罗库溴铵与琥珀胆碱对脑血管血流动力学的影响及比较

研究罗库溴铵与琥珀胆碱对脑血管血流动力学的影响，以进一步证明作为全麻诱导用药，前者取代后者的合理性。方法：４６例择期病人随机分成两组，罗库溴铵组（Ｒ组）２１例，琥珀胆碱组（Ｓ组）２５例。全麻诱导应用芬太尼和硫喷妥钠后，Ｒ组静注罗库溴铵０．９ｍｇ／ｋｇ，Ｓ组静注琥珀胆碱１．５ｍｇ／ｋｇ。分别于全麻诱导前后，静注肌松药后１、５、１０分钟时检测ＣＶＤＩ。结果：（１）两组全麻醉诱导后平均，最小脑血流量（Ｑ     

Clinically and mammographically occult invasive ductal carcinoma diagnosed by ultrasound: The focally dilated duct

A case of clinically and mammographically occult invasive ductal carcinoma presenting as a focally dilated duct on ultrasound is reported. The features of ductal dilatation in benign and malignant conditions on ultrasound are highlighted.     

Efficient pulse sequence for multisection dual-repetition time MR image acquisition

A magnetic resonance imaging pulse sequence was developed in which multisection spin-echo image data are simultaneously acquired for two repetition time (TR) intervals (TR1 and TR2) in one imaging sequence. In a conventional multisection image at a single TR, the number of sections is limited to TR/TS, where TS is the readout time. With this new sequence, the number of sections that can be imaged at both TRs in one acquisition is equal to (TR1 + TR2)/(TS1 + TS2), where TS1 and TS2 may be different for the two TRs. Imaging time is equal to that for a single image at a TR of TR1 + TR2. Clinical images were obtained with the new sequence from 15 patients and compared with images acquired at the same TR/TE by means of standard multisection single-TR methods. Relative image quality was assessed by three radiologists in 37 comparisons. In general, the dual-TR results at the long TR were judged equivalent to those from a single-TR image. Dual-TR results at the short TR had a modest reduction in contrast, but in none of 15 cases were any pathologic features missed.
