Imaging Studies for Cardiovascular System V: CT

Imaging Studies for Cardiovascular System V: CT

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

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...

Acute Coronary Syndrome III: Diagnostic Studies

Acute Coronary Syndrome III: Diagnostic Studies

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...

Imaging Studies for Cardiovascular System IV: CMRI

Imaging Studies for Cardiovascular System IV: CMRI

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,...

Imaging Studies VII: Vascular Imaging

Imaging Studies VII: Vascular Imaging

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...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Summary

This study compares ultrasound (US) and computed tomography (CT) for diagnosing mesenteric ischemia. While CT is definitive, US shows promise as a safe initial imaging tool for acute cases.

Background:

Intestinal ischemia is a critical abdominal emergency affecting about 2% of gastrointestinal illnesses.
It encompasses various conditions like acute arterial mesenteric ischemia (AAMI), acute venous mesenteric ischemia (AVMI), non-occlusive mesenteric ischemia (NOMI), ischemia/reperfusion injury (I/R), and ischemic colitis (IC).

Purpose of the Study:

To correlate imaging findings of different diagnostic methods (US and CT) in detecting mesenteric ischemia.
To evaluate the efficacy of US and CT in identifying various causes of mesenteric ischemia.

Main Methods:

Retrospective analysis of over 200 mesenteric ischemia/infarction cases investigated with both US and CT.
Evaluation of specific imaging findings including arterial/venous obstruction, bowel wall characteristics, ileus, pneumatosis, free fluid, and parenchymal ischemia.

Main Results:

Differentiating between occlusive (arterial, venous) and non-occlusive (NOMI) causes is crucial for early diagnosis and treatment.
Typical imaging findings for each type of mesenteric ischemia were identified and explained.

Conclusions:

Contrast-enhanced CT is the current gold standard for diagnosing intestinal ischemia but has limitations like radiation exposure and contrast-related risks.
Ultrasound (US), despite its limitations, is a valuable first-line imaging modality for suspected acute mesenteric ischemia due to its safety profile.
