The article "Amyvid makers call for CMS coverage of amyloid imaging," has been revised.

Some clinicians maintain that cardiac-computed tomography angiography (CCTA) bests SPECT/CT for the detection of CAD, but two expert nuclear cardiologists suggest the opposite and presented data to demonstrate their case, in a study published April 10 in the Journal of Nuclear Cardiology.

The use of algorithms is changing the game for close-as-possible assessment of tumor volume and resolution recovery from PET cancer imaging, especially small objects affected by partial volume effects. Researchers conducting phantom studies have optimized quantitative tumor delineation of F-18 FDG PET imaging with two specialized algorithms that provide accurate partial volume correction for volumes as small as one-third of a milliliter, according to research published May 8 in the Journal of Nuclear Medicine.

The FDA has granted 510(k) clearance to Varian Medical Systems Nexus DRF Digital X-Ray Imaging System. The new diagnostic X-ray image processing workstation combines radiography/fluoroscopy (RF) and digital radiography (DR) capabilities on one platform

Addressing the need for better imaging of tissue surrounding metal-containing implants such as joint replacements, GE Healthcare and researchers at the Hospital for Special Surgery in Waukesha, Wis., designed and tested a novel MR imaging technique that cuts down on the image distortion caused by metal in implants

I have been struggling recently with the notion that genomics is going to revolutionize our ability to diagnose and treat disease. Why? A basic tenet of information theory is simple: the more precisely you can measure something, the less information it contains.

Intraoperative lymphatic mapping provides surgeons, oncologists and referring physicians with vital information about potential malignancy in the lymphatic system, especially that of sentinel lymph nodes—usually the first check point for the diasporas of metastatic cancer cells that drain from primary tumors. Patients have a better chance of avoiding the increased morbidity associated with extensive nodal dissection by undergoing a biopsy of the sentinel lymph nodes most likely to contain metastatic disease.

Prostate cancer patients with advanced tumors that have spread to bone have a poor prognosis; men with castrate-resistant prostate cancer generally live three to five years after diagnosis.
