Computed Tomography

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Pulmonary Tuberculosis IV

Pulmonary Tuberculosis IV

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...

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Pulmonary Tuberculosis III

Pulmonary Tuberculosis III

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Pulmonary Tuberculosis II

Pulmonary Tuberculosis II

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Pulmonary Tuberculosis I

Pulmonary Tuberculosis I

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
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...

Summary

High Resolution Computed Tomography (HRCT) reveals common patterns in new pulmonary tuberculosis (PTB) cases. Centrilobular nodules and lobular consolidations were most frequent, aiding in diagnosis.

Background:

Pulmonary Tuberculosis (PTB) remains a significant global health challenge.
Accurate and early diagnosis of PTB is crucial for effective treatment and control.
High Resolution Computed Tomography (HRCT) offers detailed imaging of lung parenchyma.

Purpose of the Study:

To identify and characterize the common HRCT patterns in adult patients with newly diagnosed, Acid Fast Bacillus (AFB) positive Pulmonary Tuberculosis (PTB).

Main Methods:

A descriptive case series study was conducted.
Fifty adult patients with AFB-positive new PTB were included.
HRCT of the chest was performed using 2 mm collimation at 10 mm intervals.

Main Results:

The most frequent HRCT findings included centrilobular nodules (92%), lobular consolidation (84%), and cavitation (76%).
Common HRCT patterns observed were centrilobular nodules with lobular consolidation (80%), centrilobular nodules with cavitation (72%), and centrilobular nodules with 'tree-in-bud' appearance (68%).

Conclusions:

Centrilobular nodules and lobular consolidations represent a hallmark HRCT pattern in new PTB cases.
HRCT findings like centrilobular nodules with cavitation and 'tree-in-bud' appearance are highly prevalent.
These characteristic HRCT patterns are valuable for the diagnosis of new pulmonary tuberculosis in adults.
