Diagnosis of acute pulmonary embolism: when photon-counting-detector CT replaces energy-integrating-detector CT in daily routine
ConclusionCompared to EID-CT, morphology and perfusion imaging were available in all patients scanned with PCD-CT, with the radiation dose reduced by 48%.Clinical relevance statementPCD-CT enables scanning patients with the advantages of both spectral imaging, including high-quality morphologic imaging and lung perfusion for all patients, and fast scanning —a combination that is not simultaneously accessible with EID-CT while reducing the radiation dose by almost 50%.

Sociodemographic factors and Child Opportunity Index disparities associated with missed care opportunities in pediatric patients with lymphoma and leukemia referred for FDG-PET/CT
ConclusionChildren with lymphoma/leukemia, living in zip codes with very low or low COI, and who identified as Black/African American non-Hispanic/Latino experienced more MCOs. Our study supports the need to address intersecting sociodemographic, neighborhood, and health system factors that will improve equitable access to necessary healthcare imaging for children.Graphical abstract (Source: Pediatric Radiology)

Ethnic Variation in Lower Face Anthropometry on Facial Computed Tomography Scans for Patients Seeking Facial Feminization Surgery
Facial feminization surgery (FFS) is the most common form of facial gender-affirming surgery. One of the current knowledge gaps is the understanding of racial group differences in baseline craniofacial norms for transgender and nonbinary patients.

Same-day post-therapy imaging with a new generation whole-body digital SPECT/CT in assessing treatment response to [177Lu]Lu-PSMA-617 in metastatic castration-resistant prostate cancer
ConclusionWe successfully implemented same-day post-therapy SPECT/CT after [177Lu]Lu-PSMA-617 infusions. Quantitation of 1 –2 h post-therapy SPECT/CT images is a promising method for assessing treatment response. However, the approach is currently limited by its suboptimal detection of small tumor lesions and the necessity of incorporating a third-cycle SPECT/CT to mitigate the effects of any potential treatment-rela ted flare-up. Further investigation in a larger patient cohort and prospective validation is essential to confirm these findings and to explore the role of SPECT/CT as a potential adjunct to PSMA PET/CT in ...

Validation of ALOS/PALSAR Subsurface Penetration Depth in Farafra Oasis as an Arid Region Based on Field Ground-Penetrating Radar Measurements
AbstractIn the last few years, ALOS/PALSAR (L-band) (HH, HV, VH, and VV) images have been widely used due to their ability to penetrate the surface in certain conditions, such as low moisture or dry friable sandy soil. Images from the ALOS sensor were used to delineate subsurface structures and optical images such as Landsat-7 ETM + data were used to discriminate between scatterings from the Earth’s surface and subsurface materials. Thus, the Farafra Desert is an optimal geological environment for L-band microwave penetration, as its geology is characterized by friable sand sheets covering limestone (Tarawan Formati...

To develop valuable applications for the invasive weed Palmer amaranth, we utilized it as a novel biochar source and explored its potential for methyl orange adsorption through the synthesis of chitosan-encapsulated Palmer amaranth biochar composite microspheres. Firstly, the prepared microspheres were characterized by ...

Molecules, Vol. 29, Pages 1837: Preparation and Anti-Icing Properties of Zirconia Superhydrophobic Coating
min Zhang
Zirconia (ZrO2) is a ceramic material with high-temperature resistance and good insulating properties. Herein, for the first time, the surface of ZrO2 was modified with docosanoic acid (DCA) to improve its self-cleaning and hydrophobic properties. This surface modification transformed the surface of ZrO2 from hydrophilic to superhydrophobic. A two-step spraying method was used to prepare the superhydrophobic surface of ZrO2 by sequentially applying a primer and a topcoat. The primer was a solution configured using an epoxy resin as the adhesive and polyamide as the curing agent, while the topcoat was a modifi...

A New Perspective for Early Detection of Bone Tumour: Metamaterial-Based Antenna Solution
In this study, we designed a non-invasive mathematically supported antenna and tested this antenna on a clinically suitable tibia bone and tumour phantom. The results proved that bone tumour can be detected non-invasively with microwave antennas. (Source: Plasmonics)

Hospital care in the first 10 years of life of children with congenital anomalies in six European countries: data from the EUROlinkCAT cohort linkage study
Conclusions
Children with a congenital anomaly consume a significant proportion of hospital care resources. Priority should be given to public health primary prevention measures to reduce the risk of congenital anomalies. (Source: Archives of Disease in Childhood)

Towards evidence-based medicine for paediatricians
What could it be? It is often the case we would like to know what the chances of different types of diagnosis are, or the chance of a scan finding something or some things with a presentation. These types of questions can be answered in an ‘evidence-based’ way, but they rarely are even thought about let alone addressed. Their appraisal should follow the same model as others; does the paper produce valid findings? Are they meaningful and important? How far is the paper from the population or patient I am thinking of—too far to be helpful? Validity is best gained from an appropriate population, evaluated wi...

Assessment of visual fatigue in SSVEP-based brain-computer interface: a comprehensive study
AbstractFatigue deteriorates the performance of a brain-computer interface (BCI) system; thus, reliable detection of fatigue is the first step to counter this problem. The fatigue evaluated by means of electroencephalographic (EEG) signals has been studied in many research projects, but widely different results have been reported. Moreover, there is scant research when considering the fatigue on steady-state visually evoked potential (SSVEP)-based BCI. Therefore, nowadays, fatigue detection is not a completely solved topic. In the current work, the issues found in the literature that led to the differences in the results a...

Radiographic Outcomes in Paediatric Bronchiectasis and Factors Associated with Reversibility
CONCLUSIONS: This first large cohort confirms bronchiectasis in children is often reversible with appropriate management. Younger aged children and those with lesser radiographic severity at diagnosis were most likely to achieve radiographic reversibility whilst those with PsA infection were least likely.PMID:38631023 | DOI:10.1164/rccm.202402-0411OC (Source: American Journal of Respiratory and Critical Care Medicine)

Metabolic and ultrastructural renal changes in adult Wistar rats fed by a cafeteria diet
CONCLUSIONS: The intake of lipids and simple carbohydrates were found to be associated with alteration in the glomerular ultrastructure. However, more studies are needed to evaluate not only the effects of high-protein and high-fat diets on components of the glomerular filtration barrier, but also renal physiology.PMID:38629653 | PMC:PMC11020636 | DOI:10.1590/acb392224 (Source: Acta Cirurgica Brasileira)
