Ascites: comparison of plain film radiographs with ultrasonograms
Abstract:
Plain film abdominal radiographs of 100 cases of ultrasound-proved ascites were reviewed for findings of ascites. In addition, 100 nonascitic cases proved by sonography were reviewed to evaluate the specificity of these findings. We found that all the described plain film radiographic signs of ascites except the hepatic angle sign are insensitive though specific. The hepatic angle sign has a sensitivity of 84% and a specificity of 70%.

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...
