Low back pain is so common a complaint that physicians increasingly are recommending against invasive therapy for any but the most serious cases. This approach has led researchers to back up a step in patient management and crunch the numbers behind the imaging procedures that are done to assess and monitor this condition. It’s not good news for radiology.

Just as arterial calcium predicts coronary artery disease, the presence and extent of fat accumulations around the heart may indicate the presence of atherosclerosis.

Japanese researchers have established by studying nearly 500 patients that ultrasound is just as useful as CT in diagnosing intraperitoneal free air in patients suffering from abdominal pain or acute injury.

A decision by the Centers for Medicare and Medicaid Services to deny reimbursement for CT colonography screening has shocked radiologists. News that CMS had deemed evidence inadequate to grant coverage left imagers not only dismayed but in disbelief.

The Centers for Medicare and Medicaid Services has proposed that payment for CT colonography be declined, saying there is not enough evidence to support it as a colorectal cancer screening tool.

Multislice CT angiography can save lives by identifying occult congenital cardiac anomalies and disease that could lead to sudden cardiac death among competitive athletes.

Fusion PET/CT detects an additional one-fifth of active lesions from the supraclavicular notch to the adrenals that are not found on chest CT alone, according to a retrospective study.

An international clinical trial involving 50 healthcare facilities and nearly 2000 patients has found that physicians often do not apply available dose reduction strategies in procedures, resulting in a wide variation in radiation exposure.

Vaccines, antibiotics, and other therapeuticagents have kept most infectious diseasesunder control in industrialized nations. Indeveloping countries, however, infectious diseaseshave been harder to contain.

An experienced radiopharmaceutical manufacturer and a leading nuclear power plant builder have joined forces to bring back molybdenum-99 production to the U.S.

The production of molybdenum-99 at the High Flux Reactor in Petten, the Netherlands, may begin again in February, signaling the end to a five-month shortage of medical isotopes essential for nuclear imaging at medical facilities throughout Europe.

A National Research Council panel has concluded that commercial volumes of molybdenum-99 can be produced cost-effectively with low-enriched uranium. Mo-99 is the precursor of technetium-99m, a radioisotope used in most nuclear imaging procedures. The finding establishes a framework for weaning manufacturers of their reliance on nuclear bomb-grade uranium for Mo-99 production.

Researchers at a private diagnostic imaging center in central Florida have shown 3T MRI of the wrist is nearly as sensitive and specific as arthroscopy for detection of wrist ligament tears. MR could spot abnormalities missed by standard imaging tests and avoid needless surgeries, according to the investigators.

A study from the Institute for Energy and Environment Research indicates that U.S. radiation exposure regulations and compliance assessment guidelines often underestimate the risk of radiation for women and children because they are based on standards of a “reference man,” a hypothetical 20- to 30-year-old white male.

The creators of CT screening colonographyhave not waited for the medicalestablishment and insurers to accept itas an alternative to optical colonoscopy.

Nuclear medicine physicians at Mount Sinai Medical Center in New York City have reported encouraging results with dual-isotope SPECT/CT for accurately diagnosing and localizing infection in the feet of diabetic patients.

Medicare’s outpatient imaging program has issued a New Year’s greeting in the form of rules in the 2009 Physician Fee Schedule that raise professional reimbursement rates, expand the discount for contiguous body part imaging to more applications, and introduce anti-markup rules that are far less harsh than those originally proposed.

Increased use of CT to image pneumonia is unlikely to be the sole cause of increased hospital costs for pneumonia patients, according to a study from Brigham and Women’s Hospital in Boston.

Efforts to raise awareness about the associated risks of CT-based radiation exposure and the need to keep children from receiving unnecessary scans seem to be achieving traction among healthcare providers, according to a study by Ohio researchers. Their findings suggest that such increased awareness may make referring physicians less likely to order imaging that involves ionizing radiation for young patients.

The production of molybdenum-99 at the High Flux Reactor in Petten, the Netherlands, is unlikely to restart in February 2009 as had been planned, according to the facility’s operators, the Nuclear Research and Consultancy Group.

Despite encouraging earlier results, the much-awaited follow-up phase III DIAS-2 trial did not show any improvement in clinical response at 90 days for ischemic stroke patients who were given either of two doses of desmoteplase up to nine hours after the onset of symptoms of stroke compared with those who were given placebo.

Recommendations from an Oregon Health and Science Center study have clashed with the findings from a University of Wisconsin trial on the value of polypectomy for small polyps identified during CT colonography. The Oregon study calls for immediate resection while the Wisconsin trial concludes that removal would be costly, risky, and, by definition, unnecessary.

Educational efforts to raise awareness about the associated risks of CT-based radiation exposure and the need to keep children from receiving unnecessary scans seem to be achieving traction among healthcare providers, according to a study by Ohio researchers. Their findings suggest that such increased awareness may make referring physicians less likely to order imaging that involves ionizing radiation for young patients.

Discovery PET/CT 600 debuted at the RSNA meeting, taking a midtier position in GE Healthcare’s family of hybrid devices.

A lesion’s type and location, and the number of muscles that a needle has to pierce to reach it, rather than the number of procedures, determine the level and duration of pain after radiofrequency ablation of osteoid osteomas, according to Mayo researchers.

A low-cost 16-slice scanner designed for cost-constrained customers debuted at the Philips booth during the RSNA meeting.
