Use of a multimodal generative artificial intelligence model increased the efficiency and quality chest radiograph interpretations by reducing reading times increasing report accuracy agreement.
Purpose The purpose of this work was to describe the radiographic and CT findings in patients with respiratory bronchiolitis-associated interstitial lung disease (RB-ILD) correlate them clinical, physiologic, pathologic features. Method RB-ILD proved pathologically all 21 patients. Sixteen (76%) were current smokers, five (24%) ex-smokers. mean cigarette consumption 38.7 pack-years. Chest radiographs scans semiquantitatively analyzed correlated clinical findings, physiologic measures, a...

Idiopathic pulmonary fibrosis (IPF) is caused by alterations in expression of proteins involved multiple pathways, including matrix deposition, inflammation, injury, and repair.To understand the pathogenic changes lung protein IPF to evaluate apolipoprotein (Apo) A-I as a candidate therapeutic molecule.Two-dimensional electrophoresis was adopted for differential display proteomics. Reverse-transcriptase polymerase chain reaction, Western blotting, immunohistochemical staining, ELISA were...
Idiopathic interstitial pneumonia (IIP) is characterized by varying degrees of fibrosis. IL-13 and IL-4 are strong inducers tissue fibrosis, whereas IFN-gamma has antifibrotic potential. However, the roles these substances in IIP remain unknown. IL-13, IL-4, were measured BAL fluid 16 idiopathic pulmonary fibrosis (IPF) patients, 10 nonspecific (NSIP) 8 normal controls. The expression IL-13Ralpha1/alpha2 lung tissues was analyzed using ELISA immunohistochemistry. levels significantly higher...
The purpose of this article is to evaluate prospectively the utility sonographic measurements common extensor tendon for diagnosing lateral epicondylitis.Forty-eight patients with documented epicondylitis and 63 healthy volunteers were enrolled underwent ultrasound elbow joint. overlying bony landmark was scanned transversely, cross-section area maximum thickness measured. Clinical examination used as reference standard in diagnosis epicondylitis. Data from patient control groups compared...
Local overexpression of interleukin-6 (IL-6) experimentally induces lymphocytic infiltration in the bronchial tree rat. Among idiopathic interstitial pneumonia (IIP), nonspecific pneumonia/fibrosis (NSIP) has an increased number lymphocytes bronchoalveolar lavage (BAL) fluid when compared with usual (UIP). To reveal a relation IL-6 lymphocyte NSIP, was measured BAL fluids NSIP (n = 7), UIP 16), and normal control subjects 45). IL-6-producing sites were assessed by protein stain on biopsy...
OBJECTIVE. We describe the sonographic findings of nasal fracture in children, and we evaluate diagnostic value sonography as compared with conventional radiography clinical to determine whether can be a primary technique for evaluating children. MATERIALS AND METHODS. Conventional radiographs scans were obtained 26 consecutive children trauma who seen at our hospital from March 2003 2005. There five girls 21 boys, their ages ranged 1 year 9 months 15 years 11 (mean age, 9.9 years). The...
One of the clinical manifestations refractory asthma (RA) in a certain group patients is persistent airway obstruction (PAO), despite treatment with high doses inhaled and/or systemic corticosteroids. Airway neutrophilic inflammation frequently observed RA; however, relationship between and PAO has not been evaluated this patients. The aim study was to compare parameters patterns inflammatory cells or without due RA, identify factors associated PAO.Seventy-seven RA were recruited from cohort...
Purpose To prospectively compare the effectiveness of iterative decomposition water and fat with echo asymmetry least-squares estimation (IDEAL) T2-weighted contrast material–enhanced T1-weighted magnetic resonance (MR) imaging that a conventional MR protocol in minimizing metallic artifacts phantoms patients hardware after spinal surgery. Materials Methods Institutional review board approval informed consent were obtained for this study. Coronal T1- images six titanium alloy pedicle screws...
<i>Background:</i> Airway eosinophilia is frequently observed during acute exacerbation of asthma. Interleukin-5 (IL-5) and eotaxin are directly involved in the airway found persistent Interrelation between these cytokines expected to occur Thus, we evaluated relevance interaction IL-5 inflammation exacerbation. <i>Methods:</i> We measured number inflammatory cells amount sputum from 22 healthy subjects, 21 asthmatics with 16 patients mild asthma, reassessed values 7...
Utility of Postmortem Autopsy via Whole-Body Imaging: Initial Observations Comparing MDCT and 3.0T MRI Findings with FindingsObjective: We prospectively compared whole-body multidetector computed tomography (MDCT) magnetic resonance (MR) images autopsy findings. Materials Methods:Five cadavers were subjected to whole-body, 16channel MR imaging within two hours before an autopsy.A radiologist classified the findings into major minor findings, which findings.Results: Most pertaining head neck,...

Our aim was to evaluate whether high-resolution sonography can provide additional information concerning rib lesions compared with radiography or bone scintigraphy.Fifty-eight patients high-uptake seen on scintigraphy were selected. Radiography and performed these patients. High-resolution using a linear 5-12 MHz transducer. By means of clinical history, histopathologic examination, follow-up observation, classified into fracture (n = 37), metastasis 18), unknown 3) groups. images the 55...
Customarily used classification of IPF did not satisfy a sizable group patients with that in the past had been lumped UIP and now currently has begun to be recognized as nonspecific interstitial pneumonia/fibrosis (NIP). There are few reports about clinical features NIP.The pathologic slides 66 having open lung biopsy (OLB) for differential diagnosis diseases (ILD) from 1984 1995 were reviewed. Seven cases confirmed NIP. The record, pulmonary function tests (PFT), chest PA HRCT reviewed...
While pleural effusion in multiple myeloma is relatively infrequent, myelomatous extremely rare. We experienced a 61-year-old woman with IgD-lambda and effusion. The diagnosis was made originally by biopsy, fluid cytology immunoelectropheresis of fluid. Transient improvement the observed after administration combination chemotherapy vincristine, melphalan, cyclophosphamide, prednisone (VMCP)/vincristine, adriamycin, (VCAP). Two months later, recurred no response to salvage therapy observed....
To assess the radiologic findings of systemic arterial supply to normal basal segments left lower lobe, chest radiographs and CT scans all 11 patients were reviewed retrospectively by two radiologists. On posteroanterior (n = 11), anomalous artery arising from descending thoracic aorta was shown as a retrocardiac mass 11). Absence lobar pulmonary shadow partial obliteration aortic interface 9), increased interstitial markings in lung zone 8) also noted. contrast-enhanced abrupt tapering...

Primary pulmonary T-cell lymphoma is an extremely rare malady, and we diagnosed this in a 52-year-old male who was admitted to our hospital with cough for the previous two weeks. The chest CT demonstrated multiple variable sized mass-like consolidations low density central necrosis peripheral portion of both upper lower lobes. Positron emission tomography (PET) showed areas hypermetabolic fluorodeoxyglucose (FDG) uptake lungs metabolic defects, which correlated seen on CT. histological...
To assess the current practice patterns of radiologists who perform transthoracic needle biopsy (TNB).An email survey 71 questions on TNB was sent to 240 members Korean Society Thoracic Radiology. The answers multiple-choice (n = 56) were analyzed.Of 60 respondents, 45% had 10 or more years experience in chest radiology, and 70% 5 TNB. For question most frequently used diagnostic method for lesions with high probability being resectable-stage lung cancer, respondents answered that is...
A subset of asthmatics suffers from persistent airflow limitation, known as remodeled asthma, despite optimal treatment. Typical quantitative scoring methods to evaluate structural changes airway remodeling on high-resolution computed tomography (HRCT) are time-consuming and laborious. Thus, easier simpler required in clinical practice. We evaluated the usefulness a simple, semi-quantitative method based 8 HRCT parameters by comparing with decline post-bronchodilator (BD)-FEV1 those BD-FEV1...
