| 摘 要： | 目的．应用高分辨率ＣＴ（ＨＲＣＴ）扫描方法，增加对头颅腔隙梗塞诊断的可靠性．材料和方法：对临床疑有腔隙的病人在基底节区及可疑部位加用ＨＲＣＴ扫描，遇到腔隙病灶与像素颗粒难以区分时，在相同层面或上下１～２ｍｍ处做ＨＲＣＴ扫描．结果：有２０８例常规ＣＴ正常的病例中发现了腔隙灶，在遇到的３２０例不易诊断的可疑病灶中，经ＨＲＣＴ确诊的真正腔隙灶８９例，伪腔隙（像素）２３１例，同时发现对正常腔组织结构的显示要较常规ＣＴ优越得多，结论：ＨＲＣＴ不仅能提高腔隙梗塞的诊断率，还能辨别伪腔隙是弥补常规ＣＴ对腔隙诊断不足的较好手段。

| Abstract: | Purpose : To use HRCT to increase the diagnostic reability of lacuna infarction of brain. Materials and methods: HRCT were used to the basal ganglion or suspected areae in patients with lacuna suspected clinically. HRCT were performed at the same layer or 1~2 mm above or below this layer when lacuna lesions were difficult to distinguish from image point grains. Results:In 208 patients lacuna lesions were found in conventional CT In 320 cases with suspected lesions, he lacuna lesions and false ones (image point grains) were diagnosed with HRCT in 89 and 231 cases respectively. In addition. the HRCT images of normal brain structure were more clear compared to those obtained in conventional CT Conclusion: Not only HRCT can increase the diagnostic rate of lacuna infarction of brain. but also distinguish the false lacuna,HRCT is a better technique that complements the insufficiency of conventional CT in the diagnosis or lacuna. |
