Imaging Studies for Cardiovascular System II:Types of Echocardiography01:20

Imaging Studies for Cardiovascular System II:Types of Echocardiography

964
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...

Imaging Studies II: Ultrasonography

909
IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

973
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...

The Thyroid Gland01:23

The Thyroid Gland

7.0K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Imaging Studies for Cardiovascular System V: CT

671
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Imaging Studies VII: Vascular Imaging

558
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:

  • Radiology and Imaging
  • Endocrinology
  • Histopathology

Background:

  • Thyroiditis diagnosis can be challenging, requiring accurate imaging modalities.
  • Ultrasonography (USG) and color flow Doppler (CFD) are non-invasive imaging techniques with potential for evaluating thyroid conditions.

Purpose of the Study:

  • To determine the efficacy of ultrasonogram in evaluating thyroiditis.
  • To compare the results of ultrasonogram with color flow Doppler study.
  • To correlate sonographic findings with histopathological diagnoses.

Main Methods:

  • A cross-sectional study involving 50 patients with suspected thyroiditis.
  • All patients underwent ultrasonography and color flow Doppler examinations.
  • Fine Needle Aspiration Cytology (FNAC) was performed for histopathological diagnosis and correlation.

Main Results:

  • Ultrasonography revealed irregular margins in 58% of patients, decreased echogenicity in 78%, and heterogeneous patterns in 88%.
  • Color flow Doppler showed increased vascularity in 38% and decreased vascularity in 34% of patients.
  • Histopathological diagnosis identified Hashimoto's thyroiditis in 34%, lymphocytic thyroiditis in 24%, and granulomatous thyroiditis in 18%.

Conclusions:

  • Ultrasonography and color flow Doppler are recommended as cost-effective and non-invasive diagnostic modalities for thyroiditis.
  • These imaging techniques demonstrate good correlation with histopathological findings, supporting their utility in clinical practice.
