Summary
Multidetector computerized tomography (MDCT) effectively visualizes arterial sequestration, a rare congenital disorder. This noninvasive MDCT angiography accurately diagnoses anomalous systemic arterial supply to the lung, replacing older methods.
Area of Science:
- Radiology
- Congenital Disorders
- Thoracic Imaging
Background:
- Arterial sequestration is a rare congenital disorder.
- Diagnostic evaluation using multidetector computerized tomography (MDCT) has not been previously described.
- This study aims to describe characteristic features and assess MDCT's role.
Purpose of the Study:
- Describe characteristic features of arterial sequestration.
- Assess the utility of MDCT in visualizing anatomical features of arterial sequestration.
- Evaluate MDCT angiography for diagnosing anomalous systemic arterial supply to the lung.
Main Methods:
- Retrospective review of seven patients with anomalous systemic blood supply to the left lower lobe.
- MDCT angiography was performed on all patients.
- Systematic image reconstruction including transverse CT, MIP, MPR, and 3D VR for detailed anatomical evaluation.
Main Results:
- All seven cases showed isolated, tortuous arterial anatomy from the descending thoracic aorta to the left lower lobe basal segment.
- Distinctive findings of anomalous systemic arterial (ASA) supply were observed.
- MDCT noninvasively visualized these characteristic findings effectively.
Conclusions:
- Complex CT findings clearly image arterial sequestration and ASA blood supply.
- MDCT angiography demonstrates value and accuracy in diagnosing arterial sequestration.
- MDCT angiography obviates the need for digital subtraction angiography and magnetic resonance angiography for diagnosis.

01:28Imaging 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...
01:30Acute 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...
01:20Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies
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...
01:21Aneurysm 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...
01:25Imaging 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...
01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
