New guidelines for resuscitating children recommended
By
Cynthia E. Keen
Two new clinical studies used CT to determine that European guidelines for setting the depth of chest compression when resuscitating children may be more accurate than those followed in the U.S. The U.S. guidelines actually could lead to injury in children, researchers say.

High-pitch cardiothoracic CTA skips breath-holds and high doses
By
Eric Barnes
A new way to use CT angiography (CTA) to scan fast-moving targets -- such as fidgety children and grown-ups with rapid heartbeats -- is becoming routine at a hospital in France.

PET/CT improves preoperative staging of non-small cell lung cancer
By
Reuters Health
NEW YORK (Reuters Health), Jul 2 - Combined positron-emission tomography and computed tomography (PET/CT) improves the staging of non-small cell lung cancer and also reduces the numbers of total and futile thoracotomies, Danish researchers report in the July 2

FDG-PET/CT predicts radiation-induced lung toxicity
By
AuntMinnieEurope.com staff writers
FDG-PET/CT exams may be able to identify lung cancer patients who are highly susceptible to developing radiation-induced lung toxicity early during radiation therapy, according to researchers at the Maastricht University Medical Center in the Netherlands.

CARS report: New CAD tool follows lung nodules over time
By
Eric Barnes
BERLIN - It's easy to complain about the insanity of tracking lung nodule changes in multiple CT scans over time, but at least one group is doing something about it, according to a presentation at the Computer Assisted Radiology and Surgery (CARS) meeting.

Dose can be reduced by 75% in pediatric chest CT exams
By
Cynthia E. Keen
The radiation dose of pediatric MDCT exams can be reduced by as much as 75% without compromising the ability to detect small lung nodules in young children, according to a study published in the July issue of

Stereotactic body radiation slows lung cancer
By
Reuters Health
NEW YORK (Reuters Health), May 22 - Stereotactic body radiation therapy appears to be highly effective for treating certain patients with non-small cell lung cancer, providing a three-year local tumor control rate of 90% or higher with minor toxicity, Scandinavian researchers report in a May 4 online edition of the

CT screening has little effect on smoking habits
By
Reuters Health
NEW YORK (Reuters Health), May 22 - The results of a study published in the May issue of
Thorax
suggest that CT screening has little effect on the smoking habits of patients at one-year follow-up compared with smokers who do not undergo screening. CT screening neither induces more smoking nor promotes cessation, the researchers conclude.

Audio and visual aids decrease radiation therapy treatment times
By
Cynthia E. Keen
Use of respiratory-gating techniques during free breathing reduces healthy tissue exposure to radiation, but has the drawback of longer radiation therapy delivery times. Belgian researchers may have found a solution in an inexpensive, low-tech technique: At their center, visually guided voluntary breath-hold along with audio assistance reduced treatment time duration so that it's comparable to conventional treatment times.

Two lung CAD systems unaffected by low dose
By
Eric Barnes
A face-off between two lung nodule computer-aided detection (CAD) systems found a big difference in sensitivity for detecting solid pulmonary nodules, but it also revealed the good news that nodule detection was unaffected by low-dose scanning. The number of false positives also differed significantly between the two systems, researchers from Germany reported.

Cancer cure rates on the rise in Europe: study
By
Reuters Health
LONDON (Reuters), Mar 24 - More Europeans are beating cancer, perhaps due to more widespread screening and earlier diagnosis, according to a study published on Tuesday.

NELSON lung cancer trial yields positive early results
By
Eric Barnes
VIENNA - A first peek at the first results of the first large randomized lung cancer screening trial to near completion found that CT detected four-fifths of participants' lung cancers at stage I -- in time to effect a curative resection.
