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 IV: CMRI

483
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,...

Pericarditis II: Clinical Features and Diagnostic Tests

502
Pericarditis is distinguished by inflammation of the pericardium, the fibrous sac that encases the heart. It can be acute, lasting less than six weeks, or chronic, persisting for over three months. Understanding its clinical manifestations and diagnostic findings is crucial for timely and effective management.Clinical ManifestationsWhile pericarditis can be asymptomatic, it usually presents with characteristic symptoms such as:Chest Pain: The most characteristic symptom of pericarditis is chest...

Imaging Studies for Cardiovascular System I:Echocardiography

873
Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion,...

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...

Imaging Studies for Cardiovascular System II:Types of Echocardiography

804
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...

Area of Science:

  • Cardiology
  • Radiology
  • Medical Imaging

Background:

  • Pericarditis diagnosis and management require accurate assessment of inflammatory activity and chronicity.
  • Transthoracic echocardiography is limited in pericardial tissue characterization.
  • Multimodality imaging offers complementary strengths for comprehensive pericarditis evaluation.

Purpose of the Study:

  • To synthesize guideline-aligned applications of multimodality imaging in pericarditis.
  • To propose a simplified framework for imaging-guided therapy in pericarditis.
  • To highlight common pitfalls and system-level constraints in pericarditis imaging.

Main Methods:

  • Cardiac magnetic resonance (CMR) for pericardial edema and late gadolinium enhancement (LGE).
  • Cardiac computed tomography (CT) for anatomic detail (thickness, calcification, effusions).
  • 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) for metabolically active inflammation.

Main Results:

  • CMR sensitively assesses edema and LGE for active inflammation vs. chronic fibrosis.
  • CT provides detailed anatomy for planning pericardiectomy and managing complex effusions.
  • FDG-PET/CT detects active inflammation in ambiguous or refractory cases, guiding advanced therapy.

Conclusions:

  • Multimodality imaging is essential for accurate pericarditis phenotyping and guiding therapy.
  • A framework using key imaging biomarkers (edema, LGE, thickening, effusion, constriction, fibrosis) enables tailored treatment strategies.
  • Imaging guides treatment escalation/tapering in recurrent disease and patient selection for pericardiectomy.
