Summary
Multimodal imaging, including multicolor imaging, enhances visualization of angioid streaks (AS) and associated retinal changes. This non-invasive approach aids in clearly delineating these lesions for better diagnosis.
Area of Science:
- Ophthalmology
- Medical Imaging
- Retinal Diseases
Background:
- Angioid streaks (AS) are characterized by crack-like dehiscences in Bruch's membrane.
- AS are frequently linked to atrophic degeneration of the retinal pigment epithelium (RPE).
Observation:
- Multimodal imaging was employed to visualize AS and related fundus findings.
- Multicolor imaging distinctly highlighted AS in a dark orange hue.
- Infrared reflectance provided superior visualization of AS compared to green and blue reflectance imaging.
Findings:
- Peau d'orange appearance presented as alternating dark and bright patches on color fundus photography.
- Infrared reflectance correlated with hyporeflective and hyperreflective patches corresponding to the peau d'orange.
- Comet lesions exhibited increased signal on infrared reflectance and hyperautofluorescence.
Implications:
- Multicolor imaging offers a non-invasive method for precise delineation of angioid streaks.
- Advanced imaging techniques improve the understanding and diagnosis of conditions associated with angioid streaks.
- Enhanced visualization aids in the assessment of RPE atrophy and other associated pathologies.

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...

298
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...

235
Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

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...

Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...
