What occurs during Sonography?

Sonography is recognized as a medical examination that uses high-frequency noise waves- also known as ultrasound waves—to recoil off of structures in the body and generate a picture. The examination is also called a sonogram.

The examination uses a device named a transducer made by the sonography machine Manufacturers that is placed on the surface of the patient’s body and directs ultrasound waves and heeds for an echo. A computer interprets the ultrasound waves into a picture. This picture is looked at by a skilled technician who can view, measure and recognize structures. The doctor will then look at the picture and help identify the disease. 

The rationale for the Examination

A sonogram seizes a live picture of what’s happening inside the human body. It works like a camera that takes images of body parts or procedures in real-time. The process helps assess the size, outline, and thickness of tissues to help identify certain medical circumstances. Usually, sonography is prodigious for looking into the stomach without having to cut it open.

A sonogram is most usually used to observe the growth of the uterus and fetus during gravidity. It can also be used to assess glands, breast lumps, joint conditions, bone disease, testicular swellings, or to steer needles during biopsies.

Sonography can also identify blood or fluid movement that transfers toward or away from the transducer. It uses color overlaps on the picture to show the course of the current. Very solid and thick tissues or empty spaces, such as structures filled with gas, do not direct ultrasound waves and therefore cannot be observed on a sonogram produced on equipment made by sonography machine Manufacturers in India.

Doctors often order a sonogram before stirring on to imaging technologies that have more probable problems. Computerized tomography (CT), for instance, exposes you to noteworthy levels of radioactivity.

Safeguards and Hazards

A sonogram is a noninvasive imaging examination that has no known problems. Ultrasound waves are believed to be innocuous. While the energy of the ultrasound waves could aggravate or disturb tissues with protracted exposure, the computer moderates the power of the sound. Also, a trained technician uses methods to minimalize exposure times and approaches, making sonography the most reliable of all imaging examinations.

Before the Test

Healthcare providers command sonography as a first-line examination, usually together with blood examinations. In an emergency location, sonography will characteristically be done right away. For an examination on a future date, find out if you must or must not eat or drink anything before the examination. The response may change contingent on the purpose of the examination.

Time is taken for the examination

A sonogram typically doesn’t take lengthier than 30 minutes. In most instances, it’s vital to arrive about 15 minutes before the examination to fill out forms and perhaps answer other questions. If the examination requires that you imbibe liquids to fill your bladder, you might need to drink water before the examination.

What occurs during the Examination

In many situations, a sonogram is over before you identify it. Here’s what you can imagine:

Through the Examination

A sonogram is directed by a single technician right at the bedside. The technician will ask you to strip enough to reveal the part where the test will be done and to lie down on the bed.

The technician will cover the transducer with conductive cream, which feels like a lubricant. If likely, contingent on the tools and supplies obtainable, the cream will be warm. Then the technician will slither the transducer over the skin, occasionally with firm pressure. Infrequently, the pressure can cause slight uneasiness.

Using the transducer to point to parts of interest, the technician will use the computer to seize pictures and might use a mouse to drag shapes across the screen. The lines help quantify the size, like a virtual index. You would be able to watch the entire process and even ask queries throughout the process.


When the sonogram is over, the technician will typically deliver a towel to wipe off the conductive cream. Once the technician settles that all the essential imageries have been taken, you will be free to get dressed. 

What occurs after the test

Once the technician obtains all the images, they will check with the radiologist (a healthcare provider skilled to read pictures) to make sure no other opinions are required. Medical etiquettes call for the radiologist to understand the pictures from a sonogram before sending a report to the healthcare provider. The provider then discloses the outcomes to the patient.
