Ultrasound technology developer Zonare Medical Systems of Mountain View, CA, is showing several new products at this week's European Congress of Radiology (ECR) in Vienna, Austria.
The new general imaging release for the z.one ultra system includes new advanced software applications and transducers designed to enhance image quality and performance across various clinical applications. New capabilities include contrast-enhanced imaging studies, elastography applications, and 3D imaging.
Zonare also is showing as a work-in-progress a new feature for contrast-enhanced ultrasound studies of the liver and heart. Using contrast-enhanced ultrasound with Zonare's new C4-1 curved-array transducer can offer additional diagnostic information in liver lesion assessment by narrowing down the differential diagnosis, similar to contrast-enhanced CT of liver lesions, according to the company.
The company's new C9-4t is a tightly curved, small-footprint, high-frequency transducer designed for pediatric head and abdomen imaging. The field-of-view offers up to 134° of imaging with 2D frequency choices from 9 MHz to 4 MHz for enhanced imaging of neonatal to larger infant body types.
The C4-1 transducer is a small-footprint, curved-array transducer designed to address technically difficult-to-image patients, and offers physicians improved access and imaging performance, resulting in increased penetration (up to 35 cm) with sensitive Doppler imaging.
The z.one ultrasound system now features new elastography applications that enable qualitative visual assessment of the mechanical stiffness properties of tissue. The high-resolution elastography images are generated and visualized using various grayscale and colorized maps, and all linear-array transducers are supported. Clinicians using the new applications report that this technique may provide significant new diagnostic information, according to Zonare.

![Examples of ultrasound findings and techniques. (A) Images in a 39-year-old male patient with a mass in the left thigh. The mass is heterogeneous on the B-mode US image (compared with the patient in D) and showed increased microvascularity (superb microvascular imaging [SMI]) and shear-wave elastography (SWE) values. Undifferentiated pleomorphic sarcoma was diagnosed at biopsy (with pleomorphic rhabdomyosarcoma in surgical specimen). (B) Images in an 18-year-old male patient with a mass in the left leg. The mass is hypoechoic on the B-mode image, with no other findings suggestive of malignancy. The lesion is in contact with the cortex of the tibia, which is slightly irregular. CT revealed a doubtful anteromedial tibial erosion. The microvascular study demonstrated high vascularization, suggestive of malignancy. Periosteal Ewing sarcoma was diagnosed with both histologic and immunohistochemical confirmation. (C) Images in a 69-year-old female patient with a lump growing on the outside of the left leg. Multiple SWE examinations were performed (please note the high values obtained in the measurements, whereas the color map highlights the stiffness relative to adjacent tissues). SMI showed areas of increased vascularization to target for sampling. Undifferentiated spindle cell sarcoma was diagnosed at biopsy, with residual leiomyosarcoma in the surgical specimen after neoadjuvant therapy. (D) Images in a 56-year-old female patient with a mass in the right thigh. The mass is heterogeneous at both B-mode ultrasound (similar to patient A) and MRI (coronal T2-weighted spectral attenuated inversion recovery [SPAIR]; T1-weighted pre-contrast and postcontrast imaging), which even shows uptake after the administration of paramagnetic contrast material, which is traditionally suggestive of malignancy. Low values at SMI and elastography are suggestive of benignity. Spindle cell lipoma was diagnosed at biopsy, with atypical spindle cell lipomatous tumor in the surgical specimen.](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/08/images-radiol250278fig2.APCFLSvX6p.jpg?auto=format%2Ccompress&dpr=2&fit=crop&h=167&q=70&w=250)
