CT's impact in diagnosing appendicitis depends on clinical likelihood
October 23rd 2008Clinical experience shows that diagnostic CT reduces the incidence of negative appendectomies. Those skeptical about the application's safety, however, may find ammunition in a recent prospective study that suggests CT may be unnecessary when appendicitis is unlikely.
Europeans face potential Mo-99 supply nightmare; key nuclear reactor closed until February 2009
October 14th 2008The Nuclear Research and Consultancy Group (NRG) has announced that the High Flux Reactor in Petten, the Netherlands, will remain shut down until Feb. 16, 2009, raising the possibility of another four months of molybdenum-99 shortages for thousands of European nuclear imaging services.
European radioisotope supply woes continue
September 30th 2008The High Flux Reactor in Petten, the Netherlands, the primary source for the molybdenum-99 crucial to diagnostic nuclear imaging in Europe, will remain shut down until at least the end of November while officials devise a strategy to plug a gas leak.
Nuclear medicine dosing for kids varies widely
September 9th 2008A Boston Children's Hospital survey of 16 selected procedures at 13 pediatric hospitals in North America found a wide variation in radiopharmaceutical doses administered during nuclear medicine exams. The report reveals a need for consensus among nuclear physicians on appropriate doses for young patients.
SPECT/CT replaces standard detector with flat-panel x-ray
August 1st 2008Philips Healthcare put a new twist on SPECT/CT with the unveiling at the SNM meeting in June of a hybrid that incorporates a flat-panel x-ray system in place of the typical multislice CT. The novel combination is attuned specifically to the needs of specialists in nuclear medicine, said Jay Mazelsky, senior vice president and general manager of Philips nuclear medicine.
MDS files $1.6 billion suit over abandoned Mo-99 reactors
July 9th 2008MDS has filed a $1.6 billion breach of contract lawsuit against Atomic Energy of Canada Ltd. and the Canadian government for their decision in May to halt development of a twin nuclear reactor complex designed to provide a long-term supply of molybdenum-99, to be refined and distributed by MDS.
Study finds huge variations in pediatric nuclear medicine dosing
July 2nd 2008A survey of children’s imaging services has found a twofold variation in radiopharmaceutical doses administered during pediatric nuclear medicine exams. For some radiopharmaceuticals, the reported maximum activities varied by as much as a factor of 10, and minimum activities differed by as much as a factor of 20, suggesting the need for a consensus among nuclear physicians on appropriate doses for young patients.
Clinical evidence secures reprieve for coronary CTA
July 1st 2008Pending clinical trial results played a pivotal role in the Centers for Medicare and Medicaid Services' decision in March to set aside plans to establish a national payment policy for outpatient multislice coronary CT angiography. Other published trials advanced our understanding of how nuclear cardiology, echocardiography, and cardiac MRI fit in evolving diagnostic practice.
Radiology societies seek Medicare coverage for CT colonography
June 24th 2008Several radiology-related professional societies have joined forces to urge the Centers for Medicare and Medicaid Services to approve national Medicare coverage for CT colonography to screen patients for colorectal cancer.
Report from SNM: Society protests Medicare reimbursement policies
June 18th 2008Society of Nuclear Medicine officials say the Centers for Medicare and Medicaid Services is manipulating the definition of radiopharmaceuticals to artificially deflate its payment rates for radioactive imaging agents essential to nuclear and molecular imaging practice.
Report from SNM: PET avoids unnecessary liver resection for metastatic colon cancer
June 17th 2008Liver resection for metastatic colon cancer is painful and debilitating enough, without a patient’s subsequent discovery that the surgery did nothing to halt disease progression. A multicenter prospective trial presented Monday at the Society of Nuclear Medicine conference in New Orleans found that FDG-PET prevents unnecessary surgeries for one of six patients who undergo liver resection based on CT findings.
Report from SNM: Images of the Year cover molecular imaging from head to toe
June 17th 2008Dr. Henry J. Wagner Jr. has selected two images, a PET/CT scan showing the early metastatic spread of tumor in a patient’s ear and a SPECT/MRI study of osteomyelitis in another patient’s foot, to exemplify the diagnostic capabilities of nuclear medicine as the 2008 Society of Nuclear Medicine Image of the Year.
Report from SNM: PET/CT restaging alters management for one-third of breast cancer cases
June 16th 2008FDG-PET/CT is gaining attention for its role in staging and restaging breast cancer. A trial from the Technical University of Munich, presented Sunday at the 2008 Society of Nuclear Medicine meeting in New Orleans, found that PET/CT detected local or distant recurrence in 67% of breast cancer patients and changed the management plan in 33% of the cases.
