Echogenicity (sometimes as echogenecity) or echogeneity is the ability to bounce an echo, e.g. return the signal in medical ultrasound examinations. In other words, echogenicity is higher when the surface bouncing the sound echo reflects increased sound waves.
This allows for the detection of a pneumothorax with the absence of normal ‘lung-sliding’ and ‘comet-tail’ artifact (seen on the ultrasound screen). Compared with supine chest radiography , with CT or clinical course as the gold standard, bedside sonography has superior sensitivity (49–99% versus 27–75%), similar specificity (95 ...
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
Story at a glance Screening for cancer can take a long time, depending on the necessary tests. Biopsies may be necessary for diagnosis, such as for lung cancer. Robotic-assisted bronchoscopy is a ...
The location of the thrombus and its detail will inform of the seriousness of the condition. In a deep vein thrombosis (DVT), or in a superficial vein thrombosis where the thrombus is floating, an emergency situation will be indicated. If the thrombus is near to the sapheno-femoral junction there will be a high risk of a pulmonary embolism ...
These procedures generally use lower frequencies than medical diagnostic ultrasound (from 0.7 to 2 MHz), but higher the frequency means lower the focusing energy. HIFU treatment is often guided by MRI. Focused ultrasound may be used to dissolve kidney stones by lithotripsy. Ultrasound may be used for cataract treatment by phacoemulsification.
In April 2013, the Journal of the American College of Cardiology published a study that relied on Life Line Screening data from a population-based screening study of more than 3.6 million Americans. Results showed the prevalence of peripheral artery disease (PAD) increased from 1 in 50 in the 40-to-50-year-old age group, to nearly 1 in 3 in the ...
The first location of the hospital in Columbus. Children's Hospital of Columbus opened in 1892 with 9 patient beds, which quickly grew to 15 beds. In 1922, the cornerstone for the new hospital was laid, and in 1924, the new hospital opened accommodating 75 patients with the ability to expand to 150 beds immediately (eventually going to 300 beds ...
