It’s natural to be really excited by the prospect of your first scan. But some mums find the standard 2D scans disappointing when all they see is a grey, blurry outline. This is because the scan sees right through your baby, so the photos show her internal organs. With 3D and 4D scans, you see your baby’s skin rather than her insides. You may see the shape of your baby’s mouth and nose, or be able to spot her yawning or sticking her tongue out.
3D and 4D scans may nonetheless provide more information about a known abnormality. Because these scans can show more detail. 3D scanning can also be useful to look at the heart and other internal organs. The images generated by 4D Ultrasounds are at par with CT scan images in clarity and detail without any radiation!
Ultrasound waves are able to pass through body tissues to a variable degree. In the case of some body tissues they may pass through unhindered, while in other cases these waves may be partly reflected back, or absorbed by the tissue such as air cells, or be blocked completely as by bone. Those ultrasound waves that get reflected back are received by a transducer. Depending upon the signal strength of the returned waves and the time taken for the return path images can be created which show the broad outline of the organs and some of the structures in them.
Fortunately the transducer that generates the ultrasound waves can also be used to detect these waves on their return path.
Repeat examinations are useful in tracking progress of disease.
Ultrsonography (USG) is a non-invasive procedure which, in most instances, does not require even an injection. Anaesthesia is not required. Patients are advised to wear loose fitting clothes especially since they will be required to expose the concerned area of the body for examination.
The computer program also provides internal calipers for measurements of various dimensions.
Ultrsonography (USG) is useful for measuring the size of various organs under examination , the presence or absence of stone disease or fluid around the organ.
Selected images may be recorded on paper or, on any digital medium either as a video or in single frames. The test usually takes up to a half hour.
No pain is caused. No injections are given.
Please remember that similar results in different clinical circumstances may have different significance. Therefore, it is in your own interests that the reports be shown to your own doctor who recommended the procedure in the first place for the most useful interpretation of data. It is for this reason that our staff are under instructions to encourage you to seek proper interpretation of our reports from your own doctor.
The procedure is a very useful, simple and inexpensive test that helps the doctor to take a “peep” inside the heart. Changes in structure and function of various elements in the heart can be detected with a fair degree of accuracy.
Further, it is useful for assessing progress of disease and adequacy of treatment being taken.
Whereas in many forms of heart diseases it is an invaluable tool for diagnosis and management, it has only a limited use in the diagnosis of coronary artery disease.
