S erious and chronic childhood psychiatric disorders have long been assumed to reflect relatively subtle abnormalities of brain development. Although diagnostic brain imaging is well established in pediatric neurology, it has not yet permitted quantitative assessment of brain abnormalities in children with psychiatric illnesses. Recent advances in brain magnetic resonance imaging (MRI) allow re...

Background and Purpose. In pyogenic brain abscess, hemorrhage in the walls is considered exceptional. Recently, hemorrhagic changes in the walls of pyogenic abscess have been demonstrated on susceptibility weighted imaging with 3T MRI. Here, we report hemorrhagic changes in the walls of pyogenic brain abscess on susceptibility weighted imaging with 1.5T MRI. Method. MRI of brain was done using ...

Diffusion MRI has been used worldwide to produce images of brain tissue structure and connectivity, in the normal and diseased brain. Diffusion MRI has revolutionized the management of acute brain ischemia (stroke), saving life of many patients and sparing them significant disabilities. In addition to stroke, diffusion MRI is now widely used for the detection of cancers and metastases (breast, ...

Effective, precise and consistent brain cortical tissue segmentation from magnetic resonance (MR) images is one of the most prominent issues in many applications of medical image processing. These applications include surgical planning (Kikinis et al., 1996), surgery navigation (Grimson et al., 1997), multimodality image registration (Saeed, 1998), abnormality detection (Rusinek et al., 1991), ...

We investigated the safety and clinical applicability of 7.0 Tesla (T) brain magnetic resonance imaging (MRI) in patients with brain tumors. Twenty-four patients with intraaxial or extraaxial brain tumors were enrolled in this study. 7.0T MRIs of T2*-weighted axial and T1-weighted coronal or sagittal images were obtained and compared with 1.5T brain MRIs. The T2*-weighted images from 7.0T brain...

UNLABELLED Central precocious puberty may result from organic brain lesions, but is most frequently of idiopathic origin. Clinical or biochemical factors which could predict a pathological brain MRI in girls with CPP have been searched for. With the recent decline in age at pubertal onset among US and European girls, it has been suggested that only girls with CPP below 6 years of age should hav...

Carotid artery thrombosis and concomitant brain infarction after blunt trauma are rare conditions. We report a 34-year-old woman with multiple traumas due to pedestrian car accident. At the time of initial visiting, she was somnolent and her Glasgow coma scale (GCS) score was 14. Initial vital signs (V/S) and brain computed tomography (CT) scan were normal. One day after admission to the emerge...

abstract the intraparenchymal schwannomas are very rare tumors with only 52 reported cases . we describe a 38 years old man with eight months history of poorly controlled seizures despite of medical therapy. on brain ct scan a 1.5 x 1.5 cm hypodense enhancing lesion was seen in right posterior-inferior frontal lobe. on brain mri the lesion was hypointense in t1 and hyperintense in t2 with homog...

purpose: to report a patient with an intraocular lymphoma with history of treated brain lymphoma. case report: a 45-year-old female was referred with moderate chronic intermediate uveitis of both eyes that was unresponsive to medications. she had history of treated brain lymphoma with chemotherapy and radiotherapy 6 years before presentation. systemic workup, laboratory evaluation, brain and or...
