Radiological Investigation II: MRI and Ventilation Perfusion Scan

240
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...

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

Imaging Studies for Cardiovascular System III: X-Ray

308
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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

180
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...

Cystic Fibrosis: Pathogenesis01:23

Cystic Fibrosis: Pathogenesis

384
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Area of Science:

  • Radiology
  • Pulmonology
  • Pathophysiology

Background:

  • Cystic lung diseases (CLDs) are a diverse group of lung conditions characterized by gas-filled lesions.
  • Their varied mechanisms and unpredictable progression make diagnosis challenging for clinicians.
  • Accurate differentiation from other cystic lung mimics is essential.

Purpose of the Study:

  • To provide a comprehensive diagnostic approach for cystic lung diseases.
  • To highlight the role of high-resolution computed tomography (HRCT) in evaluating CLDs.
  • To present a systematic algorithm for radiologists in diagnosing CLDs.

Main Methods:

  • Utilizing high-resolution computed tomography (HRCT) as a primary diagnostic tool.
  • Differentiating true cysts from mimics like emphysema, honeycombing, and bronchiectasis.
  • Analyzing cyst characteristics: number, distribution, wall thickness, and associated systemic findings.

Main Results:

  • HRCT enables accurate characterization of CLDs, often obviating the need for lung biopsy.
  • Identification of key radiological features aids in classifying CLDs based on pathophysiological mechanisms.
  • A systematic diagnostic algorithm is proposed to guide radiologists.
