Like much of healthcare, radiology is a state of flux. From reimbursement cuts to adopting EMRs, day-to-day operations are being transformed. Dictation software is evolving in the radiology field as natural language processing (NLP) is being developed to harness content from dictated, free text into a manageable report that can be used in radiology.
Phoenix-based Valley Radiologists has renewed its iSite PACS contract with Philips Healthcare for the next five years for its image management and storage needs.
Magnetic resonance (MR) pulmonary angiography should be considered only at centers that routinely perform the procedure well and only for patients for whom standard tests are contraindicated, according to the prospective PIOPED III study, published April 6 in the Annals of Internal Medicine.
Despite physician practices being broadly consistent with recommendations in the medical literature, there are variations by physician specialty and geographic location that may highlight evidence of inappropriate imaging in the diagnosis of pulmonary embolism (PE), according to a study published online in the April issue of the American Journal of Roentgenology.
Previous studies suggest that for patients with a suspected blood clot in a deep vein of a leg, withholding anticoagulation therapy after a negative whole-leg compression ultrasound is associated with a low risk of developing a blood clot during the subsequent three months, suggesting that multiple ultrasounds may not be necessary for low-risk patients, according to a report in the Feb. 3 issue of the Journal of the American Medical Association.
CT is being utilized as an adjunctive tool in the evaluation of patients presenting with complicated H1N1 flu cases in hospitals, which can be positive for both the technology and medical imaging agent manufacturers, said life sciences market research group Kalorama Information.
In the diagnosis of pulmonary embolism, CT scanning is the preferred technique of emergency room (ER) physicians and advised by radiologists by an overwhelming majority, according to a study in the January issue of the American Journal of Roentgenology.

Ventilation perfusion (VQ) scanning provides good diagnostic value in excluding pulmonary embolism (PE) during pregnancy, and may be utilized as a first line investigation for the condition, according to a study presented at the Radiological Society of North America (RSNA) annual conference in Chicago earlier this month.
Research published in the December issue of the Journal of Nuclear Medicine suggests that SPECT, when combined with low-dose CT, can provide an accurate diagnosis for pulmonary embolism.
A handheld decision-support system may improve diagnostic decision making for patients with suspected pulmonary embolism (PE) in the emergency department, suggests a study published in the Nov. 17 online edition of the Annals of Internal Medicine.
The use of catheter-directed thrombolysis saves lives and should be considered a first-line treatment option for massive pulmonary embolism, according to a study in the November issue of the Journal of Vascular and Interventional Radiology.
Lung scintigraphy is more reliable than CT pulmonary angiography (CTPA) in identifying or excluding pulmonary embolism in pregnant patients, according to a study in the November issue of the American Journal of Roentgenology.
Researchers using CT scans have found that patients with severe cases of the H1N1 virus are at risk for developing severe complications, including pulmonary emboli, according to a study to be published online today in the American Journal of Roentgenology.
CT angiography (CTA) can identify abnormalities and injury beyond the pulmonary arteries, including broken bones and heart disease in pediatric patients, according to a study published in the September issue of the American Journal of Roentgenology.
An evaluation of coronary artery disease (CAD) on an Apple iPhone has high sensitivity and negative predictive value among evaluable arteries, according to a proof-of-concept study presented at last week's Society of Cardiovascular Computed Tomography (SCCT) meeting in Orlando, Fla.
Since the Appropriateness Criteria for cardiac CT (CCT) was published in 2006, the modality has experienced rapid growth in technology and clinical use. When the American College of Cardiology (ACC) formally reviews the criteria next year, there might be room to add more indications to the "appropriate" category, including the "triple rule-out" exam, according to a study presented at the Society of Cardiovascular Computed Tomography (SCCT) meeting in Orlando, Fla., last week.
Lowering the peak kilovoltage setting for pulmonary CT angiography leads to superior vascular enhancement without a deterioration of image quality, according to the results of a retrospective study published in this month’s American Journal of Roentgenology.
Educating physicians about ventilation-perfusion (V/Q) scanning as an alternative to CT for the diagnosis of pulmonary embolisms led to a 23 percent decrease in patient exposure to radiation, according to a study presented today in Boston at the 2009 annual meeting of the American Roentgen Ray Society.
D-dimer screening is not used according to established diagnostic algorithms to determine the need for multidetector CT (MDCT) in diagnosing acute pulmonary embolism (PE) in emergency departments, based on findings of a single-center study in the May issue of the American Journal of Roentgenology.
The FDA has granted 510(k) clearance of the NeuViz 16 multi-slice CT system to Neuisys Imaging System Solutions.
