BACKGROUND AND PURPOSE Stroke is a major cause of cognitive impairment and dementia in adults, however the role of the ischemic lesions themselves, on top of other risk factors known in the elderly, remains controversial. This study used structural equation modeling to determine the respective impact of the new ischemic lesions' volume, preexisting white matter lesions and white matter integrit...

BACKGROUND AND PURPOSE Multiple sclerosis (MS) is the most common inflammatory disease of the central nervous system and manifests both physical and neurocognitive disabilities. Although predominantly a disease of the white matter, MS is also characterized by lesions in the gray matter. Previous pathologic studies have found that cortical and deep gray matter lesions comprised 5% and 4%, respec...

White-matter lesion count and volume estimation are key to the diagnosis and monitoring of multiple sclerosis (MS). Automated MS lesion segmentation methods that have been proposed in the past 20 years reach their limits when applied to patients in early disease stages characterized by low lesion load and small lesions. We propose an algorithm to automatically assess MS lesion load (number and ...

Surgical repair of a Bankart lesion requires thorough recognition of the capsulolabral attachment and adequate visualization for suture anchor repair. The glenoid labrum usually detaches from its capsule and bony attachment anteriorly and inferiorly; however, the labral and capsule detachment can sometimes extend beyond this zone of injury. Identification and repair may require additional viewi...

PURPOSE To prospectively evaluate the accuracy of three-dimensional (3D) sonoelastographic imaging, relative to that of gray-scale ultrasonography (US), in the in vitro detection of prostate cancer. MATERIALS AND METHODS The study was approved by the institutional review board and was HIPAA compliant. Informed consent was obtained from all patients. Nineteen prostatectomy specimens from patie...

Background: Diabetic nephropathy is one of the cause of the end stage of renal disease (ESRD). Hyperglicemia activate intrarenal Renin-Angiotensin system and highly AngiotensinII is produced locally in glomeruli. In this research AT1(Angiotensin type 1) receptors blocked by Losartan and effects of this drug in inhibition of renal structural lesions were assessed quantitatively. Materials & me...

hepatic inflammatory pseudotumor (ipt) is a rare non-neoplastic process of unknown etiology, generally following a benign inflammatory condition. it is often mistaken as an either primary or metastatic malignancy in imaging studies. we report a 48 year-old female with numerous target lesions (2-4 cm) seen on high resolution ultrasound, spiral ct scan, and mri in all liver lobes compatible with ...

introduction: idiopathic osteosclerosis is a common radiopaque lesion in the jaw bones, which is asymptomatic and usually detected accidentally in various radiographs. the purpose of this study was to determine the radiographic features of idiopathic osteosclerosis in the jawbones of patients referring to the maxillofacial radiology center of mashhad dental faculty. methods: in this descriptive...

purpose: to determine the prevalence of various types of conjunctival lesions, at a tertiary ophthalmic center in fars province, south of iran. methods: histopathologic slides and medical records of conjunctival lesions submitted to the pathology department of khalili hospital, shiraz, iran was reviewed from april, 2009 to july, 2013. the histopathologic diagnoses were categorized into benign, ...

the possibility that infectious agents may trigger a cascade of reactions leading to inflammation, atherogenesis and vascular thrombotic events has recently been raised. chlamydia pneumoniae is an infectious agent that has received the most attention with respect to coronary artery disease (cad). to determine the relationship between c. pneumoniae and cad, a case control study was conducted on ...
