Computed tomography (CT)-guided pulmonary core biopsies of small nodules less than 15 millimeters (mm) are challenging for radiologists, and their diagnostic accuracy has been shown to be variable in previous studies. Common complications after the procedure include pneumothorax hemorrhage. The present study compared large lesions using CT-guided identified risk factors associated with post-procedure complications. Between January 1, 2016, December 31, 2017, 198 performed on 195 patients at...

Abstract Classical trigeminal neuralgia (TN) is a specific type of neuropathic orofacial pain which the plasticity brain structure and connectivity have remained largely unknown. A total 62 TN patients were included referred to MRI scans. Voxel‐based morphometry was used analyze change gray matter volume. Resting‐state functional imaging between regions. The results showed volume reduction in components prefrontal cortex, precentral gyrus, cerebellar tonsil, thalamus, hypothalamus, nucleus...

Abstract Hypertension (HTN) affects over 1.2 billion individuals worldwide and is defined as systolic blood pressure (BP) ≥ 140 mmHg diastolic BP 90 mmHg. also considered a high risk factor for cerebrovascular diseases, which may lead to vascular cognitive impairment (VCI). VCI associated with executive dysfunction transitional stage between hypertension dementia. Hence, it essential establish reliable approach diagnosing the severity of VCI. In 28 HTN (51–83 yrs; 18 males, 10 females)...

Purpose: Accurate segmentation of the cisternal segment trigeminal nerve plays a critical role in identifying and treating different nerve-related disorders, including neuralgia (TN). However, current manual process is prone to interobserver variability consumes significant amount time. To overcome this challenge, we propose deep learning-based approach, U-Net, that automatically segments nerve. Methods: evaluate efficacy our proposed U-Net model was trained validated on healthy control...

Background and purpose Recent large series studies have demonstrated that dehydration is common amongst stroke subjects associated with poor outcome.

In this study, hypothesis an important factor for developing after acute middle cerebral artery ( MCA ) infarction was tested. Methods Eighty‐seven patients due to occlusion were enrolled. Two collateral markers, posterior PCA laterality fluid‐attenuated...

Background Diffusion-restricted lesions on diffusion-weighted imaging (DWI) are detected in patients with intracerebral hemorrhage (ICH). In this study, we aimed to determine the fate of DWI ICH and whether presence is associated functional outcome ICH. Methods This prospective study enrolled 153 acute Baseline MRI scans were performed within 2 weeks after detect markers for small vessel disease (SVD). Follow-up at 3 months assess lesions. We analyzed associations between characteristics...

Objective Imaging the brachial plexus is a challenge because of its complicated structure. The purpose this study to improve diagnostic ability for via 3-dimensional T2-weighted short inversion time recovery (3D-T2-STIR) technique with contrast agent administration. Methods Thirty patients plexopathies were recruited. STIR sequences without and administration performed on each subject. grade ratio assessed. Results After administration, signals adjacent vessels suppressed reduced T1...

Objectives:Although diffusion tensor imaging (DTI) is widely studied to assess the motor outcome after ischaemic stroke, there paucity of data regarding outcomes intracerebral haemorrhage (ICH). The aim this study was determine DTI from different locations along corticospinal tract (CST) and association outcome.Methods:We prospectively recruited patients with deep ICH admitted our hospital November 2010 July 2012.Diffusion performed within 14 days onset ICH. Fractional anisotropy (FA)...

Our study aimed to clarify the neuroimaging correlates of suicide attempt by comparing differences in functional magnetic resonance imaging (fMRI) among depressed attempters, patients without history, and healthy controls through comprehensive novel fMRI analyses methods same population. The association between depression severity aspects brain was also discussed. recruited 109 participants who were assigned three groups: 33 with (SA), 32 (NS), 44 (HC). All scanned using a 3 T MRI system...

Abstract Background To explore the diagnostic performance of triggered angiography non-contrast-enhanced magnetic resonance imaging (TRANCE-MRI) for evaluation venous pathology lower extremity. Methods This was a single-centre prospective cohort study 25 patients with suspected disease in extremities. Each patient received Doppler ultrasonography (for evaluation) before scheduled TRANCE-MRI and arterial evaluations) on 1.5 T MR scanner (Philips Ingenia, Philips Healthcare, Best,...

Abstract As the performance of current fall risk assessment tools is limited, clinicians face significant challenges in identifying patients at falling. This study proposes an automatic prediction model based on eXtreme gradient boosting (XGB), using a data-driven approach to standardized medical records. analyzed cohort 639 participants (297 and 342 controls) from Chang Gung Memorial Hospital, Chiayi Branch, Taiwan. A derivation 507 (257 250 was collected for constructing XGB algorithm....

It is estimated that at least one million people die by suicide every year, showing the importance of prevention and detection. In this study, an autoencoder machine learning model was employed to predict with suicidal ideation based on their structural brain imaging. The subjects in our generalized q-sampling imaging (GQI) dataset consisted three groups: 41 depressive patients (SI), 54 without thoughts (NS), 58 healthy controls (HC). GQI dataset, indices fractional anisotropy (GFA),...

The hemodynamic changes of acute small subcortical infarction (SSI) are not well understood. We evaluate the and collaterals in SSI using perfusion magnetic resonance imaging (MRI). A total 103 patients with penetrating artery territories were recruited underwent MRI within 24 h stroke onset. Using 4D dynamic MRI, they divided into three patterns: 25 (24%) normal perfusion, 31 (30%) compensated 47 (46%) hypoperfusion. development anterograde or retrograde was also evaluated. Patients...
