Imaging Studies for Cardiovascular System V: CT01:28

Imaging Studies for Cardiovascular System V: CT

502
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 for Cardiovascular System VI: Calcium -Scoring CT

735
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...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

422
The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

611
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...

Acute Coronary Syndrome III: Diagnostic Studies

384
Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Area of Science:

  • Vascular Surgery
  • Radiology
  • Medical Imaging

Background:

  • Multidetector CT (MDCT) has significantly advanced CT angiography.
  • It offers improved visualization for vascular applications.

Purpose of the Study:

  • To evaluate the utility of MDCT in patients with aortoiliac and branch aneurysms or stenosis.
  • To compare MDCT with Digital Subtraction Angiography (DSA) before and after endovascular repair.

Main Methods:

  • Twenty-one patients with aortoiliac and branch aneurysms or stenosis were included.
  • Both MDCT and DSA were performed before and after endovascular repair.

Main Results:

  • MDCT accurately assessed aneurysm dimensions, graft patency, thrombosis, and endoleaks.
  • For stenotic lesions, MDCT provided detailed information on graft characteristics and distal flow.

Conclusions:

  • MDCT is a potentially useful imaging modality for the initial evaluation of patients undergoing endovascular repair.
  • MDCT is also beneficial for the follow-up assessment of these patients.
