Thompson Attempts to study “diffuse modulation” in Br(Coll)2ClO4 have shown that these non-Bragg features disappear very rapidly on exposure to synchrotron radiation, an observation that has implications for those using X-rays as a probe.

CONCLUSION: By using a diverse dataset and comparing the diagnostic accuracy of three imaging modalities commonly used in breast cancer detection and diagnosis, this study also demonstrated that mammography, ultrasonography and MRI had different diagnostic performance in breast tumor identification. Among them, MRI yielded the highest performance even though the unexpected specificity may lead to over-diagnosis, and ultrosonography is slightly better than mammography.

In this study, we focused on the pre-reconstruction space based on the photoelectric and Compton effect decomposition model to characterize different material components, and proposed an efficient method to calculate the projection decomposition coefficient. We converted the complex projection integral into a linear equation by calculating the equivalent monochromatic energy from the high and low energy spectrum. Meanwhile, we constructed a dual-energy CT system based on a photon-counting detector to take small animal scan and material discrimination analysis. Finally, the results of simulation and experimental study demon...

CONCLUSIONS: Determination of the SUV value of the normal pelvis with 99m Tc-MDP SPECT/CT is feasible and highly reproducible. SUVs of the normal pelvis showed a relatively large variability. As a quantitative imaging biomarker, SUVs might require standardization with adequate reference data for the participant to minimize variability. PMID: 30103368 [PubMed - as supplied by publisher]

Radiofrequency ablation (RFA) has been used successfully in Japan to treat post-surgery recurrence of malignant pleural mesothelioma, according to a case study published recently by the Society of Thoracic Surgeons. Although RFA has been utilized for several years to treat various thoracic lesions, the study authors believe this is the first time it worked effectively with mesothelioma cancer cells. “It shows promising efficacy,” the authors wrote. “Radiofrequency should be considered an option for treating recurrence of MPM [malignant pleural mesothelioma].” RFA is a minimally invasive medical proc...

In this study, effects of the synthesised AgNPs were also evaluated on nucellus tissues germination frequency and biochemical parameters of plant tissues. Nucellus tissues of Citrus reticulata were inoculated on MS medium supplemented with 10, 20, 30 and 40 μg/ml suspension of the synthesised AgNPs. Green synthesised AgNPs enhanced the in vitro germination because of low toxicity and nonfriendly issues. Significant results were obtained for germination parameters i.e. root and shoot length and seedling vigour index in response to 30 μg/ml suspension of green synthesised AgNPs. The 30 μ/ml suspension of AgNPs also ...
