摘要： Ultrasound contrast agents comprising microbubbles of biocompatible gas, e.g. a sulphur halide or a perfluorocarbon, stabilized by opsonisable amphiphilic material, e.g. a membrane-forming lipid such as a phospholipid, especially a negatively charged phospholipid such as a phosphatidylserine, may exhibit prolonged contrast-generating residence time in the liver following intravenous administration.

摘要： Ultrasound imaging using gas microbubble-containing contrast agents may be performed in the recirculating phase following admixture of the contrast agent with the blood pool, thereby prolonging the useful imaging time window compared to that conventionally obtained during the backscatter signal peak resulting from first pass of a contrast agent bolus. The length of the time window may further be increased by imaging at ultrasound frequencies of 2 MHz or less, particularly by harmonic imaging at transmit frequencies less than the resonance frequencies of the gas microbubbles.
摘要翻译：使用气体微泡造影剂的超声成像可以在造影剂与血液池混合之后的再循环阶段中进行，从而延长了有用的成像时间窗口，与之前获得的反向散射信号峰值相比，造影剂推注。特别是通过低于气体微泡的共振频率的发射频率下的谐波成像，可以进一步通过在2MHz或更小的超声频率下成像来增加时间窗口的长度。

摘要： Ultrasonic visualization of a subject, particularly of perfusion in the myocardium and other tissues, is performed using novel gas-containing contrast agent preparations which promote controllable and temporary growth of the gas phase in vivo following administration and can therefore act as deposited perfusion tracers. The preparations include a coadministerable composition comprising a diffusible component capable of inward diffusion into the dispersed gas phase to promote temporary growth thereof. In cardiac perfusion imaging the preparations may advantageously be coadministered with vasodilator drugs such as adenosine in order to enhance the differences in return signal intensity from normal and hypoperfused myocardial tissue respectively.
摘要翻译：使用新型含气体的造影剂制剂，使用受试者的超声波可视化，特别是心肌和其他组织中的灌注进行，其在给药后在体内促进气相的可控和临时生长，因此可用作沉积的灌注示踪剂。制剂包括可共混组合物，其包含能够向内扩散到分散气相中以促进其暂时生长的可扩散组分。在心脏灌注成像中，制剂可以有利地与血管扩张剂药物如腺苷共同施用，以分别增强来自正常和低灌注心肌组织的返回信号强度的差异。

摘要： A combined preparation comprising: i) an ultrasound contrast agent capable of accumulation in tissue microvasculature; and ii) a pharamacologically effective amount of a vasodilator drug may be used in perfusion imaging, especially of the myocardium. The contrast agent accumulates in tissue in concentrations related to the regional rate of tissue perfusion, and the vasodilator drug enhances distinction between normally perfused and underperfused tissue.

摘要： The present invention relates to a method of processing ultrasound images from a subject preadministered with an ultrasound contrast agent wherein quantitative measures of the contrast enhancement pattern of said lymph nodes are generated. The lymphatic system is made of vessels or ducts that begin in tissues and are designed to carry lymph fluid to local lymph nodes where the fluid is filtered and processed and sent to the next lymph node down the line until the fluid reaches the thoracic duct where it enters the blood stream. Lymph fluid which enters the lymph vessels carries with it substances and materials from the tissue, e.g. antigens, particles and cells. The lymph nodes process the lymph fluid by sieving it and macrophages inside the nodes remove particulate and cell material carried by the lymph fluid via phagocytosis.

摘要： Radioactive sources, preferably radioactive seeds, for use in brachytherapy comprising a radioisotope within a sealed biocompatible container, wherein at least one part of the outer surface of the container is grooved, preferably with a curved groove. The grooved outer surface is preferably substantially free from angularities. Such grooves enhance the echogenicity of the source using medical ultrasound at a greater range of angles to the ultrasound probe, thus enhancing the ultrasound visibility of the source. Preferred radioisotopes are palladium-103 and iodine-125.
