4-D PET/CT May Produce Inaccurate Tumor Imaging Unless The Patient’s Respiratory Pattern Is Highly Stable

A study presented at SNM’s 58th Annual Meeting focuses on the effect that breathing irregularities have on the accuracy of 4D positron emission tomography (PET) scans and outlines a PET imaging method that reduces “motion artifacts” or image blurring arising from respiratory motion…

CT Angiography May Be Unnecessary In Patients With Suspected Pulmonary Embolism

A new study suggests that computed tomography (CT) angiography might be unnecessary in many patients suspected of having pulmonary embolism (PE), based on the results of risk assessment analysis. PE risk assessment could help reduce radiation exposure and costs associated with CT angiography. The results of the study appear in the online edition and August print issue of the journal Radiology...

Practice Patterns In The Diagnosis Of Pulmonary Embolism Vary, Study Suggests

The imaging tests used in the diagnosis of possible pulmonary embolism (PE) vary by physician specialty and geographic region, which suggests that some of this imaging may be inappropriate, according to a study in the April issue of the American Journal of Roentgenology. PE, the formation of a blood clot in the lung, is the third-leading cardiovascular cause of death...

Simple, Educational Intervention Reduces CT Scans And Patient Radiation Exposure

A large New York medical center reduced the number of CT scans and radiation dose delivered to emergency department patients with suspected pulmonary emboli (PE) by holding collaborative educational seminars for staff and routing patients to CT pulmonary angiography (CTPA) or ventilation perfusion (V/Q) scanning based solely on their chest X-ray results, according to a study pu...

Cost Savings And Decreased Radiation Exposure With On-Demand Chest Radiographs For Mechanically Ventilated Patients

An article published Online First and in a future edition of The Lancet reports that when on-demand radiographs are dictated by the patient's clinical status, the number of radiographs carried out is a third less, without compromising patient care or safety. Current guidelines recommend routine daily chest radiographs for mechanically ventilated patients in intensive care units.

New Beryllium Reference Material For Occupational Safety Monitoring

Researchers at the National Institute of Standards and Technology (NIST), in collaboration with private industry and other government agencies, have produced a new reference material for beryllium. Beryllium, an exotic rare-earth metal used as a hardener in high-performance alloys and ceramics, can cause berylliosis - a chronic, incurable and sometimes fatal illness.

News From The August Issue Of Chest

X-RAY MACHINES MAY SPREAD INFECTIONS IN THE ICU Poor infection control practices when using x-ray machines may lead to nosocomial infections in the ICU. In a new study, Israeli researchers observed 173, 113, and 120 ICU chest x-rays during observation, intervention, and follow-up periods, respectively. Adequate infection control was practiced during 1 percent of observation x-rays, 42 percent of intervention x-rays, and 10 percent of follow-up x-rays.
