Hysterosalpingo-contrast-sonography vs. magnetic resonance-hysterosalpingography for diagnosing fallopian tubal patency: A systematic review and meta-analysis

Hysterosalpingo-contrast-sonography vs. magnetic resonance-hysterosalpingography for diagnosing fallopian tubal patency: A systematic review and meta-analysis

February 12, 2020 — European Journal of Radiology
Abstract
Purpose
To compare hysterosalpingo-contrast-sonography (HyCoSy) and magnetic resonance-hysterosalpingography (MR-HSG) in the diagnosis of fallopian tubal patency.
Materials and methods
The databases of PubMed, Embase, and the Cochrane Library were searched for records up to November 30, 2019. Studies involved in the diagnostic detection of HyCoSy or MR-HSG for fallopian tubal patency using conventional HSG or laparoscopy as the reference test were included. Data was analyzed by meta-analysis. We compared sensitivity, specificity, positive and negative likelihood ratios (read more…)

Lantheus touts new study on contrast echocardiography

February 4, 2020 — AuntMinnie.com
By AuntMinnie.com staff writers
Lantheus Medical Imaging parent company Lantheus Holdings announced the results of its Benefit 1 clinical trial, which evaluated the potential advantages of using its Definity ultrasound contrast agent to evaluate heart failure.
The trial results indicated that contrast-enhanced echocardiography led to statistically significant improvements in measurements of left ventricular diastolic and systolic blood flow as well as stroke volume for the 145 trial participants, compared with unenhanced echocardiography and cardiac MRI.
However, contrast-enhanced (read more…)

DOI https://doi.org/10.2147/IJN.S201208
Abstract:
Ultrasound-mediated targeted delivery (UMTD), a novel delivery modality of therapeutic materials based on ultrasound, shows great potential in biomedical applications. By coupling ultrasound contrast agents with therapeutic materials, UMTD combines the advantages of ultrasound imaging and carrier, which benefit deep tissue penetration and high concentration aggregation.
