Understanding the Current Status of Nuclear Cardiology
نویسنده
چکیده
The recent publication by Shaw, et al, (1) regarding the present status and future prospects for myocardial perfusion imaging (MPI) fails to explore one of the most important facts essential to understanding this issue and this commentary fails to fully address the fundamental inadequacy of MPI as a first line diagnostic screening tool for CAD. Figure 2 of this article clearly presents the specificity for detection of CAD by standard rotational SPECT MPI to be 74%. This value has been previously corroborated by De Prez, et al (2) in a literature review commissioned by ASNC and published in the Journal of Nuclear Cardiology (JNC). The De Prez report examined the cost-effectiveness of MPI and stated that “1 in 4 of the normal patients undergoing MPI for detection of CAD is likely to have a falsely abnormal finding”. This reality has influenced all parties concerned about the clinical efficacy of MPI, including third-party payers, to critically scrutinize the degree to which MPI is being utilized for clinical diagnosis and calls into question its cost-effectiveness. Shaw, et al, fail to explore this issue.

The current status and future of theranostic Copper-64 radiopharmaceuticals
Copper-64 was produced in large scales and high specific activities in late 1990s’ using compact cyclotrons based by 64Ni(p,n)64Cu reaction and many radiopharmaceuticals developed since then by various groups based on interesting physicochemical and nuclear properties of the radionuclide. The unique emission of beta particles as well as positron particles offers a spectacu...
متن کاملNuclear cardiology in China: 2017
This paper provides the current state of nuclear cardiology in China and contrasts it with the state of nuclear cardiology in the United States (US). The West China Hospital and New York-Presbyterian Hospital (NYPH) were used as representative hospitals to contrast nuclear cardiology in China and the US, respectively. In 2015, there were 101 medical cyclotrons, 774 SPECT or SPECT/CT, 240 PET/CT...

In this review, we discuss the use of a variety of 3-D models (particularly 3-D skin, lung, breast and endothelial) in radiobiological research and highlight the differences in responses compared to 2-D culturing conditions (monolayers). We review the characteristics of existing 3-D models and aim to point out the substantial advantages 3-D cultures provide for modern radiobiology. In particula...
