COMBINED IMAGING DIAGNOSIS OF PAROTID MASSES

Computed tomography (CT), ultrasonography, sialography, and 99mTc scintigraphy were applied before operation to 108 patients with parotid masses. The results of each technique and the combined study of them were compared with the pathological diagnosis. Ultrasonography was found to be a very effective diagnostic aid in determining the presence of space-occupying lesion in the parotid. CT was the best technique to provide adequately reliable informations regarding the location of the tumor and the relationship between tumor and surrounding tissues. For diagnosing the nature of tumors, ultrasonography combined with sialography was reliable. 99mTc scintigraphy was better than other techniques in diagnosis of adenolymphoma. The diagnostic accuracy of combined diagnosis (90.7%) was higher than those of ultrasonography (83%), CT (80.5%), sialography (79%), and 99mTc scintigraphy (13.9%) alone. The advantage of combined diagnosis was particularly obvious for the diagnosis of low-grade malignant tumors.

子宫附件肿块B超显像与病理检查符合率研究

我科对88例患者的子宫附件肿块(共108个)进行术前B 超诊断,与开腹时情况,术后肿块标本检查所见及病理切片对照.其结果是术前超声诊断与病理分类完全符合的48个(44.4%);基本符合的41个(38.0%);不符合的13个(12.0%);另超声诊断假阴性6个(5.6%).凡附件肿块有特征性大体形态改变的,其声像图也有特征性表现,可据此声像图改变做出病理诊断。如成熟的囊性畸胎瘤、多房性粘液性囊腺瘤.巧克力囊肿和恶性卵巢肿瘤等.

腮腺区肿块的影像学诊断

腮腺区肿块在临床颇为常见,手术治疗前必须了解肿块的范围和性质,才能制订合理的手术方案。本研究应用现代医学影像学的各种手段,在以下六个方面进行了研究: 1.对132例患者作超声检查,将腮腺肿瘤的声像图分为五型,分别以良性肿瘤、具侵袭性的良性肿瘤、低度恶性肿瘤、恶性肿瘤及腺淋巴瘤为多见,将诊断结果与术后病理相对照,诊断符合率为     

彩色多普勒在原发性下肢深静脉瓣功能不全检查中的应用

作者应用彩色多普勒检查了19例(27条)原发性下肢深静脉瓣功能不全患者和19例(38条)正常受试者。结果显示27条下肢深静脉瓣功能不全有血液返流征,在正常受试者中,仅有2条下肢深静脉出现返流征,二者比较,相差极显著,P<0.001(x~2=57.31)。彩色多普勒检查具有无创伤性、简便、快速等特点,因此,它可以广泛应用于临床检查。     

小儿颅脑的超声断层检查

作者利用超声断层的方法,以前囱作“声窗”(Acoustic window)对100例早产儿、新生儿及其它前囱开大的婴幼儿颅脑进行观察。作者使用的是机械扇形扫查探头,工作频率5.0MHz,6个月以上幼儿有时用3.0MHz 的探头。作者提出如下8个切面可作为小儿颅脑检查的基准切面:(1)经侧脑室前角切面:可显示额
