Evaluation of Chest X-ray and Thoracic Computed Tomography in Patients with Suspected Tuberculosis: Correspondence

Background and Objective. Chest X-ray is recommended for routine use in patients with suspected pneumonia, but its use in emergency settings is limited. In this study, the diagnostic performance of a new method for quantitative analysis of lung ultrasonography was compared with bedside chest X-ray and visual lung ultrasonography for detection of community-acquired pneumonia, using thoracic computed tomography as a gold standard.Methods. Thirty-two spontaneously breathing patients with suspected community-acquired pneumonia, undergoing computed tomography examination, were consecutively enrolled. Each hemithorax was evaluated for the presence or absence of abnormalities by chest X-ray and quantitative or visual ultrasonography.Results. Quantitative ultrasonography showed higher sensitivity (93%), specificity (95%), and diagnostic accuracy (94%) than chest X-ray (64%, 80%, and 69%, resp.), visual ultrasonography (68%, 95%, and 77%, resp.), or their combination (77%, 75%, and 77%, resp.).Conclusions. Quantitative lung ultrasonography was considerably more accurate than either chest X-ray or visual ultrasonography in the diagnosis of community-acquired pneumonia and it may represent a useful first-line approach for confirmation of clinical diagnosis in emergency settings.

Abstract Background There is no consensus on the imaging modality to be used in the diagnosis and management of Coronavirus disease 2019 (COVID-19) pneumonia. The purpose of this study was to make a comparison between computed tomography (CT) and chest X-ray (CXR) through a scoring system that can be beneficial to the clinicians in making the triage of patients diagnosed with COVID-19 pneumonia at their initial presentation to the hospital. Results Patients with a negative CXR (30.1%) had significantly lower computed tomography score (CTS) (p < 0.001). Among the lung zones where the only infiltration pattern was ground glass opacity (GGO) on CT images, the ratio of abnormality seen on CXRs was 21.6%. The cut-off value of X-ray score (XRS) to distinguish the patients who needed intensive care at follow-up (n = 12) was 6 (AUC = 0.933, 95% CI = 0.886–0.979, 100% sensitivity, 81% specificity). Conclusions Computed tomography is more effective in the diagnosis of COVID-19 pneumonia at the initial presentation due to the ease detection of GGOs. However, a baseline CXR taken after admission to the hospital can be valuable in predicting patients to be monitored in the intensive care units.

Prompt Diagnosis

Abstract Gastric volvulus is a rare abnormal rotation of the stomach along its axis. It is a surgical emergency, hence requires prompt diagnosis and treatment to prevent life-threatening gangrenous changes. Hence, a high index of suspicion is required in any patients presenting with an acute abdomen in emergency. The entity can present acutely with pain abdomen and vomiting, or as chronic with non-specific symptoms. Chest X-ray findings to diagnose it may be overlooked in patients with acute abdomen. Here, we report three patients with gastric volvulus, where the diagnosis was based on the chest X-ray findings, confirmed with computed tomography, and managed successfully with surgery.

Upper Gastrointestinal

Blood expectoration or hemoptysis is the coughing up of sputum with blood from the larynx, bronchi or lungs. Hemoptysis is most often caused by diseases of the respiratory tract and lungs — bronchitis or pneumonia, as well as lung cancer, aspergilloma, tuberculosis, bronchiectasis, pulmonary embolism, etc. In the diagnostic investigation of the cause of hemoptysis, it is important to take a detailed history (in the case of an epidemiological history, a laboratory analysis of the secreted sputum for the detection of the causative agent of an infectious disease is necessary), to make the correct interpretation of the patient’s complaints and an assessment of the nature of the sputum (differential diagnosis with bleeding from the upper gastrointestinal tract). A chest X-ray is performed and, then, if indicated, computed tomography, bronchoscopy, and other studies are made. The article presents an algorithm for differential diagnostic investigation of hemoptysis in a patient

Pericardial masses include cysts, pericardial tumours, and pericardial haematomas. Pericardial cysts are benign lesions commonly located in the right cardiophrenic angle that remain typically asymptomatic and are incidentally found in chest X-ray or chest computed tomography but might cause pressure symptoms or become infected, thus requiring surgical management. Hydatid cysts due to echinococcosis are the most common acquired pericardial cysts, characterized by wall calcification, and indicate surgery.

Chest X Ray

Both the detection and interpretation of focal abnormalities on chest X-ray (CXR) are challenging tasks. CXR accuracy depends on the view (e.g. the supine view has limited sensitivity) and technological equipment. The detection of small focal abnormalities (e.g. lung nodules) varies between anatomical regions according to the presence of dense anatomic structures, such as the bones and the hila. The interpretation of focal abnormalities on CXR is paramount within the whole clinical assessment, because CXR findings can guide the patient’s management, or warrant further investigations, such as computed tomography. Focal lung abnormalities on CXR are still a cornerstone of diagnostic algorithms; however, the radiological approach has progressively changed in the last decade because of the progressive development of both hardware and software applications that enable sensitive detection and accurate characterization.
