OBJECTIVES While computed tomography colonography (CTC) has become a non-invasive alternative to traditional colonoscopy, superficial lesions tend be harder detect, with reports of <2 mm in height being missed. Therefore, for the evaluation lesion detectability using CTC, optimizing scan parameters becomes important. In this study, we investigate effect reconstructed matrix size from CTC on con...
BACKGROUND AND PURPOSE The purpose of this study was to show that the computer segmentation algorithm Iterative Self-Organizing Data Analysis Technique (ISODATA), which integrates multiple MRI parameters (diffusion-weighted imaging [DWI], T2-weighted imaging [T2WI], and T1-weighted imaging [T1WI]) into a single composite image, is capable of defining the ischemic lesion in a time-independent ma...
Recovery of hand function following lesions in the primary motor cortex (M1) is associated with a reorganization of premotor areas in the ipsilesional hemisphere, and this reorganization depends on the size of the lesion. It is not clear how lesion size affects motor representations in the contralesional hemisphere and how the effects in the 2 hemispheres compare. Our goal was to study how lesi...
Shoulder surgeons need to be aware of the critical size of the glenoid or humeral osseous defects seen in patients with anterior shoulder instability, since the considerable size of osseous defect is reported to cause postoperative instability. Biomechanical studies have identified the size of the osseous defect which affects stability. Since engagement always occurs between a Hill-Sachs lesion...
conclusion lesion depth from the pleural surface and the presence of emphysema were strongly correlated with the increasing incidence of pneumothorax after ct-guided pcnb. our results may be applicable for the risk management of pcnbs to reduce pneumothorax as a complication. background previous studies identifying risk factors for pneumothorax in percutaneous core needle lung biopsies reported...
