Missed lesions offer lessons in VC
Even when an experience is less than optimal, it can still be a great teacher. In the case of a recent multicenter VC trial that yielded disappointing results, radiologists took the time to learn where, how, and why lesions were missed.

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.

Gonadal shield cuts scatter radiation from MDCT
Organs with rapidly dividing cell systems, such as the gonads, are more sensitive to radiation than other body regions. But the rise of multidetector-row CT saw the abandonment of gonadal shielding because the x-ray source was considered difficult to shield against. Researchers from Germany, however, have found that gonadal protection is effective and easy to provide.

Detecting analgesic nephropathy a pain on CT
The recent news about problems associated with painkillers based on COX-2 inhibitors has left many patients scrambling for over-the-counter analgesics. But analgesic overuse can lead to nephropathy and end-stage renal disease, and unfortunately, a new study finds that noncontrast CT may be a poor method of detecting the effects of overuse.

VC CAD system finds polyps in opacified fluid
Researchers from the National Institutes of Health have tweaked their colon CAD algorithm to detect polyps submerged, or partly submerged, in opacified fluid. The study represents another key step in the rapid evolution of colon CAD, paving the way for automated polyp detection with the use of oral contrast agents.

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.

Early arterial phase best for HCC detection
Early arterial-phase imaging may be optimal for detecting hepatocellular carcinoma with CT, but once the lesion is found you'll want to add a few seconds' delay to assess tumor hemodynamics, according to a presentation at the RSNA meeting in Chicago earlier this month.

Low-prep VC study finds CAD can be fooled
Computer-aided detection found most of the polyps in a reduced-prep virtual colonoscopy protocol, a new study concludes. On the other hand, the technique produced too many false-positives when barium fecal tagging was incomplete, which was often.

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.
