Tuberculosis: Diagnostic imaging and treatment challenges
Journal Title: International Journal of Medical and Health Research - Year 2017, Vol 3, Issue 1
Abstract
Tuberculosis is a potentially lethal disease if not diagnosed and treated early. Diagnosing Tuberculosis can be a challenge that can perplex even the most experienced clinicians. Clinical manifestations are nonspecific, typical chest radiograph findings may not be evident till late in the disease, high resolution computed tomography (HRCT) shows randomly distributed nodules and is relatively more sensitive. Ultrasonography, CT and magnetic resonance imaging (MRI) are useful in discerning the extent of organ involvement by lesions of Tuberculosis in extra-pulmonary locations. Fundus examination for choroid tubercles, histopathological examination of tissue biopsy specimens, conventional and rapid culture methods for isolation of Mycobacterium tuberculosis, drug-susceptibility testing, along with use of molecular biology tools in sputum, body fluids, other body tissues are useful in confirming the diagnosis. Although several prognostic markers have been described which predict mortality, yet untreated Tuberculosis has a fatal outcome within one year.
