RF ablation gains ground as lung cancer option

CT-guided radiofrequency ablation of lung tumors produced outstanding results in patients with inoperable stage 1A non-small cell lung cancer, according to Italian researchers. However, another group from Los Angeles reports that more research is needed to determine whether RFA will fulfill its early promise as the sole treatment for inoperable lung cancer.

CAD substantially improves MDCT's sensitivity in detecting lung nodules

By Tracie L. Thompson

With multidetector computed tomography (MDCT), radiologists can identify more lung nodules than they could with earlier technology. But with MDCT's increased resolution comes numerous image datasets. However, CAD systems can help radiologists work through the images, and new research confirms that the systems do a better job than a second radiologist in detecting missed nodules.

MDCT detects PE incidentally

Unsuspected pulmonary embolism is more common than previously reported, according to researchers from Italy, who found a high prevalence of incidentally detected PE using thin-slice multidetector-row CT. Fortunately, the group also reported in a later study, preclinical probability can be a fairly reliable pretest indicator of PE risk.

Study compares eight digital x-ray systems in clinical setting

By Tracie L. Thompson

Over a relatively brief time period, the medical imaging industry has seen the development of a number of different x-ray systems with varying approaches to x-ray detection. But do differences in detector technology equate to differences in diagnostic performance? The latest answer from one group of Dutch researchers appears to be a qualified yes.

Ultralow-dose CT lung scan shows high accuracy at chest film dose

European researchers have been known to take low-dose CT exams to new levels of low, but a new study from Germany tests even continental norms. When researchers at Berlin's Charité Hospital cranked their thoracic CT exam down to the level of a two-view chest x-ray, they found the technique performed nearly as well as a standard CT exam in detecting pulmonary nodules.

PET/CT hardware hybrid tops PET, software fusion for NSCLC staging

By Jonathan S. Batchelor

Hardware-integrated PET/CT provides greater staging accuracy for non-small cell lung cancer (NSCLC) than either standalone PET imaging or software fusion of PET and CT images from nonintegrated modalities, according to research presented at the RSNA meeting in Chicago last week.

Lung cancer screening spots lesions early, gives patients additional longevity

By Edward Susman

CT-based lung cancer screening can find the disease early enough to improve survival rates, especially in those patients who elect to have immediate surgery, according to the latest results from the International Early Lung Cancer Action Project (I-ELCAP).

Ultrasound beats CT as second choice for pediatric chest disorders

By N. Shivapriya

CHICAGO - There is more evidence for the use of ultrasound instead of CT, with its dangers of ionizing radiation, for chest disorders in children. For many cases in which plain film is insufficient, ultrasound can be the second modality of choice instead of CT, according to research from the Rambam Medical Center in Israel.
