病灶

The measurements of RI and PI of the four groups were recorded respectively and the comparition between benign and malignant neoplasms was made by applying Doppler quantitative analysis.

病灶的二维图像特征，记录其彩色血流的检出率及多普勒定量分析数据，对良恶性肿瘤进行比较。

With this analysis of MR parametric histogram, we demonstrated that there existed significant differences of parametric amplitude, compartmental exchange rate kout and maximal signal enhancement between benign and malignant breast lesions.

我们的研究结果显示在良性恶性乳房病灶及肿瘤间，包括辐度、组织间交换速率及最大讯号显影度，均存在明显差异。

The high signal in the corticospinal tract on T2-weighted images became less marked with progression of the disease in one patient.

在我们的研究中，一例ALS患者T2像上皮质脊髓束的高信号病灶随病程进展而逐渐消失。

High signal intensity in the lateral part, which corresponded to the lateral corticospinal tract of the cervical spinal cord was seen on T2 weighted images in 7 patients (cases 1, 2, 4, 6 and 11-13)(Fig.3 b).

在所有21例ALS患者中有7例患者（病例1、2、4、6、11~13）在T2像上于颈髓的皮质脊髓侧束区可见高信号病灶。

Further study is required to establish whether the high signal intensity in the intracranial corticospinal tract on T1 weighted images correlates with the severity of the upper motor neurone

但，仍需要进一步研究以明确T1像上颅内皮质脊髓束的高信号改变是否与上运动神经元病灶的严重性相关。

Segawa[10] also demonstrated high signal in the intracranial corticospinal tract on T1-weighted images in patients with ALS but not in normal and disease controls, as in the present study.

ALS患者在T1像上于颅内皮质脊髓束走行区可见高信号病灶，但正常人、其他神经疾病患者在T1像上却未见此改变。

In addition, five patients with ALS with severe upper motor neurone signs such as spastic paraparesis showed high signal in the intracranial corticospinal tract on T1-weighted images as well as on T2- and PD-weighted images.

另外，5例表现出严重的上运动神经元症状体征的ALS患者，在T1、T2、PdWI这3像上，都于颅内皮质脊髓束走行区表现出高信号病灶。

Ulcerative type: this lesion presents a flat appearance at its beginning and later develops into a typical crateriform ulcer with depressed centre and firm and raised periphery on a nodula base.

溃疡型：这种病灶初期呈现出扁平状，后来发展成中部坏死、边缘坚固隆起在结节底部上的典型的火山口样溃疡。

The standard of the well contr ol of the disease included:(1) the ocular tumor shrank or even disappeared, and the tumor had creamlike changes or calcification and cicatrisation;(2) no oc u lar tumor recurrence in patients who had undergone enucleation;(3) no metastasi s found in the followup period.

病情得到良好控制的标准为：（1）眼部肿瘤缩小乃至消失，肿瘤病灶呈软乳酪样改变或出现钙化和瘢痕化；（2）眼球摘除者未出现眼眶肿瘤复发；（3）临床检查未见肿瘤转移。

Results CT displayed the lesions located in the bladder neck and triangle area in 7 cases, in the right anterior wall in 1 cases, involve the entire bladder wall in 2 cases. Eight cases showed the local thickening or nodular or flat dune-like shape thickening of the bladder wall, the size of the lesions were 1.0cm × 0.8cm ~ 4.3cm × 5.9cm, two cases showed the diffuse thickening of the bladder wall. Cystal low density were demonstrated in 2 lesions.The bladder exine were smooth in 9 cases.

结果 10例CG中CT表现为膀胱颈部和三角区7例，右前壁1例，累及整个膀胱壁2例。8例CT平扫表现为膀胱壁局限性增厚或呈结节状、扁丘状突向膀胱腔内的软组织密度影，大小1.0cm×0.8cm～4.3cm×5.9cm，2例膀胱壁弥漫性增厚，边缘光整。2例病灶内可见囊性低密度区。9例膀胱外壁光滑。
