SPECT/CT using high-resolution CT detector technology has been found to increase the diagnostic capabilities of SPECT when used to detect diseased bone, including osteomyelitis and other peripheral skeletal disease, and at a lower cost than high-resolution multi-detector CT, according to a study published May 23 in the Journal of Nuclear Medicine.

There are several advantages to PET/CT for myocardial perfusion imaging (MPI) including upgrades in quantitative analysis and biomarker technology that could provide a more complete evaluation of cardiovascular disease, according to a review published in the Journal of Nuclear Cardiology.

The U.S. Food and Drug Administration (FDA) has approved Dotarem (gadoterate meglumine) as the first macrocyclic and ionic gadolinium-based contrast agent (GBCA) that can be used in the United States

In a companion piece that counters an opinion that SPECT is the best modality for first-line detection of CAD, separate experts argued that CT finds sub-clinical atherosclerosis and important coronary anatomy, providing earlier diagnoses and the option to be more aggressive with treatment, according to a review published April 10 in the Journal of Nuclear Cardiology.

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
