Clinical MRI of the body has not so far produced results consistently comparable with X-ray CT or high-resolution real-time ultrasound. Present development in MRI technology (new sequences, respiratory gating) and the application of paramagnetic contrast agents are however promising features. MRI might play a useful rôle also in abdominal examination.

We examined the potentialities of Magnetic resonance imaging (MRI) in the evaluation of the main cardiomyopathies: hypertrophic, dilated, restrictive and arrhythmogenic right ventricular. The hypertrophic cardiomyopathy is generally adequately investigated by echocardiography, that well defines the myocardial thickening and the obstruction of the left ...

MRI is a promising tool that can be used as an adjunctive test during the evaluation of patients who have myopathy and can help raise the diagnostic yield of a planned biopsy. It also has promise as a clinical endpoint. This article discusses abnormalities visible on MRI of muscle and the use of MRI in patients who have myopathy.

Cardiovascular magnetic resonance (CMR) imaging is useful to identify systolic dysfunction, particularly when echocardiographic imaging is not acceptable because of poor acoustic windows or when left ventricular ejection fraction (LVEF) is inconclusive by other modalities and an accurate LVEF measurement is needed.

MRI has played a critical role in the evaluation of patients with pancreatic pathologies, from screening of patients at high risk for pancreatic cancer to the evaluation of pancreatic cysts and indeterminate pancreatic lesions. The high mortality associated with pancreatic adenocarcinomas has spurred much interest in developing effective screening ...

AbstractThis study analyzes the signal‐to‐noise ratio (SNR) in magnetic resonance imaging. The factors that determine the SNR are derived starting from basic principles. The SNR, for a given object, is shown to be proportional to the voxel volume and the square root of the acquisition time. The noise generated by the body is derived using a cylindrical

SUMMARYKernicterus (bilirubin encephalopathy) is a disease entity with a very high rate of mortality in neonates. The children who survive are left with neurological deficits such as choreoathetosis, sensorineural deafness and mental retardation. Magnetic resonance imaging of the brain in this condition has specfic findings which aid in the accurate ...

Cholangiocarcinomas are the second most common primary hepatobiliary tumors after hepatocellular carcinomas. They can be categorized either based on their location (intrahepatic/perihilar/extrahepatic distal) or their growth characteristics (mass‐forming/periductal‐infiltrating/intraductal) because they exhibit varied presentations and outcomes based ...

Magnetic resonance imaging (MRI) and computed tomography (CT) were performed in four patients with thorotrastosis. On CT scan, Thorotrast (thorium oxide) deposition was shown as high-density areas in the liver and spleen and the abdominal lymph nodes. These deposits were not found on MRIs. Splenic volume was significantly small due to atrophy.

Osteonecrosis is a relatively common condition, which may be idiopathic or secondary to a variety of clinical situations. It may involve the subarticular region of a joint, when it is commonly referred to as ischaemic necrosis, or the metaphyseal regions of long bones, when it is referred to as bone infarction.
