Abstract Background High-resolution computed tomography (HRCT) chest becomes a valuable diagnostic tool for identifying patients infected with Coronavirus Disease 2019 (COVID-19) in the early stage, where patients may be asymptomatic or with non-specific pulmonary symptoms. An early diagnosis of COVID-19 is of utmost importance, so that patients can be isolated and treated in time, eventually preventing spread of the disease, improving the prognosis and reducing the mortality. In this paper, we have highlighted our radiological experience of dealing with the pandemic crisis of 2020 through the study of HRCT thorax, lung ultrasonography, chest X-rays and artificial intelligence (AI). Results Results of CT thorax analysis have been given in detail. We had also compared CT severity score (CTSS) with clinical and laboratory parameters. Correlation of CTSS with SpO2 values and comorbidities was also studied. We also analysed manual CTSS with the CTSS scored calculated by the AI software. Conclusions CTSS and use of COVID-19 Reporting and Data System (CORADS) result in accuracy and uniform percolation of information among the clinicians. Bed-side X-rays and ultrasonography have played a role where the patients could not be shifted for CT scan. The possibility of predicting impending or progression of hypoxia was not possible when SpO2 mapping was correlated with the CTSS. AI was alternatively tried with available software (CT pneumonia analysis) which was not so appropriate considering the imaging patterns in the bulk of atypical category.

Background: Chronic obstructive pulmonary disease (COPD) is a common preventable and treatable disease characterised by persistent respiratory symptoms and airflow limitation with varied presentations (bronchitis and emphysema). High resolution computed tomography (HRCT) plays an important role in identifying the various morphologies thereby reducing morbidity and mortality. The aim of the present study was to evaluate the role of high resolution computed tomography in COPD patients. The Objectives of the present study was to differentiate emphysema predominant, airway predominant and mixed phenotypes and to identify other disease processes and complications.Methods: 50 COPD patients attending Respiratory medicine Department, NRI general hospital were advised for chest x-rays and pulmonary function tests. All the patients selected were smokers with no other co-morbid illnesses. Those patients whose chest x-rays showed no other changes except for COPD changes were selected for HRCT chest.Results: Out of 50 COPD patients emphysema predominance was present in 28 patients (56%), bronchitis predominance in 19 patients (38%) and 3(6%) patients had mixed pattern. In emphysema centriacinar pattern was commonly seen (42.9%), paraseptal in 35.71%, panacinar in 3.57% and bullae in 17.8% cases. All the patients were chronic smokers with pack years >20. All are males with average age above 45 years. Emphysema was common in elderly patients with age above 50 years. Chronic bronchitis is predominantly seen in the age group 40-50 years. Additional diagnoses like bronchiectasis, mass, ILD were identified in 28% cases.Conclusions: HRCT plays a significant role in COPD patients in differentiating phenotypes which have different modes of therapy. Other subtle changes in lungs which cannot be identified on chest x ray are discernible on HRCT. Early identification of complications reduces morbidity and mortality.

The aim of our research was analysis and comparison of chronic obstructive lung disease clinicalsigns and function indices of external respiration apparatus and inspiratory-expiratory high resolution computed tomography. 48 patients with chronic obstructive lung disease were examined. The importance of respiration biomechanics and inspiratory-expiratory high resolution computed tomography indices for diagnostics of broncho-obstruction at an early stage with unchanged forced expiration volume within the first second was revealed.

Background: Many imaging modalities have been in use for the evaluation of temporal bone lesions. Plain X-rays are cost-effective however; they provide limited details and hence sometimes may result in an inaccurate diagnosis. With the advent of HRCT, the method of imaging of temporal bone has evolved with special algorithms and multiplanar formats. In the present study, we tried to evaluate the different pathologies of the temporal bone with X-ray and HRCT. Methods: The study was conducted in the Departments of Otorhinolaryngology and Radiology, Prathima Institute of Medical Sciences, Naganoor, Karimnagar. A total of n=40 patients were identified and selected based on their symptoms and clinical findings suggestive of a lesion involving the temporal bone such as Otalgia, Otorrhoea, And Sensorineuronal deafness, pulsatile tinnitus, vertigo, and giddiness. These patients were subjected to high resolution computed tomography of the temporal bone on the 128 Slice CT Scanner (PHILIPS INGENUITY). The patients also underwent plain Radiography of temporal bone (CARESTREAM DRX-1 System). Results: Of the total n=40 patients studied the most common temporal bone disease was due to inflammation 85% and tumors were found in 15% of the patients. The common site of involvement of middle ear and mastoid air cells in chronic otitis media was epitympanum in n=30(90%) of cases, Mesotympanum in n=20(60%) of cases. In diseased ears, radiographs of the mastoids revealed pneumatised mastoid in 6(15%), diploic in 6(15%), and sclerosed mastoid in 28(70%) cases. HRCT temporal bone revealed pneumatised mastoid in 9(22.5%), diploic in 5(12.5%) and sclerosed mastoid in 26(65%) cases. Conclusion: The role of plain radiography is found to be limited to know the type of mastoid pneumatisation. It can also as Original Article detect bony erosion in few cases. Because of the ability to see temporal bone structures with great clarity, HRCT can be recommended not only in cases suspected with potential complications but also in all cases of temporal bone pathologies to know the extent of disease, inter-relationships of the tympanomastoid compartment with adjacent neurovascular structures, varied pneumatisation and the presence of anatomical variations, which should alert the clinician and guide in surgical approach and treatment plan.

Parenchymal Lung Disease

Hypersensitivity pneumonitis (HP), also referred to as extrinsic allergic alveolitis, is an allergic inflammatory parenchymal lung disease usually caused by inhalational exposure to organic antigens from microbial bioaerosols or animal sources encountered in the work or home environment. Patients with HP can present with wheezing and obstructive abnormalities leading to an incorrect asthma diagnosis. The presence of a gas exchange abnormality, bronchoalveolar lavage lymphocytosis, and characteristic infiltrative changes on high-resolution computed tomography of the chest can be used to distinguish HP from asthma. The early diagnosis of HP and cessation of exposure to causative antigens result in remission of the disease and no residual impairment.
