복부초음파의 이로과 실기 : 간-담도 이외 복부장기

다국어 초록 (Multilingual Abstract)

Ultrasonography (US) is noninvasive and provides anatomical information of the retroperitoneal, intra-abdominal, and pelvic structures. US provides images in real-time and so can also be used to interrogate the movement of structures such as cardiac valves, interactive guidance of biopsies and drainage procedures and, using the Doppler mode, the patterns of blood flow in both large and small vessels. Although US has found major applications in the heart, abdomen and pelvis, as well as in the neck, breast, peripheries and neonatal brain, perhaps its most important clinical impact is in obstetrics. Patients readily accept an US examination because the procedure requires only light pressure on the skin and preparation is minimal: bladder filling is required for pelvic ultrasound and fasting is necessary for the gallbladder, but otherwise the patient may be examined with this technique as and when convenient, a major advantage for emergency uses. In addition, mobile US systems that can be taken to the bedside, to intensive care and into the operating room are widely available.
