Spine image analysis is based on the accurate segmentation and vertebrae recognition of the spine. Several deep learning models have been proposed for spine segmentation and vertebrae recognition, but they are very computationally demanding. In this research, a novel deep learning model is introduced for spine segmentation and vertebrae recognition using CT images. The proposed model works in two steps: (1) A cascaded hierarchical atrous spatial pyramid pooling residual attention U-Net (CHASPPRAU-Net), which is a modified version of U-Net, is used for the segmentation of the spine. Cascaded spatial pyramid pooling layers, along with residual blocks, are used for feature extraction, while the attention module is used for focusing on regions of interest. (2) A 3D mobile residual U-Net (MRU-Net) is used for vertebrae recognition. MobileNetv2 includes residual and attention modules to accurately extract features from the axial, sagittal, and coronal views of 3D spine images. The features from these three views are concatenated to form a 3D feature map. After that, a 3D deep learning model is used for vertebrae recognition. The VerSe 20 and VerSe 19 datasets were used to validate the proposed model. The model achieved more accurate results in spine segmentation and vertebrae recognition than the state-of-the-art methods.

A 41-year-old man with a history of obesity, hypertension, and smoking suffered from numbness and weakness in both lower limbs. He was diagnosed with ossification of the posterior longitudinal ligament and ligamentum flavum in the cervical and thoracic spine by X-rays, CT, and MRI. The patient underwent laminectomies at T2 and T3 levels, along with posterior fusion from T1 to T4, to address an upper thoracic spine lesion causing sensory deficits up to T5 and gait disturbances.

Objectives: Three-dimensional (3D) ultrasound imaging can overcome the limitations of conventional two-dimensional (2D) ultrasound imaging in structural observation and measurement. However, conducting volumetric ultrasound imaging for large-sized organs still faces difficulties including long acquisition time, inevitable patient movement, and 3D feature recognition. In this study, we proposed a real-time volumetric free-hand ultrasound imaging system optimized for the above issues and applied it to the clinical diagnosis of scoliosis.

Background: Aneurysmal subarachnoid hemorrhage (aSAH) is often associated with acute high-pressure hydrocephalus. Less commonly, an acute low-pressure hydrocephalus (ALPH) variant can develop and contribute to increased morbidity. ALPH is particularly challenging to diagnose and manage, as patients present with symptoms of increased intracranial pressure (ICP) despite the absence of corroborating evidence from ICP measurements.
