There may soon be an alternative to FDG-PET in the diagnosis of Alzheimer’s disease (AD) as the non-invasive arterial spin labeling (ASL) MRI method has been shown to provide comparable information, according to a study appearing in
Neurology.

For 22 years,
U.S. News & World Report has issued a report card grading the nation’s hospitals for patient care and acknowledging 50 hospitals as the best. This year, as in years past, Johns Hopkins Hospital, Massachusetts General Hospital and the Mayo Clinic have been chosen as top performers for demonstrating superior care in at least six of the 16 specialties. Cleveland Clinic reclaims its position as number one for heart care for the 17th year in a row.
Researchers discussed the effect that breathing irregularities have on the accuracy of 4D PET scans and outlined a PET imaging method that reduces motion artifacts or image blurring arising from respiratory motion, according to a study presented this week at SNM's 58th annual meeting in San Antonio, Texas. The researchers said that non-gated PET imaging with 4D CT may be useful for imaging patients who do not benefit from the use of respiratory gating, most notably patients with erratic breathing.
A combination of longer scan time (of three minutes) and time-of-flight (TOF) PET imaging provides the “best performance” for imaging large patients or a low-uptake lesion in small or large patients, according to a study in the May issue of the Journal of Nuclear Medicine.

While PET/CT is commonly and very successfully used for the staging and follow-up of cancers, researchers are seeking ways to make the modality more sensitive and specific by using targeted radiotracers and refining scanning techniques.
