Judging colloid tumour in early days has new laws to put the curative effect fruit
It is reported ' Reporter Kuang YuanShen) Whether low rank colloid tumour or high-level colloid tumour, adopt the technology of the formation of image of disperse tensor of the magnetic resonance, carry on the anisotropic mark (FA value) to the district organization of interest of the focus Measurement is calculated, learn the assessing value to carry on relevance analysis with the clinical and regular image, can judge to patient's radiotherapy curative effect, its accuracy is 92.7%, it finds condition progress sensitiveness and specificity of the case are 81.9% and 96.2% respectively in early days. This research of finishing of subsidiary colloid tumour rescue center Professor Jiang Tao, nerve of Beijing God Temple Hospital department of neurosurgery of Capital University of Medical Sciences radiate Li ShaoWu, director of centre,ing etc., assessing colloid tumour clinically and putting the curative effect fruit opens up a new diagnosis route. Colloid tumour is malignant tumour in the most common cranium, have characteristics such as high mortality and hitting the time of surviving of location short,etc.. Previously main the intersection of basis and the intersection of tumour and diameter at the image treat, ' Volume) Change last curative effect,after having often stagnat and subjective judgement limitation. In order to explore effective curative effect judges the method, researchers employ disperse technology and variance of the magnetic resonance, analyze sensitiveness and specificity of the number value variable among different therapeutic effect patients. It verifies the curative effect of some radiotherapy to send a postoperative colloid tumour patient newly through observing 37, apparent disperse coefficient (ADC) The value is presented and defeated by with the cell density of local organization of tumour relevantly, and some anisotropic mark values (FA) The cell density organized with tumour is the positive correlation. At the same time, employ experimenter's working characteristic contours to analyze that find, accumulate ADC and change the percentage to predicting patient's radiotherapy of colloid tumour reflects that there is better diagnosis value in early days. According to the introduction of Li ShaoWu, magnetic the intersection of resonance and the intersection of disperse and formation of image technology fast to scan, carry on the apparent new technology that looks like to micro sports and hot sport characteristics, son of moisture, with magnetic resonance. Through commenting on disperse intensity and disperse direction of the free moisture son of white matter of brain, can quantify pathology and function information of tumour and structure around; Anisotropism that can move according to the sub disperse of inner moisture of brain white matter fiber at the same time, clear to reveal that because it is ischemic to organize, intravital tissue slight change and infiltration intensity to the area around of tumour cell at the cell level that some necrosis, cell hyperplasia,etc. cause, thus what made to patient's radiotherapy curative effect of colloid tumour was judged in early days.
