Myocardial Strain Imaging Using Feature Tracking Method of Cardiac MRI: Our Initial Experience of This Novel Parameter as an Additional Diagnostic Tool.

 Left ventricular ejection fraction (LVEF) is used as quantitative parameter to evaluate myocardial function. However, interobserver variation, limited reproducibility, and dependence on pre-load and after-load reduces its accuracy. The fall in LVEF occurs very late, when myocardial dysfunction is already advanced.

Mitral Annulus Disjunction and Arrhythmic Mitral Valve Prolapse: Emerging Role of Cardiac Magnetic Resonance Imaging in the Workup.

Mitral valve prolapse is a commonly described entity with a highly variable and benign course. However, it is associated with ventricular arrhythmias and sudden cardiac death in a small subset of patients. Recent studies have yielded insight into myocardial mechanics and the causation of ventricular arrhythmias in these groups of patients.

Lymphoma in HIV patients: Varied presentations.

Although lymphomas have been reported in patients with acquired immunodeficiency syndrome, it has rarely been reported from the Indian subcontinent. We present three human immunodeficiency virus-infected patients (two adults and one child) who had non-Hodgkin's lymphoma - plasmablastic variety, Hodgkin's lymphoma - nodular sclerosis type II and B cell lymphoma, respectively.

Blood-fluid levels in the brain.

17 cases reviewed prospectively over a period of 4 months highlight the varied appearance of blood-fluid levels in intracranial cystic lesions of different aetiologies; a finding which has not featured significantly in the medical literature. Four types of intracranial cysts demonstrating blood-fluid levels have been categorised according to the nature of the pathology, i.e.
