head imagingintracranial hemorrhageThe use of a noncontrast head computed tomography (CT) is more often becoming part of the screening tools in the emergency department for multiple neurologic and traumatic complaints. Head CT scan is of the utmost importance for interpretation in a timely and ...

To examine the added diagnostic value of emergent contrast enhanced CT head (CECTH) in patients who present to the emergency department (ED) with acute non-traumatic symptoms referable to the brain, and to assess the financial implications of CECTH in the emergent setting.We queried healthcare ...
We hypothesized that there was a statistically significant increase in the rate of census-adjusted head CTs performed for mild trauma after March 16, 2009, compared to prior to this date. We included all with a non-contrast head CT performed from the emergency department (ED) between March 1...
Dual-energy CT (DECT) material decomposition techniques may better detect edema within cerebral infarcts than conventional non-contrast CT (NCCT). This study compared if Virtual Ischemia Maps (VIM) derived from non-contrast DECT of patients with acute ischemic stroke due to large-vessel occlusion (...
Handcrafted and deep learning (DL) radiomics are popular techniques used to develop computed tomography (CT) imaging-based artificial intelligence models for COVID-19 research. However, contrast heterogeneity from real-world datasets may impair model per
AIM: To investigate the feasibility of noncontrast computed tomography (NcCT) and perfusion CT (PCT) in the assessment of head deceleration injury (HDI).: A small animal HDI device was developed. A total of 20 healthy adult with frontal impacts resulting from a 3.5 m drop were included in ...
The purpose of the present study was to determine the diagnostic accuracy of non-enhanced CT and contrast-enhanced CT in integrated PET/CT studies for preoperative nodal staging of rectal cancer. Retrospective analysis was performed in 53 patients with pathologically proven rectal cancer who had been...
Conclusions and Relevance In patients undergoing proximal anterior circulation mechanical thrombectomy in the extended time window, there were no significant differences in the clinical outcomes of patients selected with noncontrast CT compared with those selected with CTP or MRI. These findings have the ...
This project aimed to develop and evaluate a fast and fully-automated deep-learning method applying convolutional neural networks with deep supervision (CNN-DS) for accurate hematoma segmentation and volume quantification in computed tomography (CT) scans. Non-contrast whole-head CT scans of 55 patien...
