Aortic Stenosis

Preliminary Diagnosis: Aortic Stenosis I. What imaging technique is first-line for this diagnosis? Transthoracic echocardiography (TTE) II. Describe the advantages and disadvantages of this technique for diagnosis of aortic stenosis. Advantages Echocardiographic imaging can define the valve anatomy, the underlying cause of aortic stenosis, and the severity of valve calcification. Doppler echocardiography measures the transaortic…

Arterial Venous Malformations (AVMs)

Preliminary Diagnosis: Arterial venous malformations (AVMS) I. What imaging technique is first-line for this diagnosis? Gray-scale and color Doppler ultrasounds II. Describe the advantages and disadvantages of this technique for diagnosis of AVMs. Advantages Easily demonstrates abnormal blood vessels and abnormal blood flow Well-tolerated examination that is relatively inexpensiveContinue Reading Disadvantages May be difficult to…

Peripheral Artery Disease

Preliminary Diagnosis: Peripheral artery disease I. What imaging technique is first-line for this diagnosis? Ankle-brachial index (ABI) with segmental pressures and waveforms II. Describe the advantages and disadvantages of this technique for diagnosis of Peripheral artery disease. Advantages Simple to perform, well-tolerated, and cost-effective screening examination Segmental pressures help localize the level of disease Dampened…

Renal Artery Stenosis

Preliminary Diagnosis: Renal Artery Stenosis I. What imaging technique is first-line for this diagnosis? Ultrasound II. Describe the advantages and disadvantages of this technique for diagnosing renal artery stenosis. Advantages Inexpensive screening examination that is well-tolerated and widely available. Peak systolic velocities correlate with the degree of stenosis.Continue Reading Color Doppler may demonstrate turbulent flow.…

Mitral stenosis

Preliminary Diagnosis: Mitral stenosis I. What imaging technique is first-line for this diagnosis? Transthoracic echocardiography II. Describe the advantages and disadvantages of this technique for diagnosis of mitral stenosis. Advantages Most accurate approach to diagnosis Echocardiography reveals leaflet thickening, symmetric fusion of the commissures, and doming of the anterior mitral leaflet. Left atrial enlargement may…
