Place of ultrasound and radiography in obstetrics
Abstract:
In the two years after an ultrasound service was introduced at this hospital obstetric referrals for abdominal radiography decreased by over 55%. Most of these were for estimation of fetal maturity. Out of 349 such patients subjected to radiography in 1976, 176 had already been examined by ultrasound; in only four did radiography appear to influence management. We believe that if a satisfactory ultrasound scan is obtained before 30 weeks of gestation subsequent radiological estimation of fetal maturity is unjustified. Radiography may still be necessary, however, for diagnosing fetal abnormalities.

Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
