brain volume and impaired insight84,85,86,87. The ...
Ipsilateral low CBF-ASL values were observed in frontal lobes and thalami with a putaminal hemorrhage and lentiform nuclei, temporal lobes, and parietal lobes with a thalamic hemorrhage, suggesting that ASL-MRI showed the ipsilateral cerebral diaschisis (ICD). In the putaminal hemorrhage patients, ...
4c, cyan arrow) specifically affected the 9th TI, where the liver tissue was expected to appear dark. Collectively, these motion artifacts contributed to inaccuracies in perfusion quantification across the lobes. For the MV group, no obvious deviating ASL signal (Fig. 5d, e) was observed. The...
Among major brain lobes, frontal CBF had the highest sensitivity in predicting future cognition, with a significant effect observed for fluid cognition (β=0.244 P =0.001), episodic memory (β=0.294, P =0.001), and reasoning (β=0.186, P =0.027). These associations remained significant after ...
Relationship between the CBF values and cognition was investigated using correlation analysis. A receiver operating characteristic (ROC) curve was generated for CBF measurements in posterior cingulate region. AD patients with PLD of 1.5s showed lower CBF values primarily in bilateral temporal lobes, ...
Journal of Magnetic Resonance ImagingPreibisch C, Sorg C, Forschler A, Grimmer T, Sax I, Wohlschlager AM, et al. Age-related cerebral perfusion changes in the parietal and temporal lobes measured by pulsed arterial spin labeling. J Magn Reson Imaging 2011; 34: 1295-302....
Eight out of 17 neonates (47%) had an abnormal on late MRI as performed and 7/20 neonates (35%) had an abnormal late MRI. CBF values in the basal ganglia and thalami (BGT) and temporal lobes were significantly higher on DOL4 than on DOL11. There were no significant differences ...
Increased craving also predicted increased rCBF from smoking satiety to abstinent conditions in regions including the frontal and occipital lobes, striatum and thalamus (Wang et al, 2007), suggesting increased neural activity in these regions underlies abstinence-induced cravings. Nicotine, in the ...
(b) Magnetic resonance (MR) perfusion images with three-dimensional pseudocontinuous arterial spin labeling (ASL) revealed marked hyperperfusion in the left posterior cortex (parietal, occipital, and posterior temporal lobes), postero-dorsal to the old hematoma in the left fronto-parietal lobe (white...
The orbital phases are denoted by colors or signs of π- orbital lobes. Fused lobes with the same color or sign are in-phase, and those with isolated (unfused) Colorants 2022, 1 95 lobes with different colors or signs are out-of-phase. In MO images, positive and negative signs have ...
