Utility of T2-weighted MR imaging and DWI in differentiating benign and malignant liver lesions

Liver lesions represent a heterogeneous group of pathology ranging from solitary benign lesions to multiple metastases from a variety of primary tumours. Liver lesions may be cystic liver lesions or hypervascular liver lesions or liver tumours. For optimal patient management, detection and characterization of focal liver lesions (FLL) is critical. Magnetic resonance with diffusion weighted imaging (DWI)) is a non-invasive technique which could improve the diagnostic accuracy in differentiating between benign and malignant liver lesions by measuring their ADC values. Therefore a study design to evaluate the contribution of imaging science towards the diagnosis of focal liver lesions. Axial sections of DWI and T2WI are obtained in patients with focal liver lesions and the sensitivity, specificity and detection rates of both the sequences are compared individually and together. In this study we are studying characteristic features of liver lesions on T2 and DWI sequence and calculating apparent diffusion co-efficient (ADC) values of focal liver lesions

Role of Magnetic Resonance Imaging in Non Ischaemic Dilated Cardiomyopathies

Cardiomyopathy refers to abnormal conditions of the cardiac muscles. Cardiomyopathies are a significant cause of mortality and morbidity caused due to cardiovascular pathologies. Dilated cardiomyopathy is the most common type of cardiomyopathy. Cardiac magnetic resonance imaging is an excellent modality for diagnosis and evaluation of cardiomyopathies. Non ischaemic cardiomyopathy is a type of cardiomyopathy which has varied etiologies, including and not limited to genetic, inflammatory conditions, auto-immune diseases, stress, infiltrative disorders, drug toxicity, granulomatous diseases and storage disorders. Hence role of cardiac magnetic resonance imaging is important in the diagnostic and research indications in cardiology. Cardiac MRI is a powerful tool in this regard owing to its multifaceted assessment of ventricular structure and myocardial physiology, in matching arbitrary scan planes. Cardiac MRI is routinely performed in experienced centers to complement echocardiography in assessing new cardiomyopathies. It is not only accurate but also highly reproducible. We present a case series depicting cardiac magnetic resonance imaging appearance of non ischaemic dilated cardiomyopathies which presented to our hospital
