Performance evaluation of spatial fuzzy C-means clustering algorithm on GPU for image segmentation.

Image processing by segmentation technique is an important phase in medical imaging such as MRI. Its objective is to analyze the different tissues in human body. In research area, Fuzzy set is one of the most successful techniques that guarantees a robust classification.

Differentiation of true transient ischemic attack versus transient ischemic attack mimics.

Background: Previous literatures have shown a transient ischemic attack (TIA) mimic rate of 9-31%. We aimed to ascertain the proportion of stroke mimics amongst suspected TIA patients.

Methods: A prospective observational study was performed in Ghaem Hospital, Mashhad, Iran during 2012-2013.

Laypersons' esthetic perception of various computer-generated diastemas: a pilot study.

Statement Of Problem: Managing excess anterior spacing is a common problem in dental practice. During orthodontic or restorative treatment planning, clinicians must decide how to distribute this space. However, few reports are available in the dental literature about the attractiveness and esthetic impact of anterior spaces other than midline diastemas.

Safety assessment of anticoagulation therapy in patients with hemorrhagic cerebral venous thrombosis.

Background: Anticoagulation therapy is a routine treatment in patients with hemorrhagic cerebral venous thrombosis (CVT). However, fear of hemorrhagic complications and deterioration course following anticoagulation often disturbs the responsible physician.

Methods: This was a Prospective observational study on consecutive CVT patients with hemorrhagic venous infarction or subarachnoid hemorrhage (SAH) admitted in Ghaem Hospital, Mashhad, Iran, during 2006-2012.
