New US device versus imaging US to assess tumor-in-brain

Area of Science:

• Neurosurgery
• Medical Imaging
• Surgical Technology

Background:

• Traditional ultrasonic imaging systems in surgery are time-consuming and subjective.
• A novel ultrasonic device has been developed to address these limitations.
• This new device has shown promise in brain tumor surgeries.

Purpose of the Study:

• To compare the performance of a new ultrasonic device against conventional systems.
• To evaluate the accuracy and objectivity of the new ultrasonic device.
• To demonstrate the practical applications of the new device in neurosurgery.

Main Methods:

• Ex vivo experiments using porcine muscle and brain tissue to measure thickness and border depth.
• In vivo comparison of tumor depth measurements between the new and conventional ultrasonic devices during human neurosurgeries.
• Real-time monitoring of tumor thickness during resection using the new ultrasonic device.

Main Results:

• High correlation was observed in thickness and border depth measurements between the two devices.
• Tumor depths were monitored with 87% similarity during neurosurgeries, supported by a Pearson's correlation coefficient of 0.44.
• The new device facilitates real-time, remote intraoperative monitoring, improving tumor border visualization.

Conclusions:

• The new ultrasonic device demonstrates superior accuracy and objectivity over conventional ultrasonic imaging systems.
• It allows for precise control of residual tumor thickness during resection, particularly in confined surgical spaces.
• The device is highly beneficial for tumor-in-brain surgeries, especially during the critical final stages of resection.
