This study evaluated a relaxation intervention designed to prevent anxiety during magnetic resonance imaging (MRI), and assessed the development of fears in patients who felt anxious during the procedure. Patients were assigned to a control condition (no intervention; n = 52), relaxation before the scan (n = 44), or relaxation before and during the scan (n = 43). Compared to the control group, patients who practised relaxation showed reduced anxiety during the scan. Seven months or more after undergoing MRI, there was a positive correlation between anxiety experienced during the scan and the development of MRI-related fears. The intervention did not prevent the development of MRI-related fears at follow-up.

Accurate and early diagnosis of Depression and Anxiety is met with the challenge of comorbid presentations and the neglect of the basic disturbances of self in current diagnostic criteria. Here, we review studies employing functional magnetic resonance imaging (fMRI) with self-based tasks in major depressive disorder (MDD) and anxiety disorders (AD) to determine the transdiagnostic and differential-diagnostic applicability of neural markers related to the self. This systematic review identified three main findings: (I) Large-scale brain-wide changes related to self-dysfunction overlap significantly between MDD and AD.

Social comparisons are a core feature of human life. Theories posit that social comparisons play a critical role in depression and social anxiety triggering negative evaluations about the self, as well as negative emotions. We investigated the neural basis of social comparisons in participants with depression and/or social anxiety (MD-SA, n=56) and healthy controls (n=47) using functional magnetic resonance imaging (fMRI).

Background: Anxiety is a common comorbidity in patients with Crohn's disease (CD). Data on the imaging characteristics of brain microstructure and cerebral perfusion in CD with anxiety are limited.
Aim: To compare the imaging characteristics of brain microstructure and cerebral perfusion among CD patients with or without anxiety and healthy individuals.

At least 227 combinations of symptoms meet the criteria for Major Depressive Disorder (MDD). However, in clinical practice, patients consistently present symptoms in a regular rather than random manner, and the neural basis underlying the MDD subtypes remains unclear. To help clarify the neural basis, patients with MDD were clustered by symptom combinations to investigate the neural underpinning of each subtype using functional resonance imaging (fMRI).

The present study investigated the impact of GABAergic signaling and miRNA expression on glioblastoma multiforme (GBM) growth within the medial prefrontal cortex (mPFC) and its associated cognitive and emotional impairments. The implantation of C6 cells into the mPFC induced GBM in this brain region (referred to as the mPFC-GBM) in male Wistar rats via stereotaxic surgery, as confirmed by Magnetic Resonance Imaging (MRI), and Hematoxylin and Eosin (H&E) staining. Repeated microinjections of muscimol, a potent GABA receptor agonist, directly into the mPFC-GBM (1 µg/rat/2.
