In current review we represented new possibilities of intraoperative sonography introduced into clinical practice for the last 20 years. Contrast‑enhanced ultrasound and blood flow imaging (BFI) method are intended for assessment of cerebral hemodynamics. Elastosonography distinguishes tissues by differences of their density. Fusion of sonography with navigation is forwarded to brainshift reduction. Combination of ultrasound with endoscopy is effective in resection of intraventricular tumors and pituitary adenomas. Embedded three‑dimensional sonography is intended to facilitate interpretation of ultrasound results and tailoring craniotomy.

Objective. To study the clinical diagnostic value of contrast-enhanced ultrasound (CEUS) in bladder occupied lesions. Methods. 38 cases of conventional-ultrasound-found bladder occupied lesions did color Doppler flow imaging (CDFI) and CEUS checks. By comparing the difference between two types of blood flow imaging technologies in displaying the flow of bladder occupied lesions and observing the perfusion modes of contrast agents to enter lesions, the perfusion characteristics of CEUS were analyzed. Finally, they were contrasted with the surgical pathology results. Results. Of all the 38 cases, there were 51 bladder occupied lesions, including 43 bladder malignant tumors, 2 bladder inverted papillomas, and 6 glandular cystitis lesions. The blood flow display rate of bladder occupied lesions was 100% using CEUS. Apparently, it was higher than that of CDFI (62.7%), and the result of these showed a statistically significant difference ( P < 0.05 ). Using CEUS, 46 malignant lesions and 5 glandular cystitis lesions were indicated, and the diagnostic accuracy rate was 86.3%. Conclusion. CEUS can improve the blood flow display rate of bladder occupied lesions, and it can also observe the real-time blood flow of these lesions. It can help judge their nature and has a higher clinical value in differentiating the benign from the malignant.
