Aim: The aim of this meta-analysis is to evaluate the diagnostic accuracy of three-dimensional transvaginal ultrasound subjective assessment (3D-TVS) in the preoperative detection of deep myometrial invasion (MI) in patients with endometrial cancer, using definitive frozen section diagnosis after surgery as the reference standard. Material and methods: A search for studies evaluating the role of 3D-TVS for assessing myometrial invasion in endometrial cancer from January 1990 to Novem-ber 2020 was performed in PubMed/MEDLINE and Web of Science. The Quality Assessment of Diagnostic Accuracy Studies 2 evaluated the quality of the studies (QUADAS-2). All analyses were performed using MIDAS and METANDI commands. Results: Nine studies comprising 581 women were included. The mean prevalence of deep MI was 39.8%. QUADAS as-sessment showed that most studies had a high risk for the patient selection domain. Overall, the pooled estimated sensitivity, specificity, positive likelihood and negative likelihood ratio of 3D-TVS for detecting deep MI were 84% (95% CI, 73-90%), 82% (95% CI, 75-88%), 5 (95% CI, 3.1-7.1) and 0.20 95% CI, 0.11-0.35). respectively. Conclusions: 3D-TVS has an accept-able diagnostic performance for detecting MI in women with endometrial cancer.

The goal of this study was to compare the sonographic assessment of endometrial cancer diagnosis and staging using three-dimensional transvaginal sonography with the staging that was ultimately found at surgery. Three-dimensional transvaginal sonography was performed for 20 consecutive cases of presumptive endometrial cancer using power Doppler angiography, virtual organ computer-aided analysis, and volume contrast imaging. These results were compared with the surgical staging found for those identified cases. The sonographic findings predicted the correct minimum endometrial cancer staging in 100% of the 20 cases that were examined and correlated to surgical outcomes. The successful prediction of endometrial cancer staging demonstrated by others was replicated in the organization of this case series. The findings compared favorably with other imaging modalities used for this purpose. This study assists in demonstrating the value of using presurgical three-dimensional sonography to plan for the optimal surgical excision and overall treatment of endometrial cancer.

The supply of oxygen in sufficient quantity is vital for the correct functioning of all organs in the human body, especially for skeletal muscle during exercise. Traditionally, microvascular oxygen supply capability is assessed by the analysis of morphological measures on transverse cross-sections of muscle, e.g. capillary density or capillary-to-fibre ratio. In this work, we investigate the relationship between microvascular structure and muscle tissue oxygenation in mice. Phase contrast imaging was performed using synchrotron radiation computed tomography (SR CT) to visualize red blood cells (RBCs) within the microvasculature in mouse soleus muscle. Image-based mathematical modelling of the oxygen diffusion from the RBCs into the muscle tissue was subsequently performed, as well as a morphometric analysis of the microvasculature. The mean tissue oxygenation was then compared with the morphological measures of the microvasculature. RBC volume fraction and spacing (mean distance of any point in tissue to the closest RBC) emerged as the best predictors for muscle tissue oxygenation, followed by length density (summed RBC length over muscle volume). The two-dimensional measures of capillary density and capillary-to-fibre ratio ranked last. We, therefore, conclude that, in order to assess the states of health of muscle tissue, it is advisable to rely on three-dimensional morphological measures rather than on the traditional two-dimensional measures.
