Imaging diagnosis analysis and literature review of intrapulmonary solitary fibrous tumor.

Background: Solitary fibrous tumor (SFT) of the chest mainly arises from the pleura, but intrapulmonary SFT is rare. This study aimed to review and discuss the chest multislice computed tomography (MSCT) and magnetic resonance imaging (MRI) findings of intrapulmonary SFT and summarize existing literature on the disease in order to improve clinicians' understanding and diagnosis of this disease.

Methods: The imaging findings and clinical data of 4 surgically and pathologically confirmed intrapulmonary SFT cases were retrospectively analyzed in terms of location, morphology, size, density, border, enhancement level of the lesion, and its relationship with surrounding tissue.

MSCT findings of primary Pulmonary mucoepidermoid carcinoma.

Objectives: To improve diagnostic accuracy of pulmonary mucoepidermoid carcinoma (PMEC) through multi-detector computed tomography (MSCT) findings.

Methods: MSCT findings of 27 histopathologically confirmed PMEC cases were retrospectively analyzed, including the location, size, margin, density, enhancement of the lesion and accompanying signs.

Results: Among the 27 PMEC cases, 6 (6/27, 22.

Correlation with Spectral CT Imaging Parameters and Occult Lymph Nodes Metastases in Sufferers with Isolated Lung Adenocarcinoma.

For investigating the correlation with spectral CT imaging parameters and occult lymph nodes metastasis in sufferers with isolated lung adenocarcinoma. The clinic cases data of 352 sufferers with isolated lung adenocarcinoma from January 2019 to January 2022 were assembled. In line with whether the sufferers had occult lymph nodes metastasis, they were taken as a part in the metastasis group ( = 172) and the nonmetastasis group.

[Imaging and Clinical Characteristics of Primary Pulmonary Mucoepidermoid Carcinoma].

Objective To improve the understanding and diagnostic accuracy of pulmonary mucoepidermoid carcinoma(PMEC) by analyzing the imaging and clinical characteristics.Methods The clinical and CT data of 27 cases of PMEC confirmed by histopathology in the First Medical Center of Chinese PLA General Hospital from January 2016 to December 2020 were retrospectively analyzed,including the location,size,margin,density,enhancement characteristics,accompanying signs,and pathological grade.Results The 27 cases included 6(6/27,22.

Assisting scalable diagnosis automatically via CT images in the combat against COVID-19.

The pandemic of Coronavirus Disease 2019 (COVID-19) is causing enormous loss of life globally. Prompt case identification is critical. The reference method is the real-time reverse transcription PCR (RT-PCR) assay, whose limitations may curb its prompt large-scale application.

[A clinical analysis of 40 cases of primary and secondary pulmonary lymphoma].

Objective: To investigate the clinical manifestations, pathological types, treatment and prognosis of primary pulmonary lymphoma (PPL) and secondary pulmonary lymphoma (SPL).

Methods: The clinical data of 40 cases of PPL or SPL diagnosed from 2003 to 2013 in the Chinese PLA General Hospital were retrospectively analyzed. All cases were diagnosed via lung biopsy or surgical biopsy.

Effectiveness of contrast-enhanced ultrasound in the classification and emergency management of abdominal trauma.

Objective: To analyse the correlation between contrast-enhanced ultrasound (CEUS)-based classification of the severity of abdominal parenchymal organ trauma and clinical outcomes, and to explore CEUS in classifying patients with such trauma, expecting that the use of CEUS will potentially enhance the quality and speed of the emergency management of abdominal trauma.

Methods: Three hundred six consecutive patients with blunt abdominal parenchymal organ trauma who received CEUS examination were retrospectively analysed. Two CEUS radiologists (identified as Reader A and Reader B in this study) who were not involved in the CEUS examinations of the patients were then asked to classify the patients independently according to their CEUS results.

Emergency contrast-enhanced ultrasonography for pancreatic injuries in blunt abdominal trauma.

Purpose: The purpose of this study was to retrospectively investigate the application of emergency contrast-enhanced ultrasonography (CEUS) in blunt pancreatic trauma.

Materials And Methods: Twenty-two consecutive patients with blunt pancreatic trauma were examined using CEUS from March 2007 to June 2012. The findings of CEUS were compared with those of contrast-enhanced computed tomography scans at level-1 diagnostic tests.

Percutaneous treatment of blunt hepatic and splenic trauma under contrast-enhanced ultrasound guidance.

The objective of this study was to evaluate the clinical application of hemostatic percutaneous therapy of liver and spleen trauma under contrast-enhanced ultrasound (CEUS) guidance. A total of 83 patients with 88 traumatic organ lesions were included in this study. Liver or spleen lesions were treated by percutaneous injection of haemocoagulase atrox and α-cyanoacrylate under CEUS guidance.

[CT characteristics of primary salivary gland-type lung cancer].

Objective: To improve the diagnostic accuracy of primary salivary gland-type lung cancer on CT.

Methods: The CT findings of 13 pathologically proven primary salivary gland-type lung cancers (mucoepidermoid carcinoma, n = 8, adenoid cystic carcinoma, n = 5) were retrospectively analyzed.

Results: Three mucoepidermoid carcinomas were located in the main bronchus, 4 in segmental bronchus, and 1 in peripheral lung.

Integrating PET and CT information to improve diagnostic accuracy for lung nodules: A semiautomatic computer-aided method.

Unlabelled: Our objective was to develop and evaluate 3 semiautomatic computer-aided diagnostic (CAD) schemes for distinguishing between benign and malignant pulmonary nodules by use of features extracted from CT, 18F-FDG PET, and both CT and 18F-FDG PET.

Methods: We retrospectively collected 92 consecutive cases of pulmonary nodules (<3 cm) in patients who underwent both thoracic CT and whole-body PET/CT. Forty-two of the nodules were malignant and 50 benign, as confirmed by pathologic examination and clinical follow-up.

Computer-aided diagnosis in thoracic CT.

Computer-aided diagnosis (CAD) provides a computerized diagnostic result as a "second opinion" to assist radiologists in the diagnosis of various diseases by use of medical images. CAD has become a practical clinical approach in diagnostic radiology, although, at present, primarily in the area of detection of breast cancer in mammograms. Currently, a large research effort has been devoted to the detection and classification of various lung diseases in thoracic computed tomography (CT) images.
