Radiological exams on pregnant women increase by 81% over 10-year period
November 28th 2007Utilization rates of radiological examinations in pregnant women rose dramatically over the last decade, driven largely by CT studies of the head and CT pulmonary angiography (CTPA). In one of the first studies to evaluate rates of radiological examinations that expose pregnant women to ionizing radiation, the number of exams per patient population was found to have risen by 81% over the period, according to research presented at the RSNA meeting by Dr. Elizabeth Lazarus of Brown University.
Image Vault offers self-contained PACS
November 28th 2007American Medical Sales is showcasing at RSNA 2007 an all-in-one PACS product that combines display, processing, and storage. Listed at $8000, the new Image Vault hardware/software combo is designed for small imaging operations. It features a simplified user interface built into a touchscreen, fingerprint security key, and automated logoff.
Fractures and liver/kidney lesions top list of residents’ ER misses
November 28th 2007A research team from Iowa has found that bone fractures, hypo- or hyperdense lesions in the liver and kidney, pulmonary nodules, and gastrointestinal wall thickening or fat stranding are among the most common misses by on-call residents in the emergency room.
Emageon show PACS upgrade, RadSuite
November 28th 2007New capabilities debuting at the RSNA in the Emageon booth include productivity enhancements in and beyond radiology. Product enhancements extend the company’s Enterprise platform offerings for multisite PACS to teleradiology, while expanding its mainstream PACS into mammography.
CT, MR-guided injections promise pain relief for sacroiliac joint lesions
November 28th 2007Injections of corticosteroids and anesthetics guided by CT or MR imaging offer a reliable therapeutic option for the treatment of chronic lower back pain from sacroiliac joint lesions, according to researchers from Germany and the U.S.
Performance data help justify breast MRI’s whopping price tag for high-risk screening
November 28th 2007MRI has outrun other modalities in a screening trial involving high-risk women. Such research helps justify an estimated $1.4 billion a year in direct costs for the U.S. if new American Cancer Society guidelines are followed.
Smaller FOV cuts dose but maintains sensitivity for detecting pulmonary emboli
November 28th 2007An abbreviated field-of-view can lead to a 48% cut in radiation dose for CT pulmonary embolism exams and 96% dose reduction compared to full-view 64-slice CT triple rule-out without affecting the diagnostic sensitivity of either procedure.
Siemens robot revolutionizes interventional imaging
November 28th 2007Siemens Medical Solutions demonstrated on the RSNA exhibit floor a novel marriage between industrial robotics and advanced C-arm technology. Its new work-in-progress, Artis zeego, is based on technology developed for heavy equipment manufacture.
Whole-body staging with MRI, PET/CT can miss many melanoma metastases
November 28th 2007In a surprising discovery, researchers from Germany have found that whole-body staging of patients with recently diagnosed malignant melanoma using either MRI or PET/CT could miss a substantial number of metastatic lesions.
Study builds argument for CCT triple rule-out to screen chest pain patients in ER
November 28th 2007Thomas Jefferson University researchers have demonstrated that a 64-slice CT triple rule-out exam can, with 99.3% certainty, dismiss the presence of acute coronary syndrome in the emergency room for chest pain patients at mild or intermediate risk for ACS. The test also diagnosed pulmonary emboli and other noncardiac sources of the patients’ discomfort.
Thoracic and GI anatomy present challenges to malpractice suit avoidance
November 27th 2007Cancer of the lung is overwhelmingly the most common cause of suits involving thoracic disease, outdistancing by far any other condition within the confines of the thoracic cavity. Conversely, failure to diagnose gastrointestinal conditions is an uncommon cause of suits against radiologists, but perforated viscus awards are much higher than for other gastrointestinal conditions.
Imaging techniques fine-tune upper extremity MSK diagnoses
November 27th 2007Magnetic resonance arthrography (MRA) and ultrasound bring different strengths to imaging and treating joint injuries and stresses, according to research presented at the RSNA meeting. Contrast-enhanced ultrasound is a superior method of assessing of neovascularity in patients with lateral epicondylitis, while MR can detect signs of recurrent carpal tunnel syndrome after surgery. A combination of MRI and ultrasound may be the most effective solution for imaging medial elbow pain.
Novel DR system captures whole-body images
November 27th 2007Biospace Med is showing off an innovative low-dose, high-contrast EOS digital x-ray system that uses two matched sets of x-ray tubes and detectors. Designed specifically for whole-body scanning, the system relies on orthogonally mounted x-ray chains that scan the standing patient and acquire data in continuous top-to-bottom motion.
