Detecting and accurately identifying malignant lung nodules in chest CT scans in a timely manner is crucial for effective lung cancer treatment. This study introduces a deep learning model featuring a multi-channel attention mechanism, specifically designed for the precise diagnosis of malignant lung nodules. To start, we standardized the voxel size of CT images and generated three RGB images of varying scales for each lung nodule, viewed from three different angles.

Background: Currently, most researchers mainly analyzed coronavirus disease 2019 (COVID-19) pneumonia visually or qualitatively, probably somewhat time-consuming and not precise enough.

Purpose: This study aimed to excavate more information, such as differences in distribution, density, and severity of pneumonia lesions between males and females in a specific age group using artificial intelligence (AI)-based computed tomography (CT) metrics. Besides, these metrics were incorporated into a clinical regression model to predict the short-term outcome.

Background: The efficacy of ethiodized poppyseed oil in hysterosalpingography (HSG) image quality and fertility enhancement has been revealed, but whether this HSG modality has similar effects in the Chinese population is still unclear.

Methods: Between July 18, 2017, and December 29, 2019, this multicentric, randomized, two-arm, clinical trial was performed involving 15 medical centers. Infertile women meeting HSG indications were randomly assigned to an oil group and a water group.

Purpose: To investigate the clinico-radiological findings and outcomes in pregnant women with COVID-19 pneumonia compared to age-matched non-pregnant women.

Methods: A retrospective case-controlled study was conducted to review clinical and CT data of 21 pregnant and 19 age-matched non-pregnant women with COVID-19 pneumonia. Four stages of CT images were analyzed and compared based on the time interval from symptom onset: stage 1 (0-6 days), stage 2 (7-9 days), stage 3 (10-16 days), and stage 4 (>16 days).

The current outbreak of coronavirus disease 2019 (COVID-19) has been defined as a pandemic by the World Health Organization. We aimed to evaluate the clinical features and virological course of non-severe COVID-19 patients with or without symptoms who were admitted to a Chinese cabin hospital. In this retrospective single center study, we reviewed 252 laboratory-confirmed COVID-19 patients treated at one temporary cabin hospital in Wuhan, China.

Background: The ongoing outbreak of COVID-19 pneumonia is globally concerning. We aimed to investigate the clinical and CT features in the pregnant women and children with this disease, which have not been well reported.

Methods: Clinical and CT data of 59 patients with COVID-19 from January 27 to February 14, 2020 were retrospectively reviewed, including 14 laboratory-confirmed non-pregnant adults, 16 laboratory-confirmed and 25 clinically-diagnosed pregnant women, and 4 laboratory-confirmed children.

Article Synopsis
  • The study aimed to see how different types of monitoring affect complications after a surgery for women with cesarean scar pregnancy.
  • It involved 144 women who were split into three groups: one with hysteroscopy monitoring, another with ultrasonography monitoring, and a third with no monitoring.
  • Results showed that the group with no monitoring had the highest complications (12), while hysteroscopy monitoring had the fewest complications (1), suggesting monitoring helps reduce risks.

Aim: The aim of this study was to respectively evaluate the feasibility and safety of bilateral uterine artery chemoembolization (UACE) combined with dilation and curettage (D&C) for the treatment of cesarean scar pregnancy (CSP).

Material And Methods: Our study was approved by our institutional review board, with informed patient consent. From January 2004 to December 2010, 79 patients with CSP underwent UACE in our institution, with transcatheter infusion of 30-50 mg methotrexate into the bilateral uterine artery before embolization with sponge particles.
