Image quality of real time 4D-US was significantly superior to both, conventional 2D-US and also to 2D-CEUS.The authors concluded that the assessment of bladder cancer using real time 4D-US is feasible and improves the image quality and therefore also the precise anatomical consistency of intravesical tumor masses.Article 279: the EPIQ System and other Philips and no-Philips ultrasound systems were used successfully for the diagnosis of persistent sciatic artery (PSA) compared to computed tomography angiography (CTA), which is the established standard for diagnosis of PSA.
