Studies link Alzheimer's to beta-amyloid and potential for new ligand
By Wayne Forrest
Two studies by Australian researchers are shedding light on Alzheimer's disease. The first looked at the cause of the debilitating condition and the connection between the presence of the toxic brain protein beta-amyloid and Alzheimer's. The other study examined the potential of a new biomarker for disease detection, offering the first results from human studies of the F-18 PET ligand for brain beta-amyloid imaging.

Automated analysis tools vary in pulmonary nodule measurements
By Erik L. Ridley
Different automated analysis tools vary in determining the size of pulmonary nodules, according to a multi-institutional research group. With data from a lung nodule detection study, the researchers used commercially available automated analysis packages to quantify the variations in nodule maximum diameter and volume among the different software tools. They found maximum dimension is an unreliable marker of tumor size, even when using automated analysis software.

Correlating symptoms with lumbar spine MR: Challenges to the radiologist and referring clinician
Degenerative and herniated disks may lead to potentially disabling disorders and greatly reduce the quality of life of a significant proportion of the population. For the referring clinician, MRI can differentiate between normal age-related disk changes and pathological disks. Chiropractor Dr. Gerald Anzalone offers a primer on disk morphology, as well as some tips for imaging professionals on the information clinicians hope to gain from an MR exam.

The parallax view: Digital breast tomosynthesis has cancer screening in its crosshairs
By Sydney Schuster
Built on full-field digital mammography (FFDM) technology, digital breast tomosynthesis (DBT) combines 2D image slices to form a 3D composite exam. Trials indicate DBT images are superior to both FFDM and film-screen mammography in terms of quality and acquisition time. Early talk is that DBT not only will find breast cancers earlier, but also fix mammography's liability woes and restore its tarnished popularity among imaging specialists.

Patient survey suggests preference for minimal-prep VC
By Eric Barnes
While colorectal cancer is the second leading cause of death in the U.S., less than half of screening age individuals over 50 are examined for the disease. A new survey suggests that eliminating the cathartic bowel preparation might improve compliance screening rates. But the answers may not predict patients' real interest in screening, and the minimal-prep approach is not without complications, cautioned a radiologist experienced in virtual colonoscopy screening.
