Left Ventricular Hypertrophy Demonstrated by Four-Dimensional Myocardiography by Helical Computed Tomography

Left ventricular hypertrophy demonstrated by four-dimensional myocardiography by helical computed tomography.

We present 4D images of hypertrophied myocardium in patients with essential hypertension, hypertrophic cardiomyopathy with asymmetrical septal hypertrophy, and apical hypertrophic cardiomyopathy using helical computed tomography (CT) ( Figures 1 through 4). Previously, we reported on 4D CT-ventriculography, which can assess right and left ventricular morphology and motion.1 In 4D ventriculograp...

Four-dimensional cardiac image by helical computed tomography.

Ultrasound and MRI are useful in assessing wall motion and systolic thickening with 2D images. Volumetric data of the helical CT provide frozen 3D images. We sought to determine whether helical CT could assess left ventricular wall motion with 3D animation. We have developed a new cardiac application, ventriculography by 4D enhanced helical CT (4D-CT-VG), which can assess wall motion with 3D an...

Diagnosis of left ventricular noncompaction by computed tomography.

Left ventricular noncompaction (LVNC) is a rare disorder in which the left ventricular endocardial surface is not appropriately flattened and is heavily trabeculated. Patients with this condition can be affected by stroke from emboli that originate from these recesses. We present a patient with LVNC who was originally misdiagnosed as having an idiopathic dilated cardiomyopathy. Ultimately, diag...

Lung Cancer Screening by Helical Computed Tomography

Ventricular septum rupture after myocardial infarction demonstrated by multislice computed tomography.

A71-year-old man was referred to the emergency department of our hospital for chest pain associated with intense interscapular pain. At presentation, a significant difference in systolic/diastolic blood pressure between the left and right arm was measured, and shortly thereafter, the patient developed severe hypotension. Accordingly, multislice computed tomography (MSCT) of the chest was perfor...
