High resolution computed tomography and chest x-ray findings in patient with pulmonary tuberculosis
Journal of Chitwan Medical College, 2019
Background: Pulmonary Tuberculosis (PTB) is a major public health problem in Nepal. Diagnosis of pulmonary tuberculosis is done by bacteriological confirmation of respiratory specimen however Negative smear needs clinical and radiological evaluation for the diagnosis in suspected patient. This study focuses on radiological findings in both Pulmonary bacteriologically confirmed (PBC) and pulmonary clinically diagnosed (PCD) Tuberculosis. Methods: This observational study was conducted at Chitwan Medical College between Feb 2019 to July 2019. 45 Patient diagnosed with PTB were enrolled. Chest X-ray (CXR) and High Resolution Computed Tomography (HRCT) chest reports were analysed for the presence of findings that suggest active infection like cavity, consolidation, tree in bud, etc in PBC and PCD. Results: A total of 45 PTB patients with mean age: 54.60 ± 19 years were included. 53.3 % were PBC and 46.7 % were PCD tuberculosis, CXR findings in PBC and PCD tuberculosis was nodular inf...

Background/Objective: Tuberculosis (TB) is one of the most common worldwide infections, especially in developing countries. Early diagnosis is very important for prevention of the chronic form of the disease and sequel formation. Chest x-ray (CXR) is an easy, feasible, nonexpensive and quick tool for the diagnosis of pulmonary tuberculosis. Patients and Methods: We retrospectively evaluated 200 chest x-rays of secondary pulmonary TB cases in university-affiliated hospitals. These cases were all proved by a positive sputum smear or culture for mycobacterium tuberculosis. Results: In this study, we correlated CXR findings of 100 male and 100 female patients. The peak age of involvement in both groups was 61-80 years. None of the chest x-rays were normal. The main radiographic findings were consolidation-infiltration, fibrosis, pleural effusion, cavitation, pleural thickening and bronchiectasis. Mediastinal lymphadenopathy was detected in 9% of the cases. Pulmonary infiltration with co...

Introduction-Tuberculosis is one of India major public health problems. Though it’s treatable, but still umpteen number of people are afflicted every year with high morbidity and mortality. Early diagnosis is the essence in the management of pulmonary tuberculosis to prevent further progression of disease and permanent damage by fibrosis. The objectives of our study are: 1) To evaluate spectrum of pulmonary abnormalities on HRCT in patients with suspected PTB but with both normal and abnormal chest radiograph. 2) To determine the value of HRCT in predicting disease activity in Pulmonary Tuberculosis. 3) To determine the pattern of HRCT findings in active & inactive Pulmonary Tuberculosis. Material and method This prospective study in which data has been collected from 66 suspected patients of pulmonary tuberculosis from August 2015 to November 2016 who were referred to the department of radio diagnosis, GRMC, Gwalior from department of medicine and department of chest TB for evaluation. Well informed consent was obtained and each suspected patient of pulmonary tuberculosis underwent chest X ray using MARS 50/FC/ALLPOSE, ALLENGER and HRCT using a 128-slice volume scanner (SIEMENS SOMATOM Definition AS+: 95157) and sputum smear examination for AFB. Images were assessed for pattern and distribution of lung abnormalities. Result: Male preponderance was noted with majority of them belonging to 50-59 yr of age group.Majority of patients belong to active tuberculosis with a percentage of 57.5%(56+1.5%),next was relapsing tuberculosis.Final diagnosis of active tuberculosis correlates well with sputum examination which was 100% accurate.X RAY chest diagnosed active TB in 22 cases and all were AFB positive on sputum examination.Sputum smear examination is investigation of choice for diagnosis of TB,but the sensitivity is low .HRCT is helpful in differentiating active vs inactive TB better than plain chest radiograph and recognizing extent of pulmonary TB. Conclusion: HRCT can be beneficial in certain cases, imparting crucial information for the diagnosis and management of the disease. HRCT is advocated if tuberculosis is suspected clinically and the chest X-ray findings are normal or inconclusive; for authentication of diagnosis and discernment of activity
Chest X Ray findings in New Sputum Positive Pulmonary Tuberculosis
IOSR Journals, 2019
Background: Tuberculosis remains a worldwide public health problem. The guidelines of RNTCP suggest sputum as the initial diagnostic test for Tuberculosis. If sputum test is positive in patients who are receiving Anti tubercular therapy (ATT), without undergoing chest X-Ray. The sequel of tuberculosis of Lung can have a chronic affect on patients. Aim: The aim of this study was to determine whether new sputum positive pulmonary tuberculosis (PTB) patients must undergo chest X-Ray as a part of the initial diagnosis and treatment of PTB. Materials and Methods: 100 patients who attended our OPD with cough and sputum for two weeks with and without HIV infection underwent sputum AFB. The diagnosis of PTB was made on the basis of clinical history, physical examination, Ziehl-Neelsen microscopy (AFB stain) on two sputum samples. Chest X-Ray was done for the sputum positive patients. The findings were recorded for each radiograph. Results: Among the 70 sputum positive patients, 55 (78.57%) were male, 15 (21.42%) were female. Out of 70 patients with Tuberculosis 67 have Chest radiograph appearances in this group the cavitation, miliary pattern, t statistical trend towards less pleural effusion as well as hilar lymphadenopathy. Conclusion: Our observations suggest that normal finding in CXR is an exception and implementing chest x-ray as an additional test in new sputum positive patients will be helpful in extent of damage of lungs and the future complications that results if patient is not compliant ATT in the Indian setting
Chest radiographs and their reliability in the diagnosis of tuberculosis
2005
Radiology plays an important role in the diagnosis of pulmonary tuberculosis. Many medical practitioners believe in and rely primarily on the chest x-ray for the diagnosis of pulmonary tuberculosis. This study attempts to evaluate the reliability and validity of chest radiographs. This study was carried out in the tuberculosis clinic of BPKIHS. 75 radiographs were chosen for the study and viewed by 25 physicians of varying qualifications. Their findings were compared with the gold standard. The overall sensitivity and specificity was 78% and 51% respectively. There was poor agreement between the best physician and the best radiologist. This study has demonstrated an unsatisfactory sensitivity and specificity of chest x-rays in the diagnosis of pulmonary tuberculosis. The over-diagnosis and over-treatment due to chest x-rays could lead to an unmanageable burden on the resources of a poor country like Nepal. Private practitioners should be made aware about the importance of bacteriological diagnosis of tuberculosis before initiating drug therapy.

We assessed the effect of an interpretation grid on the detection of CXR anomalies and radiographic diagnosis of tuberculosis in an endemic area for tuberculosis. Methods: The study was conducted in Yaounde (Cameroon). Six observers (2 pulmonologists, 2 radiologists and 2 senior residents in medical imaging) interpreted 47 frontal CXR twice two months apart without (R1) and with (R2) the aid of an interpretation grid. We focused on the detection of micro nodules (n = 16), cavitations (n = 12), pleural effusion (n = 6), adenomegaly (n = 6), and diagnosis of tuberculosis (n = 23) and cancer (n = 7). Results: The average score for accurate detection of elementary lesions was 40.4% [95%CI: 25% -58.3%] in R1 and 52.1% [36.9% -65.3%] in R2. The highest improvement was observed for micro nodules (19.8%). Cavitations had the highest proportions of accurate detections (58.3% in R1 and 65.3% in R2). The average score of accurate diagnosis was 46.1% in R1 and 57.4% in R2. Accurate diagnosis improved by 3.6% for tuberculosis and 19% for cancer between R1 and R2. Intra-observer agreement was higher for the diagnosis of cancers * Corresponding author.
