1. Niflolidine
Nicotine alpha(4)beta(2) receptor subtypes are implicated in the study of Alzheimer's disease, schizophrenia, substance abuse, lung cancer, and other disorders. We report the development and evaluation of a putative antagonist, 5-(3'-fluoropropyl)-3-(2-(S)-pyrrolidinylmethoxy)pyridine (nifrolidine) as a PET agent for nicotine alpha(4)beta(2) receptors.
J Nucl Med 46:130-40, 2005
2. Whole body MRI
The presented data point toward an increased use of MRI for screening in the future, but to date screening MRI should not be performed outside a research setting because the cost-benefit relation is unclear.
AJR Am J Roentogenol 184:598-611, 2005
3. Screening For Abdominal Aortic Aneurysm
For men age 65 to 75 years, an invitation to attend AAA screening reduces AAA-related mortality (odds ratio, 0.57 [95% CI, 0.45 to 0.74]).
Ann Intern Med 142:203-11, 2005
4. Safety Issue of MRI For Patient with implantable heart device
SAR was limited to 2.0 W/kg for all sequences. Device parameters were assessed immediately post MRI and at chronic follow-up (median 24 days after MRI).
The investigators' new guideline warn that only the newer devices, mainly from the
last seven years, are safe in the scanners and call for low-energy-level scans, avoiding scan settings higher than 2.0W/Kg.
