Philips' first quarter offers hope for better imaging marketplace
For the first time in a year and a half, orders for Philips medical imaging equipment edged up in North America. It is the first tangible glimmer of hope that the great imaging recession may finally be over.
MR spectroscopy readies role as cancer diagnosis, treatment tool
The idea of MR spectroscopy has been kicking around almost as long as MR itself. The allure is seductive: a noninvasive biopsy that quantifies in hard numbers the presence-or absence-of cancer.
What's old is new again, and the world rolls on
Recently, there has been some debate in the radiology literature about the demise of general radiology, and with it people like me: general radiologists.
Three decades take MRI from cutting edge to sustainability
Thirty years ago, I counted 12 MRI machines worldwide. Once the total had passed 25,000, I gave up counting.
Mobile image display pioneer blazes regulatory path at FDA
Mobile devices such as the iPhone and newly released iPad are attracting a lot of attention for how they might display medical images.
Dose-saving technologies proliferate throughout CT
The means to reduce radiation dose are often at the fingertips of CT operators.
CT found effective for Dx lung collapse in women
Using high-resolution CT scans to screen for lymphangioleiomyomatosis is cost-effective in women between the ages of 25 and 54 who don’t smoke and come to the emergency room for the first time with a collapsed lung, according to University of Cincinnati researchers.
Abdominal plaque reveals coronary artery disease
Presence of plaque on an abdominal CT scan is a strong predictor of coronary artery disease and mortality, according to a study from Henry Ford Hospital in Detroit.
Modifying technique cuts radiation dose for CTA
Reduced or no “padding” during ECG-triggered coronary CT angiography results in a substantial reduction in radiation dose without affecting image quality and interpretability, according to a study in the April American Journal of Roentgenology.
ACR launches breast MR accreditation program
The ACR has added breast MRI to its repertoire of accreditation programs.
MR finds contralateral breast cancer in elders
MRI detects breast cancer in the contralateral breast for postmenopausal women better than a clinical or mammographic examination, according to a Mayo Clinic study published in the March/April The Breast Journal.
New US technique predicts chemotherapy response
A new ultrasound technique that measures cell death, tumor elastography, and vascular patterns can better predict how well cancer patients are responding to chemotherapy, Canadian researchers report.
CT not yet winning support for lung cancer screening
A study finding relatively high false-positive rates for CT screening of lung cancer will probably not be the definitive word on the subject.
Science, not politics should define imaging dose debate
When it comes to the sizzling hot topic of carcinogenesis and diagnostic radiation, it is crucial to differentiate hypothesis from scientific fact, maintain a sober mind, and separate science from politics and economics.
Modern ultrasound methods yield stronger arthritis work-up
Rheumatoid arthritis is a chronic and progressive inflammatory disease of the joints.
