Objectives:
This study evaluated the efficacy of radiographic screening for tuberculosis in correctional facilities.
Methods:
Inmates at an admission facility in New York, NY, were screened for tuberculosis by registry cross-match, symptom interviews, tuberculin testing, and chest radiography.
Results:
Thirty-two cases of tuberculosis were detected among 4172 inmate admissions (767 cases per 100,000). Twenty-five inmates (78%) were previously diagnosed but incompletely treated; all were identified by registry cross-match. Seven inmates (22%) were newly diagnosed, of whom four (57%) were asymptomatic, had negative skin tests, and were detected only by their abnormal radiographs.
Conclusions:
Screening strategies that limit radiographic testing to inmates with either positive skin tests or symptoms may result in missed opportunities for diagnosing active tuberculosis.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
Mode of...
Pulmonary Tuberculosis III
The first classification is based on the development of the disease, and it includes the following categories:
Pulmonary Tuberculosis IV
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
Pulmonary Tuberculosis V
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the progression...
Radiological Investigation I: X-ray and CT
Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
