Microscopic image segmentation (MIS) is a fundamental task in medical imaging and biological research, essential for precise analysis of cellular structures tissues. Despite its importance, the process encounters significant challenges, including variability conditions, complex structures, artefacts (e.g., noise), which can compromise accuracy traditional methods. The emergence deep learning (DL) has catalyzed substantial advancements addressing these issues. This systematic literature review (SLR) provides comprehensive overview state-of-the-art DL methods developed over past six years microscopic images. We critically analyze key contributions, emphasizing how specifically tackle challenges cell, nucleus, tissue segmentation. Additionally, we evaluate datasets performance metrics employed studies. By synthesizing current identifying gaps existing approaches, this not only highlights transformative potential enhancing diagnostic research efficiency but also suggests directions future research. findings study have implications improving methodologies applications, ultimately fostering better patient outcomes advancing scientific understanding.

To promote further development of medical image segmentation, there is an increasing demand for high-quality datasets. Regrettably, are two major obstacles which the difficulty acquiring available images and financial burden data annotation constructing overcome difficulties, we leverage text to compensate defects existing In this work, propose a dual U-shaped network sufficiently achieve cross-modal feature fusion text. Specifically, one branches based on convolution neural network, named U-CNN, mainly extracts global features generate final prediction results. The other vision transformer blocks, U-ViT, responsible processing information merging from U-CNN. Additionally, utilize Cross-Attention Channel Fusion module Channel-wise Dual-branch Cross equip skip connection And modules greatly beneficial resolving semantic gaps enhancing integration information. Experimental results lung infection datasets with different modalities (X-Ray CT) suggest our method achieves excellent performance compared alternative state-of-the-art methods.

Objectives The purpose of this study was to construct a nomogram identify patients at high risk gastric precancerous lesions (GPLs). This identification will facilitate early diagnosis and treatment ultimately reduce the incidence mortality cancer. Methods In single-center retrospective cohort study, 563 participants were divided into lesion (GPL) group (n=322) non-atrophic gastritis (NAG) (n=241) based on gastroscopy pathology results. Laboratory data demographic collected. A derivation (n=395) used factors associated with GPLs develop predictive model. Then, internal validation performed (n=168). We area under receiver operating characteristic curve (AUC) determine discriminative ability model; we constructed calibration plot evaluate accuracy decision analysis (DCA) assess clinical practicability Results Four –predictors (i.e., age, body mass index, smoking status, –triglycerides) included in AUC values model 0.715 (95% CI: 0.665-0.765) 0.717 0.640-0.795) cohorts, respectively. These indicated that had good discrimination ability. plots DCA suggested net benefit. Hosmer–Lemeshow test results cohorts for 0.774 0.468, Conclusion herein demonstrated performance terms predicting GPLs. can be beneficial detection GPLs, thus facilitating reducing
