[The clinical value of intraoperative ultrasound of the liver]
1Department of Diagnostic Radiology, Cancer Institute (Hospital), Chinese Academy of Medical Sciences, Peking Union Medical College, Beijing.
Objective:
To evaluate usefulness of intraoperative ultrasound of the liver.
Methods:
A 5.0 MHz ultrasound transducer was used to detect liver lesions, their number, location and relation to the intrahepatic blood vessels.
Results:
Forty two patients with primary liver tumors received intraoperative ultrasonographic examination. Liver tumor was resected in 29 patients(69.0%). The tumors in 4 patients were unresectable due to their close relationship to the hepatic vasculature as judged by the ultrasound image. Multiple lesions were found in 6 patients during operation.
Conclusions:
Intraoperative ultrasound of the liver is sensitive enough to detect most liver lesions and to locate them by liver segment which makes radical tumor resection possible. It is useful to define the tumor in relation to hepatic vasculature. It can compensate for missing lesions in preoperative imaging studies. Fenestration operation for liver abscess and intervention treatment for liver cysts can be performed during operation.

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...
