background and purpose: the problematic reduction of civic engagement in local communities of khuzestan province in the southwest of iran has became a serious issue for research in social planning and policy making. efforts have been made to study the risk factors as the deterrents to engaging in the society. methods: this study aims to investigate the factors influencing civic engagement among...

We report the MR imaging findings in two cases of nasolabial cysts. Demonstration of their extraosseous location with cross-sectional imaging should prevent confusion with maxillary cysts and obviate unwarranted dental or maxillary surgery.

OBJECTIVES Although rectal cancer is by far and large the most common pathology involving the rectum that needs imaging, there are many other important but less common pathological conditions affecting anorectal region. The objective of this pictorial review is to discuss the cross-sectional imaging features of less common anorectal and perirectal diseases. RESULTS Although a specific histolo...

Cystic lesions of the pancreas are increasingly being recognized due to the widespread use of cross-sectional imaging. The initial evaluation of a pancreatic cyst should be directed toward exclusion of a pseudocyst. Patients with pseudocysts generally have a history of acute or chronic pancreatitis, whereas those with cystic tumors most often lack such a history. Several types of cystic lesions...

Recent imaging studies have suggested that developmental changes may parallel aspects of adult learning in cortical activation becoming less diffuse and more focal over time. However, while adult learning studies examine changes within subjects, developmental findings have been based on cross-sectional samples and even comparisons across studies. Here, we used functional MRI in children to test...

Study Design Cross-sectional study. Background Findings of fat infiltration in cervical spine multifidus, as a sign of degenerative morphometric changes due to whiplash injury, need to be verified. Objectives To develop a method using water/fat magnetic resonance imaging (MRI) to investigate fat infiltration and cross-sectional area of multifidus muscle in individuals with whiplash-associated d...

Radiotherapy for esophageal cancer relies on cross-sectional imaging to identify the entire extent of tumor. Rarely, the exact limits of the tumor may be radiologically occult. Lipiodol is a contrast agent which has been used successfully to mark cancers of the bladder and lung for radiotherapy and surgical resection. We report a patient with an adenocarcinoma of the gastroesophageal junction w...

Cross-sectional imaging has demonstrated an increasing role in the evaluation of the orbits and the periorbital structures. The case presented in this article demonstrates the rare finding of a dacryolith by CT. To our knowledge, little has been reported on cross-sectional imaging characteristics of this entity in the recent radiologic literature. We demonstrated that CT can be a useful tool in...

An endoscopic optical coherence tomography (OCT) system based on a microelectromechanical mirror to facilitate lateral light scanning is described. The front-view OCT scope, adapted to the instrument channel of a commercial endoscopic sheath, allows real-time cross-sectional imaging of living biological tissue via direct endoscopic visual guidance. The transverse and axial resolutions of the OC...

Primary cortical areas for motor, sensory and sensitive functions are localized in certain areas of the brain cortex. In clinical practice, cross sectional imaging (computer tomography and magnetic resonance) is wildy used for diagnostics purpose, treatment planning and follow up of the patients. Accurate orientation in brain structures is necessary for the evaluation of radiological images. Th...
