Versatile diagnosis and interventional guidance

RADIOLOGY CLEARLY DEFINED

Hitachi provides clinicians with optimal platforms, specialised transducer and innovative technology combinations. With more than 40 compatible transducers and the most advanced image-processing technology, your ultrasound system can become a powerful, highly versatile diagnostic tool. Additional endocavity or interventional transducers and optional features, such as Real-time Virtual Sonography (RVS), Real-time Bi-Plane Imaging (RTBi), Real-time Tissue Elastography (RTE) or Contrast Harmonic Imaging (CHI) - can further elevate your performance.

  • Shear Wave Measurement (SWM)
    SWM incorporates a reliability indicator, VsN, from which the precision and reproducibility of the median shear wave speed measurement can be assessed. Combinational use of SWM and RTE is now achievable with one transducer, to gain a better understanding of the tissue elasticity.
  • Real-time Tissue Elastography (RTE)
    In breast applications, RTE has been shown to improve both the accuracy in differentiating between benign and malignant tumours (especially if smaller than 1cm) and specificity compared with US BIRADS classification, for benign lesions. As a result, elastography can reduce the biopsy rate in atypical cysts and may suggest appropriate workup for cancers with atypical presentation.
    In the prostate, elastography can improve the visualization of cancer. Real-time elastography targeted biopsy has been shown to be significantly more likely to detect prostate cancer than systematic US guided biopsy. Using an endoscopic approach, RTE of the pancreas and lymph nodes has been shown to be capable of further defining the characteristics of benign and malignant lesions and can be used to guide biopsy sampling for diagnosis.
    Within the thyroid gland, RTE provides additional features of malignancy and can be used to guide biopsies of complex lesions.
    Other clinical examination areas for which preliminary studies have shown that Real-time Tissue Elastography can provide additional diagnostic information include musculoskeletal, cervix and testes.
  • Real-time Virtual Sonography (RVS)
    Offering a real-time simultaneous display of the CT or MRI scan plane which corresponds to the ultrasound image, RVS offers superior image guidance for all interventional procedures. It can provide a better understanding of the US imaging anatomy, enabling more accurate needle placement and (during ablative therapies) a more precise monitoring of the treatment area. By using ultrasound throughout the procedure, rather than CT guidance, the patient's exposure to radiation is reduced. Compatible with B-mode, colour Doppler and dynamic Contrast Harmonic Imaging modes.
  • Real-time Bi-Plane (RTBi) Imaging
    This technology which simultaneously displays two images from two different transducers, on-screen, can be a supporting tool for liver and other interventional treatments. RTBi allows the interventionalist to have a better understanding of the needle position, to monitor the ablation process in two scan planes and to avoid excess ablation which can cause severe pain.
  • Dynamic Contrast Harmonic Imaging (dCHI)
    dCHI offers increased agent-to-tissue specificity, using a wideband pulse inversion technique which modulates both the phase and transmitted frequency range between pulses. Customised and factory presets are available for high and low MI techniques using first- and second-generation contrast agents. Features include the real-time, dual display of contrast harmonic and fundamental B-mode, with independent imaging parameter adjustment and the option to display biopsy guidelines on both images. Microbubble Trace Imaging, a bubble accumulation mode, is available with customisable destruction/replenishment protocols. On-board digital storage of images and clips is provided, along with the generation and analysis of time-intensity curves, for a more detailed evaluation of the contrast enhancement.
