Ultrasound: A Safe Imaging Technique in Radiology
Ultrasound is a widely used imaging technique in radiology that utilizes high-frequency sound waves to generate detailed images of the body. Unlike other imaging methods, ultrasound is considered completely safe as it does not involve any radiation exposure. During an ultrasound examination, a radiology technologist applies a water-based gel on the skin to enhance the transmission of sound waves. Then, a transducer is gently maneuvered over the specific area of interest to capture the image.
What is a CT Scan?
A CT scan, also known as a computed tomography scan, is a medical imaging procedure that utilizes x-rays to produce detailed cross-sectional images of various parts of the body. This non-invasive technique can capture images of the head, back, abdomen, chest, and other areas of interest. With its high-speed scanning capabilities, CT scans provide quick and accurate images for medical evaluation, with some scans taking as short as 30 seconds to complete.
