“…A popular neuroimaging method used nowadays in the study of psychology is magnetic resonance imaging (MRI). MRI will be utilised to examine anatomical abnormalities in the brain and to evaluate cognitive abilities [3]. Functional magnetic resonance imaging (fMRI), a different set of imaging methods, is used to display temporally and spatially varied changes in brain metabolism.…”

This article is a comprehensive review of borderline personality disorder (BPD) based on the neuroimaging technique. The paper incorporated the etiology of BPD, the correlated brain structure and function abnormality of BPD found by neuroimaging techniques, influence of brain abnormality and recommendations for future research directions. The method used in the paper is to generalise results from pre-existing research and studies by reviewing the literature. The results and discussion section will focus on the comparison between BPD and non-BPD subjects, intending to highlight the most significant anatomical and functional abnormalities in the brain such as the hippocampus, the amygdala and the primary visual processing area. Furthermore, the impact of early trauma, and the connection between brain abnormalities and emotional dysregulation will be discussed in the paper. The suggestions and discussions section at the end will cover the current limitation of BPD neuroimaging research based on the selection bias on gender and provide directions for future research. The overall goal of the current study is to increase knowledge about BPD.

“…Anxiety is described as a state of emotional distress and inner turmoil, which may be manifested by nervous behavior and restlessness, muscular tension and other somatic complaints [ 22 – 24 ]. Anxiety-related sympathicotonic and claustrophobic reactions and some anxiety reduction protocols have been evaluated mainly for magnetic resonance imaging examinations [ 25 – 30 ]. The aim of this study is to investigate the impact of state anxiety (patient’s reaction to exam-related stress), trait anxiety (patient’s personality characteristic), and depression on direct patient motion during myocardial perfusion imaging.…”

BackgroundPatient motion during myocardial perfusion SPECT imaging (MPI) may be triggered by a patient’s physical and/or psychological discomfort. The aim of this study was to investigate the impact of state anxiety (patient’s reaction to exam-related stress), trait anxiety (patient’s personality characteristic) and depression on patient motion during MPI.MethodsAll patients that underwent MPI in our department in a six-month period were prospectively enrolled. One hundred eighty-three patients (45 females; 138 males) filled in the State-Trait Anxiety Inventory (STAI) and the Beck Depression Inventory (BDI), along with a short questionnaire regarding their age, height and weight, level of education in years, occupation, and marital status. Cardiovascular and other co-morbidity factors were also evaluated. Through inspection of raw data on cinematic display, the presence or absence of patient motion was registered and classified into mild, moderate and severe, for both phases involved in image acquisition.ResultsThe correlation of patient motion in the stress and delay phases of MPI and each of the other variables was investigated and the corresponding Pearson’s coefficients of association were calculated. The anxiety-motion (r = 0.43, P < 0.0001) and depression-motion (r = 0.32, P < 0.0001) correlation results were moderately strong and statistically significant for the female but not the male patients. All the other variables did not demonstrate any association with motion in MPI, except a weak correlation between age and motion in females (r = 0.23, P < 0.001).ConclusionsThe relationship between anxiety-motion and depression-motion identified in female patients represents the first supporting evidence of psychological discomfort as predisposing factor for patient motion during MPI.

3D scanning technologies are used to convert a physical model into digital 3D computer-aided design (CAD) file. This digital output is well used for designing and fabricating customised parts through additive manufacturing (AM) technologies. There is a need to identify the contemporary level of adoption of 3D scanning technology in the dental area. This structured literature review based research first tries to identify different types of scanning technologies and then the necessary steps as used to create a design and manufacture dental implant using the 3 D scanning. A large number of the relevant research papers on 3D scanning applications in dentistry are identified through Scopus and analysed using bibliometrics. This analysis indicates towards an increasing trend of research on 3D scanning applications in the field of dentistry. Different applications of this technology are discussed in the context of dentistry and observed that this technology create innovation in dental products for a dentistry lab. The dentist can take advantages of this technology towards designing custom teeth, crown, braces, dentures, veneers and aligner. 3D digital models also support teaching in dental education for better understanding and practice of the teeth anatomy. Along with the scanning of the complete denture of the patient, direct printing of the same is done by using AM technology produces denture which directly fits the mouth of the patient. It helps reduction of the complexity and production cycle time. 3D scanning technologies seem to have the potential for denture positioning and denture retention and improvement in existing dental implants.
