Comparison of the diagnostic value of virtual touch tissue quantification and virtual touch tissue imaging quantification in infants with biliary atresia.

Objective: This study aimed to compare the diagnostic performance of vital touch tissue quantification (VTQ) and virtual touch tissue imaging quantification (VTIQ) in diagnosing infants with biliary atresia (BA) from jaundiced infants.

Methods: In this study, 26 jaundiced infants with BA, 33 jaundiced infants without BA, and 40 normal infants were enrolled. The hepatic shear wave velocity (SWV) of each infant was determined by VTQ and VTIQ examinations, respectively.

Clinical Application Value of Automated Breast Volume Scanner in the Diagnosis of Abdominal External Hernia.

This study investigated the clinical application value of the automated breast volume scanner (ABVS) in patients with abdominal external hernias. A total of 121 abdominal external hernias from 103 inpatients were examined with both conventional handheld ultrasound (HHUS) and the ABVS before surgery. The rate of detection of abdominal external hernias and the diagnostic accuracy of classifying inguinal hernias using the two modalities were compared between junior and senior sonographers.

Clinical value of serial ultrasonography in the dynamic observation of foetal cystic adrenal lesions.

Objectives: The objective of the study is to evaluate the diagnostic value of ultrasonography in cystic lesions of the adrenal gland.

Methods: Twenty-two cases of adrenal cystic lesions found in the foetal period were retrospectively analysed. All foetuses were followed up by ultrasound after birth, and all lesions were confirmed by operation or ultrasound-guided biopsy.

Prevention of doxorubicin-induced cardiomyopathy using targeted MaFGF mediated by nanoparticles combined with ultrasound-targeted MB destruction.

The present study seeks to observe the preventive effects of doxorubicin-induced cardiomyopathy (DOX-CM) in rats using targeted non-mitogenic acidic fibroblast growth factor (MaFGF) mediated by nanoparticles (NP) combined with ultrasound-targeted MB destruction (UTMD). DOX-CM rats were induced by intraperitoneally injected doxorubicin. Six weeks after intervention, the indices from the transthoracic echocardiography and velocity vector imaging showed that the left ventricular function in the MaFGF-loaded NP (MaFGF-NP) + UTMD group was significantly improved compared with the DOX-CM group.

Improvement of continuous subcutaneous insulin infusion on patients with type 2 diabetes mellitus by 3-dimensional speckle tracking echocardiography.

Three-dimensional speckle tracking echocardiography (3D-STE) was used to evaluate the improvement of continuous subcutaneous insulin infusion on the left ventricular (LV) systolic function of patients with type 2 diabetes mellitu (T2DM). We recruited T2DM patients (38 cases, diabetic group) and healthy volunteers (35 cases, control group) to collect LV full volume imaging. TomTec software was used for calculating LV global longitudinal strain (LVGLS), global circumferential strain (LVGCS), peak twist (LVTW), peak apical rotation (LVPAR), ejection fraction (LVEF), and torsion (LVT).

Biomedical photoacoustics: fundamentals, instrumentation and perspectives on nanomedicine.

Photoacoustic imaging (PAI) is an integrated biomedical imaging modality which combines the advantages of acoustic deep penetration and optical high sensitivity. It can provide functional and structural images with satisfactory resolution and contrast which could provide abundant pathological information for disease-oriented diagnosis. Therefore, it has found vast applications so far and become a powerful tool of precision nanomedicine.
