background: along with the prospers of scientific production there is a need for measuring and evaluation of university’ s scientific productions by means of accepted international indices to make comparison between academic institutions. this study aims to evaluate the scientific production of faculty members affiliated to shahid beheshti university of medical sciences (sbmus) in web of scienc...

Most existing genome-wide association analyses are cross-sectional, utilizing only phenotypic data at a single time point, e.g. baseline. On the other hand, longitudinal studies, such as Alzheimer's Disease Neuroimaging Initiative (ADNI), collect phenotypic information at multiple time points. In this article, as a case study, we conducted both longitudinal and cross-sectional analyses of the A...

BACKGROUND Optical coherence tomography (OCT) is a high-resolution intravascular imaging technique used in adults. We tested the hypothesis that OCT could identify coronary abnormalities not seen by angiography in children with a history of Kawasaki disease (KD) and pediatric heart transplant (TX) recipients. METHODS AND RESULTS Patients with KD and TX recipients were evaluated between Decemb...

BACKGROUND AND PURPOSE Evaluation of alar traumatic injuries by using MR imaging is frequently performed. This study investigates the variability of morphology and signal intensity of alar ligaments in healthy volunteers so that pathology can be more accurately defined. MATERIALS AND METHODS Fifty healthy volunteers were examined on a 1.5T MR imaging scanner with 2-mm PD-weighted sequences in...

[Purpose] The primary purpose of this study was to evaluate the intraclass correlation coefficient (ICC) in obtaining the cross-sectional area of the lumbar multifidus muscles in patients with chronic low back pain (LBP) at rest and during contractions facilitated by PNF patterns by ultrasound imaging. [Subjects] The subjects were 15 (4 males, 11 females) who had chronic LBP on one side for mor...

Optical scanning holography is a powerful holographic recording technique in which only a single two-dimensional scan is needed to record three-dimensional information. As in standard digital holography, for the reconstruction of a sectional image, the resulting data must then be postprocessed to obtain sectional content. We propose a blind sectional image reconstruction technique to automate t...

INTRODUCTION Children with cleft lip and palate (CLP) are known to have airway problems. Previous studies have shown that individuals with CLP have a 30% reduction in nasal airway size compared to non-cleft controls. No reports have been found on cross-sectional area and volume of the pharyngeal airway in clefts. Introduction of Cone-Beam CT (CBCT) and imaging software has facilitated generatio...

Purpose: Nasal cavity may contain wide variety of masses within, that differs this organ from the rest of the body. Primary nasal cavity masses consist of 0.2% 0.8% of all malignancies. This paper aims to emphasize the main characteristics of different nasal cavity masses on cross-sectional images which may cause symptoms varying from simple nasal obstruction to metastatic invasion. We tried to...

UNLABELLED The objective of this study was to determine whether posttherapy (131)I SPECT/CT changed the need for additional cross-sectional imaging or modified the American Thyroid Association risk of recurrence classification. We performed planar imaging and SPECT/CT in a consecutive series of patients after (131)I therapy. METHODS Planar imaging and SPECT/CT were performed on 148 consecutiv...
