Summary
A new telemedicine platform, BITScreen PTB, shows promise for improving pediatric tuberculosis diagnosis using chest X-rays in resource-limited areas. While sensitivity was low, high specificity suggests its utility for screening children with suspected TB.
Area of Science:
- Medical Imaging
- Public Health
- Digital Health
Background:
- Tuberculosis (TB) significantly impacts children globally, particularly those under five.
- Diagnosing pediatric TB is challenging due to limited access to accurate diagnostic tools in resource-limited settings.
Purpose of the Study:
- To introduce BITScreen PTB, a telemedicine web platform for evaluating pediatric pulmonary TB using digital chest X-rays (CXR) and clinical data.
- To enhance pediatric TB diagnosis and care in resource-limited environments.
Main Methods:
- Retrospective assessment of 218 pediatric CXR examinations by 3 expert readers.
- Evaluation of platform usability, assessment time, reader performance, and interreader agreement.
- Analysis of the association between CXR findings and initial diagnostic classification.
Main Results:
- The BITScreen PTB platform demonstrated high usability (average rating 4.4/5) and quick assessment times (35-110 seconds).
- CXR analysis showed low sensitivity (16.3%-28.2%) but high specificity (91.1%-98.2%) for pediatric TB.
- Air space opacification was strongly associated with initial diagnostic classification, with moderate/substantial interreader agreement for specific findings.
Conclusions:
- Telemedicine platforms like BITScreen PTB hold potential for improving access to pediatric TB diagnosis in underserved regions.
- These platforms can support systematic CXR assessment in pediatric TB research and clinical practice.

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
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...

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
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...

Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...

The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
