Intraoperative Ultrasonography For Real Time Imaging During Surgery

Intraoperative ultrasound imaging technique was established in the 1960s.This technique is used during surgery. Initially for the first two decades, this imaging technique did not attract much attention because the available equipment was difficult to use.

However, in early 1980s, with modification in machinery, intraoperative ultrasound became a useful diagnostic technique particularly in neurosurgical procedures. There are several techniques of intraoperative image guidance like open-angioMR, intraoperative angiography or computer assisted neuronavigation that provides better knowledge about the brain vascularisation in the operation theatre to the neurosurgeon.

Intraoperative ultrasound imaging technique spread to a variety of surgical fields, such as hepatobiliary pancreatic surgery, neurosurgery, and cardiovascular surgery.  Hepatic surgery got a new dimension as Intraoperative ultrasound was the only modality that was capable of delineating and examining the interior of the liver during surgery.

Nowadays, this procedure is used widely and the surgeons appreciate the benefits of intraoperative ultrasound. This is an indispensable operative procedure for intraoperative decision-making and guidance of surgical procedures.

This imaging technique is used for real-time depiction and evaluation of relevant anatomy and pathology. The information collected by this technique is crucial to the surgeon and helps to decide the nature and extent of the surgical procedure.

Intraoperative ultrasound using Power Doppler modality is a new technique that is less expensive but produces images that are comparable to conventional angiography images.

During operation, the intraoperative ultrasound imaging is used for making decisions during the course of the operation. Based on the latest and the accurate information available, the surgeon can complete the surgery in the best possible way.
