    [摘要] 医学影像学目前已从传统的解剖成像进入了功能和分子显像时代，使影像诊断准确率大幅升高。现今，X线、CT、MRI技术已常规应用于疾病的诊断、治疗指导及治疗效果评价，医学影像图像实现了从二维到三维成像，甚至是四维成像的功能成像转变。各项技术各有其优缺点及适用情况。超声分子显像技术是一种潜在的、较为理想的分子显影方法，是今后该领域研究的热点。

    [Abstract] Medical imaging has from the traditional anatomical imaging into the function and molecular imaging era. Imaging diagnostic accuracy has sharply rising. Nowadays， X-rays， CT， MRI have routinely applied in the diagnosis of the disease， guiding treatment and treatment effectiveness evaluation. Medical imaging image achieves changes from 2 D to 3 D imaging， and even the 4D imaging. In clinic， all the techniques have their advantages and disadvantages and applicable condition. Ultrasonic molecular imaging technology has became a kind of potential and ideal molecular imaging method ......
