Clinical data are mounting to show that radiofrequency ablation of small kidney tumors is a safe, effective alternative to open or laparoscopic resection. Distinct intervention protocols and complementary techniques could further boost RFA’s efficacy and expand its application to areas previously deemed unsafe.
Radiologists have seized control of imaging to measure bone mineral density, increasing their turf by 20% in a six-year period, according to researchers from Thomas Jefferson University.
The FDA wants to alter how PET radiopharmaceuticals are regulated, though the proposed changes may not take effect until 2008.
Today's log at the imaging center shows 15 patients scheduled for different examinations. Most come with abdominal or musculoskeletal symptoms, and almost half of them are overweight. The daytime sonographer called in sick earlier, so the radiologist needs to make a tough call: Does she perform 15 ultrasound exams herself or does she shuttle everyone through to any of the CT or MR scanners available?
Dr. James H. Thrall's column "Utilization management steps onto center stage" (July, page 29) carries the subtitle "Referring physicians and radiologists must wrestle decision making back from insurers," prompting the question, Was decision making usurped or abandoned? As chief medical officer of CareCore National, one of the aggravating "1-800 programs" Thrall refers to, I present a perspective from the other side.
Hysterectomy and myomectomy still dominate the uterine fibroid treatment options. But specialists, including gynecologists, are gradually gravitating toward minimally invasive alternatives. The pace for change may quicken when definitive long-term outcomes on uterine artery embolization are published later this year.
Ultrasound has long been a prime target in imaging turf wars because it does not employ ionizing radiation. Radiology lost cardiac ultrasound, and it is questionable that the specialty will continue to be a major player in obstetrics.
A clinical imaging study published in The New England Journal of Medicine on Sept. 16 could spark substantial new demand for full-field digital mammography.
As more physicians begin to use FDG-PET for diagnosing Alzheimer's disease, the demand for automated software systems that help interpret complex metabolic scans is increasing. Several new automated expert systems have been developed that can improve diagnostic accuracy and help assess risk for the disease.
Tracking information about workflow, payment, and outcomes has never been more important for breast imaging centers. Some clinical and technical data collection has long been mandated by the Mammography Quality Standards Act, and new recommendations by the Institute of Medicine could require centers to step up their efforts. But regulatory demands are not the only reason for breast centers to make the most of what information systems have to offer.
Advances in electronic image transmission have the potential to change the face of radiology. Using technology supported by PACS and radiology information systems, interpreting radiologists can provide timely services to multiple facilities while practicing "virtually" from almost any location. This capability has allowed entry of international teleradiology into the U.S. market, and it has opened the door to increased competition for interpretation contracts, even across state lines.
Digital mammography is more accurate than film in detecting cancer in women under age 50, those who have dense breasts, and in pre- and perimenopasual women, according to the long-awaited results from the Digital Mammography Screening Trial (DMIST).
PACS appears to be finally coming of age as institutions around the world increasingly recognize the benefits of electronic record keeping. The biggest providers of PACS, the film-turned-PACS vendors could expect this to be the time when they realize earnings from their decade-plus investment in this technology. But it is more complicated than that.
Thirteen years after its passage by Congress, the Mammography Quality Standards Act remains a sore subject for radiologists. While breast imagers unanimously agree that the MQSA has vastly improved mammography quality, they give the rule low marks for its cost and the burdensome details of compliance.
No doubt, the Mammography Quality Standards Act has improved the quality of breast imaging. As this month's cover story clearly establishes, long-time mammographers have seen a decided improvement in clinical practice since the MQSA was adopted in 1992.
Reimbursement for radiofrequency ablation of tumors continues to broaden, with local Medicare agencies and most major insurers covering the procedure for unresectable liver neoplasms. Palliative RFA treatment of bone metastases follows as the next most widely accepted procedure. These positions are bolstered by existing CPT codes for the treatments.
Much has happened in the year since the FDA approved the first MR-guided ultrasound device for the treatment of uterine fibroids. The pioneers of this new product area, InSightec and its imaging partner GE Healthcare, have launched initiatives to find other clinical applications. One is a pivotal trial of ExAblate 2000 for the treatment of breast fibroadenomas. Another combines two feasibility studies of the safety and efficacy of the device for ablating breast cancers and eliminating brain tumors through an intact skull.
The Centers for Medicare and Medicaid Services published today a new code that will reimburse hospitals for the use of tissue plasminogen activator, an effective thrombolytic. The shift will help hospitals recoup thousands of dollars lost each year from treating stroke patients.
Eastman Kodak will unveil a top-of-the-line, multicassette computed radiography system at this week’s meeting of the American Healthcare Radiology Administrators in San Antonio. Earlier this summer, the company unveiled a value-oriented single-cassette CR reader designed for budget-strapped hospitals, imaging centers, and physician practices.
Manufacturers and industry report a decline in the ultrasound market last year in the U.S. The market was down in 2004 about 7% to $950 million in equipment shipments, according to consolidated industry estimates. This decline came on the heels of a record year in 2003, during which vendors shipped equipment valued at just over $1 billion to U.S. customers. Backlogs for new units and upgrades from 2004 outdistanced sales by about 4%, indicating strength going into 2005.
The American College of Radiology, the Society of Breast Imaging, and individual breast imagers have criticized a report prepared for Congress that calls for sweeping changes to the Mammography Quality Standards Act. Even though the report includes recommendations to offset financial burdens incurred by centers adopting these new measures, mammographers want to see the money first.
The recent creation of the Society for Cardiovascular Computed Tomography may give birth to a new era of cooperation among radiologists and cardiologists that might also sound the death knell for electron-beam CT.
A Florida radiologist has been named as a defendant in a whistleblower lawsuit alleging Medicare fraud though improper lease arrangements, kickbacks, and upcoding.
The political heat surrounding diagnostic imaging has gone up several degrees over the last few years. The American College of Radiology’s political action committee is now a top financial contributor among healthcare organizations. The college regularly lobbies politicians on Capitol Hill and testifies before Medicare advisory panels regarding imaging issues. Congress responded in the spring by convening a special hearing to examine and possibly revamp imaging credentialing and reimbursement.
