Minute changes of cerebral parenchymal non-contrast computed tomography attenuation reflect cerebral volume alterations of blood.

The neuroradiology journal

Uchizawa T.
PMID: 33657930
Neuroradiol J. 2021 Aug;34(4):341-347. doi: 10.1177/1971400921998981. Epub 2021 Mar 03.

AIMS: Non-infarcted acute cerebral ischaemic areas appear hypo-attenuated on non-contrast narrow-window computed tomography images. We aimed to determine the mechanism underlying minute computed tomography hypo-attenuation and visualise these attenuation changes on non-contrast computed tomography images.METHODS: The cerebral parenchyma was...

Am J Pathol. 2021 Oct;191(10):1717-1723. doi: 10.1016/j.ajpath.2021.02.024. Epub 2021 Apr 08.

Many modern histopathology laboratories are in the process of digitizing their workflows. Digitization of tissue images has made it feasible to research the augmentation or automation of clinical reporting and diagnosis. The application of modern computer vision techniques, based...

Deformable registration of chest CT images using a 3D convolutional neural network based on unsupervised learning.

Journal of applied clinical medical physics

Zheng Y, Jiang S, Yang Z.
PMID: 34505341
J Appl Clin Med Phys. 2021 Oct;22(10):22-35. doi: 10.1002/acm2.13392. Epub 2021 Sep 10.

PURPOSE: The deformable registration of 3D chest computed tomography (CT) images is one of the most important tasks in the field of medical image registration. However, the nonlinear deformation and large-scale displacement of lung tissues caused by respiratory motion...

Alleviating Class-Wise Gradient Imbalance for Pulmonary Airway Segmentation.

IEEE transactions on medical imaging

Zheng H, Qin Y, Gu Y, Xie F, Yang J, Sun J, Yang GZ.
PMID: 33970858
IEEE Trans Med Imaging. 2021 Sep;40(9):2452-2462. doi: 10.1109/TMI.2021.3078828. Epub 2021 Aug 31.

Automated airway segmentation is a prerequisite for pre-operative diagnosis and intra-operative navigation for pulmonary intervention. Due to the small size and scattered spatial distribution of peripheral bronchi, this is hampered by a severe class imbalance between foreground and background...

Hemorrhagic stroke lesion segmentation using a 3D U-Net with squeeze-and-excitation blocks.

Computerized medical imaging and graphics : the official journal of the Computerized Medical Imaging Society

Abramova V, Clèrigues A, Quiles A, Figueredo DG, Silva Y, Pedraza S, Oliver A, Lladó X.
PMID: 33901919
Comput Med Imaging Graph. 2021 Jun;90:101908. doi: 10.1016/j.compmedimag.2021.101908. Epub 2021 Apr 14.

Hemorrhagic stroke is the condition involving the rupture of a vessel inside the brain and is characterized by high mortality rates. Even if the patient survives, stroke can cause temporary or permanent disability depending on how long blood flow...

A Lightweight Fusion Distillation Network for Image Deblurring and Deraining.

Sensors (Basel, Switzerland)

Zhang Y, Liu Y, Li Q, Wang J, Qi M, Sun H, Xu H, Kong J.
PMID: 34450762
Sensors (Basel). 2021 Aug 06;21(16). doi: 10.3390/s21165312.

Recently, deep learning-based image deblurring and deraining have been well developed. However, most of these methods fail to distill the useful features. What is more, exploiting the detailed image features in a deep learning framework always requires a mass...
