Sonographic Murphy sign
Sonographic Murphy Sign
The Sonographic Murphy Sign (pronounced: soh-noh-graf-ik mur-fee sign) is a medical term used in the field of Radiology and Gastroenterology. It is a diagnostic tool used to detect Acute Cholecystitis, a condition characterized by inflammation of the gallbladder.
Etymology
The term is named after the American surgeon John Benjamin Murphy, who first described the clinical sign. The prefix 'Sonographic' is derived from the word 'Sonography', a type of medical imaging technique that uses high-frequency sound waves to produce images of organs within the body.
Definition
The Sonographic Murphy Sign is defined as the presence of maximal tenderness elicited by the pressure of the ultrasound probe over the visualized gallbladder. It is a highly specific sign for Acute Cholecystitis.
Procedure
The procedure for detecting the Sonographic Murphy Sign involves the use of an Ultrasound machine. The patient is asked to fast for several hours before the test to ensure that the gallbladder is distended. The ultrasound probe is then placed over the area of the gallbladder, and the patient is asked to take a deep breath. If the patient experiences pain or stops inhaling when the ultrasound probe is over the gallbladder, it is considered a positive Sonographic Murphy Sign.
