Continuous Generation of Volumetric Images During Stereotactic Body Radiation Therapy Using Periodic kV Imaging and an External Respiratory Surrogate [PDF]
arXiv, 2018 We present a technique for continuous generation of volumetric images during SBRT using periodic kV imaging and an external respiratory surrogate signal to drive a patient-specific PCA motion model. Using the on-board imager, kV radiographs are acquired every 3 seconds and used to fit the parameters of a motion model so that it matches observed changes

Synthetic Tumors Make AI Segment Tumors Better [PDF]
arXiv, 2022 We develop a novel strategy to generate synthetic tumors. Unlike existing works, the tumors generated by our strategy have two intriguing advantages: (1) realistic in shape and texture, which even medical professionals can confuse with real tumors; (2) effective for AI model training, which can perform liver tumor segmentation similarly to a model ...

Fatty images of the heart: spectrum of normal and pathological findings at computed tomography and cardiac magnetic resonance imaging. [PDF]
, 2018 Ectopic cardiac fatty images are not rarely detected incidentally at computed tomography and cardiac magnetic resonance, either in exams focused on the heart as in general thoracic imaging evaluations.

Annals of Clinical and Translational Neurology, Volume 12, Issue 3, Page 523-537, March 2025.Abstract Objective To characterize structural integrity of the lumbosacral enlargement and conus medullaris within one month after spinal cord injury (SCI). Methods Lumbosacral cord MRI data were acquired in patients with sudden onset (<7 days) SCI at the cervical or thoracic level approximately one month after injury and in healthy controls.

The Multi-Biomarker Approach for Heart Failure in Patients with Hypertension [PDF]
, 2015 We assessed the predictive ability of selected biomarkers using N-terminal pro-brain natriuretic peptide (NT-proBNP) as the benchmark and tried to establish a multi-biomarker approach to heart failure (HF) in hypertensive patients. In 120 hypertensive

The Biological Basis for Cardiac Repair After Myocardial Infarction: From Inflammation to Fibrosis.
Circulation Research, 2016 In adult mammals, massive sudden loss of cardiomyocytes after infarction overwhelms the limited regenerative capacity of the myocardium, resulting in the formation of a collagen-based scar.

Right‐sided vagus nerve stimulation: Worldwide collection and perspectives
Annals of Clinical and Translational Neurology, Volume 12, Issue 3, Page 565-576, March 2025.Abstract Objective Vagus nerve stimulation (VNS) is an established therapy for drug‐resistant epilepsy (DRE) and is indicated for implantation on the left vagus nerve‐only. In rare cases right‐sided VNS may be the only option. With only seven published cases in the literature, data on safety and effectiveness of right‐sided VNS is very limited ...

Cerebral Embolism due to a Large Papillary Fibroelastoma arising from the Coumadin Ridge
Clinical Case Reports, 2019 A 70‐year‐old woman developed acute cerebral infarction. Transthoracic echocardiography showed a large mobile mass in the left atrium, suggesting cardiac myxoma as the most likely diagnosis.

Multi-Task Generative Adversarial Network for Handling Imbalanced Clinical Data [PDF]
arXiv, 2018 We propose a new generative adversarial architecture to mitigate imbalance data problem for the task of medical image semantic segmentation where the majority of pixels belong to a healthy region and few belong to lesion or non-health region. A model trained with imbalanced data tends to bias towards healthy data which is not desired in clinical ...
