Insights

High-resolution computed tomography (HRCT) identifies four basic interstitial lung disease (ILD) patterns. Radiologists can use these HRCT patterns and clinical data for diagnosis, but collaboration is often needed.

Area of Science:

  • Radiology
  • Pulmonology
  • Medical Imaging

Background:

  • High-resolution computed tomography (HRCT) is crucial for diagnosing and monitoring interstitial lung disease (ILD).
  • Accurate ILD diagnosis relies on interpreting complex imaging patterns.

Purpose of the Study:

  • To systematically review HRCT patterns of ILD.
  • To discuss differential diagnoses for ILD based on HRCT findings.
  • To provide a diagnostic roadmap for radiologists managing ILD.

Main Methods:

  • Systematic review of HRCT patterns in ILD.
  • Analysis of pattern localization within the secondary pulmonary lobule (SPL).
  • Consideration of lung distribution (e.g., lobe predominance).

Main Results:

  • Four basic HRCT patterns of ILD identified: linear/reticular, nodular, high attenuation, and low attenuation.
  • Patterns are further classified by SPL localization (centrilobular, perilymphatic) and lung distribution.
  • Clinical data (smoking history, disease course) aid diagnosis.

Conclusions:

  • HRCT patterns and anatomical distribution aid ILD diagnosis in some cases.
  • Morphological and clinical overlap necessitates collaboration between clinicians, radiologists, and pathologists for definitive ILD diagnosis.

Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features

Chronic bronchitis is a key phenotype of chronic obstructive pulmonary disease (COPD), characterized by airway-centered inflammation and mucus overproduction. It develops from long-term exposure to harmful particles or gases, most commonly cigarette smoke, which triggers a persistent inflammatory response.Cellular and Structural ChangesInflammation initially affects the large bronchi and later the smaller airways, with infiltration by immune cells, including neutrophils, macrophages, and...

Chronic Obstructive Pulmonary Disease IV: Clinical Manifestations

Chronic Obstructive Pulmonary Disease, or COPD, is a long-term condition marked by persistent and only partially reversible airflow limitation. It involves two overlapping conditions—chronic bronchitis and emphysema—which often co-appear but differ in dominant symptoms and underlying mechanisms.Chronic Bronchitis FeaturesChronic bronchitis presents with a persistent productive cough and thick, sometimes purulent mucus due to airway inflammation, enlarged mucus glands, and goblet...

Other Pulmonary Disorders

Respiratory disorders encompass a range of conditions with varying levels of severity. Asthma, marked by chronic airway inflammation and hypersensitivity, is one such condition. It can lead to airway obstruction due to factors like bronchial spasms, mucosal edema, increased mucus secretion, or epithelial damage. Asthma triggers are diverse, ranging from allergens to emotional upset, and treatment focuses on both immediate relief through bronchodilators and long-term inflammation suppression.

Chronic Obstructive Pulmonary Disease II: Emphysema01:23

Chronic Obstructive Pulmonary Disease II: Emphysema

Emphysema, a major phenotype of chronic obstructive pulmonary disease (COPD), is characterized by irreversible destruction of alveolar walls and permanent enlargement of distal airspaces. Unlike chronic bronchitis, which primarily affects the airways, emphysema predominantly involves the lung parenchyma, where structural damage leads to airflow limitation.PathophysiologyIt most commonly results from prolonged exposure to cigarette smoke and other toxic gases, particularly cigarette smoke.

Pulmonary Hypertension: Classification and Pathogenesis01:30

Pulmonary Hypertension: Classification and Pathogenesis

Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

Pulmonary Tuberculosis III01:31

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:
