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.

A population-based cohort study revealed cancer incidence was 24 percent greater in people who underwent CT imaging at least one year prior to diagnosis, according to research published online May 22 in BMJ. The researchers called for increased awareness of the risks and benefits of CT imaging among providers and increased utilization of decision tools.

In a first-of-its-kind procedure, a biomaterial splint crafted using a combination of CT imaging and 3D printing was used to repair an infant’s airway and save the baby’s life. The case was described in published correspondence May 23 in the New England Journal of Medicine.

Researchers have developed and are testing a urine test that measures the presence of pteredines, a biomarker for cancer. Abnormally high concentrations may indicate cancer. Read more at the link below.

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.
