Marijuana increases lung cancer risk
By
Eric Barnes
Despite the biological plausibility of marijuana being carcinogenic, and suggestions that overall lung cancer risk may be associated with pot smoking, epidemiologic findings of marijuana use have been weaker and far less consistent than studies associating tobacco smoking with lung cancer. But a new study from New Zealand finds that pot smokers do indeed face higher lung cancer rates that increase for every year of smoking, and for patients who begin smoking younger.

Radiology still has a chance to control cardiac CT
By
Cynthia E. Keen
In the decades-long struggle between radiologists and cardiologists over control of new cardiac imaging technologies, the heart specialists have an undefeated record.

VC measurements more accurate than optical colonoscopy
By
Eric Barnes
Virtual colonoscopy did a better job of measuring polyps than optical colonoscopy, and optimized 2D measurements were slightly more accurate than 3D, according to a just-published study from South Korea. The measurements affect not only thresholds for removal, but also polyp-matching algorithms in both modalities, explained the researchers from the Asan Medical Center and Seoul National University Hospital in Seoul.

Axial-loaded imaging of lumbar spine heightens diagnostic accuracy
MRI and CT allow clinicians to obtain sensitive 3D images of the spine, intervertebral disks, and neural structures, but both modalities have limitations when it comes to dynamic stress studies. Dr. Gerald Anzalone, a New York-based chiropractor, discusses how axial-loaded imaging can ramp up diagnostic specificity and enhance the visualization of dynamic spinal responses to compressive forces.
