OBJECTIVE To evaluate the prevalence of vulnerable blood vessels around cervical nerve roots before cervical nerve root block in the clinical setting. METHODS This retrospective study included 74 patients with cervical radiculopathy who received an ultrasonography-guided nerve block at an outpatient clinic from July 2012 to July 2014. Before actual injection of the steroid was performed, we e...

Computerized segmentation of retinal vessels can help doctors discover diabetic retinopathy, Retinal Tear and Detachment. Because the anatomy is complicated changing, automated vessel still a difficult task. The Expectation-Maximization approach for vascular proposed in this paper, which uses matched filter (MF) that combines Mask based Blood Vessels Extraction with global image threshold to ex...

detecting blood vessels is an important task in retinal image analysis.  the task is more challenging with the presence of bright and dark lesions in retinal images. here, a method is proposed to detect vessels in both normal and abnormal retinal fundus images based on their linear features. first, the negative impact of bright lesions is reduced by using k-means segmentation in a perceptive sp...

background neuropathy is one of the most complications of diabetes that may be associated with changes in the structure and function of the basement membranes in nerves. laminin is one of the most important components of basement membranes in sciatic nerve. objectives in this study, the protective effects of alpha lipoic acid (ala) as an antioxidant agent on blood glucose level, body weight and...

the investigation and determination of the significance of neovascularization in the progression of soft tissue sarcoma is currently of increasing clinical importance. microvessel density is the morphologic evidence of neoangiogenesis in the process of malignant progression of sarcomata. this brief review of the markers commonly used in clinical practice was undertaken to determine the validity...

in the present study, pancreas glands in mehraban breed of female sheep were histomorphometricallystudied in four different age groups included: fetus, newborn, sexually mature and old ages. the results ofhistomorphometrical analysis with regard to frequency and percentage of parenchymal and stromal structures such as, exocrine secretory units, secretory ducts, blood vessels, islets of langerha...

The fusiform face area (FFA) is known to play a pivotal role in face processing. The FFA is located in the ventral region, at the base of the brain, through which large blood vessels run. The location of the FFA via functional MRI (fMRI) may be influenced by these large blood vessels. Responses of large blood vessels may not exactly correspond to neuronal activity in a target area, because they...

Retina images are obtained from the fundus camera and graded by skilled professionals. However there is considerable shortage of expert observers has encouraged computer assisted monitoring. Evaluation of blood vessels network plays an important task in a variety of medical diagnosis. Manifestations of numerous vascular disorders, such as diabetic retinopathy, depend on detection of the blood v...
