Botanical identification of plants described in Mādhava Cikitsā for the treatment of diarrhoea.

Context: Mādhava is regarded as a 7(th) century Indian Physician who composed two treatises (in Sanskrit) on Ayurveda, the Mādhava Nidāna and Mādhava Cikitsā. The former treatise deals with the diagnosis of diseases while the latter with the treatment using medicinal plants and other recipes. In Mādhava Cikitsā, a common Sanskrit name is found to describe two or more totally different botanical plant species (thus leading to ambiguity) and a distinct botanical species is also found to represent two or more Sanskrit names at several instances.

Left ventricular ejection fraction calculation from automatically selected and processed diastolic and systolic frames in short-axis cine-MRI.

The calculation of the left ventricular ejection fraction (LVEF) is dependent upon the accurate measurement of diastolic and systolic left ventricular volumes. Although breath-hold cine magnetic resonance imaging (MRI) allows coverage of the whole cardiac cycle with an excellent time resolution, many authors rely on the visual selection of diastolic and the systolic short-axis slices in order to reduce the postprocessing time. An automatic method was developed to detect the endocardial contour on each image, allowing an automatic selection of the systolic frame.

[Early study of myocardial perfusion with MRI in revascularized infarcts].

The aim of this work is to study the regional myocardial perfusion by MRI early after revascularised myocardial infarction and to compare it with regional function. This prospective work has included 15 patients with acute first myocardial infarction that was precociously revascularised. A myocardial MRI was performed between D2 and D10 after myocardial infarction.

Automatic determination of aortic compliance with cine-magnetic resonance imaging: an application of fuzzy logic theory.

Rationale And Objectives: Aortic compliance is defined as the relative change in aortic cross-sectional area divided by the change in arterial pressure. Magnetic resonance imaging (MRI) is a useful imaging modality for the noninvasive evaluation of aortic compliance. However, manual tracing of the aortic contour is subject to important interobserver variations.
