Imaging Studies for Cardiovascular System III: X-Ray01:20

Imaging Studies for Cardiovascular System III: X-Ray

142
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...

Chest Physiotherapy01:24

Chest Physiotherapy

382
Chest Physiotherapy (CPT) is a therapeutic technique used in respiratory care to improve ventilation, clear bronchial secretions, and enhance the efficiency of respiratory muscles. This therapy includes three primary procedures: postural drainage, percussion, and vibration. It can be performed on spontaneously breathing patients and those who are intubated and mechanically ventilated.
Purpose
CPT is primarily used for patients with excessive bronchial secretions who have difficulty clearing...

Radiological Investigation I: X-ray and CT

209
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...

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs

236
Asthma is a chronic respiratory condition for which new therapeutic avenues, including anti-inflammatory drugs like mast cell stabilizers and anti-IgE treatments, continue to be developed.
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

Area of Science:

  • Pulmonary Medicine
  • Radiology
  • Medical Imaging

Background:

  • Modern pulmonary imaging techniques offer detailed insights into lung pathologies in asthma.
  • Traditional lung function measurements have limitations in capturing the full spectrum of asthma-related changes.

Purpose of the Study:

  • To explore the role and advancements of various imaging modalities in understanding asthma.
  • To highlight the clinical implications of imaging-based biomarkers in asthma diagnosis and treatment.

Main Methods:

  • Utilizing computed tomography (CT), magnetic resonance imaging (MRI), optical coherence tomography (OCT), and endobronchial ultrasound (EBUS).
  • Analyzing imaging-derived biomarkers such as airway dimensions, blood vessel volumes, mucus scores, ventilation defects, and air trapping.
  • Comparing the sensitivity of imaging biomarkers with traditional lung function measurements.

Main Results:

  • Imaging biomarkers demonstrate increased sensitivity compared to traditional lung function tests.
  • Imaging is crucial for understanding the link between type 2 inflammation, eosinophilia, and mucus.
  • CT and MRI can predict and explain patient response to anti-type 2 biologic therapies.
