General ultrasound is a basic procedure for routine examinations for the purpose of periodic health checks of all organs in the body or evaluation of known diseases. Ultrasound is a safe, non-invasive imaging method and is often indicated in the examination and diagnosis of many different diseases.
1. What is ultrasound?
Ultrasound is an imaging method that uses sound waves with frequencies higher than 20,000 Hz. Accordingly, ultrasound imaging uses sound waves to create images of the inside of the body.
2D ultrasound is the default mode, which is started when any ultrasound / ultrasound machine is turned on. It is a 2-D cross-sectional view of the underlying structures and is made up of multiple B-mode (grayscale mode) scan lines. This is the most intuitive of all modes to understand. Field of view is the portion of organs or tissues that are intersected by the scan plane. Depending on the transducer used, the shape of this field can be either an area - commonly seen with Echo and abdominal ultrasound probes or a rectangular or trapezoidal shape seen with superficial or vascular probes.

Most ultrasound is non-invasive (no needles or injections) so there are no harm or side effects. Performing an ultrasound may be temporarily uncomfortable, but not painful. Ultrasound is widely available, easy to use, and less expensive than most other imaging methods. Ultrasound imaging is extremely safe and does not use radiation. Ultrasound gives clear images of soft tissues that are not clearly visible on radiographs. Ultrasound is the preferred imaging modality for the diagnosis and monitoring of pregnant women and their fetuses. Ultrasound provides real-time images, making it a good tool to guide minimally invasive procedures such as needle biopsies and fluid aspiration. In terms of risk, standard diagnostic ultrasound has no harmful effects on humans.
It can be said that general ultrasound is just a simple, fast, harmless routine probing technique that can help doctors detect abnormal signs in some organs in the body to that can be promptly treated.
