Object. Three-dimensional (3D) power Doppler ultrasonography imaging provides a rapid, noninvasive visualization of ruptured intracranial aneurysms, including their relationship to other vascular structures. Methods. The authors used transcranial 3D power Doppler imaging in the emergency room to examine patients with acute subarachnoid hemorrhage. In all patients, the ruptured aneurysm was rapidly located with 3D power Doppler imaging. Conventional x-ray angiography confirmed both the ultrasonography-based diagnosis and the location of aneurysmal bleeding. Conclusions. These preliminary results indicate that 3D power Doppler imaging is a rapid, noninvasive screening method for the visualization of ruptured aneurysms.

3D Ultrasonography

Purpose. The aim of this study was to determine the value of 3D and 3D Power Doppler sonography in the detection of tumor malignancy in breast lesions and to find new diagnostic criteria for differential diagnosis.Methods. One hundred and twenty five women with clinically or mammographically suspicious findings were referred for 3D Power Doppler ultrasound prior to surgery. Histological diagnosis was conducted after surgery and compared with ultrasound findings. Sonographic criteria used for breast cancer diagnosis were based on a system that included morphological characteristics and criteria of the vascular pattern of a breast mass by Power Doppler imaging.Results. Seventy-two lesions were histopathologically diagnosed as benign and 53 tumors as malignant. Three-dimensional ultrasound identified 49 out of 53 histologically confirmed breast cancers resulting in a sensitivity of 92.4% and a specificity of 86.1% in diagnosing breast malignancy (PPV: 0.83, NPV:0.94).Conclusions. 3D ultrasonography is a valuable tool in identifying preoperatively the possibility of a tumor to be malignant.

ABSTRACT Background The assessment of the endometrial receptivity at the time of human chorionic gonadotrophin (hCG) is one of the key factors for success of all ART procedures. Aim To assess, if 3D and 3D power Doppler assessment of endometrial receptivity before giving hCG, helps improving pregnancy rates in superovulation with IUI cycles. Settings and Design A prospective randomized study of 2500 cycles of IUI was done over a period of twelve months for pre-hCG endometrial assessment. Method Endometrial assessment was done on Voluson 730 Expert, (Wipro GE) using transvaginal multifrequency volume probe 5 to 9 MHz. When follicles and endometrium were considered mature by 2D US and color Doppler, 3D and 3D power Doppler assessment of the endometrium was done before giving hCG. These values were evaluated for conception and nonconception groups. Results Conception rates were higher, when endometrial volume was between 3 and 7 cc. In our study, we have found endometrial FI > 20 and endometrial VFI > 40 as most optimum. Conclusions 3D ultrasound is accurate for volume assessment of endometrium. 3D and 3D PD, when used with 2D US and color Doppler for pre-hCG endometrial assessment, it would definitely improve implantation rates in IUI cycles.
