AI Article Synopsis
- The study aimed to analyze MRI diffusion-weighted imaging (MR-DWI) characteristics of head and neck hemangiomas and venous malformations in children.
- By examining 10 hemangiomas and 40 venous malformations, the researchers measured the apparent diffusion coefficient (ADC) values with different b values using MR imaging.
- Results showed that there were significant differences in ADC values between hemangiomas and venous malformations, indicating that these imaging features can aid in the differential diagnosis of these conditions in children.
Article Abstract
Purpose: To analyze and evaluate the MR diffusion-weighted imaging (MR-DWI) features of head and neck hemangioma and venous malformation in children.
Methods: We retrospectively observed 10 head and neck hemangiomas and 40 head and neck venous malformations in children, which underwent both conventional MR imaging and MR-DWI. In the MR-DW images, the apparent diffusion coefficient(ADC) mean value was taken from b=500 s/mm² and 1000 s/mm², The data was analyzed using SPSS13.0 software package for t test.
Results: The mean ADC obtained from b value of 500 s/mm² was (1.227±0.324)x10⁻³mm²/s in hemangioma and (1.851±0.364)x10⁻³mm²/s in venous malformation, and from b value of 1000 s/mm² was (0.728±0.256)x10⁻³mm²/s in hemangioma and (1.200±0.228)x10⁻³mm²/s in vein malformation. There was significant difference between both lesions (P<0.01).
Conclusion: There are different features in MR-DWI between head and neck hemangioma and venous malformation in children, which may be helpful for radiological differential diagnosis.

Objectives: To investigate the characteristics of the vascular pedicle of the nasoseptal flap (NSF) and its perfusion patterns using intraoperative indocyanine green (ICG) angiography during endoscopic skull base surgery (ESBS), and examine the correlation between ICG perfusion patterns and clinical outcomes, including postoperative cerebrospinal fluid (CSF) leak and flap necrosis.
Methods: This study enrolled patients undergoing ESBS between January 2017 and December 2021. Intraoperative ICG angiography was performed to visualize the arterial supply of the nasal septum and evaluate NSF perfusion.

Objective: This study evaluated the effectiveness of laser Doppler flowmetry (LDF) in detecting perfusion disturbances during microvascular free tissue transfer.
Methods: Conducted at a single centre from December 2020 to September 2022, this prospective study involved 71 patients mainly undergoing head and neck free flap reconstructions, using the Pocket LDF™ for continuous perfusion monitoring.
Results: Out of the 71 cases, data from 69 cases were analysed after excluding those with significant noise or sensor detachment.
