3 strategies to control wasteful imaging
January 8, 2019
- Educate patients Healthy individuals and patients can be educated abut radiation risks, intravenous contrast and the possibility of incidental findings. The use of flowcharts and diagrams may illustrate the potential “detrimental effects” of further testing, the authors added.
- Focus on the target Lowering the image sensitivity of anatomy that is not the primary target could result in fewer unrelated findings, the researchers wrote. Some may argue that the limited image may not allow for the radiologist to make an accurate diagnosis. The authors said, however, that this may be true for more complicated cases, but not for most patients.
- Ask radiologists to serve as gatekeepers Additionally, instead of just interpreting examinations, radiologists may also need to become “gatekeepers” to regulate what tests should be ordered or not ordered.

- 3D visualization, virtual reality and image-guided intervention: Startups in this space have been around for a long time and raised significant funds, the authors wrote. 3D printing, surgical simulation platforms and surgical prosthetics are just three examples of why these technologies are getting more and more attention throughout the industry.
- Intraoperative technologies: Alexander and colleagues warned all businesses serving imaging professionals that this is an area rapidly growing in importance. “Imaging is becoming a crucial aspect of intra-operative planning and execution, particularly for applications requiring extensive data acquisition in real time,” the authors wrote. “It can enhance precision during surgical interventions and improve outcomes. Intra-operative techniques span all modalities, including ultrasound, MRI, and fluoroscopy, and they often require portable capabilities.”
- Nuclear imaging: “As nuclear imaging grows and moves away from metabolic imaging for cancer localization to pathology-specific cancer diagnosis (for instance, the combining of ligands specific to prostate or breast cancer with radioisotopes for definitive diagnosis), imaging companies will have increasing opportunities to engage in cancer diagnostics, and potentially therapeutics as well,” the authors wrote.

3 strategies to control wasteful imaging
By: Subrata Thakar
Unnecessary imaging is a serious problem in the United States. So what can be done about it? A new analysis published in the Journal of the American Medical Association explored that very question.
The industry has combated unnecessary and wasteful diagnostic imaging by implementing appropriate use criteria and educating physicians, but more needs to be done. These are three strategies suggested by author John P. A. Ioannidis, MD, DSc, of the Stanford Prevention Research Center in California, and colleagues:
“Instead of the current typical pretest conversation, which generally involves a clinician simply notifying the patient that imaging is ordered, a shared decision-making process requires comprehension of the likely gains versus the potential detrimental effects of testing, including the detection and investigation of unrelated findings,” the authors wrote.
Shared decision-making, the authors wrote, allows for improved transparency and decreased confusion regarding follow-up and treatment. Also, communicative interventions may need to occur at multiple times during a single patient interaction so that patient safety is adequately addressed.
“Although this approach would not reduce the number of initial tests, it could potentially prevent the cascade of tests that follow an incidental finding,” the authors wrote.
“This would require embedding radiologists more routinely as consultants in clinical encounters that contemplate ordering imaging tests,” Ioannidis and colleagues noted.

Whole-body PET/MRI shows promise for staging high-risk prostate cancer patients
Whole-body PET/MRI shows potential to provide physicians with a “one-stop-shop” for staging high-risk prostate cancer patients, according to new research published in the Journal of Nuclear Medicine.
The authors compared the performance of 68 Ga-PSMA-11 PET/MRI with clinical nomograms currently being used to determine risk by conducting a retrospective study on 73 patients. Two common prediction tools—Partin tables and the Memorial Sloan Kettering Cancer Center (MSKCC) nomogram—and 68 Ga-PSMA-11 PET/MRI were used to predict each patient’s risk for advanced disease. Those predictions were then compared with various histopathologic results.
Overall, the whole-body PSMA-targeted PET/MRI imaging produced positivity rates comparable with both the Partin tables and the MSKCC nomogram.
“Our results showed that PSMA-targeted PET/MRI performed equally well to established clinical nomograms for preoperative staging in high-risk prostate cancer patients and provided additional information on tumor location” co-author Andrei Gafita, MD, of the Technical University of Munich in Germany, said in a news release from the Society of Nuclear Medicine and Molecular Imaging. “Translated into a clinical setting, the use of this imaging technique for preoperative staging might support treatment planning that may lead to improved patient outcomes.”

Antiquated X-Ray Machine leads to Ben Roethlisberger returning to game
On Sunday, December 19 NFL game between the Pittsburgh Steelers and Oakland Raiders, Steelers' quarterback Ben Roethlisberger was injured as a result of a sack by Raiders' defensive end Clinton McDonald. At half-time Roethlisberger had his ribs x-rayed. Because the X-Ray machine was out of date, the results were inconclusive, the team's General Manager Kevin Colbert delayed the quarterback's return to the game. Roethlisberger did end up returning to the game in which the Steelers lost.

2 key trends driving the future of medical imaging (and 3 to keep an eye on)
Artificial intelligence (AI) and blockchain are two titanic trends driving the future of medical imaging, according to an in-depth analysis published in the Journal of the American College of Radiology. The study’s authors also assessed other trends that continue to gain momentum.
“The medical device industry is undergoing rapid change as innovation accelerates, new business models emerge, and AI and the Internet of Things create disruptive possibilities in health care,” wrote author Alan Alexander, MD, and colleagues from the global consulting firm McKinsey & Company in New York City.
AI and blockchain: Leaders of the pack
Alexander et al. used data to explore the current state of the medical imaging industry and observed that AI and machine learning (ML) are, not surprisingly, the hottest ticket in town.
“This cluster has the greatest number of startups (32), the highest volume of investor transactions (more than $500 million), the greatest revenue, and strong investor interest and potential for further growth,” the authors wrote. “Furthermore, there has been keen interest from radiologists in improving work efficiency, given the number of specialty-specific publications, presentations, and opinion articles in this space.”
A lot of the companies in this space specialize in one specific modality, they added, with 22 percent of companies focused on CT and another 13 percent each focused on MRI and mammography.
“CT and mammography lend themselves most readily to AI because attenuation information can be used in the learning algorithms,” the authors wrote. “Other modalities present challenges: the interpretation of multisequence images in MRI, the user variability in ultrasound, and 2-D limitations in x-rays.”
AI and ML have the ability to help specialists interpret studies more quickly and some algorithms can even detect abnormalities “not readily visible to the human eye.” These technologies can also help with cost savings, the researchers noted, due to how they can prevent unnecessary readmissions and cut down on wasteful imaging.
Blockchain, on the other hand, is even newer than AI and ML. The authors noted numerous ways blockchain can help radiology.
“It could help prevent the kind of data breaches that have recently occurred in health care and, if breaches do occur, blockchain can enable continued functioning after the event,” they wrote. “The technology is likely to underpin further use cases for cyber- and data security in concert with data sharing, as well as AI computing through the use of ML algorithms across distributed ledgers. Blockchain will also support the distribution of graphics processing units to drive AI analysis and analytics and facilitate further ML endeavors.”
Another key reason blockchain is so important is that it can help imaging providers with the massive amount of data they are required to maintain and securely share with patients and other physicians. Blockchain has already helped the banking industry with its own “large data needs,” and it could do the same for medical imaging.

Konica Minolta Brings Motion to X-ray with Dynamic Digital Radiography at RSNA 2018
For the first time, radiologists will be able to view motion from standard X-ray images without fluoroscopy. Konica Minolta Healthcare is bringing digital radiography (DR) to life with the ability to visualize movement using conventional X-ray. Known as Dynamic Digital Radiography (DDR)* or X-ray in Motion™, this revolutionary new modality captures movement in a single exam and allows the clinician to observe the dynamic interaction of anatomical structures, such as soft tissue and bone, with physiological changes over time. The value of DDR in thoracic imaging is promising, allowing clinicians to observe chest wall, heart and lung motion during respiration. DDR goes beyond pulmonary function; Konica Minolta is exploring its use in orthopedic applications of the spine and extremities. This new capability will be showcased at the annual meeting of the Radiological Society of North America (RSNA), being held November 25-29 in Chicago, in Konica Minolta’s booth 1919.
“DDR may dramatically change the diagnostic and patient management paradigms for respiratory diseases and other pathologies including orthopedic injuries,” says Kirsten Doerfert, Sr. VP of Marketing, Konica Minolta Healthcare. “With X-ray images in motion, clinicians can see structures in a way they have never been able to see before, enhancing their ability to better manage patients based on individual characteristics and bringing precision medicine further into focus for radiology. The potential benefit is significant."
DDR is an enhanced version of a standard DR system that rapidly acquires up to 15 sequential radiographs per second for up to 20 seconds of physiological movement, resulting in 300 X-ray images with a dose equivalent to about two standard X-rays. Since the DDR system also performs all conventional X-ray studies as well as motion radiographic studies, it is a cost-effective solution that provides greater diagnostic capability in an economical package.
In the US, 74% of all radiologic studies are radiography1 and nearly 44 percent of hospital-based X-ray imaging exams are thoracic2. While access to CT, MR and nuclear medicine may be limited in regions throughout the world, X-ray is an essential primary diagnostic tool that is widely available in developed nations at a fraction of the cost. There are also potential cost savings for healthcare systems globally by reducing the need for more advanced, and more expensive, imaging techniques.
“We are enabling clinicians to see more than a static image," says Guillermo Sander, Director of Marketing, Digital Radiography, Konica Minolta Healthcare. "By digitally capturing movement, DDR may deliver quantifiable clinical information that has the potential to increase the quality and specificity of diagnosis. With DDR, clinicians may better understand the pulmonary effect of neuromuscular disorders, diagnose and manage patients with respiratory conditions, such as asthma or chronic obstructive pulmonary disease (COPD), and evaluate post-operative changes in patients with lung cancer, lung cysts and other pathologies."
Konica Minolta developed DDR with the global healthcare goals of higher quality care, greater access and lower cost in mind, supporting clinicians throughout the world in making better decisions, sooner.
