Today’s economic environment makes it increasingly challenging for physicians and technologists to travel to educational events. Robb Young, senior manager in the CT Business Unit for Toshiba, explains that this obstacle inspired the company to begin sponsoring webinars on applications for its imaging technology. “Webinars are easier for people to access,” he says. “We can do them during the day, and we can make the expertise of a particular speaker available to a broader audience. A webinar can also be saved online, so if people missed it, they can easily access the information later.”

Toshiba’s first webinar in 2010 featured S. Bruce Greenberg, MD, professor of radiology and pediatrics at Arkansas Children’s Hospital, presenting on how radiology professionals and clinicians can leverage 320-detector row CT to reduce sedation needs and radiation exposure for patients while providing them with high-quality diagnostic images.  This webinar was so well received, that Dr. Greenberg conducted a second session in late February.  “We’re focusing on the needs in the market that drove the development of this technology,” Young says. “In pediatrics, obviously, that’s being able to image patients quickly at a low dose.”  This CME-accredited webinar will be available online in April.  At that time, please visit the following site to view the webinar and receive educational credits http://www.ceconcepts.net/CT/ .

Webinars planned for later in the year include sessions on using 320-detector row CT for cardiac care and stroke triage and diagnosis, as well as on applications and technology for non-contrast MRI. The webinars are each an hour long, are free to all attendees, and are accredited by the Accreditation Council for Continuing Medical Education. Each is worth one CME credit.

“We find these events are particularly beneficial for those who are looking at new applications of a technology, or who want to understand a technology better—especially because they get to hear about it from a user,” Young says. “The webinar format allows us to get the information out to those who need it more quickly and easily.”

At this year’s annual scientific meeting of the American College of Cardiology (ACC), which takes place on March 14–16 in Atlanta, Toshiba (booth #1944) will showcase a range of advances in and enhancements to its cardiac-imaging technology.  Following is an overview of what Toshiba will showcase:

Infinix-i Hybrid Lab

When performing patient procedures in a hybrid setting, it is critical that the imaging system provides the flexibility to quickly and easily access both the patient and ancillary equipment. Toshiba will showcase its Infinix™ VF-i vascular X-ray system with 12” x 12” flat panel detectors and CAT-880B hybrid catheterization table, designed to create a best-in-class hybrid suite.  The new mid-sized 12” x 12″ flat panel detector expands the versatility of the Infinix-i line that features a five-axis C-arm positioner and enables unprecedented patient access and coverage. Along with the new mid-sized detector, the Infinix-i five-axis systems are now available with the new CAT 880B tilt/cradle hybrid catheterization table. This table is designed to allow greater positioning flexibility and patient access during imaging and surgery. The table functionality, with side-to-side cradle and head-to-toe tilt, permits clinicians to angle the table in the optimal position to quickly and comfortably complete procedures. The system on display will also include ancillary equipment typically used in a hybrid suite.

Cardiac Ultrasound Capabilities

The cardiac capabilities of Toshiba’s ultrasound technology will also be featured. The Aplio Artida™ system is a dedicated cardiac system which provides unique 3D Wall Motion Tracking, allowing physicians to rapidly identify wall-motion defects and the timing of cardiac events, as well as real-time, multiplanar reformatting for assessing global and regional left ventricular function. Also on display is the new Aplio™ MX system, which is midsized and cart-based for better portability. Aplio MX is a multi-modality system which includes Differential Tissue Harmonic Imaging, for better results with bariatric patients; ApliPure, which enhances image clarity and detail definition; Advanced Dynamic Flow, which shows flow with directional information for even the smallest vessels.

Cardiac CT Software Enhancements

CT will highlight cardiac-software enhancements for the Aquilion^® ONE and Aquilion Premium, including new ONE Beat Prospective Reconstruction, which shortens the interval window and reduces radiation exposure time, reducing dose by 21 percent; Real Time Beat Control, which calculates the running real-time average of the heart rate to predict the next beat more precisely (and thus, to time the scan more accurately); and optimizing timing for ^SUREStart, which accurately determines contrast uptake time for a better image. Wide Volume Cardiac Protocol on the Aquilion ONE, a work-in-progress enhancement, will enable clinicians to image the entire heart, lungs, and aorta in two rotations.

Cardiac MR

The wide range of cardiac MR capabilities on the Vantage Titan™ and Vantage Atlas^® systems will be highlighted. The Vantage MRI product line offers a range of advanced cardiac capabilities, including a cardiac coil for the Vantage Titan and noncontrast imaging for patients with renal insufficiency.

The American Heart Association estimates that nearly one million US residents die of heart disease annually, and according to the US Centers for Disease Control and Prevention it is the leading cause of death for both men and women. As a result, finding ways to detect heart disease earlier and more accurately are becoming increasingly important. Toshiba’s advancements in MRI are helping physicians quantify heart disease, thus improving diagnosis and treatment.

MRI has long been used to assess the structure and morphology of the heart, but as the technology advances, so do the procedures available to clinicians for quick and accurate diagnosis of heart disease in their patients. “The bread-and-butter sequence is called SSFP [steady-state free precession] cine imaging,” Erin Kelly, clinical science manager for MRI at Toshiba America Medical Systems, explains. “It gives an image of the heart as it moves through the cardiac cycle to tell the clinicians how the muscles are functioning, and they can use these images to calculate ejection fraction and left-ventricular volume.”

The ability to perform SSFP cine imaging is one of many cardiac-friendly features included in Toshiba’s Vantage™ Titan MRI, a 1.5T system that also includes a 16-element cardiac coil that can be combined with the 32-element spine coil. The center elements are smaller, resulting in higher-resolution imaging of the heart, and “the elements in the coils can be turned on and off to optimize the signal-to-noise ratio,” Kelly notes. Various sequences and parameters are selectable from the scanner to facilitate successful evaluation of the heart, including delayed-enhancement, myocardial imaging, retrospective gating, black-blood imaging, and real-time motion correction to name a few. Non-contrast techniques are also available on all Toshiba MR systems. For example, Whole Heart Imaging is one contrast-free sequence that allows physicians to assess the coronary arteries without contrast.

Timothy Albert, MD, is medical director of the Cardiovascular Diagnostic Center at Salinas Valley Memorial Healthcare System, Salinas, California, and he uses the Vantage Atlas system. He says, “We try to use noncontrast imaging as much as possible, both for patient convenience and safety and because of concerns about patients with kidney problems. For scar imaging, you still need contrast, but the other stuff, we can often do without it.”

Albert says that MRI has an important place in the portfolio of modalities used to detect and plan treatment for heart disease. “I use CT for coronary imaging, but that’s a small part of the cardiac question,” he says. “MRI’s strengths are really in functional imaging—the shape of the heart and how it’s beating. There’s an increasing amount of scientific data coming out about new uses for MRI in cardiac care.” Albert and his team even run a two-day training course designed to help educate referring physicians on the robust applications of cardiac MRI.

“MRI is ideal for assessment of the heart-failure patient, looking at the potential causes to guide treatments and diagnostic tests, and we use it to determine whether someone would benefit from being revascularized after a heart attack,” Albert says. “For patients with congenital abnormalities, it’s the gold standard, since CT radiation could be cumulative over time. In the future, we hope physicians will hear about these new uses for MRI and recommend it more frequently.”

As procedure mixes continue to shift in facilities nationwide, it’s increasingly important for capital investments in imaging technology to offer versatility, according to Allen Berthe, X-ray senior product manager for Toshiba America Medical Systems. That’s why the company’s vascular labs come automatically equipped with features for cardiovascular procedures.

“One of our philosophies is that customers’ needs are changing and it is very likely a system will be required to perform cardiac and vascular procedures, so we’ve tried to gear our systems to maximize room utilization,” Berthe says. “A hospital today may know exactly what it wants, but five years from now, its staffing may change, its requirements may change, and its clinicians may like to do different types of procedures—so we created a system that would give them flexibility.”

Features that are part of the company’s vascular labs include digital subtraction angiography provided, standard, irrespective of system type or panel size, and a stepping feature that allows more efficient and accurate lower-body exams. A third feature is what Berthe calls a “true multitasking digital processor,” which, he explains, “means that if a physician comes in and wants to look at the images taken yesterday on a particular patient, he or she can do that without affecting the procedure currently in progress.” This parallel-processing capability is also included, standard, in Toshiba’s vascular labs.

Berthe notes that all labs are 3D ready; if a facility chooses to upgrade to 3D, the base system is configured to accept it, “so if your practice changes in three years, you can add it.” Labs are also optimized for fingertip-to-fingertip, head-to-toe patient access and coverage. “Our systems are designed to give you unprecedented patient access,” Berthe says. “Sometimes, cases require on-the-fly changes, and our systems can adapt to that. If there’s a lot of additional equipment around, then having an easy-to-position C-arm is really helpful.” He adds that all Toshiba systems are configured using the same base platform, the same features, the same user interface, and the same consoles. “If you’re buying multiple systems from us, you can go from room to room with high confidence because everything’s going to perform virtually the same way,” he says.

Berthe emphasizes the importance of versatile, flexible purchases in an environment of fluctuating reimbursement and potential health care reform. “We’re just making sure we give you a room that can address your clinical needs,” he says. “If you don’t have a cardiovascular program and choose to start one, you can do that. You have a system that’s ready to do it.”
