Knowledge Point

Three-dimensional ultrasound: Based on the principle of two-dimensional imaging, background software is used to convert the image into a three-dimensional image. That is to use backend software to create three-dimensional images from many floor plans. It can clearly display the three-dimensional form, surface characteristics, and spatial position relationships of suspicious structures, and provide three-dimensional images of areas of interest.

Four-dimensional ultrasound: it is dynamic three-dimensional. Four-dimensional ultrasound technology uses three-dimensional ultrasound images plus time dimension parameters. This revolutionary technology can obtain three-dimensional images in real time, surpassing the limitations of traditional ultrasound. Ability to display real-time dynamic moving images of areas of interest.

Why do some ultrasound examinations require holding back urine? How much is appropriate to hold in?​

Before conducting urinary system examinations such as bladder, ureter, and prostate, as well as gynecological ultrasound examinations in unmarried women, patients with heavy vaginal bleeding, and patients in the first three months of pregnancy, it is necessary to hold back urine and fill the bladder appropriately to reduce intestinal gas interference and provide good Acoustic window. For gynecological ultrasound, the bladder urine volume is required to be 300-400ml. As far as experience is concerned, drinking 500-800ml of water before the examination generally requires holding in urine for 2 hours, and drinking 800-1000ml of water requires holding in urine for about 1 hour. A good sign of a full bladder is that the lower abdomen bulges in a shallow arc when lying down, and can be pressed down and held back when pressure is applied.
