Summary: Acute abdominopelvic pain in pregnant and postpartum patients presents clinical challenges, and quick and accurate imaging diagnosis is required. Ultrasound is the primary imaging investigation, but MRI has shown to be a powerful tool in diagnosing acute abdominal pain during pregnancy and puerperium. This article aims to help radiologists have a thorough understanding of abdominopelvic emergencies in pregnancy and puerperium by illustrating their imaging appearances.

Summary: The study found a high concordance between second-trimester anatomic ultrasound and fetal echocardiography in detecting cardiac abnormalities in pregnancies meeting American Heart Association criteria. However, fetal echocardiography may have higher sensitivity in detecting specific congenital heart defects. Further research on the selective use of fetal echocardiography in at-risk pregnancies is recommended.

Summary: This article develops a dynamic HFUS high-resolution strain imaging technique, successfully obtaining a 2-D high-spatiotemporal dynamic visualization of mouse myocardial strains. The experimental results show that the strains for myocardial infarction (MI) mice are significantly lower than those for wild-type (WT) mice, and there is obvious variation in myocardial strain in the apical anterior region.

Summary: This article introduces an efficient beamformer with sub-Nyquist sampling that is suitable for high-frequency ultrasound imaging. The proposed method reduces computational complexity while maintaining adequate delay resolution through postfiltering-based interpolation and the use of a polyphase structure. Experimental results demonstrate that the proposed method substantially reduces computational complexity without sacrificing spatial resolution for HFUS imaging.

Summary: Chronic kidney disease leads to high morbidity rates among humans, and kidney transplantation is often necessary for severe symptoms. However, due to donor shortage, new curative treatments are desired. Studies have shown that transplantation of the metanephros, ureter, and bladder as a group can efficiently generate urine. Monitoring growth after transplantation using computed tomography and ultrasonography can provide valuable insights for urinary tract reconstruction and potential kidney regeneration in human clinical trials.

Summary: A high-frequency rotary ultrasonic encoder with cylinder gratings was developed to fix NURD and obtain high quality restored image dynamically. The miniature encoder with a diameter of 3 mm and resolutions up to 64 pulses per revolution is demonstrated as the smallest and highest frequency rotary ultrasonic encoder reported, showing great potential for ultrasonic endoscopy, OCT, and other mechanical scanning imaging.

Summary: This study retrospectively analyzed the outcomes of fetuses diagnosed with central nervous system anomalies during the prenatal period. The findings showed that less than 50% of the fetuses resulted in live births, and among the children who survived, 62.79% had neurodevelopmental disabilities by the age of 2.

Summary: Ultrasound imaging commonly uses mechanical or electronic scanning methods. A more affordable and compact solution for high frequency imaging is single-element transducer based ultrasound imaging. In this study, a novel single-element high frequency ultrasound imaging scanner was introduced. The results demonstrate that the scanner allows for high frequency imaging with a scanning speed of up to 208 frames per second, and the image quality was higher than that of electromagnetic motor drive. The ultrasound imaging system is versatile and suitable for various preclinical and clinical applications.

Summary: The study found that 20 kHz and 355 kHz ultrasound had better inactivation efficiency on soy trypsin inhibitors, with increasing ultrasonic power leading to higher inactivation rate constants. For 20 kHz ultrasound, the formation of TI aggregates decreased TI activity, while for 355 kHz ultrasound, oxidation of methionine in TIs accelerated inactivation. Aggregation of TIs further contributed to TI inactivation, with SDS-PAGE showing no involvement of disulphide bonds or C-C coupling in the process.
