概括
使用电影磁共振成像 (cineMR) 来测量带有和没有轨迹的左心室射出分数,有助于区分左心室非紧缩 (LVNC) 与正常变体. 这种功能性评估有助于诊断LVNC.
科学领域:
- 心脏病学 心脏病学
- 放射学 放射学是一门学科.
- 医疗成像医学成像
背景情况:
- 左心室非紧缩 (LVNC) 诊断往往低估了它的形态谱.
- 功能评估紧心肌和超结对于了解LVNC疾病至关重要.
研究的目的:
- 为了评估是否测量左心室 (LV) 体积,质量和射出分数 (LVEF) 带有或不带有磁共振 (cineMR) 上的轨道积分,可以帮助诊断LVNC.
- 为了比较这些测量在LVNC患者与正常的个人与多余的心肌曲.
主要方法:
- 对67名患有超结的患者 (30名LVNC,16名对照) 的回顾性单中心MRI研究.
- 使用cineMR和CVI42软件测量LV体积,质量和LVEF,包括或不包括穿刺.
- 使用统计测试比较功能参数;用布兰德-阿尔特曼分析评估可重现性.
主要成果:
- 除了穿外,LVEF在两组中都是正常的.
- 包括穿刺,LVEF在LVNC中增加了9.8%,在对照中减少了10.9% (P<0.0001).
- 肌肉质量在LVNC中保持稳定,但在包括轨道切割在内的对照中显著下降.
结论:
- 在LVNC患者和对照人群之间,LVEF测量有显著的差异,这取决于是否包括了轨道.
- 这些独特的测量可以作为确认LVNC诊断的辅助临床工具.

Pulse rhythm
Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac muscle...

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,...
Mitral Stenosis II: Clinical features and Diagnostic Tests
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...
Aortic Regurgitation II: Clinical Features and Diagnostic Tests
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...
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...
Dysrhythmias V: Evaluating Dysrhythmias
Dysrhythmias, also known as arrhythmias, are disturbances in the heart's rhythm that range from benign to life-threatening. A thorough evaluation is crucial for appropriate management and involves a comprehensive medical history, physical examination, and various diagnostic tests.Medical HistorySymptoms: Collect detailed information on palpitations, dizziness, syncope, chest pain, and fatigue. Note their onset, frequency, and triggers.Previous Cardiac Issues: Document any history of heart...
