“Aim: Because of less frequent lymph node metastasis and parametrial involvement, patients

with stage Ib1 cervical cancer may benefit from a curtailment of surgery. We retrospectively investigated the distribution of lymph node metastasis in stage Ib1 patients. After comparing the data with that of higher stages and sentinel lymph node navigation (SLNN), the appropriate extent of lymphadenectomy (LA) in stage Ib1 disease was newly suggested.”
“In this paper, we propose a novel global optimization based 3-D multi-region segmentation algorithm for T1-weighted black-blood carotid magnetic resonance (MR) images. The proposed algorithm partitions a 3-D carotid MR image Rabusertib research buy into three regions: wall, lumen, and background. The algorithm performs such partitioning by simultaneously evolving two coupled 3-D surfaces of carotid artery adventitia boundary (AB) and lumen-intima boundary (LIB) Selleck Proteasome inhibitor while preserving their anatomical inter-surface consistency such that the LIB is always located within the AB. In particular, we show that the proposed algorithm results in a fully time implicit scheme that propagates the two linearly ordered surfaces of the AB and LIB to their globally optimal positions during each discrete time frame by convex relaxation.

In this regard, we introduce the continuous max-flow model and prove its duality/equivalence to the convex relaxed optimization problem with respect to each evolution step. We then propose a fully parallelized continuous max-flow-based algorithm, which can be readily implemented on a GPU to achieve high computational efficiency. Extensive experiments, with four users using 12 3T MR and 26 1.5T MR images, demonstrate that the proposed algorithm yields high accuracy and low operator variability in computing vessel wall volume. In addition, we show the algorithm outperforms previous methods in terms of high computational efficiency and robustness with fewer

user interactions.”
“Carotid-cavernous aneurysm accounts for 29% of all intracranial aneurysms. The rupture of carotid-cavernous aneurysm is usually caused by a trauma. Nevertheless, spontaneous rupture may rarely be encountered. Here, we report a term pregnant woman who was diagnosed to have a spontaneous carotid-cavernous fistula due to carotid-cavernous aneurysm rupture and was managed with detachable Pexidartinib cost balloon and coils immediately after cesarean section.”
“The algorithm proposed in this paper allows to automatically segment the optic disc from a fundus image. The goal is to facilitate the early detection of certain pathologies and to fully automate the process so as to avoid specialist intervention. The method proposed for the extraction of the optic disc contour is mainly based on mathematical morphology along with principal component analysis (PCA). It makes use of different operations such as generalized distance function (GDF), a variant of the watershed transformation, the stochastic watershed, and geodesic transformations.
