HRCTCov19-a high-resolution chest CT scan image dataset for COVID-19 diagnosis and differentiation.

INTRODUCTION: Computed tomography (CT) was a widely used diagnostic technique for COVID-19 during the pandemic. High-Resolution Computed Tomography (HRCT), is a type of computed tomography that enhances image resolution through the utilization of advanced methods. Due to privacy concerns, publicly available COVID-19 CT image datasets are incredibly tough to come by, leading to it being challenging to research and create AI-powered COVID-19 diagnostic algorithms based on CT images. DATA DESCRIPTION: To address this issue, we created HRCTCov19, a new COVID-19 high-resolution chest CT scan image collection that includes not only COVID-19 cases of Ground Glass Opacity (GGO), Crazy Paving, and Air Space Consolidation but also CT images of cases with negative COVID-19. The HRCTCov19 dataset, which includes slice-level and patient-level labeling, has the potential to assist in COVID-19 research, in particular for diagnosis and a distinction using AI algorithms, machine learning, and deep learning methods. This dataset, which can be accessed through the web at http://databiox.com , includes 181,106 chest HRCT images from 395 patients labeled as GGO, Crazy Paving, Air Space Consolidation, and Negative.

AVF of superficial temporal vessels after thread brow lift, report of a case.

This report presents iatrogenic arteriovenous fistula of superficial temporal vessels after thread brow lift, which emphasizes on consideration of such rare complications during the procedure. A young woman presented with pulsatile mass of scalp after tread brow lift. Color Doppler and duplex sonography of the mass revealed an AVF (arteriovenous fistula) of superficial temporal vessels, a complication that in a few articles has been mentioned. Patient had received conservative treatment and the mass became very small and about to be disappeared. physicians must be aware of possible vascular injury during thread face lift and should be trained enough to avoid it.
