Growth in cancer patients’ radiation exposure exceeds that of general population

Shift to ultrasound for appendicitis could reap $21.8 million annual savings
U.S. hospitals could save nearly $22 million annually by deemphasizing CT in favor of diagnostic ultrasound as the frontline imaging test for suspected appendicitis. Such a change would also spare many patients unnecessary exposure to ionizing radiation from CT, according to financial evaluation and meta-analysis by Laurence Parker, Ph.D., an imaging economics researcher at Thomas Jefferson University in Philadelphia.

Dr. Hedvig Hricak used her presidential address before the opening session of the 2010 RSNA meeting to express her desire for a new molecular imaging subspecialty while cautioning radiologists that MI is not appropriate for all clinical settings.
MRI reveals brain damage in retired athletes
A growing body of data is linking sportsrelated concussions to brain damage associated with cognitive impairment.

In the aftermath of CT-related radiation accidents at the prestigious Cedars-Sinai Medical Center in Los Angeles, the FDA, healthcare providers, and manufacturers are taking action to avoid suffering through similar situations themselves.
Outpatient imaging audit uncovers quality wasteland
An in-depth look at outpatient imaging services in Southeast Michigan has uncovered a wasteland of outpatient imaging where technologists are poorly trained, imaging is interpreted without written records, and films are allowed to pile up in patient waiting rooms.
Iterative reconstruction slashes radiation levels
CT vendors have responded to public concerns about radiation dose with innovations that promise to cut patient exposure substantially without affecting imaging service operations.
MRI reveals sport-related brain damage
The brains of 24 retired National Football League players with known cognitive impairment show signs of damaging atrophy, according to advanced MRI studies described at the 2009 RSNA annual meeting.
Disaster survivors show early signs of traumatic stress
An international research team has established the Wenchuan earthquake on May 12, 2008, exacted a toll beyond the nearly 70,000 deaths and 374,000 casualties from the magnitude 8.0 temblor.
Coronary calcium scoring can be trusted to guide cardiac test selection
Coronary artery calcium scanning predicts the risk of myocardial infarction and sudden death accurately enough to guide the selection of diagnostic tests for symptomatic patients, according to a multicenter prospective study.
Cardiologists boost imaging to compensate for lower DRA-related rates
The ability to self-refer may explain why cardiologists were better able than radiologists to adjust to Medicare rate cuts after the implementation of reimbursement reforms from the federal Deficit Reduction Act of 2005.
Berger urges imagers to be stewards of radiology
Dr. Paul E. Berger, founder and former board chair of NightHawk Radiology, a $168 million teleradiology firm, is advising fellow radiologists to again emphasize their role as stewards of medical imaging to guard against the teleradiology revolution he helped foment.
Using functional MRI, an international research team has established the Wenchuan earthquake on May 12, 2008, exacted a toll beyond the nearly 70,000 deaths and 374,000 casualties from the magnitude 8.0 temblor.
Senate OKs mammo mandate; preventive services chief says message was distorted
The controversy surrounding mammography screening guidelines announced in November by the influential U.S. Preventive Health Services Task Force has continued to swirl in the nation’s capital.
Multigland parathyroidism reduces accuracy of lesion detection
Standard nuclear scintigraphy of parathyroid cancer produces enough false positives for patients with multigland disease to lead researchers to recommend rapid intraoperative parathyroid hormone assay along with preoperative technetium-99m sestamibi imaging to assure that all lesions have been removed.
Radiologist lose piece of the radioisotope pie
Endocrinologists are biting into radiology’s control over the management of nuclear imaging procedures involving an administration of radioiodine.
Advanced MRI reveals damage in brains of retired NFL football players
The brains of 16 retired National Football League players with known cognitive impairment show signs of damaging atrophy, according to advanced MRI studies described Wednesday at the 2009 RSNA annual meeting.
CTA shows promise for myocardial perfusion imaging
A preliminary study suggests that CTA can play the role cardiac MRI has been playing for detecting and quantifying myocardial infarction to estimate the potential success of coronary bypass graft surgery.
Iterative reconstruction cuts radiation up to 90% during coronary CTA
CT vendors have been talking for months about the potential of iterative reconstruction as the next big thing to substantially reduce the worrisome radiation dose patients are exposed to during multislice CT imaging. Now they have results of a large multicenter cohort study to add substance to their enthusiasm.
Manganese liver contrast medium may help to cut imaging times
CMC-001, an investigational MRI liver contrast medium, may be at least a partial answer to reducing the long imaging times that have frustrated patients and encouraged radiologists to look for imaging alternatives to aid diagnosis of hepatocellular carcinoma and colon cancer metastases in the liver. A phase III trial indicates it is as sensitive as a gadolinium-enhanced MRI for detecting colon cancer metastases, but at the cost of lower specificity.
Case review finds 31% error rate among local imaging services
Radiologist Dr. Richard M. Chesbrough has taken an in-depth look at outpatient imaging services in Southeast Michigan, and the resulting picture is not pretty
