• HITACHI Real-time Tissue Elastography (HI-RTE)
  In breast applications, HI-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 BI-RADS 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.
  Using an endoscopic approach, HI-RTE of the pancreas and lymph nodes has been shown to further define the characteristics of benign and malignant lesions and can be used to guide biopsy sampling for diagnosis.
  Within the thyroid gland, HI-RTE displays 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 HI-RTE can provide additional diagnostic information include the liver, endoanal, musculoskeletal, prostate and testes.
• Hitachi Real-time Virtual Sonography (HI RVS)
  Offering a real-time simultaneous display of the CT or MRI scan plane which corresponds to the ultrasound image, HI 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
  The 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 the 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.
• Diagnostic and Therapeutic Endosonography
  Over the last ten years, the diagnostic importance of endoscopic ultrasound has increased consistently. Modern endosonographic imaging represents a minimally invasive procedure, delivering high-resolution images and significantly contributing to therapy decisions and determining follow-up surgical strategies. Hitachi offers electronic radial 360° echoendoscopes for diagnostic EUS and longitudinal scopes, available with integrated working channels from 2mm to 3.8mm (max), for therapeutic examinations such as FNA and cyst drainage. The application of high-frequency mini probes, for mucosal examinations, intraductal ultrasound of the pancreatic system and specialist applications, significantly improves the system's diagnostic capabilities.
