Radiological Investigation III: Pulmonary Angiogram and PET Scan01:13

Radiological Investigation III: Pulmonary Angiogram and PET Scan

145
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...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

197
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...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

32
Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Radiological Investigation I: X-ray and CT

363
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...

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

Imaging Studies for Cardiovascular System III: X-Ray

287
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...

Imaging Studies VII: Vascular Imaging

48
DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

    Area of Science:

    • Rheumatology and Immunology
    • Systemic Autoimmune Diseases

    Context:

    • Vasculitis is a systemic inflammatory condition affecting blood vessels.
    • It can be primary (idiopathic) or secondary to other conditions like autoimmune diseases, infections, or tumors.
    • Rare but serious complications include pulmonary hemorrhage and glomerulonephritis.

    Purpose:

    • To review the clinical, radiological, and pathological features of vasculitis.
    • To elaborate on imaging findings and differential diagnoses for lung-predominant vasculitis.
    • To introduce the new international Diagnostic and Classification Criteria in Vasculitis.

    Summary:

    • Vasculitis involves inflammation of the vascular wall, presenting with diverse, non-specific symptoms.
    • Diagnosis necessitates a comprehensive approach, integrating clinical presentation, imaging, autoantibody tests, and pathology.
    • The review covers key features and diagnostic tools, including the latest international classification.

    Impact:

    • Enhances understanding of vasculitis diagnosis and classification.
    • Provides a valuable resource for clinicians managing patients with vasculitis.
    • Facilitates accurate diagnosis and appropriate management of this complex disease.
