RSNA Scientific Session: Improve the Detection of Lung Nodules and Pneumothorax

Zhimin Huo, Carestream

If you left RSNA early, you may have missed a presentation today titled, “Rib Suppression Technique for an Enhanced Interpretation of Chest Radiographs.”

Don’t worry, though – you can read a summary of it here:

Chest radiographs are the most commonly used exam by clinicians for screening and diagnosing lung diseases. Studies have shown that rib suppression improved the detection rate of lung nodules, so Carestream developed a rib suppression technique that works well for portable chest radiographs including AP chest images. This can potentially improve the detection of both lung nodules and pneumothorax, especially for portable AP images.

Overall, the initial assessment of the rib suppressed images showed that current rib detection is sufficient for our suppression techniques. The rib suppressed images will be evaluated visually in terms of an increased visibility on lung nodules and pneumothorax by a group of radiologists.

The presentation concluded that the rib suppression technique can potentially improve the detection of both lung nodules and pneumothorax, especially for portable AP images.

RSNA Hot Topics: Portable Imaging and Radiology’s Transformation

Todd Kranpitz, Executive Director of Radiology at Iowa Health, Des Moines, visited our social media broadcast center at RSNA to offer his thoughts on the transformation underway in radiology.  Kranpitz feels its important that the radiology professionals become educators and reach out to other specialties to ensure they understand ALL that diagnostic imaging can bring to the table throughout the care continuum.

Also, Kranpitz recently acquired a CARESTREAM DRX-Revolution Mobile X-Ray System and shares his feedback on the impact of the portable unit on technologist productivity. He also discusses how surgeons want the technology and he sees the potential to replace c-arm systems in the operating room with a DRX unit.

RSNA Presentation: Carestream’s DRX Improves Image Quality, Workflow and Turnaround

Jim Sehnert, Carestream

In case you missed it, a presentation at RSNA today was centered on the added benefits that digital radiography brings to healthcare facilities. If you weren’t able to make it, here are the main findings:

Recently, a study was conducted at Massachusetts General Hospital in which chest images of 80 ICU patients were collected. Radiologists compared CR images to images of the same patient taken with a Carestream DRX-Detector. The team found that the DR images were clearly better than CR images for visibility of tubes and lines, and the edge-enhanced DR images were helpful in evaluating the patients. They concluded that the use of wireless DR for chest radiography in the ICU can provide similar or better information compared to CR—while enabling quicker turnaround time and smoother workflow.

RSNA Session Recap: Improve Image Quality While Decreasing Dose

Jackie Whaley, Carestream

Three studies by Carestream R&D presented at RSNA this week featured some of  our latest work to reduce patient dose exposure:

First, “Maximizing Lesion Conspicuity in Chest Radiography: Application of Low-Energy X-rays with Rib-contrast Suppression” was presented on Monday.

The study evaluated the use of low-kVp imaging in combination with rib-contrast suppression (RCS) to improve and maximize the appearance of lesions in chest x-rays at the same patient dose. A cesium iodide Carestream DRX detector was used in the study, which concluded that anatomy contrast and lesion visualization can be maximized when lower kVp is used in combination with rib-contrast suppression. Low kVp with RCS can be used to maximize the diagnostic quality of chest X-rays while maintaining the same patient dose, or to reduce the patient dose while maintaining the same diagnostic quality.

Second, “Task-Specific Dose Reduction for Neonatal Chest Imaging Using a CsI Direct Radiographic (DR) Detector” was presented on Tuesday.  The study was designed to determine the dose reduction potential in neonatal ICU imaging using a Carestream cesium iodide DRX detector. Pediatric radiologists independently marked the location of three features in each image: carina, endotracheal tube tip (ETT), and largest pneumatocele. The study concluded that while currently neonatal patients receive an effective dose of 15-20 µSv for chest exams, employment of task-specific techniques such as a low-dose ETT study and a higher-dose lung parenchymal study could promote dose reduction without affecting diagnosis. These findings are important because of the challenges of acquiring diagnostic quality radiographs of neonatal patients at the lowest possible dose.

Also on Tuesday, “Neonatal and Pediatric, Portable, Digital-Radiographic AP Chest Imaging: Weight-specific kVp Selection to Optimize Effective Dose and Image Quality” was presented. Pediatric patients are particularly sensitive to X-ray dose. This study evaluated the ability for physicians to detect small lung nodules imaged with a wireless Carestream DRX cesium iodide detector. The goal was to evaluate overall imaging performance to identify the best kVp as a function of weight. Typically, neonatal patients of less than 3 kg are imaged at or above 60 kVp. This study presents evidence that they should be imaged a lower kVp to optimize imaging quality and effective dose.

RSNA 2012: Patient Engagement Helps Imaging Center Differentiate and Grow

Erica Carnevale

Erica Carnevale, Digital Media Manager, Carestream

An article in Forbes.com recently explored a timely question that is on the mind of those of us at RSNA, “Is there a business case for engaging patients?”

Throughout the halls of McCormick Place you’ll hear lots of consensus on the positive impact of patient empowerment on consumer health—no surprise at a meeting themed “Patients First.” But you’ll also hear lots of questions about the administrative burden, controlling costs and return on investment.

At RSNA I spoke with Dr. Randall A. Stenoien, who is also CEO of Houston Medical Imaging, about his experience empowering and engaging his patients with Carestream’s MyVue* Patient Portal and the impact on his business.

Diagnostic imaging in Houston is extremely competitive—Dr. Stenoien faces competition from large provider networks, hospitals and the Texas Medical Center. At the same time, a number imaging centers and family practices were purchased by hospitals. Houston Medical Imaging saw  a number of its referrals disappear. Differentiating its services became paramount.

Dr. Stenoien knows he can compete with hospitals on price. He can compete on quality. But he needed to bring something different to the table. MyVue gave him a way to engage with patients in a way that none of his competition can match, putting them 100 percent in control and empowering them to be better healthcare consumers.

This engagement is buoyed by the fact that they now see more referrals being driven by patients versus physicians. Patients saw Houston Medical doing something a little different and request to be referred—Dr. Stenoien is seeing business growth as a result.

For Houston Medical Imaging, the business case for patient engagement is strengthened with streamlined operations and cost savings. Dr. Stenoien estimated his current image sharing costs at $9 per CD. With 5 percent of his patients getting access to the patient portal that’s significant cost savings in the first year.

Dr. Stenoien shares more about his MyVue trade trial experience in the video below:

What additional factors should be part of the business case equation?
