AJNR Am J Neuroradiol, 2023 • January 1, 2023
This case series describes 5 patients with intramedullary spinal neurosarcoidosis occurring at sites of spondylotic spinal canal stenosis. The clinical presentations and imaging findings can be indist...
KEY FINDING: Intramedullary spinal neurosarcoidosis can mimic spondylotic myelopathy both clinically and on imaging.
Neurosurgery, 2023 • February 1, 2023
This study evaluated the effectiveness of intraoperative ultrasound (IOUS) in assessing spinal cord decompression following surgery for cervical spinal cord injury, comparing it to postoperative MRI a...
KEY FINDING: IOUS demonstrated inadequate decompression after the preoperatively planned number of laminectomy levels in 5 cases (9.80%), prompting an additional half level of laminectomy in each, for a final judgement of adequate decompression in all 51 cases (100%).
Pol J Radiol, 2023 • January 19, 2023
This study evaluated a deep convolutional neural network (CNN) model for the automatic segmentation of the clinical target volume (CTV) in glioblastoma patients, aiming to improve the efficiency and c...
KEY FINDING: The proposed model achieved high segmentation accuracy with a Dice Similarity Coefficient (DSC) of 89.60 ± 3.56% and a Hausdorff distance of 1.49 ± 0.65 mm.
Diagnostic Pathology, 2023 • February 10, 2023
This case report describes a rare presentation of carotid body paraganglioma (CBT) with distant metastasis to the thoracic spine, resulting in spinal cord compression in a 40-year-old female. The pati...
KEY FINDING: Carotid body tumors, while typically benign, can exhibit metastatic potential, even many years after initial diagnosis and treatment.
Neurol Med Chir (Tokyo), 2023 • March 1, 2023
This study correlated CT and MRI findings in thoracolumbar burst fractures to evaluate PLC injury, finding that specific CT measurements like loss height, local kyphosis, and supraspinous distance are...
KEY FINDING: Loss of vertebral body height, local kyphosis, and supraspinous distance were significantly higher in patients with PLC injuries.
Not specified, null • March 16, 2023
This study introduces a reduced-Field-Of-View phase-segmented EPI (rFOV-PS-EPI) diffusion weighted MR pulse sequence to address geometric distortions near metal implants in DTI scans of the spinal cor...
KEY FINDING: The rFOV-PS-EPI method allows DTI measurement at the level of the metal hardware, whereas rFOV-SS-EPI is useful when the metal is approximately 20 mm away.
J. Clin. Med., 2023 • May 8, 2023
This review discusses the utility of MRI in assessing structural and functional changes in the central nervous system (CNS) in cervical spondylotic myelopathy (CSM). The review highlights various MRI ...
KEY FINDING: MRI methods, including T1-weighted and T2-weighted imaging, are used to assess macro-level tissue injury in the cervical spinal cord (CSC), but they may not detect minor abnormalities. More advanced MRI methods like diffusion-weighted imaging (DWI) can detect microstructural tissue injuries earlier in the disease progression.
Diagnostics, 2023 • April 14, 2023
This paper proposes a novel augmented model for spinal cord segmentation and tumor classification using deep nets to overcome this limitation. Multiple Mask Regional Convolutional Neural Networks (MRC...
KEY FINDING: The proposed model achieved a 14.5% better segmentation efficiency compared to state-of-the-art models.
Frontiers in Neurology, 2023 • May 5, 2023
This case report describes a 56-year-old male who developed a rare complication involving reperfusion injury in both the medulla oblongata and cervical cord following vertebral artery angioplasty and ...
KEY FINDING: Concomitant reperfusion injury in the medulla oblongata and cervical cord is extremely rare after vertebral artery angioplasty and stenting.
J Vet Intern Med, 2023 • July 1, 2023
This study investigates the characteristics of combined disc- and osseous-associated cervical spondylomyelopathy (CSM) in dogs using MRI and neurological examination. The findings indicate that a sign...
KEY FINDING: A substantial percentage of dogs with CSM (26% in this study) present with both IVD protrusion and osseous changes, often at the same location.
