Endometrial spatio-temporal image correlation (STIC) and prediction of outcome following assisted reproductive treatment.

Objective: The aim of this study was to correlate manual and spherical endometrial spatio-temporal image correlation (STIC) vascularity indices with assisted reproductive treatment (ART) outcomes.

Study Design: STIC ultrasound assessments of the endometrium were carried out at three time-points in 127 women in a prospective observational study.

Results: Biochemical pregnancy rate was 69% (88/127), with a biochemical and clinical pregnancy loss of 17%.

4-D Assessment of Endometrial Vascularity Using Spatiotemporal Image Correlation: A Study Comparing Spherical Sampling and Whole-Tissue Analysis.

Our aim in the study described here was to assess the feasibility of spatiotemporal image correlation power Doppler quantification of the endometrium with two techniques: spherical samples and whole tissue. We scanned 51 women in the midluteal phase of the menstrual cycle: STIC assessment of the whole endometrium was not possible in 10% of cases, whereas spherical analysis was possible in all. The time taken for data set analysis was much longer for the whole endometrium compared with spherical analysis (1478.

What exactly do we mean by 'recurrent implantation failure'? A systematic review and opinion.

Recurrent implantation failure (RIF) is an iatrogenic condition, being the result of repetitive unsuccessful cycles of IVF or intracytoplasmic sperm injection (ICSI) treatment. The aim of this review was to assess the definitions of RIF used in literature as well as suggest a uniform definition of this condition. A systematic search of MEDLINE, Embase and Cochrane Library was conducted.

Influence of gain adjustment on 3-dimensional power Doppler indices and on spatiotemporal image correlation volumetric pulsatility indices using a flow phantom.

Spatiotemporal image correlation can be used to acquire 3-dimensional power Doppler information across a single cardiac cycle. Assessment and comparison of the systolic and diastolic components of the data sets allow measurement of the recently introduced "volumetric pulsatility index" (vPI) through algorithms comparable with those used in 2-dimensional Doppler waveform analysis. The vPI could potentially overcome the dependency on certain machine settings, such as power, color gain, pulse repetition frequency, and attenuation, since these factors would affect the power Doppler signal equally throughout the cardiac cycle.
