目的探讨实时超声显像在纵隔子宫妊娠的临床应用价值。方法对42例超声诊断的纵隔子宫妊娠和20例需人工流产患者在超声监视指导下人工流产术进行回顾性分析总结。结果42例患者,超声全部明确诊断,其中20例需要人工流产患者在超声监视下均一次成功,无子宫穿孔、绒毛残留、大出血等并发症。结论超声诊断纵隔子宫妊娠及其在超声监视下人工流产有重要的应用价值。 相似文献

Clinical use of ultrasound imaging by physiotherapists is increasing; however, the clinical setting may be problematic due to variability inherent in the environment. As transducer motion interferes with accurate measurement, this study aimed to measure handheld transducer motion, relative to the pelvis, during a clinical simulation involving typical maneuvers employed in a physiotherapy assessment of the lumbopelvic region. Transducer motion about three axes and through one plane was measured (Vicon, Oxford, UK) on 12 participants during three clinical maneuvers at four abdominal imaging sites. Data were grouped and means used to determine discrepancies in transducer and pelvic motion for each imaging site/maneuver combination. None of the conditions produced large transducer motions relative to the pelvis and all findings were within previously established guidelines for acceptable amounts of transducer motion. These findings suggest that an ultrasound transducer can be held relatively stationary in a clinical setting, for the maneuvers tested. (E-mail: j.l.whittaker@soton.ac.uk) 相似文献

This paper describes a modeling method of the tissue temperature evolution over time in hyper or hypothermia. The tissue temperature evolution over time is classically described by Pennes’ bioheat transfer equation which is generally solved by a finite difference method. In this paper we will present a method where the bioheat transfer equation can be algebraically solved after a Fourier transformation over the space coordinates. As an example, we implemented this method for the simulation of a percutaneous high intensity ultrasound hepatocellular carcinoma curative treatment and compared it with the finite difference method and experimental data. 相似文献

Endoscopic ultrasound‐guided fine‐needle aspiration (EUS‐FNA) is a useful modality when the target is a lymph node located in the mediastinum, perigastric area or perirectum. Although it is difficult to carry out EUS‐FNA of the colon using an oblique view linear scope, we report two cases of successful EUS‐FNA of the lesions via the proximal sigmoid colon using a recently available new convex type EUS scope. Case 1 was a 77‐year‐old Japanese woman noted to have multiple lymph node swelling in the para‐aortic area and in the pelvis. Case 2 was a 60‐year‐old Japanese woman noted to have a large mass in the left lower abdomen. In case 1, oral EUS showed no lymph node swelling. In both cases, EUS with forward‐viewing radial echoendoscope was carried out via the anus, and multiple lymph‐node swelling or a large mass was observed near the proximal sigmoid colon. In the EUS‐FNA for these cases, we used a new convex‐type EUS scope that has an oblique view, but with a wide‐angled optical device giving a view similar to a forward one. EUS‐FNA was successfully carried out on the lesions. The pathological specimen revealed diffuse large B‐cell lymphoma in case 1 and gastrointestinal stromal tumor (GIST) in case 2. 相似文献
