BACKGROUND AND PURPOSE The purpose of radiosurgery of bAVMs is complete angiographic obliteration of its nidus. We assessed the diagnostic accuracy of 1.5T T2-weighted MR imaging and TOF-MRA images for detecting nidus obliteration after radiosurgery. MATERIALS AND METHODS The pre- and postradiosurgery MR images and DSA images from 120 patients who were radiosurgically treated for a bAVM were ...

 Abstract Background: The Gamma Knife Radiosurgery (GKR) is an established management option for Cerebral Ar-teriovenous Malformations (AVMS). Therapeutic benefits of radiosurgery for arteriovenous malformations are complete obliteration of nidus with minimal neurological deficit. Methods: Radiosurgery was performed between February 2003 and April 2010 at Kamraniye day clinic, Teh-ran, Iran, us...

A Cerebral Arteriovenous Malformation is an abnormal connection between arteries and veins. Normally the blood flows from arteries to veins through capillary bed. But patient having AVM, the capillary bed will be absent. The veins cannot handle the pressure of blood flowing from arteries to veins and it ruptures. The success of treatment by embolization in interventional Neuroradiolgy is highly...

intraepiphyseal location of an osteoid osteoma is extremely rare with few cases reported in the literature. they are often present with various atypical and nonspecific clinical features. synovitis of adjacent joint is common and along with chronic inflammation could be misinterpreted as rheumatoid arthritis. initial plain radiographs are often not diagnostic and further radiologic evaluation w...

Arteriovenous malformation nidus catheterization with a flow-directed catheter at times can be difficult owing to tortuosity of the intracranial vasculature and distal location of the nidus. Since January 1995, hydrophilic wire has been used in conjunction with the 1.8F flow-directed microcatheter in over 150 vessel embolizations with cyanoacrylate glue for brain and spinal arteriovenous malfor...

AIM Giant arteriovenous malformations (i.e., those greater than 6 cm maximum diameter or volume > 33 cc) are difficult to treat and often carry higher treatment morbidity and mortality rates. In our study, we reviewed the angiographic results and clinical outcomes for 11 patients with giant arteriovenous malformations who were treated between 1994 and 2012. MATERIAL AND METHODS The patients s...

Çoğunlukla başka bir nedenle yapılan radyolojik incelemelerde rastlantısal olarak saptananan benign osteojenik tümörlerden olan osteoid osteoma aktiviteden bağımsız, geceleri daha şiddetli ağrıya neden olur. Standart radyografiler lezyonu gösterebilir ancak nidusun gösterilmesi ve lezyonun yerinin kesin tespiti için bilgisayarlı tomografi (BT) gerekmektedir. Nidus adı verilen radyolusen alana s...
