Purpose:
The aim of this study was to assess the agreement between intraoperative transcranial sonography (TCS) and postoperative computed tomography (CT) in patients with traumatic brain injuries.
Methods:
We performed a retrospective cross-sectional study of 35 patients who underwent TCS during surgery, among those who presented to a regional trauma center and underwent decompressive craniectomy between January 1, 2017 and April 30, 2020.
Results:
The mean difference between TCS and CT in measuring the midline shift was -1.33 mm (95% confidence interval, -2.00 to -0.65; intraclass correlation coefficient [ICC], 0.96; P<0.001). An excellent correlation was found between TCS and CT in assessing contralateral subdural hematomas (ICC, 0.96; P<0.001) and focal hematoma lesions (ICC, 0.99; P<0.001). A very good correlation between TCS and CT was found for measurements of ventricle width (ICC, 0.92; P<0.001).
Conclusions:
TCS during surgery is considered an effective diagnostic tool for the detection of intraoperative parenchymal changes in patients with traumatic brain injuries.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
