CHICAGO - Mallinckrodt has added two new contrast delivery systems. A compact power contrast injector, OptiStat is suitable for CT, general x-ray, and intravenous pyelography (IVP) procedures, as well as CT mobile coaches, according to the St. Louis-based vendor.
OptiStat can be used independently or interfaced to a larger, full-featured CT injector, Mallinckrodt said. Users can also deliver large volumes of contrast or saline following a contrast injection. In addition, OptiStat can serve as a back-up injector when a facility's primary CT injector is experiencing downtime, the company said.
In other new contrast injector introductions, Mallinckrodt has launched Optistar LE, an AC-powered MR contrast injector. Mallinckrodt said it has incorporated an enhanced user interface into Optistar LE along with a touchscreen console, allowing for easy setting of the injection rate and amount of contrast or saline.
An independent, dual-syringe powerhead can accommodate a full line of disposable and prefilled syringes, the firm said. Both single or dual phase injections can be performed.
In urology, Mallinckrodt has added a dual-monitor viewing option to its Liebel-Flarsheim Hydra Vision DR urological imaging system. The dual, 18-inch diagonal monitors can be moved via a triple articulating arm. The system's images can be sent within the hospital via a DICOM-compliant PACS network, archived on an optical disk, or transmitted via phone lines using an existing teleradiology network, according to the company.

![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&fit=crop&h=100&q=70&w=100)
