Diagnostic Value of Multi-Slice Spiral Computed Tomography for Bronchial Dysplasia in Premature Infants.
Diagnostic Value of Multi-Slice Spiral Computed Tomography for Bronchial Dysplasia in Premature Infants. Med Sci Monit. 2018 Oct 15;24:7375-7381 Authors: Zhang W, Wang S Abstract BACKGROUND The aim of this study was to investigate the diagnostic value of multi-slice spiral computed tomography (MSCT) for bronchial dysplasia in premature infants. MATERIAL AND METHODS A retrospective analysis of 248 premature infants who were highly suspected to have bronchial dysplasia and were admitted to our hospital from 2015 onwards was conducted. We observed bronchus morphologies, sizes, and tissue characteristics using fiberoptic bronchoscopy (FB) as the criterion standard for diagnosis. We calculated the sensitivity, specificity, and diagnostic compliance of MSCT in the diagnosis of bronchial dysplasia. RESULTS Thoracic computed tomography mainly revealed capsular bubbles. The translucency of the 2 lungs was reduced, and extensive and local ground-glass changes were observed. Imaging findings mostly included strip or honeycomb-like shadows. Pleural thickening and pleural effusion were rare. MSCT was able to establish a diagnosis in 92 cases (37.10%) of bronchopulmonary cysts, 69 cases (27.82%) of congenital pulmonary emphysema, 31 cases (12.50%) of bronchial atresia, 1 case (0.40%) of congenital cystadenoma malformation, and 3 cases (1.21%) of giant tracheal bronchitis. Another 52 children (20.97%) were found to have conventional pulmonary inflammation. The sensitivi...
Congenital IVC atresia is a rare risk factor for lower extremity DVT. Detailed medical histories can uncover alternative thrombotic risk factors that may explain these patients ’ anatomic abnormalities and predisposition for DVT. We investigate if IVC atresia is typically congenital or more often a secondary process.
To evaluate the ability of pre-procedural CTA to predict the technical success of embolization of post-EVAR type II endoleaks arising from lumbar arteries.
To develop a model to estimate drug dose delivered to the liver following transarterial chemoembolization (TACE) with radiopaque drug-eluting beads (RO DEB) based on bead density and cone-beam computed tomography (CBCT) in a woodchuck hepatoma model.
Computed tomography (CT) interventions are often performed using a helical acquisition technique while the operator is in a control room. We compare an axial technique using a gantry-side pedal to the helical technique for chest biopsies in terms of time, number of acquisitions, and radiation dose to operator and patient.
This study aims to evaluate the utility of second look imaging in patients with persistent clinical concern for LGIB after initial negative CTA.
Many institutions advocate for obtaining arterial (Art), non-contrast (NC), and delayed (Del) phases when assessing for active lower gastrointestinal bleed (LGIB) on multiphasic computed tomography arteriograms (CTA). We aimed to evaluate the necessity of all three phases of CTA for accurate diagnosis of active LGIB.
To evaluate the outcomes after computed tomography (CT)-guided sacroiliac (SI) joint injections in patients suspected to have lower back pain from SI joint instability.
Transbronchial microwave (MW) ablation is a recently developed bronchoscopic therapy for small pulmonary malignancies. X-ray based guidance techniques would allow interventional radiologists to perform the procedure. The purpose of this study was to assess the feasibility and target accuracy of using cone-beam CT (CBCT) with augmented fluoroscopy to navigate airways.
This study was performed to test the hypothesis that contrast-enhanced CT scan can help identify “high-risk” esophageal varices in cirrhotic patients.
To determine if systolic blood pressure and hemoglobin concentration impact detection of acute traumatic hemorrhage/extravasation on our institutional trauma computed tomography (tCT) protocol.
