After a short description of the physical principles of ultrasound, the indications and usefulness of the real time B-scan technique in the non-invasive diagnosis of cardiac and abdominal diseases are discussed. A correct diagnosis was made in 90% of the cardiac cases (valve abnormalities, pericardial effusion, cardiac aneurysm, cardiomyopathy), whereas the diagnosis by ultrasound was correct in only 81.1% of the abdominal cases (diffuse and localized liver diseases, pancreatitis, pancreatic cyst, carcinoma of the pancreas, cholelithiasis, renal cyst, renal tumours, aortic aneurysm). The advantages of the real time B-scan technique lie in the two-dimenstional clear representation of intracardiac and intraabdominal structures with the possibility of undertaking quantitative measurements. Furthermore, it is a non-invasive and safe method, which can be repeated as often as necessary and can complete the diagnositic spectrum of radiology, endoscopy and nuclear medicine.
在简要描述超声的物理原理之后，讨论了实时B超扫描技术在心脏和腹部疾病无创诊断中的适应证及实用性。在90%的心脏病例（瓣膜异常、心包积液、心脏动脉瘤、心肌病）中做出了正确诊断，而超声诊断在腹部病例中仅81.1%正确（弥漫性和局限性肝脏疾病、胰腺炎、胰腺囊肿、胰腺癌、胆结石、肾囊肿、肾肿瘤、主动脉瘤）。实时B超扫描技术的优点在于能清晰二维显示心内和腹内结构，并有可能进行定量测量。此外，它是一种无创且安全的方法，可以根据需要多次重复，并且能够完善放射学、内镜检查和核医学的诊断范围。
