Anxiety is a debilitating symptom of many psychiatric disorders including generalized anxiety disorder, mood disorders, schizophrenia, and autism. Anxiety involves changes in both central and peripheral biology, yet extant functional imaging studies have focused exclusively on the brain. Here we show, using functional brain and cardiac imaging in sequential(More)
Recent developments in renal magnetic resonance angiography (MRA) have led to a significant improvement in the technical success rate and diagnostic accuracy of the methods. Specifically, three-dimensional contrast-enhanced MRA methods have been shown to provide a more reliable depiction of renal artery morphology than do older MRA techniques. In addition,(More)
A case of lymphoma of the adrenal glands is presented. Both computed tomography (CT) and magnetic resonance imaging (MRI) demonstrated large bilateral adrenal masses with no other associated abdominal abnormalities. MR was better able to demonstrate inferior vena caval patency than CT, and effectively exclude pheochromocytoma as a differential diagnostic(More)

Magnetic resonance angiography is a new noninvasive technique capable of imaging the renal arteries without nephrotoxic contrast agents. Therefore, it may play an important role in patients with suspected ischemic nephropathy. The objective of this discussion is to review the current state of the art of renal magnetic resonance angiography, including a(More)
