2023年11月4日 · These brain foci are important because they help doctors understand and take care of problems in your brain. Medical imaging utilizes several primary techniques, including magnetic resonance imaging (MRI), computed tomography (CT), and positron emission tomography (PET), to identify brain foci and understand their clinical implications.

2024年9月30日 · Brain foci (singular: focus) are small areas of abnormal signal intensity that show up on brain imaging scans. Think of them as tiny islands in the vast sea of neural tissue. These spots can vary in size, shape, and location, and they’re often detected during routine magnetic resonance imaging (MRI) scans.

2015年8月4日 · Foci are cells located in a specific organ of the body that are notably different from the surrounding cells. These differences are caused by mutation or other types of cellular damage, and they’re generally the first sign of a developing lesion, tumor or other disease.

This calculator will find either the equation of the ellipse from the given parameters or the center, foci, vertices (major vertices), co-vertices (minor vertices), (semi)major axis length, (semi)minor axis length, area, circumference, latera recta, length of the latera recta (focal width), focal parameter, eccentricity, linear eccentricity (foc...

Recurrence-free survival rates were significantly higher for patients with < 4 foci compared with ≥ 4 foci (100% vs 20%, respectively; p < 0.001). 5 Notably, the existing literature on this matter diverges not only on the results but also the inclusion criteria and the classification of tumors.

2025年2月16日 · Focal areas of signal intensity (FASI), also known as focal abnormal signal intensity or unidentified bright objects (UBO), are bright areas on T2-weighted images commonly identified in the basal ganglia (often the globus pallidus), thalamus, brainstem (pons), cerebellum, and subcortical white matter in children with neurofibromatosis type 1 (NF1).

在几何，焦点（focus或foci）（英国：/foʊkaɪ/，美国：/foʊsaɪ/）中，焦点是指构建曲线的特殊点。 例如，一个或两个焦点可用于定义圆锥截面，其四种类型是圆形，椭圆形，抛物线和双曲线。

2020年8月12日 · Foci are a common finding on breast MRI, yet there are limited data to guide their management, resulting in less certainty for radiologists reviewing the MRI. In this retrospective study of 200 eligible foci, outcomes of BI-RADS category 3 and 4 foci as well as features associated with malignancy were evaluated.

Necroinflammatory foci (arrows) are scattered in the hepatic lobule (hematoxylin and eosin staining). Portal inflammation in NAFLD/NASH is usually absent or mild, and consists mainly of lymphocytes. When portal inflammation is disproportionately severe, the possibility of concurrence of other liver diseases (such as hepatitis C and autoimmune ...
