Unilateral Blindness as the Only Finding in a Patient with High Flow Carotid-Cavernous Fistula
The authors reported a patient with unilateral blindness of the left eye after trauma. Apart from paralysis of the 4th cranial nerve and mild optic nerve edema, there was no structural problem during the ophthalmologic examination. Brain CT scan, CT angiography and MRI demonstrated aneurysm in the left pericavernous region. The patient underwent angiography for coiling of the aneurysm, which detected large carotid cavernous fistula (CCF) mainly draining into the petrous sinus. Therapeutic embolization was performed with balloon and the CCF vanished completely. The most important points of this case are the blindness without exophthalmia as the only presentation of CCF which has not been reported as the only symptom and failure of CT-angiography and MRI evaluation for the diagnosis of CCF
Carotid Doppler Ultrasonography in Preoperative Assessment of Coronary Artery Bypass Graft Surgery in an Iranian Population: Association Between Atherosclerosis Risk Factors and Carotid Stenosis
Among all cardiovascular risk factors, it seems that serum HDL, smoking, left main coronary stenosis and hypertension could be associated with significant carotid artery stenosis in CABG candidates
The Effect of Aging on Resting-State Brain Function: An fMRI Study
multi-method analysis of functional connectivity data may be critical to capture the full effect of aging on the health of brain networks
Evaluation of hydrogen peroxide- enhanced endoanal ultrasound in detecting the internal orifice and type of fistula-in-ano
Hydrogen peroxide-enhanced EUS is a suitable method for detecting the internal orifice of anal fistulas. It can be used for detecting trans-sphincteric fistulas, which are the most common type
Correlation of Lund Mackay and SNOT 20 Before and After Functional Endoscopic Sinus Surgery (FESS): Does the Baseline Data Predict the Response Rate?
The outcome of FESS in patients with CRS is moderately related to primary symptoms according to SNOT-20 as well as the Lund-Mackay radiologic score

Reliability of determination of bony landmarks of the distal femur on mr images and mri based 3d models
This study assessed the reliability of identifying knee epicondyle landmarks on 2D MRI and 3D MRI-based models. Both intra- and inter-observer reliability were excellent (ICC > 0.97), with small measurement errors. The findings confirm that landmark determination using MRI and 3D models is highly reliable.
Uncommon Patterns of Intracranial Aneurysms: A Pictorial Essay
“Landmark identification on 2D MRI and 3D MRI-based knee models showed excellent reliability (ICC > 0.97) with minimal errors.”
Improvement of White Matter Fiber Tracking Based on Diffusion-Tensor MR Imaging Data Using Modified Speed Functions
White matter tractography is a non-invasive method, which reconstructs three-dimensional trajectories of the brain tracts using diffusion-tensor imaging (DTI) data. Due to the partial volume effect of DTI data, some of tractography algorithms are unable to follow the correct pathways after the crossing and branching regions. The main challenge for tractography methods has been the ability to detect these regions. Fast marching techniques are capable of tracking the fibers with wide spreading
