X line check to explicit bone tumor property, category and scope and decision's curing policy can provide worthy data, is a bone tumor important check method.
However the X line slice is only the projection of bone tumor, the X line of bone tumor expresses Heng not to settle and need to closely combine clinical performance and pathology check, then can make an accurate diagnosis.
Positive bone tumor appearance rule, with surroundings normal bone organization boundary clear, with harden side for boundary, bone skin the quality become thin because of inflation, but still keep complete, have no periosteum reaction, the image of the malignant tumor anomaly, the edge is unclear and dissolve a bone phenomenon more obvious, bone substance break, become thin, split, imperfection, delivered sex malignant tumor to often appear periosteum reaction at first, its shape can present sunlight emanation-like in shape, spring onion skin kind and Codman triangle.
The X line slice can provide for the doctor concerning the tumor to be taken bad process four informations:
(A)the position of bone tumor if the tumor can be located on bone Mao as well as be located on to do bone Mao to carry, can be located on a long bone, can also be located on a flat even bone;The tumor that the teenager bone Mao takes place should consider the cartilage female cell lump first, but adult above-mentioned bone Mao the tumor of the department should consider for the bone big and small afterbirth lump.
(Two)the tumor has to the influence tumor and host bone boundary of host bone without gradually sex is the initial factor that makes sure a pathological changes property, the boundary is clear enunciation tumor growth slow-moving and gradually sex is weak.Whereas, the boundary is misty then express tumor gradually sex is strong.
(Three)host to the reaction host of tumor always the dint diagram exterminate tumor and wraps up it, the formation fiber organization wraps a film, growth rapid tumor can gradually with break this kind of reaction bone to wrap a film, but just in the tumor of a carry or the both ends can see cripple remaining of this kind of pack of film, usually the performance be triangle for Codman.
(Four)the density bone organization of tumor organization develops in if have any density variety, all can doubt that that organization is sick to change, some tumors in order to dissolve a bone sexually transmitted disease and change, like the bone big and small afterbirth lump, but some change for ossification sexually transmitted disease , ossification anomaly or is snowflake-like in shape, like blood relationship lump, cartilage tumor.
Occurrence's tumor in parts, such as pelvis and spinal column...etc., when the common X-ray slice can not nicely show the CT scans, super B, MRI, ECT etc. is new to develop a technique in aid of judge the part and scope of clear tumor.
The bone scans to namely display to deliver at first when common X-ray hasn't had a masculine gender change, after the existence of the hair bone tumor.Should optionally make to the suspicious 99 Mao etc. of the bone scan.
