Abstract Pelvic radiograph (PXR) is essential for detecting proximal femur and pelvis injuries in trauma patients, which also the key component survey. None of currently available algorithms can accurately detect all kinds trauma-related radiographic findings on PXRs. Here, we show a universal algorithm most types We develop multiscale deep learning called PelviXNet trained with 5204 PXRs weakly supervised point annotation. yields an area under receiver operating characteristic curve (AUROC)...

Abstract Computed tomography (CT) is the most commonly used diagnostic modality for blunt abdominal trauma (BAT), significantly influencing management approaches. Deep learning models (DLMs) have shown great promise in enhancing various aspects of clinical practice. There limited literature available on use DLMs specifically image evaluation. In this study, we developed a DLM aimed at detecting solid organ injuries to assist medical professionals rapidly identifying life-threatening...

Our study investigated whether tumor-associated macrophages (TAMs) in advanced non-small cell lung cancer (NSCLC) are related to treatment response epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) and may be a predictor of survival. Of 206 NSCLC patients treated (first-line) with an EGFR-TKI at the hospital from 2006 2009, 107 adequate specimens for assessing CD68 immunohistochemistry as marker TAMs were assessed. After treatment, was observed 55 (51%) patients, median...

Splenic injury is the most common solid visceral in blunt abdominal trauma, and high-resolution computed tomography (CT) can adequately detect injury. However, these lethal injuries sometimes have been overlooked current practice. Deep learning (DL) algorithms proven their capabilities detecting abnormal findings medical images. The aim of this study to develop a three-dimensional, weakly supervised DL algorithm for splenic on CT using sequential localization classification approach.The...

This case series illustrates the feasibility of single-stage image-guided video-assisted thoracoscopic surgery for simultaneous localization and removal small solitary pulmonary nodules (SPNs). The procedure was performed in a hybrid operating room using C-arm cone-beam computed tomography equipped with laser-guided navigation system.Between October 2016 January 2017, 12 consecutive patients presenting SPNs underwent surgery. safety were assessed through retrospective review patients'...

Background Hip fracture is the most common type of in elderly individuals. Numerous deep learning (DL) algorithms for plain pelvic radiographs (PXRs) have been applied to improve accuracy hip diagnosis. However, their efficacy still undetermined. Objective The objective this study develop and validate a human-algorithm integration (HAI) system diagnosis real clinical environment. Methods HAI with detection ability was developed using algorithm trained on trauma registry data 3605 PXRs from...

Preoperative chemoradiotherapy (CRT) followed by esophagectomy is becoming one of the standard treatment strategies for esophageal cancer. Pathologic complete response (pCR) after CRT best predictor survival in squamous cell carcinoma (SCC) esophagus. Although no adjuvant recommended individuals who achieve pCR, approximately 30% these patients develop recurrence. Herein we sought to retrospectively investigate independent predictors tumor recurrence this patient group.Between 1995 and 2004,...

Abstract Background This study aimed to evaluate the management of blunt splenic injury (BSI) and highlight role artery embolization (SAE). Methods We conducted a retrospective review all patients with BSI over 15 years. Splenic injuries were graded by 2018 revision American Association for Surgery Trauma-Organ Injury Scale (AAST-OIS). Our hospital provide 24/7 in-house surgeries interventional radiology facility. Patients who arrived hypotensive refractory resuscitation required surgery...

To compare the outcomes of blunt splenic injuries (BSI) managed with proximal (P) versus distal (D) combined (C) artery embolization (SAE).This retrospective study included patients BSI who demonstrated vascular on angiograms and were SAE between 2001 2015. The success rate major complications (Clavien-Dindo classification ≥ III) compared P, D, C embolizations.In total, 202 enrolled (P, n = 64, 31.7%; 84, 41.6%; C, 54, 26.7%). median injury severity score was 25. times from to 8.3, 7.0, 6.6...

Background: Detecting kidney trauma on CT scans can be challenging and is sometimes overlooked. While deep learning (DL) has shown promise in medical imaging, its application to injuries remains underexplored. This study aims develop validate a DL algorithm for detecting trauma, using institutional data the Radiological Society of North America (RSNA) dataset external validation. Methods: We developed RenoTrNet, model trained data. evaluated model’s performance through validation randomly...

Background: Immune checkpoint inhibitors (ICIs) have significantly changed the current approach to cancer treatment. Although use of ICIs has become standard care for advanced melanoma, reports ICI among Asian populations with melanoma are limited. Therefore, we conducted this retrospective study assess efficacy and safety in Taiwanese patients. Patients: Patients histologically confirmed treated at Linkou Chang Gung Memorial Hospital from January 2014 July 2019 were retrospectively...

To identify the feasibility and efficiency of deep convolutional neural networks (DCNNs) in detection ankle fractures to explore ensemble strategies that applied multiple projections radiographs.Ankle radiographs (AXRs) are primary tool used diagnose fractures.
