About this trial

Objective of the study is to determine possibilities of intraoperative sonography in detecting of various brain mass lesions, assessing extent of their resection and define indications to use ultrasound-guided needle or ultrasound wire-guided port.

Trial outcomes

Primary outcomes

1

Ultrasound features of various brain mass lesions in Mair scale (in grades)

Assessment of target visibility, echogenicity, homogeneity and border demarcation in sonography and their comparison to preoperative computed tomography and magnetic resonance imaging

Time frame
Intraoperatively

Secondary outcomes

1

Sensitivity of intraoperative sonography to detect mass lesion compared to preoperative magnetic resonance imaging or computed tomography (in percents)

Sensitivity = true detection of mass lesion / (true detection of mass lesion + inability to detect mass lesion) x 100

Time frame
Intraoperatively
2

Sensitivity of intraoperative sonography to detect residual mass lesion compared to postoperative magnetic resonance imaging or computed tomography (in percents)

Sensitivity = true detection of residual mass lesion / (true detection of residual mass lesion + inability to detect residual mass lesion) x 100

Time frame
Within 48 hours after surgery
3

Specificity of intraoperative sonography to detect residual mass lesions compared to postoperative magnetic resonance imaging or computed tomography (in percents)

Specificity = true absence of residual mass lesion / (true absence of residual mass lesion + false detection of residual mass lesion) x 100

Time frame
Within 48 hours after surgery
4

Positive predictive value of intraoperative sonography to detect residual mass lesions compared to postoperative magnetic resonance imaging or computed tomography (in percents)

Positive predictive value = true detection of residual mass lesion / (true detection of residual mass lesion + false detection of residual mass lesion) x 100

Time frame
Within 48 hours after surgery
