Abstract Novel Coronavirus (COVID-19) has drastically overwhelmed more than 200 countries affecting millions and claiming almost 2 million lives, since its emergence in late 2019. This highly contagious disease can easily spread, if not controlled a timely fashion, rapidly incapacitate healthcare systems. The current standard diagnosis method, the Reverse Transcription Polymerase Chain Reaction (RT- PCR), is time consuming, subject to low sensitivity. Chest Radiograph (CXR), first imaging...
The newly discovered Coronavirus Disease 2019 (COVID-19) has been globally spreading and causing hundreds of thousands deaths around the world as its first emergence in late 2019. rapid outbreak this disease overwhelmed health care infrastructures arises need to allocate medical equipment resources more efficiently. early diagnosis will lead separation COVID-19 non-COVID cases, which be helpful for authorities optimize resource allocation plans prevention disease. In regard, a growing number...
Abstract Novel Coronavirus disease (COVID-19) is a highly contagious respiratory infection that has had devastating effects on the world. Recently, new COVID-19 variants are emerging making situation more challenging and threatening. Evaluation quantification of lung abnormalities based chest Computed Tomography (CT) images can help determining stage, efficiently allocating limited healthcare resources, informed treatment decisions. During pandemic era, however, visual assessment lesions by...
Reverse transcription-polymerase chain reaction is currently the gold standard in COVID-19 diagnosis. It can, however, take days to provide diagnosis, and false negative rate relatively high. Imaging, particular chest computed tomography (CT), can assist with diagnosis assessment of this disease. Nevertheless, it shown that dose CT scan gives significant radiation burden patients, especially those need multiple scans. In study, we consider low-dose ultra-low-dose (LDCT ULDCT) protocols...
The global outbreak of the novel corona virus (COVID-19) disease has drastically impacted world and led to one most challenging crisis across globe since World War II. early diagnosis isolation COVID-19 positive cases are considered as crucial steps towards preventing spread flattening epidemic curve. Chest Computed Tomography (CT) scan is a highly sensitive, rapid, accurate diagnostic technique that can complement Reverse Transcription Polymerase Chain Reaction (RT-PCR) test. Recently, deep...
Spontaneous pneumothorax (SPT) and pneumomediastinum (SPM) have been reported as uncommon complications of coronavirus disease (COVID-19) pneumonia. The exact incidence risk factors are still unrecognized. We report 6 nonventilated, COVID-19 pneumonia cases with SPT SPM their outcomes. major for development in our patients were male gender, advance age, pre-existing lung disease. These may occur the absence mechanical ventilation associated increasing morbidity (chest tube insertion, sepsis,...

Cardiovascular magnetic resonance (CMR) cine imaging is still limited by long acquisition times. This study evaluated the clinical utility of an accelerated two-dimensional (2D) sequence with deep learning reconstruction (Sonic DL) to decrease time without compromising quantitative volumetry or image quality.
Objectives: Pneumothorax and pneumomediastinum are associated with high mortality in invasively ventilated coronavirus disease 2019 (COVID-19) patients; however, the rates among non-intubated patients remain unknown. We aimed to analyze clinical features of COVID-19-associated pneumothorax/pneumomediastinum identify risk factors for mortality. Methods: searched PubMed Scopus Embase from January 2020 December 2021. performed a pooled analysis 151 no invasive mechanical ventilation history 17...
Chimeric antigen receptor T-cell therapy is a novel immunotherapy with promising results for patients advanced malignancies (1). Cytokine Release Syndrome an adverse effect of this therapy, associated multi-organ, including cardiovascular complications We describe case CAR-T cell cardiotoxicity and the multimodality imaging findings. A 74-year-old woman known hypertension, hypothyroidism, psoriasis, fibromyalgia internal jugular vein thrombosis was admitted (CAR-T) due to relapsed/refractory...
Erdheim-Chester disease (ECD) as a rare non-Langerhans histiocytosis has various clinical manifestations. It is characterized histologically by infiltration of every organ, more commonly bone, retroperitoneum, cardiovascular and CNS systems with foamy, lipid -laden macrophage. Pancreatic involvement manifestation this uncommon very rarely been reported. Here we report 73-year-old woman ECD pancreas in CT, MRI PET scans. We also aim to increase radiologist knowledge about considering...
The simultaneous presence of Takayasu's arteritis and Crohn's disease in a patient seems to be rare. To our knowledge, no with the combination has been reported from region.Herein we present case 22-year-old Iranian woman previously diagnosed as who had subsequently developed arteritis.Clinical suspicion, proper imaging, consideration differential diagnosis are important for correct management patients this coincidence.
The unprecedented COVID-19 pandemic has been remarkably impacting the world and influencing a broad aspect of people's lives since its first emergence in late 2019. highly contagious nature raised necessity developing deep learning-based diagnostic tools to identify infected cases early stages. Recently, we proposed fully-automated framework based on Capsule Networks, referred as CT-CAPS, distinguish infection from normal Community Acquired Pneumonia (CAP) using chest Computed Tomography...
The novel Coronavirus disease (COVID-19) has been the most critical global challenge over past months. Lung involvement quantification and distinguishing types of infections from chest CT scans can assist in accurate severity assessment COVID-19 pneumonia, efficient use limited medical resources, saving more lives. Nevertheless, visual images evaluating by radiologists are expensive prone to error. This paper proposes an automated deep learning (DL)-based framework for multi-class...
We report the case of a 45-year old male with metastatic colon cancer who presented chest pain and transient diffuse ST-segment elevation on electrocardiogram after his third cycle FOLFOX (folinic acid, fluorouracil, oxaliplatin). Initial transthoracic echocardiogram showed reduced left ventricular ejection fraction 35% mildly elevated troponins. Further investigations cardiovascular magnetic resonance imaging demonstrated recovery function evidence suggestive coronary vasospasm. This will...
The novel Coronavirus disease, COVID-19, has rapidly and abruptly changed the world as we knew in 2020. It becomes most unprecedent challenge to analytic epidemiology general signal processing theories specific. Given its high contingency nature adverse effects across world, it is important develop efficient processing/learning models overcome this pandemic be prepared for potential future ones. In regard, medical imaging plays an role management of COVID-19. Human-centered interpretation...
Epipericardial fat necrosis (EPFN) is a rare, benign cause of acute chest pain imitating symptoms life-threatening diseases, such as coronary syndrome. Here We report 37-year-old, healthy male presented to the emergency department (ED) with sudden-onset pleuritic after an isometric physical training. Initial cardiac workup included ECG, echocardiography was unremarkable, but diagnosis inflammatory process that involved epipericardial tissue surrounding heart made by showing encapsulated...
