CT

Philips 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.

The number of students taking radiography and radiation therapy examinations for the first time slowed in 2007, signaling that educational programs are scaling back admissions and the pool of qualified technologists is meeting practice demand. Only nuclear medicine saw a sharp increase -- 17.1 % over 2006 -- although those numbers too are expected to decline, according to the American Registry of Radiologic Technologists.

MDS 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.

A 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.

Pending 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.

Several 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.

Society 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.

Liver 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.

Dr. 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.

FDG-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.

The crash of the radioisotope supply last winter gets a close look in this month's cover story. It details the politics and policy issues that closed down the Chalk River reactor in Ontario for nearly a month, leaving North American nuclear medicine physicians without a reliable supply of technetium-99.

Knowledgeable Canadians considered the molybdenum-99 crisis of 2007 a national disgrace. A squabble between the Canadian Nuclear Safety Commission and Atomic Energy Canada, the federal corporation that owns and operates nuclear research facilities at Chalk River, ON, forced the National Research Universal reactor there to shut down. That action triggered a crisis that cut off production of molybdenum-99, the isotope that produces technetium-99m for thousands of health facilities across Canada and the U.S.

Atomic Energy Canada has halted development work on twin reactors at Chalk River, ON. They were the planned successors for an aging research nuclear reactor that is the source of molybdenum-99 isotope used in 19 million nuclear medicine imaging procedures annually.

Persistent ground-glass nodules in the lungs are worth a closer look, as they are highly associated with malignancy. Dr. Anne Leung offered an overview of how these lesions present on CT imaging at the 2008 Stanford International Symposium on Multidetector-Row CT in Las Vegas.

Truly flat or depressed colorectal polyps pose a diagnostic dilemma and are always worth a closer look. A study in the Journal of the American Medical Association may have overstated the case, however, by concluding that these polyps were quite common and carried an increased cancer risk, according to CT colonography experts.

Academic radiologists who helped invent CT colonography are urging their community-based colleagues to gear up for a possible jump in public demand for CTC following the American Cancer Society's decision in March to add the procedure to its list of preferred colon cancer screening options.

A preliminary study indicates that first-pass and delayed-enhancement myocardial CT correlate well with measures of infarction size gathered with equivalent cardiac MR procedures.
