Purpose To develop and test a deep learning approach named Convolutional Neural Network (CNN) for automated screening of T 2 ‐weighted (T WI) liver acquisitions nondiagnostic images, compare this to evaluation by two radiologists. Materials Methods We evaluated 522 magnetic resonance imaging (MRI) exams performed at 1.5T 3T our institution between November 2014 May 2016 CNN training validation. The consisted an input layer, convolutional fully connected output layer. 351 WI were anonymized...
OBJECTIVE. The purpose of this study is to report unanticipated lung base findings on abdominal CT in 23 patients concerning for coronavirus disease (COVID-19). In these patients, who were not previously suspected having COVID-19, pain was the most common indication (n = 19), and 11 had no extrapulmonary findings. Seventeen underwent polymerase chain reaction testing, which returned positive results all 17.
Background Dual-energy CT enterography (DECTE) has been shown to be useful in characterizing Crohn disease activity compared with clinical markers of inflammation but, the knowledge authors, comparison not made histopathologic specimens. Purpose To compare mucosal iodine density obtained at DECTE from disease–affected bowel specimens surgically resected ileocolectomy segments or terminal ileum colonoscopic biopsies same patients. Materials and Methods This was a retrospective study. Bowel...
The purpose of this article is to describe arterial and venous thromboembolism in the abdomen, pelvis, lower extremities patients with coronavirus disease (COVID-19). Eighty-two COVID-19 who underwent abdominal ultrasound or CT were retrospectively compared 82 without for solid-organ infarction. Nine (11%) had thromboembolic findings, medium large thrombi five. One patient known portal vein thrombus on CT. Thromboembolic findings occurred more frequently than (p = 0.02).
Rationale and ObjectivesThe educational value of the daily resident readout, a vital component training, has been markedly diminished due to significant decrease in imaging volume case mix diversity. The goal this study was create "simulated" readout (SDR) restore readout.Materials MethodsTo SDR following tasks were performed; selection cases for worklist each rotation, comprising combination normal abnormal cases; determination correct number appropriate modalities worklist; development an...
OBJECTIVE. The objective of this article is to assess radiologist concordance in characterizing thyroid nodules using the American College Radiology Thyroid Imaging Reporting and Data System (TI-RADS), focusing on effect experience reader concordance. MATERIALS AND METHODS. Three experienced three less radiologists assessed 150 TI-RADS lexicon. Percent was determined for various endpoints. RESULTS. Interreader five categories 87.2% shape, 81.2% composition, 76.1% echogenicity, 72.9% margins,...
MR enterography (MRE) protocols used in patients with Crohn disease are burdened by long acquisition time, high cost, and suboptimal patient experience. For several indications, highly diagnostic MRE can be performed five or fewer sequences, without IV contrast material antiperistaltic medication an examination room time of less than 12 minutes. As such, could more friendly, frequently performed, require health care resources.
Understanding the unique features of photon-counting CT and being familiar with terminology setup processes are essential to effectively implement this modality in clinical practice.
Background: Osteoporosis is underdiagnosed and undertreated. Traditional screening methods like dual-energy X-ray absorptiometry have limitations, prompting the exploration of opportunistic using CT artificial intelligence (AI). Purpose: To develop a reproducible robust AI-based method to automatically assess spine trabecular attenuation on noncontrast CTs, irrespective protocol or scanner model used during imaging acquisition, establish normative values in large diverse population. Methods:...
Abstract Dual-energy computed tomography (DECT) has been available for clinical use since 2006. Since its debut, multiple different dual energy systems have developed including sequential acquisition, rapid-switching, dual-source, and twin-beam, in addition to spectral imaging techniques such as dual-layer photon counting CT. While the specifics of these vary, underlying principles remain same; by acquiring at least two data sets, material specific information each image voxel can be...
The aim of this study was to compare portal venous phase photon-counting CT (PCCT) using 20 cc less than weight-based contrast dosing with energy-integrating detector (EID-CT) by quantitative and qualitative analysis.
