Summary
Advances in CT technology allow for noninvasive imaging of large airways. This review covers airway anatomy, CT methods, and conditions like stenosis, neoplasms, and malacia using 3D reconstructions.
Area of Science:
- Radiology
- Pulmonary Medicine
- Medical Imaging
Background:
- Multidetector-row CT technology has significantly improved noninvasive imaging of the large airways.
- Advanced post-processing techniques enhance the visualization and assessment of tracheobronchial structures.
Purpose of the Study:
- To provide a comprehensive review of imaging techniques for the large airways.
- To discuss the application of CT in diagnosing various large airway pathologies.
Main Methods:
- Review of current literature on CT imaging of the large airways.
- Emphasis on the complementary roles of axial CT, multiplanar reformation (MPR), and three-dimensional (3D) reconstruction.
Main Results:
- CT enables detailed noninvasive assessment of airway anatomy and pathology.
- MPR and 3D reconstructions are crucial for comprehensive evaluation of stenoses, neoplasms, tracheobronchomalacia, and congenital abnormalities.
Conclusions:
- Modern CT technology and post-processing offer powerful tools for noninvasive large airway assessment.
- Integrated use of axial, MPR, and 3D images provides a complete understanding of large airway diseases.

01:13Radiological Investigation III: Pulmonary Angiogram and PET Scan
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

01:30Radiological Investigation II: MRI and Ventilation Perfusion Scan
Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

01:20Imaging Studies for Cardiovascular System III: X-Ray
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...

01:24X-ray Imaging
German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with X-rays, and by 1900, X-ray was widely...
01:27Imaging Studies III: Computed Tomography
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...
01:17Gross Anatomy of the Lungs
The lungs are a pair of vital organs connected to the trachea via the left and right bronchi. The base of these organs meets the dome-shaped muscle known as the diaphragm. Encased by the pleurae, the lungs contact the mediastinum. The right lung is shorter yet wider, and has a larger volume than the left lung. The left lung has an indentation known as the cardiac notch. The superior region of the lungs is referred to as the apex, whereas the base is the lower region near the diaphragm. The...
