Insights

3D breath-hold contrast-enhanced MRA (CEMRA) accurately diagnoses subclavian artery issues, showing high agreement with digital subtraction angiography (DSA). This non-invasive technique offers excellent sensitivity and specificity for steno-occlusive disease and vascular anomalies.

Area of Science:

  • Vascular Imaging
  • Radiology
  • Cardiovascular Diagnostics

Background:

  • Subclavian artery pathology requires accurate diagnostic methods.
  • Digital subtraction angiography (DSA) is invasive.
  • Non-invasive imaging alternatives are needed.

Purpose of the Study:

  • To evaluate the diagnostic value of 3D breath-hold contrast-enhanced MRA (CEMRA) for subclavian artery pathology.
  • To compare CEMRA findings with DSA.

Main Methods:

  • Prospective study of 50 patients with suspected subclavian artery pathology.
  • CEMRA performed on a 1.5-T system with Gd-DTPA contrast.
  • Multireader blinded analysis comparing CEMRA and DSA.

Main Results:

  • CEMRA showed optimal agreement with DSA findings.
  • Sensitivity and specificity for steno-occlusive disease: 90% and 95%.
  • Sensitivity and specificity for vascular anomalies: 100% and 100%.

Conclusions:

  • CEMRA is a non-invasive and robust technique for subclavian pathology imaging.
  • CEMRA demonstrates high diagnostic performance.
  • CEMRA can be a valuable alternative to DSA.

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 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...

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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

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...

Angina III: Clinical Manifestations and Assessment

Angina manifests as chest pain, tightness, or squeezing discomfort typically located behind the breastbone. It can radiate to the neck, jaw, shoulders, and inner aspects of the upper arms, most commonly the left arm. Patients may experience shortness of breath, fatigue, profuse sweating, dizziness, indigestion, heartburn, palpitations, anxiety, and vomiting as accompanying symptoms. This pain often lasts a few minutes and is triggered by physical exertion, emotional stress, heavy meals, or cold...

Imaging Studies for Cardiovascular System II:Types of Echocardiography

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 diagnosing...
