  flair imaging
     Results:The experimental in vitro study showed that increased signal intensity was shown in case that the protein concentration in the fluid was increased(>1.64g/dl) and a tendency of gradual increase in signal intensity was also demonstrated in case of increasing the delay of TI. The differentiation between hepatic cyst and hemangioma could be made possible by FLAIR imaging with an optimal TI value(TI 1700ms,P<0.05).
     结果:体外实验结果显示FLAIR成像随液体蛋白浓度(≥1.64 g/dl)升高和TI值延长其信号呈逐渐升高趋势,优选参数FLAIR成像(TI 1700 ms)可鉴别肝囊肿与肝血管瘤(P<0.05)。

  flair imaging
Fluid-attenuated inversion recovery (FLAIR) imaging with prolonged inversion times allows generation of highly T2-weighted images of the brain with suppression of cerebrospinal fluid signal.
      
FLAIR imaging allowed identification of 45 % more high-signal lesions than T2-weighted or PD images in the 10 patients.
      
The aim of our study was to determine whether fluid-attenuated inversion recovery (FLAIR) imaging and diffusion-weighted imaging (DWI) would be helpful in characterizing primitive neuroectodermal tumors (PNET) from other pediatric brain tumors.
      
The differences in the histologic architecture between PNET and non-PNET are reflected in both FLAIR imaging and in DWI.

Objective: To evaluate fast FLAIR pulse sequence in abdominal and pelvic applications.Materials and Methods:Thirty eight patients with fluid containing lesions in abdomen or pelvic cavity were imaged with fast FLAIR pulse sequence after routine T 1WI and T 2WI, using the following parameters: TR=5 000~6 000ms, TI=1 500~2 000ms, TE=90~120ms.Results:Of 38 patients, 27 underwent surgical treatment. The lesions were proved to be as the following diseases: huge hepatic cyst (n=7), hepatic abscess (n=3), subdiaphragmatic...

Objective: To evaluate fast FLAIR pulse sequence in abdominal and pelvic applications.Materials and Methods:Thirty eight patients with fluid containing lesions in abdomen or pelvic cavity were imaged with fast FLAIR pulse sequence after routine T 1WI and T 2WI, using the following parameters: TR=5 000~6 000ms, TI=1 500~2 000ms, TE=90~120ms.Results:Of 38 patients, 27 underwent surgical treatment. The lesions were proved to be as the following diseases: huge hepatic cyst (n=7), hepatic abscess (n=3), subdiaphragmatic abscess (n=2), old hemorrhagic cyst of pancreatic head (n=1), large renal cyst (n=3), nephrohydrosis (n=2), huge ovarian simple cyst (n=5), cystadenocarcinoma of ovary (n=1), parovarian cyst (n=1), early embryo (n=1) and malignant mole (n=1). On FLAIR images, hepatic and subdiaphragmatic abscess, old hemorrhage of pancreatic head and malignant mole presented as hyperintensity lesion, while nephrohydrosis, ovarian simple cyst and early embryo had a signal intensity as low as that of CSF or urine. Renal cyst and ovarian cystadenocarcinoma were isointensity. Signal of hepatic cysts varied from low intensity to slightly hyperintensity.Conclusion: Fast FLAIR pulse sequence is helpful in making differential diagnosis of fluid containing lesion in abdominal or pelvic cavity.

Objective To study the role of turbo fluid attenuated inversion recovery (FLAIR) pulse sequence MR imaging in diagnosing subacute and chronic subarachnoid hemorrhage (SAH). Methods The turbo FLAIR images of 30 healthy brains and 17 patients with SAH 4-35 days after the ictus were obtained at T5NT 0.5 T superconductivity MR scanner. The findings of subacute and chronic SAH on FLAIR images were compared with the findings on conventional spinecho MRI and CT images, then, a blind study of the fortysix FLAIR images was performed to verify the reliability of the comparative evaluation. Results The visualization of SAH on CT and MRI depended partly on the time after the ictus. In visualization of subacute and chronic SAH, FLAIR(94% detection) was significantly superior to T1WI(41%, P<0.01) and CT(27%, P<0.01). FLAIR detected all the subacute SAH(100%), whereas T1WI and CT detected 42%(P<0.01) and 33%(P<0.01), respectively. In a blind comparative study, no falsepositive or falsenegative identification was made. Conclusions Turbo FLAIR MR imaging is a reliable technology to visualize and confirm the subacute and chronic SAH, it is superior to conventional MRI or CT and should be used as a routine method in diagnosing the disease.

目的研究MR快速液体衰减反转恢复(fluidatenuatedinversionrecovery,FLAIR)序列诊断亚急性和慢性蛛网膜下腔出血(subarachnoidhemorhage,SAH)的价值。方法30例头部健康者和17例次SAH患者在发病后第4~35天进行头部MRI检查。扫描机为0.5T超导MR机。观察亚急性和慢性SAH在FLAIR的信号表现,并与同期CT和常规MRI所见比较。再对46个正常和病变的FLAIR图像做双盲比较分析,以评价其诊断可靠性。结果FLAIR成像显示亚急性和慢性SAH(94%)明显优于T1WI(41%,P<0.01)和CT(27%,P<0.01)。尤其在亚急性期,FLAIR成像显示率达100%,与CT(33%,P<0.01)相比差异有非常显著性意义。双盲分析结果,无一例假阳性和假阴性诊断。结论快速FLAIR序列诊断亚急性和慢性SAH明显优于CT和常规MRI,应作为本病检查的常规方法

126 patients with intracranial tumors were examined with fast fluid-attenuated inversion-recovery (FLAIR) and routine MR imaging including fast spin-echo T2WI and T2WI simultaneously. The value of FLAIR in the diagnosis of intracranial tumors were investigated by comparising with SE T2WI. The contrast between lesions and the background was revealed better on the FLAIR images than that on T2WI. So did the detectabilities of the location, size, contour, extent and numbers of the lesions. We concluded that fast FLAIR pulse sequence should be listed on the routine MR imaging as a complementing modality of FSE T2WI.

126例颅脑肿瘤同时行快速液体反转回复序列(Fast FLAIR)成像和常规FSET_2W成像。通过比较分析两者显示病变的能力,探讨FLIAR对颅脑肿瘤的诊断价值。结果显示FLAIR序列MRI较T_2WI有更高的对比度,在显示病变的部位、大小、轮廓、范围和数目方面具有更好的敏感性。作者认为,快速FLAIR序列可作为常规SE T_2WI的必要补充,建议列为颅脑肿瘤MRI检查的常规扫描。
