BACKGROUND AND PURPOSE Previous studies have shown motor impairment after a stroke relates to lesion size and location, but unexplained variability in recovery still exists. In this study, we used lesion-mapping techniques in combination with diffusion tensor imaging to quantitatively test the hypothesis that motor recovery in patients with chronic stroke is inversely related to the proportion ...

PURPOSE To determine the involvement of sympathetic activity in choroidal neovascularization (CNV) using laser-induced CNV in a mouse model. METHODS We investigated changes in the proportions of intraocular lymphocytes, granulocytes, and three macrophage subtypes (Ly6Chi, Ly6Cint, and Ly6Clo) after laser injury in mice using flow cytometry, and evaluated CNV lesion size in mice lacking inflam...

BACKGROUND It is important to increase lesion size to improve the success rate for radiofrequency ablation of ischemic ventricular tachycardia. This study of radiofrequency ablation, with adjustment of power to approach a preset target temperature, ie, temperature-controlled ablation, explores the effect of catheter-tip length, ablation site, and convective cooling on lesion dimensions. METHO...

BACKGROUND The purpose of this study was to describe a system and method for creating, visualizing, and monitoring cardiac radiofrequency ablation (RFA) therapy during magnetic resonance imaging (MRI). METHODS AND RESULTS RFA was performed in the right ventricular apex of 6 healthy mongrel dogs with a custom 7F nonmagnetic ablation catheter (4-mm electrode) in a newly developed real-time inte...

Case 1: A 50-year-old woman presents for excision of lesion along right nasolabial fold, which has been present for 2 years and has been increasing in size. Patient describes the lesion as itchy and denies pain, bleeding, or other symptoms. Case 2: A 47-year-old man presents for excision of lesion along right nasolabial fold, which has been present for 1.5 years and has been increasing in size....

Background Undifferentiated type of early gastric cancer (U-EGC) is included among the expanded indications endoscopic submucosal dissection (ESD); however, rate curative resection remains unsatisfactory. Endoscopists predict probability by considering size and shape lesion whether ulcers are present or not. The location lesion, indicating likely technical difficulty, also considered. Objective...

introduction: bacterial infection of tooth pulp can progress into periapical diseases. root canal treatment has been established as the best treatment. in cases of failure, nonsurgical retreatment of teeth is preferred to surgical procedure and extraction. materials & methods: in this historical cohort study, 104 permanent teeth with apical lesion were treated during 2002-2008. all teeth showed...

BACKGROUND AND PURPOSE Although the number of enhancing lesions is the typical outcome measure of choice in clinical trials in MS, a potentially more sensitive and statistically more powerful outcome measure is the volume of enhancing lesions. In this study, we assessed the distribution and statistical power of the volume of enhancing brain lesions as an outcome measure by means of their requir...

Ocular surface squamous neoplasia (OSSN) is the most common type of ocular tumour. An eighty-year-old man with an elevated lesion in right eye was diagnosed to have OSSN. 1% topical 5-FU started as intermittent treatment. Examination during each visit showed consistent reduction size lesion. The patient complete regression no recurrence following treatment at 3 months from presentation. Tropica...

The size of a lesion is a feature often used in computer-aided detection systems for classification between benign and malignant lesions. However, size of a lesion presented by its area might not be as reliable as volume of a lesion. Volume is more independent of the view (CC or MLO) since it represents three dimensional information, whereas area refers only to the projection of a lesion on a t...
