Article Abstract
Objective: To correlate fetal brain magnetic resonance imaging (MRI) findings with epilepsy characteristics and neurodevelopment at 2 years of age in children with tuberous sclerosis complex (TSC) to improve prenatal counseling.
Study Design: This retrospective cohort study was performed in a collaboration between centers of the EPISTOP consortium. We included children with definite TSC, fetal MRIs, and available follow-up data at 2 years of age. A pediatric neuroradiologist masked to the patient's clinical characteristics evaluated all fetal MRIs. MRIs were categorized for each of the 10 brain lobes as score 0: no (sub)cortical lesions or doubt; score 1: a single small lesion; score 2: more than one small lesion or at least one large lesion (>5 mm). Neurologic manifestations were correlated to lesion sum scores.
Results: Forty-one children were included. Median gestational age at MRI was 33.3 weeks; (sub)cortical lesions were detected in 97.6%. Mean lesion sum score was 4.5. At 2 years, 58.5% of patients had epilepsy and 22% had drug-resistant epilepsy. Cognitive, language, and motor development were delayed in 38%, 81%, and 50% of patients, respectively. Autism spectrum disorder (ASD) was diagnosed in 20.5%. Fetal MRI lesion sum scores were significantly associated with cognitive and motor development, and with ASD diagnosis, but not with epilepsy characteristics.
Conclusions: Fetal cerebral lesion scores correlate with neurodevelopment and ASD at 2 years in children with TSC.

Right hemisphere language network plasticity in aphasia.

The role of the right hemisphere in aphasia recovery has been controversial since the 19th century. Imaging studies have sometimes found increased activation in right hemisphere regions homotopic to canonical left hemisphere language regions, but these results have been questioned due to small sample sizes, unreliable imaging tasks, and task performance confounds that affect right hemisphere activation levels even in neurologically healthy adults. Several principles of right hemisphere language recruitment in aphasia have been proposed based on these studies: that the right hemisphere is recruited primarily by individuals with severe left hemisphere damage, that transcallosal disinhibition results in recruitment of right hemisphere regions homotopic to the lesion, and that increased right hemisphere activation diminishes to baseline levels over time.

Spasticity results from upper motor neuron lesions and can create a deforming force, pain, and is often accompanied by contracture. While the origin of spasticity is neural, there is ample evidence of secondary muscle changes. Here we use direct measurement of the force-frequency relationship (FFR) to characterize human muscle's physiological properties.

Their incidence increases with increase in age, especially in individuals suffering from chronic disorders like diabetes. The process of wound healing consists of a series of coordinated biological events triggered by tissue damage, ultimately leading to the repair and restoration of damaged tissues.

By comparing the relevant image manifestations and diagnostic results of high resolution CT (HRCT) and digital radio graphy (DR), to deeply explore the clinical application value of HRCT in the diagnosis and staging of occupational pneumoconiosis. A total of 180 pneumoconiosis patients with different stages diagnosed in Guangzhou Twelfth People's Hospital from January 2022 to May 2023 were selected as the research objects by systematic sampling method, and their HRCT and DR examinations were performed. The display of lung imaging features of patients with pneumoconiosis by the two examination methods was analyzed, and the chi-square test and rank sum test were used to compare the differences in diagnostic staging results and the detection of pulmonary complications.

Background: Intraoperative intraperitoneal chemotherapy using sustained-release fluorouracil implants has been used to reduce the recurrence of gastrointestinal tumors. However, these implants may persist and present as tumor-like lesions in imaging studies, potentially leading to false-positive interpretations as metastatic sites, affecting patient management. Our study aimed to enhance the diagnostic accuracy of radiologists in assessing gastric and colorectal cancer patients with fluorouracil implants.
